Space Spray Insecticide
insecticidal space spray method is the use of spray to spray pesticide liquid droplets dispersed suspended in the air, landing on crops or other processing random application method, it is one of the important application methods to control agricultural and forestry pests, can also be used for the prevention and control of sanitary pests and disinfection.

Spray Attention to the Problem
Pay attention to improving the wet development performance of liquid medicine. When the pesticide was sprayed, the adhesion of emulsion and oil on the plant was strong, while the adhesion of water and wettable powder was poor. In order to improve the efficacy, a small amount of neutral detergent can be added as the developing agent to improve the wet developing ability of the pesticide when it is sprayed with insecticides, dimethyl tetrachloride, glyphosate and other pesticides. In some herbicides, adding an appropriate amount of ammonium sulfate, can improve the ability to develop, such as dimethyl tetrachloride with 0.5% ammonium sulfate, the absorption time reduced from 24 hours to 10 minutes.

Attention should be paid to the water quality of diluted liquid. The hardness, alkalinity and turbidity of the water have a great influence on its efficacy. The stability of the emulsion and suspension prepared by an ionic emulsifier will be destroyed when the calcium and magnesium salts in water are too much.
