Abstract

 IMIDACLOPRID (1-[(6-CHLORO-3-PYRIDINYL) METHYL]-N-NITRO-2-IMIDAZOLIDINIMINE) IS A NEONICOTINOID INSECTICIDE THAT IS COMMONLY APPLIED AS A SYSTEMIC PESTICIDE FOR CONTROLLING MANY SPECIES OF SUCKING INSECT, TERMITES AND OTHER CHEWING PESTS. THIS IS HIGHLY PERSISTENT COMPOUND IN SOIL AND ACTS AS AN AGONIST ON THE POSTSYNAPTIC NICOTINIC ACETYLCHOLINE RECEPTORS (NACHR) CAUSING PARALYSIS AND DEATH IN INSECTS. SOIL BACTERIA HAVE AN IMPORTANT ROLE IN THE BREAKDOWN OF PESTICIDES IN THE ENVIRONMENT. THIS STUDY INVESTIGATED BIODEGRADATION OF IMIDACLOPRID IN MINIMAL SALT MEDIUM (MSM) BY RHIZOBIUM SP. FOR THE DURATION OF 25 DAYS. LEVELS OF IMIDACLOPRID IN MSM MEDIA WERE ANALYZED BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY (HPLC) WITH DIODE ARRAY DETECTION (DAD) AT 270 NM USING 40:60 (V/V) ACETONITRILE/WATER AS A MOBILE PHASE. RHIZOBIUM SP. WAS ABLE TO DEGRADE 45.48% OF THE INITIAL AMOUNT OF IMIDACLOPRID AT THE CONCENTRATION OF 25 MG/L IN C LIMITED MEDIA. THE SELECTED BACTERIUM WAS ISOLATED FROM VEGETABLE FARMS OF CAMERON HIGHLANDS IN MALAYSIA, WHICH HAD PREVIOUSLY BEEN EXPOSED TO DIFFERENT LEVELS OF IMIDACLOPRID. DEGRADATION ABILITY OF RHIZOBIUM SP. IN THIS STUDY WAS THE FIRST REPORT OF IMIDACLOPRID DEGRADING ISOLATE IN C LIMITED MEDIA FROM TROPICAL SOIL. THE RESULTS OF THIS STUDY DEMONSTRATE THE EFFECTIVENESS OF USING SOIL BACTERIA FOR MICROBIAL DEGRADATION OF IMIDACLOPRID.
