Abstract/ Executive Summary:

Several management approaches were studied against red ant of potato 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. In both the seasons, three times application of Sevin 85 WP @ 3 gm/litre of water around the root zone gave the highest tuber infestation reduction over control (64.53% and 85.70% in 2008-9 & 2009-10 respectively). Significantly the highest yield (15.22 t/ha and17.76 t/ha in 2008-9 & 2009-10 respectively) was also obtained from three times application of Sevin 85 WP.

Location: Khagrachari

Start Date: 14-11-2009

End Date: 05-04-2010

Program Area: Pest Management

Commodity: Potato

Objectives:

To find out suitable management practices options for potato red ant.

Methodology:

The experiment was carried out at farmer’s field near Hill Agricultural Research Station, Khagrachari during 2009-2010 cropping season to find out suitable management option for the control of red ant of potato. Diamant variety of potato was used in the experiment. Plot size was 3m×3m and spacing was maintained as 60 cm× 40 cm. Recommend dose of fertilizers was applied and other intercultural operations were done uniformly. Treatments were assigned in a RCB design with 3 replications. There were seven treatments as follows: T₁: Application of Neem oil cake @ 300 kg/ha during final land preparation, T₂: Application of Poultry manure @ 3 ton/ha during final land preparation, T₃: Application of Dursban 20 EC @ 5 ml/litre of water for 3 times, T₄: Application of Sevin 85 WP @ 3 gm/litre of water for 3 times, T₅: Application of Kerosine @ 5 ml/litre of water for 3 times, T₆: Application of Furadan 5G @ 40 kg/ha for 3 times and T₇: Untreated control. Neem oil cake was applied at final land preparation; insecticides and kerosine were applided 3 times at 10 days interval starting from 45 days after sowing. During final harvest data were taken on weight of healthy and infested tubers and percent infestation was calculated. Yield data of different treatments were recorded.
