Abstract

AbstractNine insecticides were evaluated in lucerne for control of the lucerne flea, Sminthurus viridis. Carbaryl, chlorpyrifos, omethoate and isofenphos were the most effective. Each gave immediate control and the highest levels of persistence. Efficacy data of the insecticides against aphids, leafhoppers, earth mites and total numbers of predators are also given. Omethoate and chlorpyrifos were the most effective chemicals overall, although further information on their effects on the predator complex is required to support their recommendation. Carbaryl and fenvalerate showed promise for differentiating between damage by three major pests.
