Indoor Control Efficacy of Four Seed Coating Treatments Against Three Common Pests of Cowpea Seedlings
摘要
Abstract
Cowpea aphids,two-spotted spider mites,and bean thrips are main pests during the cowpea seedling stage,severely impacting the growth and development of cowpea plants.To evaluate the safety and control efficacy of four seed coating treatments,10％clothianidin flowable concentrate for seed treatment FS,30％thiamethoxan FS,600 g/L imidacloprid flowable concentrate for seed coating FSC and 8％fipronil FSC on three common pests during the cowpea seedling stage,this study conducted indoor pot experiments with insect infestations.The experiments aimed to evaluate the impact of the four seed coatings on cowpea emergence and the effectiveness in controlling cowpea aphids,two-spotted spider mites,and bean thrips.The results indicated that the germination rate of cowpea treated with 10％clothianidin FS,30％thiamethoxan FS,600 g/L imidacloprid FSC,and 8％fipronil FSC was 95.83％,91.67％,95.83％and 95.83％,respectively.The rate was slightly lower than that of the control(100％),but did not significantly affect crop growth.The findings revealed that 30％thiamethoxan FS exhibited the highest control efficacy against both cow-pea aphids and bean thrips.Specifically,the control efficacy against cowpea aphids at 3,7 and 14 days post-infestation was 65.04％,81.10％and 72.35％,respectively.For bean thrips,the control efficacy at the same time points was 15.41％,58.61％and 54.89％,respectively.As the infestation period progressed,the effectiveness of the seed coating treatments in controlling cowpea aphids and bean thrips gradually decreased.None of the four seed coating treatments demon-strated significant control efficacy against two-spotted spider mites.This research provides technical support for pest management during the seedling stage of cowpea production.关键词
