A field experiment with carbofuran 25 SD as seed treatment followed soil application of sebuphos 10 G or carbofuran 3G, 30 days after sowing, was conducted for the control of Kalahasti malady. Maximum reduction in nematode population, disease severity and increase in pod yields were obtained in sebuphos 10 G and carbofran 3G soil treatments at 4 kg a.i./ha JL-24 groundnut seed treatment with carbofuran 25 ST at 2% followed by soil application of sebuphos 10 G at 3.25 kg a.i./ha was next best with significant decrease in nematode population and disease severity and increase in pod yield. It was at par with the soil treatments of sebuphos 10G and carbofuran 3G at 4kg a.i./ha each. Hence, it can be recommended to the farmers for the control of the disease.
