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.

Common botanical pesticides in organic vegetable production application

In conventional agriculture , plant pest and disease control rely mainly on large-scale use of chemical pesticides , which is caused by harmful residues major cause of pollution . With the development of international agricultural trade and national awareness of food safety standards, pollution-free food production is rising rapidly . Production of pollution-free food , the first problem to be solved is the chemical pesticide residues pollution problems, namely the prohibitions and restrictions on the use of chemical pesticides . Use of existing resources, preparation plant insecticide fungicide pesticide to combat the production of pollution-free vegetables, vegetable pests , no residue , no pollution, no adverse effects. Many different types of plant pesticides , are cheap and easy to get a brief introduction of several botanical pesticides.

( A ) chili peppers are widely grown in our country , ripe fruit has insecticidal effect, but outside of the seed coat and the highest content of seeds pesticidal substance .

Mode of action : stomach poison ,portable power sprayer insecticide , poor feeding, fumigant.

Control target: various vegetables aphids, whiteflies and other caterpillar .

Usage: chili powder into powder , add water and stir 50 times , overnight , filtered with a cloth sprayed on crops . Or chili grind into a fine powder , add water, add soap flakes or liquid soap , stir , sprinkle on crops .

( Two ) Garlic Garlic widely planted in the fields , gardens and courtyards , the various parts of the plant contain the active ingredient allicin sterilization .

Mode of action : to kill bacteria, fungi and nematodes .

Control target: vegetable root-knot nematode , Botrytis , bean rust, angular leaf spot of cucumber , melons and potatoes anthrax storage diseases .

How to use: 1kg peeled and smashed garlic , add water 2kg, soak 0.5 hours and then filtered to the residue Serve. With a 20-fold when diluted with water spray can.

When there is a peeled garlic processing step , peeled , first cut pedicle garlic , soaked in water for 24 hours immersion cylinder , then remove and peel . Garlic bulb contains a lot of water allicin, can use this water clarification to the complex, liquid sprayer sprayed directly control a variety of diseases , and would be the utilization of waste .

Pollution safe use of pesticides in tea production technology

Pollution-free tea garden pest control , to use modern concept of sustainable development of agriculture , starting from the tea garden ecosystem , integrated application of various control measures , promotion of sound public control techniques . You must use agricultural control, prevention and treatment programs to be well in advance , the preferred type of biological pesticides and environmental compatibility of pesticides, the rational use of pollution-free tea production procedures recommended by the chemical pesticides, and earnestly control records.
Sound control measures: pollution-free tea harmless pest control measures have public agricultural control , physical control , biological control . Sound public control measures will not cause environmental pollution, will not bring the problem of pesticide residues , therefore, should be given priority .
The use of biological pesticides or pesticide environmental compatibility type : commercialization of biological agents : eg Bacillus thuringiensis BT preparations, Ectropis virus preparations, tea caterpillar virus preparations, whitefly fungi . Botanical pesticides such as Toosendanin , matrine , nicotine , rotenone , pyrethrin and so on. Half the amount of lime mineral type pesticides such as Bordeaux mixture . They are the first choice for future tea pest control agents .
Rational use of chemical pesticides : For the control object , select the appropriate pesticides and formulations. Strict accordance with the provisions of the dose, frequency , method of administration , application suitable period , safety interval , and precautions applying pesticides should be a multi- drug treatment or a reasonable mix of pesticides , prohibited the use of prohibited pesticides.
Prevention and control targets, home garden sprayer spraying suitable period : pollution-free tea production technology point of the main indicators of pest control , control period described. Chemical control , should give serious consideration .
Pesticide varieties : There can be restricted to the use of efficient , low toxicity , low-residue pesticides . Prohibit the use of limited DDT, BHC , parathion ( 1605 ) , methyl parathion ( methyl 1605 ) , methamidophos , acephate , omethoate , sodium pentachlorophenol , chlordimeform , g Budweiser, dicofol , isocarbophos , cyhalothrin , to Fu Ling and mixing agents highly toxic , high residue pesticides.
Application methods : conventional agricultural sprayers, choose low-capacity spray. Punta tea bushes sprayed surface sweep ; tea leaves to take the lower lateral low-volume knapsack sprayer spraying pests . The amount of pesticide safety interval : in strict accordance with GB4285, GB. T8321 into ( Appendix C of pollution-free tea can be used pesticides and their safety standards ) is required to control the amount of pesticide safety interval .
Non- fossil sources of pesticide use production season : such as: lime half the amount of Bordeaux mixture and so on.

How to solve the problem fruit injury

Damage to plants pesticides divided into acute and chronic. Acute injury in a few hours to a few days of irrigation sprayer spraying that manifested , such as blades ( fruit ) spots , yellowing, chlorosis , wilt , leaf , leaves drop, DPC clusters and so on. Chronic drug after a long time before depriving manifested as reduced photosynthesis , flower bud formation and fruit ripening delay , small , deformity, color and flavor deterioration . Once fruit trees suffered injury, the following measures should be taken immediately to rescue .
1 , spray potassium permanganate . Potassium permanganate is a strong oxidant , a variety of chemical substances having an oxidation decomposition. 6,000 times spraying potassium permanganate solution , which can effectively alleviate the injury.
2 , rinse with water. Most chemicals are not water erosion, if the injury caused by excessive pesticide concentrations , use foam sprayer filled with water , washed repeatedly toward the fruit leaves to wash away the residue of the drug to the blade surface .
3 , pause with similar drugs . Before the injury completely removed to minimize the use of pesticides, especially to stop using pesticides similar to avoid aggravating the injury .
4 , followed by fertilization of water . Fruit injury occurred after watering should be combined with fast-acting fertilizer supplement , and Row crop cultivators . Meanwhile, spraying should be 0.3-0.5% and 0.2-0.3 % potassium dihydrogen phosphate, urea , etc., in order to improve the nutritional status of fruit trees , and enhance root absorption capacity . Operation , should be in before 10:00 and after 16:00 .

America should care Lecture Hall

In fact, good skin is not necessarily expensive skin care products can only be done when the folklore of many small recipe can also play a good role. Today, the United States should give a series of lectures Church skincare collection to recommend a few small recipe , let MM have easily have perfect skin .

Recipe 1 : Using vinegar and glycerin

Facial cleansing done every night before bed after working in five parts vinegar with one part glycerin into a mixture ratio , smear on the face and neck , you can sleep overnight , but also in half an hour and then rinse with water after PME Church with the moisturizing beauty cream whitening series , over about two weeks , the skin clear white slip .

Also in the face after the mixture is sprayed with a sprayer to the hands , remember to hand, then both hands pat the forehead , cheeks, chin and other parts , do not get eyes . Less the amount of the first use , the skin does not adapt , there will be some irritation, do not worry, these are normal reactions.

The principle is that recipe , vinegar and glycerin can not only health care , there are many cosmetic effect , in ancient times there with vinegar medicine medical records , that it has hair growth ,backpack garden sprayers  beauty, blood pressure, lose weight. Want moisturizes the skin , the key is necessary to reduce the body's garbage peroxide and can not be excluded .

Recipe 2: salt whitening a coup

Salt in every home in the kitchen are able to find , is one of the ingredients intake every day , while salt is a natural skin whitening products saint .

A certain amount of salt mixed with water , brine in the face with a cotton pad dip gently smear when rubbed salt in the face , can effectively eliminate the accumulated fat face pores , pimples , blackheads , dead skin and so on. However , after the first wash , you may find the face is still too greasy, oil and grease is actually discharged grease your pores not wash clean . About a week or so , your face will be presenting a rosy transparent feeling.

Salt in addition to remove dirt , as well as anti-inflammatory effect , used to fade acne face wash can accelerate the speed . When coupled with lemon juice as an ingredient can also remove unsightly facial freckles . Method is to wash your face sooner or later , can be moistened with warm water and a teaspoon of salt as a cleanser to gently wash , pressure sprayer then rinse with cold water can be. If you deal with acne can be a teaspoon of salt dissolved completely with warm water , then moistened with a cotton pad and apply to the acne affected area and wrap 2-3 minutes will pick up speed healing of acne . If the removal of freckles , you can add the lemon juice has a bleaching effect , add water to dissolve the salt and coated in the face, after half a minute to thoroughly clean the face with warm water , lemon juice, salt .

Remove stagnant water flower seedlings against pests

Flowers to resume production after the disaster, the following points should take timely measures:

After the storm, the timely removal of pots, planting ground water, avoid prolonged flooding lead to suffocation, yellow leaves, ethylene production, leaf wilt appear carved, falling and so on. Flooded the park can dig drainage ditches or machinery. The park blocks on poor drainage should be dug in the garden outside several storage pits, portable power sprayer will pit water discharge. Flat on the waterlogged depressions parks, fields should be cultivated itself into a permanent bar or table fields.

Floods, soil compaction due to prolonged water and the soil organisms, organic matter, etc., due to anaerobic respiration and fermentation, there lees flavor, it would seriously affect root growth. Should be promptly removed weeds, and 1-2 times plowing (plowing depth should not be too deep, usually 15-20cm appropriate), to release excess moisture in soil, improve soil aeration prevents root suffocation.

Prolonged flooding, soil moisture is too large, easily lead to the occurrence of disease stems and roots, so the post-disaster pest control is particularly important. Such as disaster prone to downy mildew, gray mold, rot, disease, etc., should be strengthened in order to avoid the spread of disease prevention and control. Especially in the facility after breaking soil fertility in different environments, more prone to sunburn, blight, black spot disease, such as anthrax. Should be taken to branches painted white (to prevent sunburn and other stem diseases infection), trigger sprayer sprayed protective agents, such as foliar spray once thiophanate-methyl, carbendazim, chlorothalonil, so as to ensure that branches and leaves intact, and promote photosynthesis.

Crop injury prevention and rescue

As a result of improper use of pesticides crop phytotoxicity , our country has an impact on crop yield and quality and safety of agricultural products of major risks.

Improper use of pesticides why the injury occurred

Synthetic pesticides used insecticide and disease prevention, to kill weeds , because of its affinity with the crop itself is not , it will affect crop metabolism, reduce crop immune function . Therefore, the improper use of pesticides causes crops difficult to find the hidden tag of injury or injury , will inhibit crop growth , leading to malnutrition.

To sum up, there are four issues that affect the rational use of pesticides , one pharmaceutical quality , the second is the use of technology , three are standard spraying machine , garden pressure sprayer spraying machine 4 is to regulate the use of technology . In addition, the natural environmental conditions such as low temperature , high temperature and drought , salinity and other effects , can lead to injury incurred or aggravated injury.

Types of injury

Pesticide phytotoxicity divided recessive injury and expressive injury. Recessive injury is caused by the absorption of pesticides , phytotoxicity symptoms generally obvious, often at low temperatures inhibit the performance of crop growth , dark green leaves , and then when the temperature leggy , greed green late , resulting in crop yield and quality decreased . Performance of herbicide injury symptoms, easily recognizable , trigger sprayer spraying in high temperature conditions typically exhibit leaves burns spots, leaves Kujiao other symptoms.

Water mist system development

Water mist fire suppression technology in the application of fire began in the 1940s, which was mainly used for special places, such as transport and so on. At that time, water sprinkler technology development and research as the main direction of water mist fire suppression technology has not been studied in depth, it has been developing more slowly.back pack sprayers As science and technology progress, the people fighting against the concept of change, especially found Halon fire extinguishing agent has damaging effects on the ozone layer as well as in 1987 after the signing of the Montreal Protocol, halon fire suppression technology as one of the main alternatives get all the attention and favor. Water mist fire suppression technology in the 1990s before they get leap development.

Many developed countries (mainly Europe and the United States, Japan and other countries) they experienced many years of theoretical and applied research, experimental exploration after it has been successively developed a variety of types of water mist system. And have been widely applied in the relevant fields and places, home garden sprayer there are products to enter the domestic market, and some have been put into use.

China began in the late 1990s, water mist systems for research and development and testing work, tied for the national "Ninth Five" scientific and technological projects. The main reference to U.S. NFPA750 standards combined with China to carry out the practical application of research and development work, have developed so far have been the appropriate water mist system, there are products asked the city.

Look Sprayer Market

knapsack power sprayer: market prospects
Knapsack power sprayer compared with manual sprayers has many advantages: Spray stable and reliable performance, long service life, the use of a wide range of labor-saving, high efficiency. Although the current high prices, market competitiveness in general, but with the economic development and increase the income of farmers and plant protection services are increasingly socialized, Knapsack motorized (electric) sprayer will have a larger space for development.
In the survey, a reporter was impressed by the technical support of the United States, the latest launch of the third generation of intelligent high pressure sprayer champion, according to the staff, said the aircraft as ordinary electric sprayer overcome many defects, since Earlier this year, the market has already sold nearly 30 provinces, municipalities, and exports of Vietnam and other countries. A Jiangsu merchants pleased to say that this product is still sold well, people feel good with the latter, pressure, good atomization, high efficiency, playing in just a few cents a dose, simulate human back box with curved design , burdened by feeling comfortable, the most critical is fully sealed lid, saying that he would spot the entire drug inverted bucket full of liquid, even leak, drew bursts of applause sidelines friends of farmers.

Scientific use of pesticides on tobacco technology

Select the recommended types of pesticides used

In determining the control object, based on the appropriate pesticides should be used. Different varieties and types of pesticides, their mode of action, mechanisms of toxicity, control object and scope is different, and some can be rid of a variety of diseases or pests, and some can only control a certain kind. When using a pesticide, you must first understand the properties of the pesticide and control object, and then prescribe the right medicine, in order to achieve good control effect. For example, the absorption of pesticides ("aldicarb") through absorption of tobacco plants can play insecticidal effect on sucking pests (aphids) effective natural enemies safe, when used according to the uptake of Pharmacy characteristics determine the appropriate use of methods, commonly used fertilizing. Chinese companies buying and selling of tobacco production since 1999 to regulate the tobacco pesticide use, recommended the use of pesticides on tobacco varieties and the use of methods, and the prohibition against the use of pesticides on tobacco varieties. October 15, 2003 has announced the 2004 tobacco pesticide use recommendations.

To understand the biological characteristics and control object damage rules

Comprehensive grasp of the biological characteristics and control object damage rules for selecting the appropriate pesticide formulations morphology, pesticide use and the best time to provide a scientific basis. Smoke tobacco budworm generations lay eggs in the distribution are very different, in the Huang-Huai tobacco area, the second generation of smoke Green eggs distributed more concentrated, mainly in the front leaves, leaf and stems, while in leaves mostly positive, the eggs for 70% of the total amount of eggs, then use pyrethroids 1500 times or "Souls" 4000 times on the leaves and leaf spray, to receive a good control effect. The third-generation tobacco budworm eggs scattered distribution, and insects of irregular, then spraying should be comprehensive and thoughtful. Daily activity of newly hatched larvae, feeding leaves, 2nd instar larvae before very sensitive to insecticides, it is a good time to prevention. 3 years old, the tobacco budworm lurking in the leaves during the day, the night and early morning feeding on leaves, buds and tender stems, spraying and spraying needs to evening to a corresponding increase in volume in order to achieve better results. From the tobacco budworm infestation biological characteristics and laws of perspective, for the effective control of tobacco budworm infestation, you must focus on prevention and treatment of the second generation, its eradication in the two age ago, economical, and effective. Another example, the tobacco black shank disease is soil-borne diseases, the growing season rainfall or watering raindrops splashing through the water spread germs infect roots and lower portions of the first leaves, liquid sprayer spraying should be used in the lower leaves IRRIGATING or spray. However, the production of tobacco growers often concentrated on the upper leaf spraying, a waste of human and material resources, the control effect is not ideal.

Make full use of control thresholds choose the right timing control

Pest control threshold is to achieve the required degree of chemical control. See Kamada little pest damage on the adoption of chemical control or the tobacco plant pests and diseases more serious degree when water power sprayer spraying practices are undesirable. Generally, aphids indicators for each one hundred aphids reached 500, the tobacco budworm larvae control index number for each one hundred more than 10. For most leaf spot damage, the incidence rate of 5%, you need to chemical control; farming according to virus before transplanting, the rosette stage and the flourishing pre-spraying, can be achieved effectively prevented. From an economic perspective, the individual tobacco plant pests and diseases is a normal phenomenon, as long as the economic threshold is not reached, promoting the use of agricultural practices such as timely removal of individual diseases or artificial tobacco plants catch insects to control pests and diseases. Chemical control aim is both to maximize pest control, but also ensures that control costs at the lowest level, so that the two should be fully coordinated, approach or reach the cost of inputs and benefits of the "golden combination of points."

Spraying pesticides remedies

Generally, the corn itself is strong resistance, nicosulfuron a slight phytotoxicity, without treatment, only temporarily inhibited growth of corn, can be restored after a period of time, does not affect the production. If severe injury, need to be addressed, we can use the following measures:

A Timely detoxification in tobacco ethyl phytotoxicity has occurred or is about to occur, to take early measures to detox. On the initial injury on corn plants, watering can manual sprayer spray equipment wash 3-5 times the pesticide residues on plants.

(2) to strengthen field management (1) pouring enough water, prompting a lot of corn roots absorb water to reduce the concentration of the herbicide plant body, relieve injury. (2) appropriate to increase the depth and frequency of hoeing, enhance soil aeration, and promote beneficial soil microbial activity, accelerate the decomposition of soil nutrients, enhance maize root under water and nutrient absorption capacity, so as soon as possible to restore normal maize plants growth and development. (3) spraying large cloud -120 (natural brassinolide) diluted 1500-fold or GA plus 1% urea aqueous solution or spiritual harm, leaf treasure diluted 500 times in the morning or evening dew dry with sprayer to spray both sides of the blade, and promote normal growth of plants, in order to effectively reduce injury. (4) Field corn injury occurs should be combined with water, increasing livestock manure composting facilities, ammonium bicarbonate, ammonium nitrate, urea and other fast-acting fertilizer to promote root development and regeneration, restoring victims corn physiology to reduce tobacco ethyl phytotoxicity to corn damage. But also foliar water sprayer  spray of 1% to 2% urea or 0.2% to 0.3% potassium dihydrogen phosphate solution or Huimanfeng 600 ~ 800 times, resume normal growth favorable for corn. Should also actively controlling other corn pests, in order to improve the ability of maize to resist injury.

If the injury caused by the cornfields too heavy, these measures can not relieve victims extent, you can only take one or switching to other crops destroyed to avoid greater losses.

Agricultural transformation must rely on equipment modernization

At this stage, our focus on the development of sustainable agriculture intensive agricultural products into the following categories:

1 adapt to the development of sustainable agriculture technology development farming machinery products to meet environmental protection, soil fertility, to achieve high-yield agricultural production, efficient (a) mechanical tillage to new products: a joint operation subsoiling machine; 2 high clearance suspension plow ; 3 paddy land preparation, ground joint working machine; 4 farmland clear membrane that joint working machine; 5 straw chopper drive.

How to maintain electric sprayer

Electric chemical sprayer due to ease of use, high efficiency, loved by more and more farmers, greenhouse pest control has become the main tool. However, electric sprayer more "delicate", once in use, improper operation, maintenance is not timely, it is prone to failure. How to maintain, it can prolong the life of spray, the reporter interviewed the work in the sprayer sales Hanjing, he suggested that farmers should do the following.
First of all, the first official use, check all connections for leaks. When used, install water spray test, then loaded agents. Dosing when the first Canadian Pharmacy, add water, the liquid's surface can not exceed the safe water line. Before spraying, electric sprayer opens in advance, so that the barrel pressure up to a pressure of work, to ensure a smooth spraying.
Secondly, the sprayer after use, should be the first to liquid barrels, hose, lance and other components clean, paying particular attention to clear the pump and liquid grease on the bottom of the barrel recess soil. Because the majority of pesticides on sprayers have some corrosion, therefore disabled, to promptly wash it again with lye, then rinse with water. Especially such as Bordeaux mixture sprayed pesticides after corrosive, preferably with lye soaked 1-2 hours. Pay attention to prevent rust. Those who can disassemble the parts, must be removed to wash clean. Lance, nozzle inner wall to use the oil painting, avoid damp rust.
If you do not use the spray near term, the main components should be clean, dry bottles in a cool dry place. If the long-term need, all metal parts have to be buttered, to prevent rust.
In addition, the core component of electric manual sprayer  umps and batteries. Although there are several pumps available in the market, but these pumps are afraid of clogging. So be sure to use a clean flush drugs, be sure to use a small water filter to filter to prevent clogging.
Remind farmers: sprayer after disabling its fully charged battery should be placed in dry shade, dry place, every one or two months on one charge. If you save electricity after a shorter time, then add distilled water inside a timely manner.
