Summary of effectiveness of Lambda-cyhalothrin for control of sugarcane stemborers; preparedness for borer incursion

Abstract

Following a search of the literature, lambda-cyhalothrin (Karate 2.5EC) was identified as a potential candidate insecticide for emergency use in Australia following an incursion of a stemborer.Lambda-cyhalothrin is a stomach and contact pyrethroid used to control a wide range of pests. The insecticide (as Karate?) is registered against Sesamia grisescens in Papua New Guinea and Eldana saccharina in South Africa. It is also used against Busseola fusca in Ethiopia, Chilo partellus in Pakistan, and Ostrinia nubilalis in Poland.Lambda-cyhalothrin is an essential management component that fits well within an overall Integrated Pest Management program for stemborer pests. Data on its chemical structure and physiochemical properties are presented in this report.
