Agriculture is important for food production, and adverse effects on agriculture are directly linked to human health. Several types of chemical pesticides are used to control agricultural pests to increase agricultural productivity. These pesticides have a deleterious effect on several plant processes, thereby affecting plant growth. By altering soil enzyme activity, these pesticides affect not only plant development but also soil health. Three pesticides (insecticides) that are frequently used in agriculture, cypermethrin, phorate, and malathion, were used in our experiment, and their field-recommended dosages were used. We investigated the impact of these pesticides on plant growth and soil enzyme activities. Plant growth parameters such as root length, shoot length, number of leaves, root collar diameter, total branches, and total phenolic content (TPC), chlorophyll content, and reducing sugars were also assessed using the host mung bean (Vigna radiata L.). Soil enzymes, including invertase, acid phosphatase, alkaline phosphatase, urease, cellulase, and protease, were used to detect the impact of pesticides on soil health. The most negative impacts on plant growth parameters were observed in malathion-based treatments. Malathion and phorate were the most affecting pesticides on soil enzymes.
