Field Performance of Insecticides Treatments against the Immature and Adult Stages of Whitefly on Tomato Plant

Field experiments were carried out during 2015 and 2016 seasons at the experimental farm, Faculty of Agriculture, Saba-Basha, Alexandria University to evaluate the efficacy Prev-AM®, Planta® and Mospilan® against B. tabaci on tomato plants. prev-AM® achieved the highest initial and residual reduction% of whitefly adults giving (84.8%, 69.7%), respectively. Planta® achieved the highest initial and residual reduction% of whitefly immature giving (78.7%, 81.2%), respectively. On the other hand Mospilan® achieved the least initial effect. Sequence 4 (prev-AM®, Planta®) recorded the highest initial and residual reduction% of whitefly adult giving (86.3%, 83.1%), respectively. Sequence 5 (Planta®, Mospilan®) gave the highest initial and residual reduction% of whitefly immature giving (89.2%, 88.8%), respectively. Natural pesticides based on plant-essential oils may represent alternative crop protectants. From this study, orange oil and pyriproxyfen may introduce an effective control agents against whitefly in tomato field.
