- •
Continuous application of chlorpyrifos on soil microbes and nematodes were studied.
- •
Chlorpyrifos at field dose to rice soil was not harmful to most of the soil microbes.
- •
Nitrogen mineralization microbial groups were most sensitive to chlorpyrifos.
- •
Plant-parasitic nematodes showed variable response to chlorpyrifos treatment.
- •
Half life of chlorpyrifos residue was found to be 4.02 days in rice soil.
