Evaluation of the Microecological Regulatory and Control Effects of'GENKANG'on Soil Insects of Capsicum
To promote the green and efficient development of the Hainan capsicum industry,a targeted evaluation of the mi-croecological regulation and control effects of'GENKANG'on the soil insects of capsicum was conducted.The results re-vealed that,transplantation after roots soaking in 1 000-fold and 1 500-fold of 20%'GENKANG'microemulsion for 10 min-utes and 30 and 45 kg·hm-2 of 20%'GENKANG'controlled release formula in furrows were the best to microecological regu-late and control soil insects of capsicum,the damage rates of soil insects of capsicum transplanted for 5-30 days were below 5%,respectively;transplantation after roots soaking in 2 000-fold of 20%'GENKANG'microemulsion and 15 kg·hm-2 of'GENKANG'controlled release formula in furrows were also better to microecological regulate and control soil insects of capsicum,the damage rates of soil insects of capsicum transplanted for 5-30 days were below 10%,respectively;500-fold of 20%'GENKANG'microemulsion was also better to microecological regulate and control soil insects,but the treated seeds and plants could not normally develop;transplantation after roots soaking in 2 500-fold and 3 000-fold for 10 minutes and 3.75 and 7.5 kg·hm-2 of'GENKANG'controlled release formula in furrows were not efficacious to soil insects,while they were safe to the developments of seeds and plants.Given the economic effects and simple operation,transplantation after roots soaking in 1 500-fold of 20%'GENKANG'microemulsion for 10 minutes and 30 kg·hm-2 of 20%'GENKANG'controlled release formula in furrows can be widely applied to microecological regulation and control soil insects of capsicum.
