Fate of Methomyl on Cotton 1

Foliar treatments with methomyl appear to be promising (Coppedge et al. 1972, McGarr et al. 1972) as a method of controlling certain lepidopteran pests of cotton including the bollworm, Heliothis zea (Boddie), and even the tobacco budworm, Heliothis virescens (F.). This latter insect pest has become increasingly difficult to manage in certain areas due to the development of resistance to organophosphorus and other insecticides (Adkisson 1969).
