Abstract
The field efficacy of four plant extracts such as Vitex negundo L. (Verbenaceae), Clerodendrum inerme (L.) Gaertn. (Verbenaceae), Lantana camara L. (Verbenaceae) and Eupatorium odoratum L. (Asteraceae) were evaluated against the diamondback moth, Plutella xylostella L. and the cotton bollworm, Helicoverpa armigera Hub. larvae on cultivated cabbage. Treatments with 1% V. negundo and C. inerme extracts significantly reduced P. xylostella larval density, and the percentage of infested plants, proving to be more effective than a standard insecticide Challenger 10EC (cypermethrin). Treatment with L. camara extract (1%) reduced the percentage of H. armigera infested plants and the intensity of cabbage damage. However, the plant extracts did not effectively reduce H. armigera larval density, and cabbage damage. Phytotoxic effects on cabbage plants were not observed in any extract treatment. Two plant extracts, V. negundo and C. inerme at 1% significantly reduced the P. xylostella larval density and proved more effective than Challenger. The intensity of cabbage damaged caused by P. xylostella was significantly lower in L. camara and C. inerme than control and Challenger.
