The use of different pesticides

SC (SC)

It is the original drug is dispersed or suspended solids contain a variety of additives in aqueous medium or oil medium, high concentration of viscous flowable formulations. Commonly used in expensive and efficient pesticides, use of conventional spray, but also for low-volume spraying and soaking, etc., which both WP and EC two formulations advantages, but at present the ideal suspension narrow range, in recommended the use of tobacco, 36% thiophanate-methyl colloidal suspension agent.

Agent (AS)

The water-soluble in water directly into the original drug formulations. The formulation process is simple, easy to use, efficacy, and ease of packaging, transport and storage, garden hand sprayers can reduce the pollution of organic solvents, but agent intolerance storage, easy hydrolysis lapse poor wetting, adhesion is weak, Vinca is very long, and There are limitations, not all pesticides can be processed into liquid.

Seed (SD)

Seed are those containing a binder and a certain pesticide or fertilizer plant growth regulating agents encapsulated in plant seeds on the outside and the formation of a solid dosage form of the drug layer. It is often treated seeds can be stored for a short time, usually tobacco seeds are treated with a seed coating. Most of the commonly used Seed preparations contain a variety of active ingredients, with pest control, to provide nutrition and promote plant growth and development role.

Fumigants (VP)

In the appropriate temperature, the use of toxic gases, liquids or vapors generated by the evaporation of a solid in a closed environment, kill pests or pathogens, called fumigation. Called fumigants used for fumigation agents. Fumigants are easily vaporized liquid or solid, some compressed gases. While some soil treatment or portable power sprayer spray process with fumigation, but can not be called fumigants, such as acephate fumigation has some activity, but the main mode of action is to stomach poisoning and toxicity, and therefore can not become a fumigant , there is a real sense of aluminum phosphide fumigant, methyl bromide, etc.

Ectropis occurrence trend prediction and prevention advice

First, the forecast based on

1, the insect population rises rapidly , the occurrence of large, heavy damage . March 20 -28 survey fifteen tea , tea inchworm up to 3 per square meter , a minimum of 0 , average 0.24 ; pressure sprayers April 7-9, 2009 survey Ectropis up to 26 , a minimum of one average 4.6 . Insect population density, rising fast, heavy damage .

In late February and March to early April rain , field humidity, frequently alternating cold and warm . Also, according to weather forecasts four months late, there are 2-3 times rainfall, the temperature rose rapidly , is conducive Ectropis occurrence and hazards.

Second, prevention and treatment advice

1 , control indicators: per square meter Ectropis larvae 4-5 head , instantly drug prevention and treatment .

2, control Time: April 18 -4 at the end of 400 meters above sea level areas were late for 3-5 days. Serious tea interval of 5-6 days in a row with a good two drugs.

3, the control strategies :

( 1 ) Biological control : To ensure safety of the county green , resolutely implement green plant protection , public plant concept, in acres of tea plantations on medication should be used avermectin 80 ml of 2% or 0.5% bitter raw base 100 ml , to achieve both eradication of pests , and protection from predators a virtuous circle.

( 2 ) Chemical control : mu selection of efficient and low toxicity of 2.5% trifluoroacetic cyanuric chloride ( kung fu ) 120 ml or 100 ml of 2.5% bifenthrin .

Choose one of these agents , watered 45 kilograms per mu motorized plastic sprayer , hand sprayer watered 60 kilograms per mu , at 16:00 after a uniform spray. And after treatment interval 7-10 genius for picking.

Compression knapsack sprayer use and maintenance

1, to properly install the back sprayers components. Check all connections for leaks , use, install water spray test , then loaded agents.

2 , official use , the first Canadian Pharmacy , add water , the liquid 's surface can not exceed the safe water line . Spraying before pulling the joystick more than 10 times , so that the barrel pressure up to operating pressure . Not use excessive force when pulling the joystick to avoid the gas chamber explosion.

3 , the initial loading of liquid , due to the gas chamber and spray bar contains water, the spray initial 2-3 minutes of the injected liquid concentration is low, it should pay attention to fill spray , so as not to affect the pest control effect.

4, the work is completed, should be promptly poured barrel residual liquid, and washed with water poured dry , while checking the gas chamber without water, if water, to remove the water connector release water.

5, if the term is not used weed sprayer, the main components should be clean, dry bottles in a cool dry place . If the long-term need , all metal parts have to be spray butter , to prevent rust.

Banana frequency of application

Bananas with annual growth , rapid growth, large growth characteristics , and our climate is characterized by the best banana growing season hot and rainy weather occurs , after the fertilizer is easy to leakage, evaporation loss , therefore , must carry out the banana fertilization Qin Shi Shi thin , focusing on the period re-applied principle.

In recent years ,knapsack sprayer China's banana fertilization increased the number of prevalent than in the past , at least 5-9 times a year , as many as 10 to 20 times. How many times a year fertilization is appropriate then, it has been made ​​a number of banana fertilization experiment , the first component 13 Shi , Shi eight times a second component , the same as the total amount of fertilizer . Results: The first group than the second group of plant stems 15 cm high , 2.7 cm thick ; first group of mid-August as a whole before pumping bud , before the beginning of the second set of nine group smoked ; production in the first group than the second group increased by 10% .

Fertilizer in multiple application, which can minimize wastage , improve efficiency, give full play to fertility. For sandy soil of banana plantations , fertilizers applied in multiple effect is more obvious.

Based on the above , we believe that the banana fertilization is more appropriate for the full year 12 times to 15 times , flower sprayer including heavy fertilizer five times , thin fat 7 to 10 times.

Phytophthora infestans new pharmaceutical spraying period

( A ) seed disinfection after soaking in the diced potato .

( 2 ) Summer in the soil after sowing before .

( 3 ) potato foliage hand sprayers at 15 days after emergence of the first spray interval of 10 days and then sprayed again. After the closure of the line or the early onset of the spray .

Soaking seed disinfection dosage Hilfiger 800 times with 44% , 100 liters ( kg ) water plus 44% Feige Jia 125 ml . Summer with 44% Hilfiger 150 ml / ha. Prevention of late blight postemergence foliage spray with 44% Hilfiger 750-1000 ml / hectare ( acre 50-67 ml ) , or 800 times , 44% of early onset Hilfiger 1050-1200 ml / hectare ( acre 70-80 ml ​​) ,flower sprayer or 600 times, late blight commonly occurs four percent Hilfiger 1200-1350 ml / ha ( 80-90 ml per acre ) , or 500 times . Hilfiger care with Pitt , He Sheng Su mix can increase potato late blight control effect , increasing the starch content and yield .

Vigorously develop new agricultural products, sustainable agricultural development of modern agricultural equipment relying essential.

The core objective of sustainable development of agriculture is the Agricultural Development and the sustainability of resources and the environment of unity , ensure to meet the needs of the present without doing damage to human generations to meet their needs. Sustainable development of agriculture is the key to maintaining self- purification capacity of the environment , sustainable production capacity of soils , crops, high-quality high-yielding ability , which requires a scientific system and land conservation tillage cultivation training system . This is the middle of the key factors is the production tool to enhance productivity , represented , for China this stage is mainly agricultural equipment modernization . Chinese Agricultural Mechanization has changed from the initial stage towards the intermediate stage , China's agriculture has been progress in the natural state of the agricultural economy to the industrialized agricultural economy into a state of the road , how in the industrialized state of the agricultural economy of Chinese agricultural civilization establish a new form of modern science and technology , tree sprayer environmental protection , information and other relevant institutional mechanisms deep-seated change, mechanization , intensive , large-scale agricultural economy into the main features of the form is the Chinese rural construction need to think about an important topic . Chinese agricultural equipment modernization is the fundamental way agricultural transformation .

Fertilizer dosage should be appropriate

Can be used as basal fertilizer , seed fertilizer and top dressing . Than the amount used as a base fertilizer nitrogen, phosphorus and potassium fertilizers smaller. Zinc ( seven water zinc sulfate ) in food crops per acre with 1 to 2 kg , manganese fertilizer ( manganese sulfate ) with 2 to 4 kg , boron ( borax ) with 0.4 to 0.5 kg , molybdenum fertilizer ( ammonium ) only 10 to 25 grams , usually in a serious lack of certain micronutrients plots before applying basal . As with less, and the large number of elements can be fertilizers, soil or organic fertilizer mixed use , or dissolved in water , irrigation sprayer sprayed on organic fertilizer , organic fertilizer along with the application . Fertilizer to seed dressing or fertilizer is mainly used for soaking . Per kilogram of seed dressing with Zn 5 grams or molybdenum fertilizer 2 to 3 grams , with the amount of water-soluble , spray with a sprayer on the seeds , or seeds in the same solution and the solution is stirred , dry sowing. Soaking can be from 0.02% to 0.05% zinc sulfate or borax solution , soaking time of wheat , corn 6 to 12 hours can be soaked rice 1 to 2 nights. Dressing can be applied to the soil , but more common is spraying. Usually 0.1% to 0.3% borax or zinc sulfate heptahydrate , 0.1% to 0.2% of boric acid , or 0.05 % to 0.1 % of the ammonium molybdate solution sprayed twice over.

For annual crops in the seedling to the flowering stage spray every 7 to 10 days time . Fruit trees in bud and flowering water power sprayer spraying. Water-soluble fertilizer can be used as basic fertilizer, seed fertilizer and top dressing , sparingly soluble fertilizer commonly used as base fertilizer. The amount and concentration of fertilizer is not tested in the case can not be arbitrarily increased to avoid poison crops.

How to deal with diseases of peanut seeds

Peanut main diseases stem rot, root rot, crown rot , blight , etc., yield losses due to these diseases is about 20 % -25% , disease prevention and control better approach is systemic fungicide carbendazim seed treatment . China's production of carbendazim 50% and 40% carbendazim WP Carbendazim colloidal suspension agent , the drug treatment of seeds , the seeds can not only eliminate the bacteria inside and outside , but also can protect the peanut seeds , shoots , roots , stem base from soil bacteria infection , as well as some fertilizer effect. Carbendazim gum disease prevention is better than a suspending agent can be of carbendazim wettable powder .

Chemical treatment methods peanut seeds are the following:

First, the drug soil seed : with 50 % carbendazim WP per 50 kg seeds medicine 0.15-0.25 kg ( calculated as the effective ingredient 0.075-0.125 kg ) , the fine powder with 2.5-5 kg dry soil mix even with medicine soil . Peanut seeds wet washing with water , and then layered soil mixing with drugs , to make each and peanut seeds are evenly coated with drugs soil, soil mixed with drugs immediately after planting.

Second, the liquid seed dressing : with 50% carbendazim WP , per 50 kilograms of peanut seeds with medicine 0.15-0.25 kg , add water 2 kg dubbed liquid,backpack weed sprayers  spray with a sprayer peanut seeds respectively , so that each piece peanut seeds are evenly coated with liquid, dry immediately after planting.

Third, the soaking liquid : with 50 % carbendazim WP per 50 kg seeds with medicine 0.15-0.25 kg , add water to 30 kg dubbed liquid, soak peanut seeds 50 kg , cold soak for 24 hours, turning two middle -3 times , can be planted after soaking .

The prevention of the above methods stem rot , blight, root rot results are above 90%, dressing and soaking no significant difference in the effect of disease prevention , but considering the dressing method is simple, or as seed for the good . Pharmaceutical treatment of peanut leaves dark green , robust growth , with an average increase of about 30%, some 50% of production , or even more than doubled, also at least about 10% yield , pod increased 10-20 % , with the increase of the number of drug the amount of the increase , but the amount of medication ( active ingredient ) than 1% of the seed phytotoxicity , emergence effect .

Although peanut seeds treated with carbendazim significantly increase yield and disease prevention , but this did not wilt agents on disease prevention effects of peanut . No use of carbendazim on the incidence of peanut seeds treated plots , if necessary, can also be hand held sprayer sprayed with a 1000 -fold in the seedling stage liquid, preventing effect is also more than 90 percent , an increase of 10% or more, with 500 times the liquid IRRIGATING there certain effects.

Reduce losses should not be spared the daily vehicle inspection

As the car fire was caused mostly by electrical short circuit caused , experts say , whether it is a new car or a used car , the car mainly pay attention condition , careful observation . Once the crisis is now parking stall for self-help . Of course, even the owner of the car ignition prevention "Kung Fu" spent peacetime .

Daily vehicle inspection should not be spared . Make routine inspections of motor vehicles , to prevent electrical circuit malfunction or poor contact , as well as oil spills, leaks and other phenomena , is fundamentally prevent car fires simplest and most effective means. If you do not have a certain knowledge of the electrical and oil , according to the condition should be inspected regularly to the repair shop . In addition , there are rubber paste and abnormal smell or smoke is not the effect even more .

Inflammable and explosive materials are not being prosecuted . Everyday life lighters, perfume, mousse , etc. constitute a dangerous goods vehicle fires . Disposable lighters rough production process , under the sun exposure may be as high local temperatures inside above 50 ℃ , it may cause an explosion fire lighters ; while pesticides, upholstery cleaners , Bo Youqing lotion fruit tree sprayerequally full of flammable gases , it may explode when heated .

Fire extinguisher essential. Many people in the car without the required also equipped with fire extinguishers or with occasional replacement , but most people prefer not used fire extinguishers , which are left for the opportunity to take advantage of the fire , is not feasible. Friends should be familiar with each driver use a fire extinguisher , in order to avoid accidents helpless. According to the reporter , the general car will comes with a bottle of 0.5-0.7 liters of fire extinguishers, but this effect is not obvious spontaneous combustion fire extinguishers to fight the blaze . Fire department reminded the volume of fire extinguishers preferably more than 1 liter , would be difficult to Fight larger fire .

Owners best insurance spontaneous combustion risk . Experts suggest , the age of 4 years of automobile insurance should be considered spontaneous combustion risk , because with the age of the vehicle increases, the aging line for automotive ignition potential problems. Reporters from the Pacific and Ping An Insurance Insurance branch in Jinan , household sprayer Jinan Branch learned that, despite these two insurance company 's customer service center also recently received a number of cases reported in spontaneous combustion risk applications , but almost did not happen claims . Because the owners of these spontaneous spontaneous combustion risk insurance and uninsured .

Plant protection equipment behind pesticide waste Qi Cheng

First, the low level of mechanization . It is understood that the province plant protection machinery social ownership of more than 340 million units , of which there are 3.3 million manual sprayers , accounting for more than 95% , motor and stretcher sprayer social ownership 160,000 units, accounting for about 4.6% , far below the the national average. According to incomplete statistics , at present the province's crop pest control area of ​​more than 70% is done by hand sprayer . What is more , many farmers in the use of water pumps spraying this very rudimentary tools .

Second, plant protection models behind. Currently , the province is mainly used sprayers workers and peasants -16 , WFB- type and peasants -36 type sprayers , fifties and sixties of the last century stereotypes ,back pack sprayers spraying poor performance, single component spray , many products of poor quality, "run , run, drip, drain "phenomenon seriously . And developed advanced anti- drift spray , circular spray , automatic spray machines and other plant protection machinery target , compared with four or five decades gap.

Third, application techniques behind. Since the last century since the 1950s , the international application techniques continue to improve and perfect. A large number of low-volume applications , ultra-low volume , controlled droplet spray , anti- drift spray range of new technologies to improve the efficiency and utilization of pesticides sprayed to reduce pesticide pollution of the environment . The province is basically follow large capacity , rain -style , full coverage spray method , not science .

Less than 30% utilization of pesticides in our province , 70% of applied pesticides drift into the air or into the soil , resulting in a large number of pesticide waste and pollution of the environment , prone to excessive pesticide residues in agricultural and crop injury , but also affects the control effect of pesticides .

Around the pear tree fertilization

Amount of phosphorus and potassium are also applying P and K requirements were larger pear nutrients , each producing 100 kg fruit absorbs about 0.1 to 0.25 kg of phosphorus pentoxide , 0.4 to 0.6 kg of potassium hydroxide . Pear on the results of tests done showed that P and K fertilizer nitrogen is higher than the single rate of 50% to 85%. P and K application can not only improve the pear production , but also to promote root growth , increased leaf photosynthetic products to the stems, roots, fruits and other parts of Collaborative Transportation , while phosphate has a very significant role in inducing root , will moderate phosphate deep application can promote deep roots to the soil stretching, can significantly improve the drought resistance of fruit trees , to reduce the incidence of disease .

Pear in the soil with phosphorus and potassium content is high , increasing phosphorus, potassium , often without fertilizer , only pay attention to nitrogen and phosphorus, potash fertilizer application in order to achieve better results.

Rational application of boron, zinc , iron and other trace elements boron fertilizer can significantly reduce the occurrence of pear fruit shrink disease , improve fruit set and reduce pulp cork zone formation. Boron and boron to potential mild pear , flowering can spraying a concentration of 0.3 % ~ 0.4% borax solution . Serious soil boron with germinating fruit per plant soil application before 100 to 250 grams of borax , valid for up to 3 to 5 years and, once again in full bloom spraying concentration of 0.3% to 0.4 % borax solution , the effect better .

Applying zinc fertilizer on correcting pear leaf spot and leaf disease effect is very significant , generally diseased branches recovery rate of 90 % or more, can improve the rate of pear fruit , pome fruit production increased , and can increase the nitrogen and phosphorus in the leaves the levels of calcium . Spraying more effective method is to use 0.2% zinc sulfate and 0.3% to 0.5 % urea mixture promptly after the onset of fruit tree sprayer spraying , but also in the spring 3 weeks after spraying falling pear , or a 6 % before germination 8% aqueous solution of zinc sulphate spraying can play a preventive role. Soil application of zinc sulphate less effective application of Zn chelate and attitude is better, but the cost is high, generally more cost-effective primary prevention is still spraying . A large number of organic fertilizer to some extent, reduce zinc deficiency may play a role .

For the pear yellow chlorosis to treatment , the most commonly used method is better are: soil application , the use of "local rich iron law ," the upcoming ferrous sulfate and cake ( cake, peanut cake , cottonseed cake ) and ammonium sulfate at a weight ratio of 1:4:1 , basal concentration in fruit bud before applying the thin roots more layers , according to the fruit size and the degree of yellowing , fruit per plant control the amount of application 3 ~ 10 kg . Foliar spraying directly the effect of ferrous sulfate is generally poor , the application of fulvic acid iron sprayed with a mixture of urea treatment etiolated better, but of short duration ; also be applied by 0.3% ferrous sulfate , urea 0.5 % in fruit growing season garden hand sprayers spraying once a week . For local conditions , can also use a strong trunk injection machine xylem ferrous sulfate injection , although the effect is better, fertilizer and rarely , typically only about 1% of soil application , but the method is only suitable for adult fruit , injection dose range is narrow, easily administered improperly influence the normal growth of pear trees .

Herbicide injury diagnosis

Due to steep rice roots, nutrient deficiency or pest , and sometimes there will be similar with herbicide injury symptoms , but through research and analysis , you can still determine whether they are herbicide injury .

From the amount of pesticide low pressure sprayer spraying periods and judgment

If application time after transplanting of rice l ~ 2d, rice case sensitive , sometimes injury. Administered high doses of individual pesticide products are also prone to injury.

Check fertilizer, soil conditions

Irrigation after the drug is too deep ( immersion growing point ) , easy to produce injury . Check whether due to improper fertilization , or administration no decomposition of organic manure, green manure or straw waterlogged field caused by improper growth of plants adverse symptoms appear .

Check pests

Rice thrips and rice food rootworm hazards rice plants will grow shorter , small clusters , tip section tubular roll becomes brown, fibrous roots short . Ordinary rice dwarf virus symptoms are mainly yellow leaves and withered volumes, dwarf plants , began to fade from the top tip , plaques appear broken , but the veins remain green , leaf green and yellow stripes often has the obvious .

Look around fruit tree sprayer spraying seedlings growing

After the normal green rice transplanting ( Li Miao ) , after application such as abnormal symptoms, and adjacent seedling quality with the same species of other plots seedlings grew normally , this may be caused by injury .

Suggestions to improve the pesticide market

For the current pesticide market several major problems, I propose the following recommendations to improve the domestic pesticide usage.

1. Pesticide safety training efforts to increase scientific, training dealers and farmers awareness of safe medication. The grassroots agricultural workers, dealers and farmers for safe and rational use of pesticides knowledge and technology information and training, the formation of a scientific and rational use of pesticides conscious atmosphere. Meanwhile, for the occurrence and control of pests of different crops during the timely organization of scientific and technological personnel to go to the grassroots and providing technical guidance to carry out pollution prevention technology training to enable farmers not only master the techniques of scientific medicine,sprayer but also fully aware of the ecological environment and pesticide contamination harm the health of people.

2. The establishment of safe use of pesticides demonstration fields, visually guide the farmers medication safety. In the demonstration venue, in strict accordance with technical regulations, timely and rational use of pesticides, with minimal dose for maximum control effect, so not only cost effective, but also protect the ecology.

3. Introduction of testing new pesticides, and actively promote the new pesticides. Strengthen the new pesticide testing, demonstration and promotion, screening efficiency, low toxicity, low-residue pesticides, bio-pesticides, to replace the highly toxic, high residue pesticides. Expand insecticidal lamps, sex attractant agent physical, biological technology area, and actively carry out ecological controlling pests and biological control techniques popularized.

4. To promote the introduction of new Equipments, improve the utilization of pesticides. Spraying machine must accelerate the upgrading of application techniques while actively making improvements, changing the traditional high-volume, low-capacity large weed sprayer spray droplets and fine droplet spray. Establishment of specialized defense team, promote motorized sprayer, improve control and reduce pesticide waste and pollution.

5 Strengthening pesticide residue monitoring, production of pollution-free agricultural products. Pesticide residue monitoring job is to protect people's health needs, is to improve the competitiveness of agricultural exports needs, but also the sustainable development of China's agricultural needs. Look perfect as soon as possible pesticide residue testing equipment, staffing, will monitor pesticide residues as a key task.

6. Strengthen market management of pesticides. Pesticide management departments should strengthen law enforcement efforts to rectify the pesticide market, and resolutely fight against counterfeit pesticides, pesticide labels failed to purify pesticide marketing channels for the safe use of farmland to create a favorable market environment. Punished for violations, improve pesticide production, management, legal awareness of users, crack down on illegal production, management, use of pesticides behavior, to prevent illegal pesticide production, management and use, as to create conditions for the safe and rational use of pesticides.

Hot season spraying pesticides security can not be taken lightly

In the spraying period not drinking, smoking , drinking , eating , etc., can not be directly Cazui hands , face, eyes, absolutely not allowed to spray each other frolic . Wash thoroughly with soap after household sprayer spraying hands, face and mouth , pesticide-contaminated work clothes to be washed and replacement bulbs . Pesticide spraying operations staff time per day is generally not more than six hours .

Applying excessive toxicity , pesticide poisoning obvious place to erect signs within a certain time ( harvest interval ) prohibit grazing , harvesting , to prevent livestock poisoning . And pay attention to compliance with the relevant provisions of the safe use of pesticides is prohibited highly toxic pesticides in vegetables, fruit , tea and other use .

After spraying sprayer should be cleaned and kept clean and safe custody ; Guo Cheng Zhongsheng preparation and handling of pesticides packaging materials , centralized processing , nor for holding grain, oil, wine, water and other food and feed.

After water power sprayer spraying fruit and other vegetable crops , must be in a safe interval after harvesting and consumption. To soak and rinse before eating to eliminate pesticide residues in vegetables .

With special chemical properties and performance of pesticides, must be read carefully prior pesticide label on the package , in accordance with label precautions for personal protection and operation.

Precautions in the use of pesticides

1, dispensing, dispensing personnel should wear rubber gloves must be used in accordance with the prescribed measuring liquid or powder dosage said dispensary shall be arbitrarily increased usage. Prohibited by hand to mix drugs.

2, seed use tools stirring, how much, how much mix, mix over the drug should be used seed sowing machines. Such as hand or point spread seed must wear protective gloves to prevent skin absorption poisoning. The remaining toxic species should be destroyed, not allowed to be used as food rations or feed.

3, pharmaceutical and seed should be selected away from drinking water sources, settlements safe place, there must be supervised to prevent pesticides, toxic species lost or people, livestock, poultry eating.

4, the use of drugs should be interlaced sprayer spray jet. Equipments manual and motorized spray can not be on both sides simultaneously. Winds and midday heat should stop spraying. Medicine liquid can not be overfilled bins, so shake out barrels, the pollution of the body application personnel.
 
5, should be carefully examined before portable sprayers spraying the beginning Equipments pick off, sprinklers, etc. screws are tightened, drug barrels leaks to prevent leakage drug contamination. Spraying process, such as clogging, should be washed with water Xian after troubleshooting. Absolute prohibition of mouth pipetting nozzles and filters.

6, the application of high toxic pesticides should be established where signs prohibit within a certain time grazing, mowing, digging wild, poisonous weeds to prevent humans and animals.
7, after the end of treatment, to promptly clean the nebulizer, together with the return of the remaining pharmaceutical warehouse storage, should not be allowed to go home. Cleaning Equipments sewage should choose a safe place to properly handle, are not allowed anywhere spill to prevent contamination of drinking water sources and fishpond. Sheng Guo pesticide packaging materials, are not allowed to use sheng of grain, oil, wine and other food and feed. Installed over empty pesticide containers, bottles, bags, etc. should be centralized. Soaking tanks used to wash central depository.

Introduction of low volume spraying

Low volume spraying, also known as micro-spray, is the use of motorized sprayer DFH type 18, with water or oil as the carrier, the concentration of pesticides in 3-10%, per acre knapsack sprayer spray volume of 0.5 to 2.5 liters, the droplet diameter 80-150 microns, a cumulative spray drift. Less water for a large area pest control, does not apply to agricultural chemical weeding. Micro-spray rain erosion resistant, long duration of advantages, but by the climate impact, spray drift loss of large, relatively strict application techniques, could easily lead to crop injury and livestock poisoning, not commonly used in pest control.

ULV

ULV, also known as micro-spray, is the use of DFH 18 type motor plus ultra low volume sprayer nozzle spray to oil or water as the carrier, pesticide concentration 10-60% per acre chemical sprayer spray volume from 0.15 to 0.5 l, the median droplet diameter of 15 to 75 microns, is a cumulative spray drift. For small water areas, explosive pest control, chemical weed control can not be used for farmland. With high efficiency, saving pesticides, prevention and treatment in a timely manner, without water advantages, but strict operating techniques, the droplet by the flow impact, improper application will produce injury.

We selected agricultural methods are not grasped

Check the appearance of the product: From all directions around to see the whole machine has no distortion. There is no rust where sheet metal is not smooth, there is no leakage of paint, paint flow, without casting porosity, blisters, burrs, plastic colors, the wall thickness is not uniform, tires, belts and other rubber between triangular No deformation aging, there are no leaks, oil spills place. Should be fixed on the equipment nameplate, see the nameplate equipment model is not, and they need the same. Some evidently almost from the appearance, the name is very similar, but can not be used to buy back a little attention. No nameplate, site, basically not a regular production of the company's products, quality is difficult to guarantee.

Security check: national mandatory standards, safety of agricultural products must pass a safety protection device. Like the initiation claws, fan, pulleys, PTO shaft, exhaust pipe, chain drive and the knife shaft assembly parts and so have shields. Pedals should be skid plates, easily hurt in the place you want to paste the yellow or red warning signs. Throttle, Dangba other places, have a significant operation symbols.

To check the quality of assembly: Check the farm throughout parts and components is not complete and not damaged; portable power sprayer installation is not very good. Duly qualified product assembly marks are very clear, obvious, such as the gear assembly marks, piston crown markings should be clear and in good condition. Check all screws, nuts are not all on tight, never use wire or nails instead of cotter pin. All rotating, rotating flexible drive and operating system, without sticking, loosening. If the optional rotary tiller, to see the knife shaft is not rotating flexible, without significant axial movement, catching and abnormal sound, hanging files handy, no missing parts, no leakage. Rotary Blade specifications, models are not unanimous.

Good test machine check: buy tractors, farm vehicles, etc. must be commissioning. Look after starting the engine shake do not shake, the sound is not normal, is it easy to turn off, take no black smoke, Guadang, direction, brake, throttle is not so that; choose manual sprayer (control) is best for simple spray test a trial, such as the water added to the bottle plastic sprayer kits, see the spray mist nozzle spray droplet is small, uniform, does not drip, valves and joints can not "run, run, drip, leak," and so on.

Emergence herbicide injury countermeasure

Chemical weeding efficient, thorough, labor, time, help large scale mechanized operations, efficient agriculture has become an indispensable important measures. However, due to the improper selection or spraying herbicides wrong way, the season or after the crop to cause serious injury to occur. Once phytotoxicity science should take timely countermeasures.
First, rule out the use of herbicides drug excessive drug toxicity, injury has occurred or will occur, to take early measures to detox. Immediately drain the water contained in the field of irrigation, back pack sprayer several consecutive flush with the new irrigation, drainage facilities into lime or a combination of other methods, and in the fields of acidic herbicides, reducing the content of herbicides in soil; medicine for plants harm, the available water irrigation machinery residue leaching of toxic plants, reducing the poison stick on the leaf. Severe poisoning plots should be rinsed after exposure to deep plowing, and then try to grow a small amount of sensitive crops can observe two weeks to prove that no injury again when other crops.
Second, to strengthen field management of crops on plots by the injury, to strengthen field management, the use of fast-acting fertilizer by Shi, scientific management, to reduce the impact of herbicides on crops, to reduce the losses down.
Third, the application of plant growth regulators to promote crop growth plant growth regulator is to promote crop growth agents, it has a good crop growth stimulation, but also help reduce injury.
Fourth, the use of chemical antidotes dressing with activated carbon can reduce or prevent four alachlor, linuron ,weed sprayer 24-D herbicide phytotoxicity to corn, but also in plants before planting their roots or stems dipped in powdered activated carbon, can prevent injury. Planting the crop every 15 mu 10-40 kg evenly spread on the soil surface, can also be sprinkled on the soil surface to prevent local or ribbon simazine on soybean, cucumber, wheat injury.
