Abstract

Abstract:

In order to clarify the control effect of flufenamide compound on whitefly and provide a theoretical basis for its production and application, relevant field efficacy tests were conducted in Hangzhou from July to September in 2022 with reference to the field efficacy test guidelines. The test showed that 24% avi fluridine SC 750-1 000 times mixed with 300-500 times of additives (wintergreen oil) could effectively control whiteflies (adults, nymphs, eggs) of eggplant and sweet potato. Under high insect population density, it is not recommended to use 22% fluorolidine and fluridine urea SC 750 times solution mixed with 300 times of additives to control sweet potato whitefly (adult, egg). The 24% avi fluridine SC mixed additive is an ideal treatment program for whitefly and has good application and promotion value.

Key words: flufenamide compound, whitefly, field control effect
