为了筛选防治稻瘟病菌的高效新型杀菌剂,对75%肟菌酯.戊唑醇水分散粒剂及对照药剂40%富士一号乳油和20%三环唑可湿性粉剂进行了室内毒力测定,并对其进行了田间药效防治试验。结果表明:75%肟菌酯.戊唑醇水分散粒剂、40%富士一号乳油和20%三环唑可湿性粉剂的EC50分别为8.00 mg/L、8.79 mg/L和60.68 mg/L。75%肟菌酯.戊唑醇水分散粒剂防治水稻叶瘟的3个处理浓度10g/667m2、15g/667m2和20g/667m2的防效分别为75.58%、83.07%和87.54%,对照药剂40%富士一号乳油120 mL/667m2和20%三环唑可湿性粉剂100g/667m2的防效分别为72.15%和75.69%。75%肟菌酯.戊唑醇水分散粒剂可作为防治稻瘟病(叶瘟)的药剂在生产上与其他药剂交替使用。
In order to screen for a new and highly effective fungicide for controlling Magnaporthe grisea, indoor toxicity assay was carried out on 75% trifloxystrobin, tebuconazole water dispersible granule and 40% Fuji-1 emulsifiable concentrate and 20% tricyclazole WP , And conducted its field efficacy test. The results showed that the EC50s of 75% trifloxystrobin, tebuconazole water dispersible granules, 40% Fuji I EC and 20% tricyclazole WP were 8.00 mg / L, 8.79 mg / L and 60.68 mg / L respectively . 75% Trifloxystrobin. The control effects of tebuconazole water dispersible granules against rice leaf plague were 75.58%, 83.07% and 87.54% for the three treatment concentrations of 10g / 667m2, 15g / 667m2 and 20g / 667m2, respectively. The control effects of% Fuji-1 EC 120 mL / 667m2 and 20% tricyclazole WP 100g / 667m2 were 72.15% and 75.69%, respectively. 75% Triclosan Tebuconazole Water dispersible granules can be used as a medicament for the control of rice blast (leaf plague) in the production of alternating with other agents.
