Efficacy of Difenoconazole Emulsifiable Concentrate with Ionic Liquids against Cucumbers Powdery Mildew

摘要

Among eight ionic liquids (ILs) examined, 1-n-butyl-4-methyl-pyridinium bromide (BMPyBr,? 5) was used in this study as an appropriate alternative to benzene homologs and derivatives to be used in 10?wt% water-insoluble difenoconazole emulsifiable concentrate (EC). Moreover, 10?wt% difenoconazole EC with BMPyBr (5) exhibited the same efficacy as 10?wt% difenoconazole wettable powder (WP) against powdery mildew on cucumbers under field conditions. The results revealed that difenoconazole EC with BMPyBr (5) had excellent stability at 268?K and 327?K after 14 days through high-performance liquid chromatography (HPLC). Therefore, ILs can be considered as promising environment-friendly adjuvants for pesticides that are commercially processed as EC formulation.
