Abstract

In order to explore the safety of maize growth,the new fungicide can effectively prevent and control maize northern leaf blight.The safety of prothioconazole and its compound preparation was studied in field plots.The results showed that,Prothioconazole 250 DC,67.5%sulfur·prothioconazole SC,and prothioconazole.azoxystrobin 360 SC were safe for maize growth in the test dose range,and it has the effect of enhancing maize growth,the yield increase rate reached 10.0%-12.5%;Spray at the initial stage of maize northern leaf blight,effect ranged in 80%to 100%,and long validity period.Recommended to use prothioconazole 250 DC dose 32.0-37.3mL·(667 m2)-1,67.5%sulfur·prothioconazole SC dose 133.3-186.7 mL·(667 m2)-1,prothioconazole.azoxystrobin 360 SC dose 33.3-46.7 mL·(667 m2)-1 prevention of maize northern leaf bligh,high amount of susceptible varieties or plots with severe disease in the previous year,note the use of the agent in rotation.
