建立水稻害虫抗药性治理示范区,进行抗药性监测与田间药效验证,了解水稻主要害虫对田间常用药剂的抗性水平,并在此基础上制定了科学合理的防治策略,实行轮换用药技术措施。示范区实施轮换用药防治结果表明:对水稻害虫的防治效果普遍优于农户自防区,且施药次数减少1次;平均每667 m2水稻增产24.9 kg,节本增收96.2元。
Establish a demonstration area for resistance management of rice pests, conduct drug resistance monitoring and field efficacy verification, understand the resistance level of major rice pests to commonly used pesticides in the field, and on this basis, formulate a scientific and reasonable prevention and control strategy and implement technical measures for rotation . The prevention and control of the rotation of the demonstration area showed that the control effect on pests of rice was generally better than that of peasant households in self-defense area and the number of pesticides application was reduced by 1 time. The yield of rice increased by 24.9 kg per 667 m2 on average and the income was 96.2 yuan per day.
