The nose of the hand-held ultra-low sprayer was always maintained at a height of about 1 meter above the plant. Since the sprayer dispenses with liquid sprayers, the liquid flows out when the vial is put down. Therefore, when the motor is not turned on, the vial should be at the bottom and the nose at the top. When spraying, start the motor first, then change the position of the vial and the head so that the vial is on the top, the bottle is down, the bottle is perpendicular to the ground, and the liquid flows out on its own.
When spraying, starting from the downwind direction, the walking route should be separated by a certain distance, which is the spraying amplitude. The size of the spray should be flexibly controlled according to the size of the wind speed. When the wind speed is small, the spraying amplitude should also be smaller, but vice versa should be larger, generally 3 meters to 3.5 meters is appropriate. Spray time is best selected in the morning, afternoon or cloudy days to avoid sun exposure. Ultra low dose sprays are best used with systemic, fumigant or stomach poisons. The dosage is generally about 50 grams per mu. If you need the right amount of water, you can use the "equal method."
