[Objective] The research aimed to understand the application effect of 17.2% pyraclostrobin · epoxiconazole suspen-sion in controlling corn leaf spot. [Method] The control effect of 17.2% pyraclostrobin-epoxiconazole suspen-tration emulsions on corn leaf spot and their health effects on corn plants were studied in the field experiment of two years in 2012 and 2013. [Result] The control effect of 17.2% pyraclostrobin and epoxiconazole suspension on maize leaf blotch disease was more than 90%. The spike length of maize was significantly increased after treated with the agent, the chlorophyll content increased, the percentage of baldness decreased and the yield increased . [Conclusion] 17.2% pyraclostrobin · epoxiconazole suspension had a good control effect on maculopathy and had the effect of improving yield of corn.
