Effects of Synthetic Pyrethroids on Phosphate Solubilizing Activity of Microorganisms

Pesticides are the important agrochemicals used for prevention of crops from pests. Their use has been largely increased in last few decades. The application of pesticides starts from the pre sowing stage. Different treatments include soil application, seed treatment, foliar spray, etc. Repeated applications of pesticides contaminate the soil. Soil is the most important site of biological interactions. The indiscriminate use of pesticides disturbs the soil environment by affecting flora and fauna including microflora of soil, and also the physicochemical properties of soil like pH, salinity, alkalinity leading to infertility of soil (Sarnaik et al., 2006).
