Insecticide Microflora Interactions in Banana Rhizosphere

A field trial was conducted to study the impact of different insecticides recommended for the Control of pests of banana on different soil flora (Fungi, Bacteria and Actinomycetes) in the soil. The samples were drawn at monthly intervals till harvest of the crop. In carbaryl treatment, microbial population was low initially, but got restored later. With carbofuran, slight reduction of microbial population was observed immediately after the application of insecticides and got restored before harvest. But, with phorate, a slight enhancement of the population of bacteria and fungi was observed after the application of insecticides and it was restore at par with control before harvest of the crop.
