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 [PM package against leaf eating caterpillars in cauliflower under farmer's field condition. Pooled data of three locations revealed that crop under [PM package (sex pheromone trap + sanitation) received comparatively lower percentage of infested curd (2.59%) and produced higher yield (28.57 t/ha) than farmers' practice. The highest benefit cost ratio (BCR) (4.06) was also obtained from [PM package.

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Pest Management

Commodity: Cauliflower

Objectives:

To observe the performance of the package against leaf eating caterpillars in cauliflower under farmers field condition

Methodology:

The trial was carried out at the farmer's cauliflower field in three locations viz. Babuganj, Barisal; Dumki, Patuakhali and Patuakhali sadar, Patuakhali during 2013-14. The experiment 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 10 m x 10 m spacing in the field. Data on curd 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.

Achievement/Findings:

The results indicated that performance of IPM package to reduce curd infestation on cauliflower was encouraging. IPM plots provided 83.40% curd infestation reduction over farmers practice resulting in 26.25% higher yield .Highest gross return (Tk. 857100) and net return (Tk. 687575) and benefit cost ratio BCR (4.06) was recorded from IPM package.
