Pesticides will be used in the prevention and control of pests and diseases. How to use the right amount to make it play a high-efficiency effect is a problem that farmers' friends are more concerned about. The amount of spray must be mastered. So how to save the amount of pesticides? Today, Xiaobian will give a detailed introduction. Electrostatic spray technology: The method of applying high-pressure electrostatic generating device to spray the droplets, the deposition amount of the liquid droplets on the surface of the blade is significantly increased, and the effective utilization rate of the pesticide can be increased to 90%. Pelletizing and applying technology: For the water-soluble agent used in paddy fields, the pelletizing application technique can be used. The pellet can be evenly spread in the farmland, the work efficiency is increased by a dozen times, and there is no pesticide drift. Contaminated adjacent crops. Circulating spray technology: redesigning the conventional spray equipment, adding a drug recovery device on the opposite side of the spray component, collecting the liquid on the undeposited target plant and pumping it back into the liquid tank for recycling. Improve the effective utilization of pesticides. Roller smear technology: It is mainly used for the internal absorption of herbicides . The liquid is oozing from the surface of the medicine roller through a medicine roller (a smear overflowing with a foam material capable of absorbing the liquid medicine), and only needs to be contacted. The leaves on the upper part of the weed can work. This method can almost completely apply the agent to the surface of the target plant without causing the liquid to spill and drip. Application of computer technology: The computer control system has been used in the United States for orchard sprayers. The system determines the shape of the fruit tree by ultrasonic sensors. The computer control system automatically adjusts the pesticide spray characteristics according to the shape of the fruit tree. This technology greatly improves the effective utilization of pesticides and represents the direction of pesticide use technology. Low-volume spray technology: refers to the constant application of the unit area, the pesticide stock solution is slightly diluted, the water consumption is equivalent to 1/5 - 1/10 of the conventional spray technology. This technology improves work efficiency and is widely used in greenhouses and mountains. More pesticide knowledge , please pay attention to China Pesticide Network Polyvinyl alcohol is a kind of organic compounds, chemical formula for [C2H4O] n, the appearance is white flake solid flocculent or powder, odorless soluble in water (95 above), dimethyl sulfoxide, slightly soluble in benzene, toluene insoluble in gasoline kerosene, vegetable oil dichloroethane carbon tetrachloride acetone, ethyl acetate methanol glycol polyvinyl alcohol is an important chemical raw materials, such as used in the manufacture of polyvinyl acetal resistant to gasoline pipe and vinylon synthetic fabric treatment emulsifier paper coating adhesive glue, etc. Polyvinyl Alcohol Pva,Low Binder Requirement Pva,Low Ash Content Pva,Smooth Burn-Out Profile Pva Xingbang High Molecular Materials Co., Ltd. , https://www.chemicaladditive.com
