30%爱苗EC防治水稻稻瘟病田间药效研究

Study on Field Efficacy of 30% Armure EC Against Rice Blast

[目的]验证30%爱苗EC对稻瘟病的防治效果。[方法]以优优128为供试水稻品种,在广东潮安县水稻种植区对该药剂进行了小区药效试验。[结果]施药后各药剂均未对水稻产生明显药害。30%爱苗EC 225 mL/hm2对水稻稻瘟病的防效达85.00%,30%爱苗EC 225mL/hm2与45%硫.三环唑WP 2.1 kg/hm2混合施用对水稻稻瘟病的防效可达99.16%。[结论]30%爱苗EC及混合药剂是防治水稻稻瘟病的特效药剂。

[Objective] The aim was to validate the control efficiency of 30% Armure EC against rice blast.[Method] With Youyou128 as tested material,the controlling test with 30% Armure EC was carried out at the zone that the rice blast occurred often in Chaoan county,Guangdong province.[Result] No obvious phytotoxicity was observed after bactericide application.The control efficacy of 225 mL/hm2 30% Armure EC was 85.00%.The control efficacy of mixed application of 225 mL/hm2 30% Armure EC and 2.1 kg/hm2 45% sulphur·tricyclazole was 99.16%.[Conclusion] 30% Armure EC and its mixture were regents with special effects against rice blast.
