The pest resistance of rice pests needs to be optimized and the prevention and control strategy
Recently, the reporter learned from the National Agricultural Technology Extension Service Center that in 2013, 60 drug resistance monitoring points were passed through 19 provinces (regions) including Hebei, Shanxi, Jiangsu, Zhejiang, Shandong, Henan, Hubei, Hunan, Xinjiang, and Guangdong. The resistance to major rice pests such as rice planthopper and rice stem borer was monitored. The results showed that the main pests of rice had a significant increase in the level of resistance to common control agents in the field. It is urgent to optimize the prevention and control strategies, strengthen scientific use of drugs, do a good job in technical guidance, carry out unified prevention and control, and reduce the risk of pesticide use.
