摘要
田间试验表明,参试农药68.75%银法利SC800倍液、1000倍液、1500倍液和甲霜灵·锰锌800倍液对石斛疫病均有防效,其中银法利800倍液在病害初期3次施药后防效最高,可达85.32%,与同药剂1000倍液处理呈显著差异,但两者都极显著优于银法利1500倍液和甲霜灵·锰锌处理。
The results from field trial showed that tested Infinito SC（68.75% fluopicolide prompamocarb hydrochloride）in dilute with water at 800,1,000 and 1,500 folds,respectively,and control chemical metalaxyl-mancozeb in dilution of 800 have the effect against Dendrobium devonianum blight.The highest control effect（85.32%） can be obtained while applied 3 times with Infinito SC at 800 at the very beginning of disease.
