Ultra-low sprayer, the advantages of controlling flowers and plants and how to use it
Compared with commonly used sprayers, ultra-low sprayers have the advantages of fast speed, high efficiency, light weight, and cost saving in the prevention and control of diseases and insect pests of flowers, trees and lawns. especially:
Low water consumption
The ultra-small volume sprayer uses pesticide solutions or only a very low dilution, so it does not require a lot of water.
Reduce drugs
Spray about 100 grams of liquid per acre instead of tens of kilograms or even hundreds of kilograms. Therefore, the labor intensity can be greatly reduced during use, and labor can be saved.
Evenly distributed droplets
The ultra-small-volume sprayer does not spray liquid directly on the plants, but relies on the wind to disperse the droplets with a diameter of only tens of microns, and distribute the mist evenly on the plants under the "micro airflow". The front and back sides of the leaves and the whole plant. In this way, the killing rate of pests is higher than that of pesticides diluted with large amounts of water, especially for certain pests that have developed resistance. Due to the killing function of the insecticide liquid, it is several times or even several times higher than the insecticide diluted with water.
Easy to use
The head of the handheld ultra-low sprayer is always kept at a height of about 1 meter above the plants. Since the sprayer eliminates the liquid sprayer, the liquid will flow out when the vial is put down. Therefore, when the motor is not turned on, the sample bottle should be at the bottom and the nose should be at the top. When spraying, first start the motor, and then change the position of the sample bottle and the pump head so that the sample bottle is at the top, the bottle is facing down, the bottle is perpendicular to the ground, and the liquid flows out by itself.
When spraying, starting from the downwind direction, the walking route should be separated by a certain distance, that is, the spraying range. The size of the spray should be flexibly controlled according to the wind speed. When the wind speed is small, the spray range should be small, and vice versa. When the wind speed is large, the range is generally 3 meters to 3.5 meters. It is best to choose the spray time in the morning, afternoon or cloudy to avoid sun exposure. Ultra-low-dose sprays are most suitable for use with systemic, fumigative or gastric poisoning. The dosage is usually about 50 grams per mu. If you need the right amount of water, you can use the "equal method".
