A number of leaf-eating lepidopteran pests, such as Spodoptera litura, diamondback moth (Plutella xylostella), Crocidolomia binotalis, and others are serious pests of cabbage in Bangladesh. Indiscriminate applications of poisonous pesticides by the farmers to control the pests have complicated the safety issues of the environment and health of the consumers. This project used an IPM package involving mechanical control and use of biocides,which can significantly reduce pesticide usage facilitating the production of cabbage safer for consumers and the environment.
To minimize the infestation of leaf-eating lepidopteran pests and produce relatively pesticide-free cabbage crops by adopting an IPM approach.
The results have shown that production of healthy, pesticide-free cabbage is possible through utilizing IPM practices, such as destruction of pest larvae by handpicking. This measure is more profitable than applying pesticides, which is normally practiced by the farmers.
