Description
Summary:Systems of chemical control were implemented in a plastic greenhouse to control mainly Frankliniella occidentalis (Pergande) in eggplant with several effective eligible groups of insecticides, spraying insecticide singly with new mode of action or in sequence with conventional. The system consisted of three phase of strategy to cope with initial population build up, sporadic pests and F. occidentalis population control. To check the effectiveness of the control system it was evaluated phytotoxicity, the residual toxicity, spraying frequency, insecticidal spectrum against Tetranychus urticae Koch, and Liriomyza trifolii (Burgess), and marketable quality and yield. Spraying singly with abamectin or imidacloprid gave high yields with low damage to the eggfruits. Furthermore abamectin 1.8 emulsifiable concentrate (Ec) showed wide range of insecticidal activity against T. urticae and L. trifolii with slightly less spraying frequency.
