The background technology is as follows:
pesticide drift is a main factor causing waste of liquid medicine and environmental pollution, and is also an important index for measuring the quality of spraying effect. The related data show that the disease, insect and pest control on crops can recover 10% -20% of yield loss, but in practice, only a very small part of sprayed pesticide can reach a target to be controlled. The foreign scholars make estimation that only 25% -50% of pesticide sprayed from the pesticide application apparatus can be deposited on crop leaves, wherein less than 1% of pesticide can be deposited on target pests, and the pesticide dose truly playing a role in pest killing is less than 0.03%.
China is one of countries with the largest pesticide production and usage in the world, and the total pesticide usage in 2009 is 128 ten thousand tons. Because the current Chinese pesticide application apparatus and pesticide application technology are relatively backward, the traditional spraying system has the main defects of serious drifting phenomenon, 70% -80% of pesticide applied is lost to the surrounding environment such as air, soil, water system and the like, a large amount of pesticide is wasted, sensitive crop phytotoxicity, human and animal poisoning and environmental pollution are caused, and the working quality of agricultural pesticide application is reduced to a certain extent. People and livestock poisoning caused by improper use of pesticides and medicines in China is as high as tens of thousands of times each year, and a considerable part of the poisoning is caused by 'drift poisoning'. Therefore, for economic, environmental and safety reasons, it is desirable that the spray system have good anti-drift properties, minimizing its amount of drift.
