1. Check and adjust the spray machine before the operation, check whether the medicine box and the nozzle are leaking, whether the connection part is tight, whether the transmission part is flexible, whether the pipeline is smooth, whether the spray pump pressure is normal, and whether the spray volume of each nozzle is consistent.
2. According to the determined field spray volume and the flow rate of the nozzle, the operating speed should be controlled at about 4 km/h and proceed at a constant speed. Faster than enough, slow to cause phytotoxicity. Avoid heavy spray and leak spray.
3. Master the spraying time. When the temperature is high, you should avoid the time from 11:00 am to 2:00 pm, so as to avoid the high temperature evaporation and reduce the efficacy.
4. The driving direction of the unit should be perpendicular or at an angle to the wind direction. Start with the downwind first, and stop working when the wind speed is greater than level 3.
5. Spraying workers should wear protective clothing, protective masks and masks to prevent exposure to drug poisoning. Mark the place where the medicine is sprayed to prevent poisoning of humans and animals.
6. Drinking water, diet, and smoking are not allowed on the job site; the naked part of the human body should avoid direct contact with the drug. After work, hands, feet, face, nose, mouth, etc. should be washed clean. Shoes, hats, gloves, masks, overalls, etc. are not allowed to be taken in the house without cleaning.
7. After the end of the operation, the machinery should be cleaned at an appropriate location to prevent contamination of the water source.
