Management of Childers canegrubs, Antitrogus parvulus Britton, is heavily dependant on organophosphate insecticides. As part of a programme to develop and integrate a wider spectrum of controls, we tested the potential of imidacloprid to control existing infestations of third-instar larvae in sugarcane. Two SC and one WG formulation of imidacloprid (Confidor ( R)) were tested in 11 trials...
