Abstract: Phytotoxicity is defined as the detrimental effect of chemical products used for the eliminating or growth regulating purpose on some morphological, anatomical and physiological processes of plants. We examined the effect of chlorpyrifos, which is used to crop against fleas, insects, termites, pests and mosquitoes to determine whether it adversely affect ashwagandha plant. 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 ie., 30, 45 and 60 days after transplanting on ashwagandha. The biochemical characteristics of ashwagandha were recorded after various doses of pesticide treatment application. The peroxidase and catalase activity decreased with increasing level of pesticide treatment in ashwagandha. Chlorophyll a content and chlorophyll b content decreased with higher dose of pesticide treatment in the experimental crops.
