Paddy herbicide phytotoxicity reasons

In recent years, caused by the rice herbicide phytotoxicity to help things happen quite frequently , and the degree of injury increased from year to year . Many farmers suffer injury , holding natural attitude , not active treatment , the results suffer aggravation . Light brown rice plants of coke , stop growing ; severe dead plants and economic losses .
One , resulting in injury reasons
1 herbicide used improperly . Mainly some farmers to herbicides can not understand the blind abuse causes injury. If using herbicides wrong for upland rice fields specified in transplanting herbicides used for throwing field , live Tin .
(2) the amount of back pack sprayer spraying is not accurate. Herbicides must strictly follow the prescribed dosage administered medication is easy to produce excessive or uneven spraying injury .
3 application time inappropriate . High temperatures , strong sunlight , air dry, rain or dew is dry spraying , easy to cause injury occurred ; sensitive to herbicides in rice during medication, but also easily lead to injury .
4 Application methods unscientific . The use of herbicides , be sure to look him fine manual , as required operation. Such as the use of molinate , butyl benzyl and other types of herbicides, rice fields must be shallow layer of depth to height does not reveal the mud, do not submerge the lower leaf seedlings as well, and water for 5-7 days .hand sprayer If not at the required method of operation , can easily lead to injury.
5 intentional poisoning , resulting in injury. This situation is more special , more occurred in recent years . Generally because there is a dispute , the other party who were secretly cast herbicide , resulting in serious injury.

Pesticide spraying techniques

Spraying pesticides to control pests in many ways, can generally be sprayed and how much ( ie, the level of capacity ) , pesticide formulation types ( liquid, powder, etc. ) , as well as spray atomization principle applied to cloth method for classification. Pesticide Science, technology used essence , is to improve the pesticide on the target (i.e. target ) on the deposition rate , lower or regions in the non- target deposition , adopt the advanced application techniques to reduce the amount of pesticide applied to the minimum effective dose , maximize the effective utilization of pesticides , while minimizing pesticide application personnel and the environment against pollution .

Modern technology development direction pesticide use mainly traditional high-volume low-concentration spray high concentration to low volume spray method development ; big droplet spray fine mist spray to develop . Droplet distribution density is related to the effect of an important factor in prevention , per square centimeter droplet on the surface 20 can achieve the desired control effect. The same amount of liquid, if the droplet size by half , and the resulting 8 -fold increase the number of droplets . High concentrations of low-volume spray of fine droplets in a significant increase effective utilization of pesticides , while also improving efficiency, reduce labor intensity , saving water resources. And China is currently the most widely used high-capacity spray or spray method , tend to wet the crop to a " drip drop drug " phenomenon is not only wasteful , but can not reach a better control effect.
One , knapsack sprayer application techniques . Sprayer our current annual production capacity of 800 million units , brand , style a lot, but are of the same type , in particular, is just a tangential nozzle centrifugal kind of completely different different crops suited to control pests needs. With the domestic market development backpack water sprayer , high-grade , effort, medicine section of the new sprayer has emerged as a variety of spray guard card , configure all good atomization effect , is an ideal plant protection machinery products. Using manual sprayer spraying should pay attention to the following questions:
1, select non-drip phenomenon , good spray atomization , droplet density in guarantee case , to minimize the amount of spray . Prohibited the nozzle removed, and take rain France spraying.
2 , to strengthen the pesticide on crops wet adhesion , can add a small amount of liquid detergent and other types of wetlands development agent.
3, for different crops in different pests , use of different spraying parts. Currently widely used in tangential centrifugal nozzle, spray because of its large amount of structural relationships , the error is also large , uneven distribution , can only extensive pesticide spraying , no longer meet the technical requirements of the scientific use of pesticides , to gradually promote the use of vortex core or vortex -piece nozzle. Fan nozzle fog droplet distribution, spray can avoid re-spray leak phenomenon, spraying herbicides should vigorously promote the use of fan fog nozzle.
4, to change the current direction of travel along the right and left common bilateral "Z" shaped cross chemical sprayer spray habits, promote downwind side "Z" shaped spray application personnel to ensure that the area where no drugs area. Fog nozzle with a fan , you should take unilateral parallel advance of France spray nozzle swings should be avoided .

Precautions formulated pesticides

Jiyong formulated pesticides because running water running water impurities , with its easy to plug the sprayer dispensing nozzle, while also undermine the suspension of liquid precipitation .

Hanged pesticide preparation as well water well water contains minerals more, especially calcium , magnesium and more, these minerals mixed with liquid and reduce the efficacy prone to precipitation .

Avoid any increase of the water because of too much water will reduce the concentration of pesticides , so that the reduced efficacy or even completely ineffective. In addition , excess water will result in the loss of pesticides and environmental pollution .

Bogey in the rain spraying windy days or when the sun will make the powder or liquid pesticide drift , pesticide garden sprayers spraying and rain erosion and reduce drug efficacy susceptible to rain , spraying in the hot sun , plant metabolism, stomatal opening , prone to injury and easy to make efficacy volatile , lower control effect. Optimum application time is 8-11 am , 3-6 pm .

Also note : when you mix several pesticides , not every kind of medicine plus all add water once , but with a variety of drugs are used to calculate the concentration of water . Such as the preparation of urea and 500 times 1000 times thiophanate-methyl , is to use two copies of thiophanate-methyl urea plus 1 plus 1000 parts water. Should be watered with the mother liquor , the first with a small amount of warm water to melt the liquid ,fruit tree sprayer add water to the desired concentration in order to fully dissolve , increasing suspension, improve efficacy and prevent injury.

Paraquat and fine grasses g can not be ignored

Paraquat is a herbicide quick Destuctive tag , can be used in no-till corn or late adult weeding weeds . Wheat harvest , without plowing , direct sowing corn per acre with 15% pre-emergence agent

265 ~ 400 ml, watered 20-30 kg back pack sprayer spray. Do not let 24 hours after spraying spraying livestock into the area . People wrongly poisoning should immediately induce vomiting and sent to hospital for treatment .

Quizalofop ( fine grasses g )

( A ) the cause of the injury . Stem and leaf processing corn Quizalofop sensitive , mistakenly applied or adjacent land spraying, spray drift to corn plants will produce injury.

( Two ) phytotoxicity symptoms. With herbicides stems, leaves processed , beginning chlorotic leaf base from the heart , leaves appear water-soaked spots, yellow purple and gradually dry up . Base necrosis , gently pull that one off from the leaf base , broken occurring after soaked brown . Seedlings dead about two weeks .

( Three ) injury prevention and mitigation measures . Quizalofop not be used for corn . Neighboring land administered Quizalofop should allow enough distance isolation belt, pay attention to wind direction and speed when spraying , to prevent the liquid float moves cornfield. Once water pressure sprayer spraying serious and should be promptly replant.

Clean the roof should be particularly soft

Roof dirt usually accumulate visible place, coupled with high temperatures in summer rain fermentation, will make people felt very depressed. Roof cleaning methods should be based on headliner material, different colors and treated differently. If not timely cleaning, hand sprayerspermanent stains may occur, and if cleaned improperly, it may damage the roof, such as roof off the fabric surface.

Light-colored velvet seats headliner fabric cleaners should be used. Cleaning should be preceded by the seats prostrate, then towel or chair cover to cover, to prevent the roof dripping water or detergent contamination. And then poured into water and portable sprayers spray detergent liquid, spraying the roof. After a little foaming cleanser gently scrub with a brush. Note that using a soft brush and lighter than the intensity, or easy to pilling, but also hurt the roof. Wait until the dirt floating on the surface, then use a towel wrung wipe the foam. The rest of the dirt, can be removed with detergent.

If the material is a vinyl roof, there is usually a lot of small surface pits. The roof of this material is easier than the fabric roof falling dust, but as long as no incorporation of silicone glass cleaner can remove dirt.

Dark lines headliner want to check the extent of its dirty, just use a clean wet towel and gently wipe the surface of the can. If the stick is above the white towel brown dirt, which means that the roof has been dirty. No matter what kind of car every two to three months can use this method check again. If you find that you can wipe clean with a wet towel, then I need to use a cleaning agent.

The use of pesticides should be noted that the hot season poisoning

The majority of pesticide toxic substances, such as improper use or operation are easy to cause human, animal poisoning or produce injury. Hot season, in pesticide use and application process should pay attention to the following questions:

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

2. Mixed drug use tools stirring, how much, how much mix, mix over the drug should be used seed sowing machines. Such as hand or point spread species, you must wear gloves. The remaining virus seed shall be destroyed, can not be used as food or feed.

3. Where the infirm, suffering from skin diseases and pesticide poisoning and other diseases has not been restored healthy, lactating, pregnant, menstruating women, skin lesions healed, shall not be suspended agricultural sprayers spraying or spraying.

4. Use interlaced spray liquid sprayer spraying should not be sprayed on both sides at the same time, we should downwind spray. Winds and midday heat should stop spraying. Medicine liquid can not be overfilled bins, so shake out barrels, the pollution application personnel body.

5. Equipments should be carefully checked before spraying switches, connectors, etc. screws are tightened to prevent leakage drug contamination. Clogging the spray process, application of water to rinse after troubleshooting. Absolute prohibition of mouth pipetting nozzle or strainer.

Sprayers usually Troubleshooting

1, the switch leakage. Switch asbestos gasket wear or abrasion may cause the switch switch leakage, should be replaced with new washers or asbestos.

2, the switch is not flexible. bottle sprayer long home unused, switches and embroidered turbid due to the liquid, remove the switch into the kerosene cleaning, erasing rust, coated with suitable lubricant installed, tighten the switch cap can be.

3, do not play into the gas chamber, under the pressure does not focus on the joystick. May be due to hardening shrinkage or cracking or the cup bottom of the cup nut loosening caused. Cup should be little pressure to open or replace it with new cups, animal oil immersed lubrication after expansion installed, coated with a little oil, and tighten the bottom nut.

4, atomization quality poor. There may home garden sprayer nozzle clogging, the filter casing valve is blocked or out of the water and other contaminants stay put. Should clear the nozzle to remove debris; open the casing if the casing should be cleaned clogged strainer, check valve, remove dirt.

5, automatic air chamber piston rod rose, capping the top to take in water. Or more due to the gas chamber bottom wall cracks sealing off or valve housing glass ball was clogged, not months or cup seal valve damage caused. Application tin welding repair cracks, remove body debris, replace cup.

6, the gas chamber lid gland leakage or water leaks. The reason is skin damage or flange gasket and sealing off the gas chamber, replace the washers or soldering desoldering place.

Sprayer charger and battery use

Electric sprayer Caution:
Charger:
1 Note mildew proof, prevent water,water power sprayer use should be placed in well-ventilated place.
2 Press the logo of the battery "+" negative "-" pole connections to avoid damage to the charger.
Battery:
1 battery can not be disadvantages of using. If the voltmeter pointer from right to left when the junction has been reduced to yellow-green, immediately stop using it, knapsack sprayers when the voltage is not enough.
(2) should be promptly after use rechargeable batteries, such as not using the best supplement it once every three months.
3 Check that the AC charger input voltage is consistent with
