Abstract/ Executive Summary:

A field experiment was conducted in three locations viz. Babuganj, Barisal; Dumki, Patuakhali and Patuakhali sadar, Patuakhali during 2013-14 to observe the performance of IPM package against leaf eating caterpillars in cabbage 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 head (2.42%) and produced higher head yield (54.94tlha) than farmers' practice. The highest benefit cost ratio (BCR) of 3.82 was also obtained from the IPM treatment.

Location: Babuganj, Barisal; Dumki, Patuakhali and Patuakhali sadar, Patuakhali

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Pest Management

Commodity: Cabbage

Objectives:

To evaluate the performance of the IPM package against leaf eating caterpillars in cabbage under farmer's field condition.

Methodology:

The experiment was carried out at the farmer's cabbage field at Babuganj, Barisal; Dumki, Patuakhali and Patuakhali sadar, Patuakhali, during 2013-14. It was laid out with 3 dispersed replications. The unit plot size was 0.2 ha. and total area was 0.6 ha. There were two treatments viz. T1: IPM package (sex pheromone trap +sanitation) and T2 = Farmers practice (spraying of insecticides). The sex pheromone traps were placed with 10m x 10m spacing in the field. Data on fruit infestation were recorded from randomly selected areas/plot at each harvest. Yield and infestation data were also recorded from both IPM and farmers' practice field. The gross economic return was calculated on the basis of prevailing market price of the commodities.

Total Budget (Tk.) :

Achievement/Findings:

The results indicated the performance of IPM package to reduce head infestation of cabbage was encouraging. IPM plots provided 83.96% head infestation reduction over farmers practice resulting in 28.72% higher yield. Highest gross return of Tk. 8,24,100 , net return of Tk. 6,52,950 and BCR of 3.82 was recorded from IPM package .
