Preliminary Study on Control of Chilo suppressalis by Nanopesticides
In recent years,the occurrence of Chilo suppressalis in rice production in Ningbo has been increasing year by year.In order to clarify the control effects of nanopesticides on Chilo suppressalis,a field efficacy trial was conducted during the appropriate period for controlling Chilo suppressalis,the traditional formulation and the nano-preparation of Emamectin Benzoate,Spinetoram and Methoxyfenozide,Spinetoram and Tetraniliprole were selected as experimental reagents.The results showed that after 14 days of pesticide application,the dry heart and insecticide control effect of Emamectin Benzoate(nano-preparation)were above 80%and 85%,respectively,and the yield retention effect was better,with a recovery loss rate of 44%to 45%.The pest control effects and recovery loss rate of nanopesticides were significantly higher than those of traditional formulations.
