Abstract:

Field and laboratory experiments were conducted to investigate twelve insecticides comprising granular and spray formulations of imidacloprid, cartap hydrochloride, fipronil, chlorantraniliprole along with carbofuran, phorate and monocrotophos as insecticidal checks for their effects on soil dehydrogenase activity in rice ecosystem during kharif 2015. Sprayable and granular insecticidal applications at 20 and 50 DAT demonstrated that granules in general showed a greater negative effect on soil microbial activity compared to their spray counterpart. Both the formulations of chlorantraniliprole and cartap with greater dehydrogenase activity of 395-479 and 340- 675 µ g TPF/g soil respectively consistently favoured the microbial activity at 10 and 20 days after insecticidal application as compared to other test molecules. Carbofuran 3G was found to be the safest granule showing greater phytotonic effect to plants.
