Operation method of ultra-low volume spray
When taking medicine, starting from the downwind direction, the walking route should be separated by a certain distance, which is called the spraying amplitude. The size of the spray should be flexibly controlled according to the wind speed. When the wind speed is low, the spraying amplitude should also be smaller, otherwise it should be larger, generally ranging from 3 meters to 3.5 meters. It is best to choose the spraying time in the morning, afternoon, or cloudy days to avoid direct sunlight exposure. For ultra-low volume spray, it is better to use internal inhalation, fumigant or stomach poison. The dosage is generally around 50 grams per acre. If an appropriate amount of water is needed, the "equal amount method" can be used.
