ABSTRACT

Several management approaches against red ant of potato Dorylus orientalis (Westwood) were studied at farmer’s field near Hill Agricultural Research Station, Khagrachari during 2008-09 and 2009-10 cropping seasons to find out the most effective management technique. Dursban 20 EC and Sevin 85 WP reduced red ant damage significantly. From both the season (2008-09 and 2009-10), three times application of Dursban 20 EC @ 5ml/lit of water around the root zone starting from 45 days after sowing of potato tuber at 10 days interval gave the lowest tuber infestation (17.28% and 10.68%) with (62.77% and 56.60%) infestation reduction over control closely followed by 3 times application of Sevin 85 WP @ 3 gm/lit of water (20.14% and 13.73%) with (85.77 % and 81.71%) infestation reduction over control. Both the season the highest infestation (46.41% and 75.06%) was recorded from the control treatment.
