Abstract:

Imidacloprid is used extensively in mango ecosystem to control hopper. It can persist in soil as residues for around 150 days. Many soil microorganisms have the ability to degenerate many pesticides by converting them to non-toxic compounds. The present study was undertaken to isolate imidacloprid degrading microbe from mango orchard soil and to test its utility in field conditions. Among the four isolated bacteria, Pseudomonas mosselii strain NG1 was found most effective in degrading imidacloprid. After spraying imidacloprid at 0.005% in mango trees, soil samples were treated with Pseudomonas mosselii strain NG1 immobilized in straw and as free form in broth. Immobilized P. mosselii degraded imidacloprid faster (from 0.606 µg g–1 in 0 day to 0.052 µg g–1 after 67 days of treatment – 91.42% degradation) in soil as compared to P. mosselii in free form (from 0.30 µg g–1 in 0 day to 0.043 µg g–1 after 67 days of treatment – 85.67% degradation) and control (from 0.216 µg g–1 in 0 day to 0.048 µg g–1 after 67 days of treatment – 77.78% degradation). The half-life values were calculated as 24.0, 15.5 and 8.0 days in soil without bacterial application, with P. mosselii in free form and with P. mosselii in straw, respectively. In conclusion, immobilized P. mosselii strain NG1 can be used to degrade imidacloprid in mango orchard soil. This is the first report of P. mosselii strain NG1 having imidacloprid degradation potential.
