First, the "swing" spray in front of the body The shortcoming is that the front spray, people in the environment of sprayed medicine, easy to cause pesticide poisoning. In addition, when spraying the closed herbicide, it is easy to spray unevenly, and the artificial film will destroy the film and reduce the control effect. The "Z" word in front of the hand sprayer should be changed to the side "swing". Motorized sprayers and hand sprayers should be sprayed sideways in parallel when spraying the herbicide.
Second, the large mist spray This spray method will make the spray uneven, especially affecting the control effect of the contact insecticide. The mist spray is also easy to cause the loss of the liquid, and the waste is more serious when the plant is low. Try to use a sprayer with good atomization performance as much as possible, and use a small hole spray to evenly spray.
Third, direct "target" crops Manual sprayers are generally available with direct spray, while motorized sprayers are mist-type, direct spray will greatly reduce work efficiency, can not fully play the characteristics of motor sprayer atomization, high efficiency. The correct method for motorized spray operations should be to apply a drift spray downwind 20 cm above the crop.
