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, farmers knapsack power sprayer spraying 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 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 bottle sprayer 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 .
