摘　　要：[Objective]The paper was to study the field control effects of different formulae of plant extracts against cabbage worm Pieris rapae,and to provide a basis for promotion and application of insecticides in production.[Method]With the leaching solution of radix anemones rivularis,Artemisia carvifolia and Nicotiana rustica,and lime and salt water as the materials,field efficacy test was conducted for consecutive two years.[Method]When the mass ratios of radix anemones rivularis mother liquid,A.carvifolia mother liquid,N.rustica mother liquid,lime water and salt water were 4:2:2:1:1:6,4:2:0:1:1:8,4:0:2:1:1:8 and 0:4:2:1:1:8,the control effects were 82.7%-89.8%,38.3%-42.0%,41.0%-45.4%and 52.9%-56.4%,respectively.The insecticide showed the best control effect when the mass ratio of radix anemones rivularis mother liquid,A.carvifolia mother liquid,N.rustica mother liquid,lime water and salt water was 4:2:2:1:1:6.[Conclusion]The optimal formula has good control effect against P.rapae,and the technology has obtained national invention patent.[Objective] The paper was to study the field control effects of different formulae of plant extracts against cabbage worm Pieris rapae, and to provide a basis for promotion and application of insecticides in production.
