How to operate an ultra-low volume sprayer

When spraying, start from the downwind direction, and the walking route should be separated by a certain distance, which is the spray width. The size of the spray width should be flexibly controlled according to 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 best time to spray is in the morning, afternoon or on a cloudy day to avoid exposure to the scorching sun. Ultra-low-volume sprays are best administered using systemic agents, fumigants, or gastrotoxic agents. The dosage is generally about 50 grams per mu. If you need to add an appropriate amount of water, use the "equal amount method".
