Abstract/ Executive Summary:

An experiment was conducted at Shibganj, Bogra and Godagari, Rajshahi during 2014-15 to reduce banana leaf and fruit beetle infestation at farmers’ field condition. Three treatments viz: T₁: Banana bunch covered with netting (54 inch long and 36 inch wide), T₂: Banana bunch covered with polyethylene bagging (54 inch long and 36 inch wide) and T₃: Farmers’ practice (with insecticide) was considered in this regard. More or less similar lower infestation was observed in T₁ and T₂ against Farmers’ practice (T₃) in both locations. In case of gross margin the highest value was obtained from T₂which was closely followed by T₁and the lowest in farmers’ practice.

Location: MLT site Shibganj, Bogra and FSRD site Kadamshahar, Godagari, Rajshahi

Start Date: 00-00-2014

End Date: 00-00-2015

Program Area: Pest Management

Commodity: Banana

Objectives:

To reduce banana leaf and fruit beetle infestation by netting/polyethylene bagging and to produce safe banana by reducing insecticide use.

Methodology:

The experiment was conducted at the MLT site Shibganj, Bogra and FSRD site Kadamshahar, Godagari, Rajshahi during 2014-15 to reduce banana leaf and fruit beetle infestation. It was laid out in RCB design with six replications. There were three treatments viz. (i) Banana bunch covered with netting (54 inch long and 36 inch wide), (ii) Banana bunch covered with polyethylene bagging (54 inch long and 36 inch wide) and (iii) Farmers practice (with insecticide; Sevin 5 times @ 2g/L). The unit plot size was 8m x 4m. Eight plants were considered per treatment. The variety was Rangin Maher Sagar in Bogra and Sabri in Rajshahi. Suckers were planted on 30 October 2013 in Bogra and 5 April 2014 in Rajshahi. The banana bunches were covered with nets/polythene bags during 5 June-20 June 2014 in Bogra and 5 December-5 January 2015 in Rajshahi irrespective of farmers and as per growth and development of bunch. Recommended fertilizer doses were used to grow the crop. Weeding, mulching, irrigation and removal of dried leaves were done as and when necessary. In polythene bag treatment, bags were checked to remove moisture from the bag. The crop was harvested treatment wise during 14 October to 12 November 2014 in Bogra and 7 March-18 April 2014 in Rajshahi. The data on date of maturity, number of fresh and infested fruits per bunch and market value were recorded from all the 8 plants in each plot and were analyzed statistically. The cost and returns were also calculated.
