Abstract:

This article mainly introduced the application of the integrated technology for reducing pesticide use, controlling damage and enhancing efficiency based on green prevention and control of rice pests and diseases,which has been carried out in Changxing County since 2013, and summarized its demonstration experience and achievements. The specific summary was as follows. In the prevention and control of rice diseases and pests, the growth characteristics of rice, the damage features of diseases and pests, the control effect of natural enemies, and the mechanism of action of pesticides should be fully considered. Ecological management technologies mainly focused on the protection and utilization of natural enemies should be given priority to promote the biodiversity of the farmland environment. By combining and applying non-chemical control techniques such as fitness cultivation and physical and chemical induction and control, the stress resistance of rice can be enhanced and the base number of disease and pest occurrence can be reduced. In addition, the scientific application technology of using highly efficient, low-toxicity and low-residue pesticides for phased emergency prevention and control of diseases and pests can effectively improve the self-control ability of the rice field ecosystem, reduce the use of pesticides, control the damage caused by rice diseases and pests, improve the quality of rice, increase the efficiency of rice production, and promote the high-quality and efficient development of the rice industry.

Key words: rice pests and diseases, green prevention and control, pesticide reduction
