Abstract

The effect of encapsulated formulation of six insecticides viz., aldicarb sulfone, bendiocarb carboturan, isofenphos, orthene, and methomyl, was evaluated by applying in the leaf axils of banana against banana aphid The encapsulated formulation were prepared by filling the two-piece gelatin capsules with soluble or wettable powders of insecticides. All insecticides ex- cept bendiocarb were found to be effective in controlling the aphids. The herbicide capsule, pre- pared by filling with 2,4-D wettable powder., was found to be effective in destroying the diseased plants, when implanted into the pseudostem of the plant. A simple applicator, "Capsule dropper". to place the capsules in the leaf axils of grown up plants and a hand unit for preparing encapsulated formulation were designed.
