Efficacy of horticultural mineral oil and its combinations against leafhopper Amrasca biguttula biguttula (Ishida) in brinjal and whitefly Aleurodicus dispersus Russell in chilli, Kerala, India

Abstract

Horticultural mineral oils (HMO) and its combinations were evaluated against leafhopper Amrasca biguttula biguttula (Ishida) in brinjal and whitefly Aleurodicus dispersus Russell in chilli. HMO (3%) in combination with thiamethoxam (25WG 0.1g L-1), was significantly effective in control the leaf hopper on brinjal. While in the case of white fly on chilli HMO (3%) with thiomethoxam (25WG 0.2g l^-1) was effective. The results show a reduction in pesticide load to half without compromising pesticide efficacy.
