Abstract: 【Objective】 Study on Carposinasasakii Matsmur and screen out the environmentally friendly pesticides and application amounts in the hope of providing scientific basis for effectively controlling the occurrence and harm of Carposinasasakii Matsmur. 【Methods】 To clarify the control effect of 10 new insecticides.In 2022, field community efficacy tests were carried out to compare the control effects of different insecticides. 【Results】 The prevention effect of 10 pesticide treatment pesticides was good for 7 days, and there was no significant difference between treatments (P>0.05), among which 10% biphenyl fluranyl urea suspension, 1% matrine solution and 12% methyl carboxynitrile suspension were more than 93.33% after 14 days after the recommended dilution factor, and the prevention effect of 1% matrine solution in all treatment areas was more than 90.00% 21 days after applying pesticides, and the prevention and control effect fluctuated between different agents in 14-21 days after the drug. 【Conclusion】 The treatments of 10 agents on Carposinasasakii Matsmur have significant control effects on Carposinasasakii Matsmur for 7 days after the trial, including 1% matrine solution, 10% biphenyl fluranyl urea suspension and 12% carboxylapyril suspension, which all have excellent control effect for 14 days after application, and are recommended for use in production practice.
