Abstract/ Executive Summary:

The IPM package consisting of hand picking and destruction of infested flowers and pods with pod borer larvae, cutting of older leaves and twisted young twigs along with spraying of Tracer 45SC @ 0.4 ml per litre of water at 7 days interval reduced the damage of flower and pod significantly and consequently this package increased the yield. Considering the yield, other packages may also be considered for adoption.

Keywords: IPM, pod borer, country bean

Location: Jessore

Start Date: 24-11-2009

End Date: 10-04-2010

Program Area: Pest Management

Commodity: Country bean

Objectives:

To develop an integrated pest management (IPM) package for the control of legume pod borer in country bean production.

Methodology:

A trial was carried out during Rabi season 2009-10 at Regional Agricultural Research Station, Jessore to develop effective integrated pest management (IPM) package(s) for controlling the legume pod borer. The study was laid out in a randomized complete block design with three replications. Country bean seeds (local) were sown on 05 June, 2009 in 18 plots each measuring 3.0 m x 1.5 m. A distance of 1.5 m was maintained between plots and 2.0 m between replications. The IPM packages were as follows: IPM package 1 : This package consists of collection and destruction of infested flowers and pods with pod borer larvae by hand picking at 7 days intervals starting from the first incidence, cutting of older leaves and twisting young twigs by sharp knife as and when necessary and then removal from bean field were done and Tracer 45 SC @ 0.4 ml per litre of water was sprayed at 7 days interval commencing from first incidence of legume pod borer to the end of the study. IPM Package 2 :. Hand picking and cutting as above described in IPM package 1, integrated with spraying of Voliam Flexi 300SC @ 0.5 ml per litre of water at 7 days interval commencing from the first incidence of legume pod borer to the end of the trial. IPM Package 3 : Hand picking and cutting as similar with earlier package 1, integrated with spraying of Proclaim 5 SG @ 1.0 g per litre of water at 7 days interval commencing from the first incidence of legume pod borer to the end of the study. IPM Package 4 : This was composed of hand picking and cutting as done before and spraying of Belt 24 WG @ 0.4 g per litre of water at 7 days interval commencing from the first incidence of legume pod borer to the end of the trial. IPM package 5 : Hand picking and cutting as done earlier and spraying of Guilder 5SG @ 1.0 g per litre of water at 7 days interval commencing from the first incidence of legume pod borer to the end of the study. Untreated control: Water was sprayed at 7 days interval commencing from the first incidence of legume pod borer to the end of the study.
