Abstract
A supervised field experiment was conducted in the chilli during Rabi, 2014-15 to study the impact of certain biopesticides in leaf curl disease and its vectors viz., thrips and mites. The treatments were application of Nanma @ 1 per cent (T1), application of neem oil 0.15EC @ 0.3 per cent (T2), application of Sonata @ 0.1 per cent (T3), alternate spray of T1, T2 and T3 (T4) and untreated check (T5). It was found that thrips and mites population was higher in untreated check (0.80 and 1.39, respectively) while a low population was recorded in the treatment with the alternate spray of T1, T2 and T3 (0.10 and 0.16, respectively). Similarly lowest leaf curl index was recorded in alternate spray of T1, T2 and T3 (T4) (0.20) followed by application of neem oil 0.15EC @ 0.3 per cent (T2) (0.21). It can be concluded that alternate spray of nanma @ 1 per cent, neem oil 0.15 EC @ 0.3 per cent, sonata @ 0.1 per cent can reduce leaf curl disease incidence in chilli.
