COMPARATIVE IMPACT OF PHORATE AND CARTAP ON BIOMOLECULES OF E. fetida
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 16
Abstract
The study of 60 days was carried out to analyze the effects of pesticides viz. cartap and phorate on the biomolecules i.e. carbohydrate, lipid and protein content of Eisenia fetida. The earthworms were exposed to cartap (1.0, 1.5 and 2.0 mg/Kg), phorate (1.0, 1.5 and 2.0 mg/kg) and cartap + phorate (0.5 + 0.5, 0.75 + 0.75 and 1.0 + 1.0 mg/kg). The samples of E. fetida were collected on first day and 60th day of pesticide exposure. Significant reduction in the carbohydrate, protein and lipid contents as compared to control has been recorded on the final day of study. Maximum reduction in biomolecules i.e. 6.949% protein, 27.632% lipid and 2.000% carbohydrates was observed with Cartap (2.0 mg/kg) followed by 6.237% protein, 25.981% lipid and 1.410% carbohydrates in Phorate + Cartap (1.0 + 1.0 mg/kg). Among the two insecticides (Phorate and Cartap) under investigation, Cartap was found to have more toxic effects when used alone as well as in combination with Phorate.
