Study aim to evaluate the effect of chlorpyrifos on several metabolic and stress related parameters associated with pesticide resistance. The experiment was conducted at Indian Institute of Soil Science (ICAR), Bhopal (MP) during 2015-2016, comprising four concentrations of pesticide chlorpyrifos viz. 0%, 0.25%, 0.75% and 1.25%. The commencement of foliar treatment applied on vegetative phase i.e., 30, 45 and 60 days after sowing on soybean (Kharif) and wheat (rabi). The morphological, physiological and biochemical characteristics of soybean and wheat were recorded after various doses of pesticide treatment application. It was observed that the increased rate of pesticide treatment significantly decreased the morphological parameters i.e., plant height, number of leaves, leaf area leaf dry weight, stem dry weight, root dry weight. The rate of photosynthesis, transpiration, stomatal conductance decreased with increased concentration of pesticide in soybean and wheat. The peroxidase, polyphenol oxidase activity and structural carbohydrate decreased with increasing level of pesticide treatment in both the experimental crops. Whereas, nitrate reductase, soluble protein and proline content increased with increasing levels of pesticide treatments. However, the increase in soluble protein and protein content was more in wheat as compared to soybean and also shown more resistance towards the oxidative stress.
