Control of root-lesion nematode, Pratylenchus coffeae in certain cultivars of banana using different chemicals

An experiment was conducted in the field heavily infested with root-lesion nematode on three commercial cultivars of banana viz., Karpuravalli (ABB), Monthan (ABB) and Nendran (AAB) by using two nematicides viz., Monocrotophos and Carbofuran in different doses at different period of application along with the recommended practice of paring and pralinage of the suckers. Both the chemicals were found to be effective in reducing the nematode population and subseqcently increase the plant growth and yield when compared to untreated control. The treatment combination of suckel dip with mud slurry and sprinkle with carbofuran @ 50 g/sucker followed by two applications after planting at 3 monthly intervals was fovnd to be very effective in reducing the nematode population and significantly increased the yield.
