How to operate the sprayer

When spraying, start from the leeward direction, and the walking route should be separated by a certain distance, which is the spray pattern. The size of the spray fan should be flexibly controlled according to the size of the wind speed. When the wind speed is small, the spray width should be smaller, otherwise it should be larger, generally 3 meters to 3.5 meters is appropriate. The spraying time is best to choose in the morning, afternoon or cloudy, to avoid the hot sun. It is best to use systemic agents, fumigants or stomach poisons for ultra-low-volume sprays. The dosage is generally about 50 grams per mu. If you need to add a proper amount of water, you can use the "equivalence method".
