水稻是我国重要的粮食作物之一,而纹枯病在南方稻区危害严重,是当前水稻生产上的主要病害之一,其发生面积广,严重危害水稻产量。目前防治纹枯病主要是做好水肥管理,结合药剂保护。而长年使用井冈霉素这一单一药剂容易产生抗性,降低防效。为了筛选出高效、安全的水稻纹枯病防治药剂,为大面积生产应用提供依据,扬中市植保植检站于2014年8月进行17%井冈·嘧菌酯水稻纹枯病的防除试验。
Rice is one of the most important cereal crops in our country. However, the sheath blight is seriously endangered in the southern rice area. It is one of the most important diseases in rice production. Its occurrence is extensive and seriously endangering the yield of rice. The current control of sheath blight is mainly to do fertilizer and water management, combined with pharmaceutical protection. And the long-term use of this single agent Jinggangmycin easily produce resistance, reduce the effect of prevention. In order to screen efficient and safe pesticides for control of rice sheath blight and provide basis for large-scale production and application, Yangzhong Plant Protection and Quarantine Station carried out the control of 17% Jinggang azoxystrobin rice sheath blight in August 2014.
