The performance of palm-based emulsions in water (EW)-insecticide formulations was evaluated in the field against insect pests on chilli and brinjal crops. The insecticides used were deltamethrin and lambda-cyhalothrin. Phytotoxicity symptoms were also evaluated on the treated crops. The untreated plots gave the highest number of damaged fruits in chilli and brinjal when compared to the treated plots. In addition, no phytotoxicity symptom was observed in both the brinjal and chilli crops, meaning that they showed good tolerance to all the treatments. Statistical analyses (using Duncan’s multiple range test at the probability, P, of less than 0.05) of the differences between treatments indicated that the palm EW-pyrethroid insecticide formulations were equally effective or significantly better than the commercial emulsifiable concentrates (EC) formulations at the recommended (10 ml/10 litres) and lower (7.5 ml/10 litres) doses in controlling the pests on chilli and brinjal crops. The residues of the EW-pyrethroid insecticides on the crops were also determined.
