Control trials against the rough brown weevil Leptopius corrugatus Pascoe

Abstract

Seventeen insecticides were tested in field trials against adults of the rough brown weevil Leptopius corrugatus Pasc. (Coleoptera:Curculionidae), a pest of tropical pasture legumes. In these trials the more efficacious materials were azinphos-ethyl, dieldrin and methidathion each at a spray strength of 0.05% active constituent.
