为延缓稻纵卷叶螟抗药性的产生和发展,采用8种不同药剂防治稻纵卷叶螟进行田间药效试验。结果表明,36%氰虫·毒死蜱悬乳剂、24%甲氧虫酰肼悬浮剂、20%氯虫苯甲酰胺悬浮剂、20%甲维·茚虫威悬浮剂、12%甲维·氟酰胺微乳剂、10%阿维·氟酰胺悬浮剂、10%阿维·甲氧虫酰肼悬浮剂对稻纵卷叶螟防效均较理想,药后14 d防效幅度在90.2%~98.2%;33%阿维·抑食肼可湿性粉剂持效性稍差,药后14 d防效85.3%。
In order to delay the emergence and development of rice leaf roller resistance, 8 different medicaments were used to control the rice leaf roller. The results showed that 36% cypermethrin · chlorpyrifos suspoemulsion, 24% methoxyfenozide suspending agent, 20% chloramphenicol suspending agent, 20% carbaryl indoxacarb suspension, 12% The control effect of microemulsion, 10% Avrilitamide and 10% Avicel suspension on rice leaf roller is ideal, and the control effect is 90.2% -98.2% after 14 days. ; 33% Avicad’s hydrazone wettable powder was somewhat less effective, with a defensive effect of 85.3% on the 14th day after treatment.
