INTERACTION BETWEEN SPRAY DISTRIBUTION AND SYSTEMIC ACTIVITY OF INSECTICIDES FOR CONTROL OF EUROPEAN CORN-BORER (LEPIDOPTERA, PYRALIDAE) IN PEPPERS AND SNAP BEANS

Interactions between spray distribution and insecticide mode of action in relation to control of Ostrinia nubilalis on bell peppers Capsicum annuum, sweet banana peppers Capsicum annuum and snap beans Phaseolus vulgaris were investigated. Spray deposition with the air-curtain sprayer was much higher on the undersides of the leaves and on fruit than with the conventional boom application. Acephate and fenvalerate significantly reduced banana pepper and bell pepper injury, but significant reductions in injury due to air-curtain application occurred only with fenvalerate on bell peppers. -from Authors
