The pesticide was placed in the sprayer medicine box, and the amount of powder discharged was adjusted to about 200 grams per minute.
Third, pay attention to the spraying time: sunny days should be applied in the morning or evening, sprayed on cloudy and rainy days. Applying the best after closing the shed in the evening. In the sunny morning to afternoon, the sunlight is strong and the dust control effect is low.
Fourth, pay attention to the spraying method: spray on the vegetables, whether uniform or not, the effect is very poor. Only a uniform air-to-air powdering effect is good. If the powder is not evenly distributed, some of the powders will not disperse well and the control effect will be reduced.
