Ultra-low sprayer to control the advantages of flowers and lawns and use methods
The ultra-low sprayer has the advantages of quickness, high efficiency, light weight, cost saving, etc. compared with commonly used sprayers when it comes to the prevention and control of diseases and insect pests of flowers, trees and lawns. Specifically:
Low water consumption
Ultra-low-volume sprayers use a pesticide solution or only a very low dilution, so it does not require a lot of water.
About 100 grams per acre spray liquid, instead of tens of kilograms, or even hundreds of kilograms. Therefore, when used, it can greatly reduce the labor intensity and save labor.
Evenly distributed droplets
Ultra-low-volume sprayers do not spray the liquid directly on the plants, but rely on the wind to disperse the droplets with a diameter of only several tens of micrometers, and evenly distribute the mists to the plants under the “micro-air flow” around the plants. Positive and negative sides and sides of leaves and whole plant. In this way, the killing rate of pests is higher than that of pesticides diluted with a large amount of water, especially for some insect pests that have already developed resistance. Due to the killing function of the pesticide liquid, it is several times or even several times higher than that diluted with water.
Easy to use
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."
