摘要
展膜油剂是一种专为省力化施药研制的农药剂型。为明确新药剂4%嘧菌酯·噻呋酰胺展膜油剂对水稻纹枯病的防治效果,分别在河北省、湖北省、湖南省及上海市选取8地进行了2年田间药效试验,比较了不同剂量处理间的防治效果。结果表明,4%嘧菌酯·噻呋酰胺展膜油剂对水稻纹枯病具有较好防效,优于对照药剂25%嘧菌酯悬浮剂及240g/L噻呋酰胺悬浮剂防治效果,且使用方便。当施药量达到200mL/7667m^2时,2014年,在河北省、湖北省、湖南省及上海市,药后14d防效分别为82.41%、89.2%、83.25%及95.29%;2015年,在河北省、湖北省、湖南省试验地,药后14d防效分别为81.72%、81.95%、90.9%;两年防效均优于或持平于对照药剂。最佳施药量为200mL/667m^2.
The spreading oil is a pesticide formulation specially developed for labor-saving application.To determine the control efficacy of azoxystrobin+thifluzamide 4%spreading oil against rice sheath blight,field efficacy trials were conducted in 8 sites located differently in Hebei,Hubei,Hunan and Shanghai during 2014 and 2015.The results showed that azoxystrobin+thifluzamide 4%spreading oil was convenient for application and was able to control rice sheath blight effectively.Compared with azoxystrobin 25%SC and thifluzamide 240g/L SC,azoxystrobin+thifluzamide 4%spreading oil had best control efficacy.In 2014,after 14 days of application in Hebei,Hubei,Hunan and Shanghai,the control effects of azoxystrobin+thifluzamide 4%spreading oil were 82.41%,89.2%,83.25%and 95.29%,respectively.In 2015,the same experiments were conducted in Hebei,Hubei and Hunan,the control effects were 81.72%,81.95%and 90.9%,respectively.In years,azoxystrobin+thifluzamide 4%spreading oil provided better or equal control efficacy compared to the control agent.The optimum application dose was recommended as 200mL/667 m^2.
