噻呋酰胺240k/L悬浮剂13mL/667m2、嘧菌酯250k/L悬浮剂40mL/667m2对水稻纹枯病病指防效分别为98.4%、97.0%,显著优于其它各药剂防效;丙环唑25%乳油45mL/667m2、己唑醇50%水分散粒剂10g/667m2病指防效分别为88.1%、84.9%;井冈霉素5%水剂200mL/667m2、咪鲜胺25%乳油80mL/667m2防效最差,分别为44.4%、37.0%。因此,噻呋酰胺、嘧菌酯对水稻纹枯病具有良好的预防及治疗效果,且对水稻生长安全,水稻纹枯病重发年份首选使用;丙环唑、己唑醇是取代井冈霉素的优良药剂,生产上可加以推广。
Thifluzamide 240k / L suspension 13mL / 667m2, azoxystrobin 250k / L suspension 40mL / 667m2 on rice sheath blight disease resistance were 98.4%, 97.0%, significantly better than the other agents control effect; C The control efficacy of the tetracycline 25% EC 45mL / 667m2 and hexaconazole 50% water dispersible granule 10g / 667m2 were 88.1%, 84.9%, respectively. The validamycin 5% water 200mL / 667m2 and prochloraz 25% EC 80mL / 667m2 the worst effect, respectively, 44.4%, 37.0%. Therefore, thifluzamide and azoxystrobin have good preventive and therapeutic effects on rice sheath blight, and are the first choice for the safe growth of rice and the year of re-emergence of rice sheath blight. Propiconazole and hexaconazole are substituted for validamycin Good medicine, can be promoted in production.
