SUMMARY
Improper pesticides application can cause serious damages to the environment. In this study, the impact of organophosphorus insecticide (chlorpyrifos) on the soil bacterial composition was investigated. Pseudomonas sp. and Staphylococcus sp. were inhibited by CP but favoured the growth of Bacillus sp. The highest species diversity was observed on Day 0 subsequent to the pesticide application and this resulted in significant abundance and composition of soil bacterial diversity. Furthermore, the genera Bacillus was identified as the genera with highest resistance to chlorpyrifos toxic compounds and possible bacterial isolate for contaminant removal from the soil microcosms. These results could be helpful in strategy selection and monitoring of the environmental remediation approaches, ensuring continuous effective, productive and sustainable agricultural practices, and the long-term well-being of the environment. There is a dire need to balance pest control and environmental protection and this can be achieved by promoting sustainable agricultural practices; employ integrated pest management, follow recommended dosage rates, create protective buffer zones around water bodies and sensitive habitats to prevent contamination, train farmers and agricultural workers on proper pesticide handling, storage and disposal, and enforce local, state and federal regulations on pesticide management.
