Using the method of backpack garden sprayers

A, use less water Ultra low volume sprayer is used in the pesticide solution, or only after dilution of very low times, so it does not need a large amount of water. Spraying liquid per 100 grams, rather than tens of kilograms, or even hundreds of kilograms. Therefore, when in use, can fruit tree sprayers  reduce the labor intensity, saves labor. Three, droplet distribution Backpack garden sprayers is not the solution directly sprayed on plants, but with the wind so that the diameter is only tens of microns droplet dispersion drift, then around plants "micro flow" effect, the droplet distribution in leaf and the whole plant positive, negative and side. Backpack garden sprayers is not the solution directly backpack garden sprayers  on plants, but with the wind so that the diameter is only tens of microns droplet dispersion drift, then around plants "micro flow" effect, the droplet distribution in leaf and the whole plant positive, negative and side. So, than the large amount of water diluted reagent for higher rate of killing pests, especially has developed resistance to pests to some, better. Because of the pesticide liquid killing function than diluted with water several times higher than even a few times. Four, easy to use Backpack garden sprayers during the spraying hand pump sprayers  in the higher plant height of about 1 meters. Because this kind of spray nozzle saves liquid, liquid outflow to the bottle down. Therefore, when the motor is not open, the bottle should be below the head at the top. During the spraying, should first start the motor, then change the bottle and the position of the head, the bottle at the top, bottle mouth downward, the bottle body is perpendicular to the ground, the medicine liquid can flow automatically. During the spraying, started by the downwind direction, the route to be separated with a certain distance, the spraying range. The size of spraying range should be based on the wind speed and flexibility. Wind hours, spraying range should also be smaller, otherwise should be larger, generally 3 to 3.5 meters is appropriate. Each time in the morning, afternoon or preferably shade, avoid sun exposure. Ultra low volume spraying the best use of systemic insecticides, fumigants or stomach poison. General dosage per 50 grams. For the amount of water available quantity method .
