Abstract/ Executive Summary:

Five management packages were evaluated against potato tuber moth (PTM) in the farmers field of Munshigonj during 2013-14. The lowest percent of tuber damage (O.54by number and 0.50 by weight) was observed in T₅ (Sex pheromone traps + Decis 2.5EC ) followed by T₄ (Sex pheromone traps + Karate 2.5 EC), although these were statistically identical. The highest yield was obtained from T₄ (25.28 t/ha) and it was stastically similar to T₃(Sex pheromone traps + hilling up). However the highest benefit cost ratio (2.37) was obtained from management package (T₃).

Keywords: Development, Integrated management, Potato tuber moth

Location: farmers field of Munshigonj

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Pest Management

Commodity: Potato

Objectives:

To evaluate potato tuber moth (PTM) in the farmers field

Methodology:

The experiment was conducted at farmers field of Munshigonj. The experiment was set at November 28, 2013 and laid out in a randomized complete block design (RCBO) with three replications. The unit plot size was 3m x 3m maintaining spacing 60cm x 25cm. Fertilizers were used at per recommended doses. Irrigation was given recommended doses. Five treatments were followed with untreated control as: T_I= Sex pheromone mass trapping starting from 15 OAP till to harvest; T ₂ = T_I + Irrigation (Last irrigation will be given 70 OAP); T₃ = T_I+ Hilling up (Last hilling up will be done 35 OAP); T₄= Karate 2.5 EC (Lambda- cyhalothrin) @ 2 ml I L of water at 15 days interval to spray on plant foliage and soil; T₅= T₁+ Decis 2.5EC (Deltramethrin) @ 2 mil L of water at 15 days interval to spray on plant foliage and soil; T₆ = Control. The crop was harvested on March 2, 2014. After harvest data on the percent of tuber damage by number and weight, healthy tuber (number and weight) and yield of tuber were collected and analyzed statistically.

Achievement/Findings:

From this experiment, it was observed that the treatments T₄(Sex pheromone + Karate 2.5EC) and T₃ (Sex pheromone + Hilling up) obtained the highest yield. Similarly the least damage tuber percent by number and weight were statistically similar in T₄ and T, treatments. On the other hand, the BCR was highest in T₃(Sex pheromone + Hilling up) treatment than T₄ and T_5.Therefore, from the results of the present study it was found that the treatment T ₃ (Sex pheromone + Hilling up) may control the pest throughout the cropping season effectively and economically.
