Abstract | ||||
Insecticides rotation strategy was applied after treatment of the seedlings of tomato variety Rover (E-446) F1 hybrid in the nursery using thiamethoxam and imidacloprid (foliar and drench application) for the control of Bemisia Tabaci. Twelve treatments with biorational and conventional insecticides in a rotation programs was applied at Syngenta Kaha Station, Kalubia Governorate, Egypt. The best treatment was seedlings treated with thiamethoxam at 30g/20000 seedlings as drench application in the nursery and a sequence of thiamethoxam, twice fenpropathrin, and twice pymetrozine in open field. It gave good results for controlling the adults stage of B. tabaci and minimized the number of infected plants and percent surface area showing virus symptoms. Also, the highest yield of tomato was obtained after five sprays during the season. The present study suggests that drench application in the nursery was a good treatment in reducing and delaying attacks by B. tabaci. | ||||
