Spraying pesticides job the right way

Significantly increased over recent years, crop pests, pesticide use increased, many farmers in field operations has formed a fixed manner. But from a scientific point of view, farm sprayer pesticides, there are still some errors:

First, the front of the body, "the" word swinging spray. Disadvantage is that the front spraying, people in the drug environment sprayed forward, likely to cause pesticide poisoning. Further, when spraying herbicide closed, easy uniform spray, artificial membrane damage after treading to reduce the control effect. Sprayer should be changed right in front of "the" word of swing sideways "s" word swing. Motorized spraying and spraying herbicides should be taken parallel advance spray.

Second, the large droplet spray. Make spray uneven, particularly those affecting tag insecticide control effect. Large liquid droplet spray is also easy to cause the loss of plants low, the waste is more serious, you should try to use a good spray atomization performance, the use of spray holes tablets, a small droplet spray evenly.

Third, the jet "target" crops. Direct spray sprayer can be used generally, and motorized sprayer to mist type, direct spray will greatly reduce the work efficiency, can not be fully motorized weed killer sprayer good atomization characteristics of high efficiency. Sprayer job the right way should be 20 cm above the crop, spray drift downwind implementation.

Fourth, the liquid sprayed from dripping on the extent of the blade. According to scientific determination of liquid drops on the leaves, the liquid precipitation was only 50% of the maximum amount of precipitation can not maximize the efficacy and caused a lot of pesticide waste. It should be evenly sprayed, try not to have liquid dripping.
