Technology of Pesticide Application and Food Security

The application of pesticides plays a very important role in agricultural production. Pesticides are essential in order to maintain the supply of food, however, they spoil the quality of agro-products and pollute the environment. The negative effects of pesticide use are closely related to pesticide application technology. While improving environment and enhancing agro-product quality, western countries set up integrative regulations and policies to promote the innovation of pesticides application technology for reducing pesticides dosage. These measures greatly enhanced the efficiency of pesticide application and ensured the residues under standard level. Since loosing control of pesticide application quality and lack of corresponding legislations in China, farmers usually control pest by putting more pesticides than crops needed. This is the basic reason of high pesticide residues in our agro-products today. To deal with this problem, some measures are needed to take. Firstly, it is needed to establish necessary regulations and policies to limit pesticide dosage used on unit arable land; Secondly, it is necessary to set up a system for farmers to purchase pesticides in terms of their arable land area without exceeding the amount permitted; and lastly, it is essential to strengthen training to pesticide applicators, only those who have the certificates after a success training can spray pesticides. When these three measures are put into effect, farmers' enthusiasm will be inspired to improve their pesticide application techniques and to invest on higher quality spray tools. It is predictable that pesticide application situation will be improved obviously when above measures go to practice.
