Abstract/ Executive Summary:

Field experiments were conducted at three locations viz. Bakshirchar, Babuganj, Barisal; Lebukhali, Dumki, Patuakhali and Patuakhal sadar, Patuakhali during 2013-14 to observe the performance of IPM package against brinjal shoot and fruit borer in brinjal under farmer's field condition. Pooled data of three locations revealed that, crop under IPM package (sex pheromone trap + sanitation) received comparatively lower percentage of infested fruit (1.17%) and produced higher fruit yield (44.82 t/ha) than farmers' practice. Farmers practice received highest percentage of infested fruit (39.93%) and offered lowest fruit yield (27. 76 t/ha). The highest benefit cost ratio (BCR) (4.44) was also obtained from the IPM package.

Keywords: Sex pheromone,IPMpackage, Brinjil,Shot and fruit borer, Barisal region

Location: Bakshirchar, Babuganj, Barisal; Lebukhali, Dumki, Patuakhali and Patuakhal sadar, Patuakhali

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Pest Management

Commodity: Brinjal

Objectives:

To observe the performance of the IPM package against brinjal shoot and fruit borer farmer's field condition

Methodology:

The trial was carried out at farmers' field of three locations viz. Bakshirchar, Babuganj, Barisal; khali, Dumki, Patuakhali and Patuakhal sadar, Patuakhali during 2013-14 to observe the performance of IPM package against brinjal shoot and fruit borer in brinjaI. The experiment was laid n RCBD with 3 dispersed replications. The unit plot size was 0.2 ha and total area was 0.6 ha. e were two treatments viz. T₁: IPM package (sex pheromone trap+ sanitation) and T₂ = Farmers ice (spraying of insecticides). The sex pheromone traps were placed with 10m x 10m spacing e field. Data on fruit infestation were recorded from randomly selected areas/plot at each est. Yield and infestation data were also recorded from both IPM and farmers' practiced field. gross economic return was calculated on the basis of prevailing market price of the commodities.

Achievement/Findings:

The results indicated that performance of IPM package to reduce fruit infestation by brinjal shoot fruit borer on brinjal was encouraging. Pooled data of three locations revealed that, crop under package (sex pheromone trap + sanitation) received comparatively lower percentage of infested (1.17%) and produced higher fruit yield (44.82 t/ha) than farmers' practice. Farmers practice ved highest percentage of infested fruit (39.93%) and offered lowest fruit yield (27.76 t/ha). highest benefit cost ratio (BCR) (4.44) was also obtained from the IPM package. No. of red adult insect/trap/ week was 25 in treatment T _I (IPM package).
