Abstract
Pesticides are recognized for disrupting the biochemical processes of plants, consequently reducing their food quality. An experiment was carried out at the main agriculture research field of Lovely Professional University in Punjab, India, to examine the effects of various insecticides on brinjal yield and the evaluation of the residual levels of different pesticides in brinjal, along with their influence on the biochemical properties of brinjal. The experiment comprises nine treatments arranged in a completely randomized block design with three replications. The quantification of pesticide residues in brinjal was evaluated using high-performance liquid chromatography (HPLC). The data analysis showed that T7 (Cartap- hydrochloride 50% SP) exhibited the highest yield parameters, including the number of fruits per plant (7.00), fruit length (14.20 cm), fruit width (7.96 cm), fruit yield per plant (0.98 kg), fruit yield per plot (29.44 kg) and fruit yield (36.35 t ha-1) as compared to T0 (control). The residual analysis results indicated that insecticide residues decreased below the detection limit (BDL) on the following days: the seventh day for acetamiprid, deltamethrin, and cartap hydrochloride; the tenth day for triazophos and chlorpyrifos; and the fifteenth day for carbofuran, with residual levels ranging from 0.034 – 1.391 mg/kg for various insecticides. No residues were detected in botanical insecticides and the control treatment. The biochemical parameters of brinjal fruit exhibited negligible and insignificant variation among different treatments when compared to the control. The results concluded that the influence of pesticide residues on biochemical properties was negligible when applied at recommended dosages.
