Annamalai University, Annamali Nagar.
A field experiment was carried out to evaluate different Dipel (a bacterial formulation - Bacillus thuringiensis var alesti Berliner) organic insecticide combinations against mosaic virus and brinjal little leaf diseases as they are prevalent in this part of the country. It was found that Sevin + Dipel was superior for brinjal mosaic virus and Thiodan and Ekalux + Dipel (alternate day sprays) for little leaf. The chemicals caused a decline in the respective vector populations effectively.
