Studies the Effects of Imidacloprid on Enzymatic Activities in Clay Loam Soil

In-vivo experiment was conducted for toxicity evaluation of Imidacloprid on soil enzyme activities arylsulphatase, acid-phosphatase and dehydrogenase activities in the treated soil under control condition for 60 days at different application rate 3.97µg mL FR , 7.94µg mL 2FR and 39.7µg mL 10FR . Imidacloprid has significant toxic at 2FR and 10FR doses but not on the recommended field rate FR . Acid phosphatase activity was stimulated at FR rate, whereas at higher dose 10FR inhibited the activity. A significant drop of dehydrogenase activity was observed irrespective of doses at 30 days of application and after that the enzymatic activity slowly increased. Application of Imidacloprid at FR to agriculture soil of Tripura is not likely to show any detrimental effects on soil acid phosphatase and dehydrogenase activities but at higher elevated doses there appear some harmful effects which was also very much transient.
