Evaluation of Control Efficiency of Insecticides Against Bemisia tabaci of Facility Tomato
To screen the highly control insecticides against Bemisia tabaci of facility tomato,six insecticides were selected to test by spraying method in this study,and the control efficiency of different insecticides against Bemisia tabaci and yield of tomato were investigated and compared.The results showed that all the insecticides had the inhibitory effects against Bemisia tabaci,among which 22.4%spirotetramat SC and 22%sulfoxaflor SC exhibited the better control efficiency.After 7 days of application,their control efficiency exceeded 84%,which was 30%higher than the yield of CK.These two insecticides had no adverse impacts on crops and environment,which were suggested to be used alternately in production to achieve effective prevention and control purposes.
