Abstract/ Executive Summary:

The crude seed extract of neem, black pepper, mahogani, and garlic bulb with three doses were evaluated against legume pod borer in the country bean field in two seasons kharif 2006 and rabi 2006-2007. The neem seed extract applied @150 and 100 g/l and mahogani seed extract @ 100 g/l of water 7 days intervals on the country bean showed better performance in the reduction of flower and pod damage with significantly higher yield of bean in both the seasons. The seed extracts lost the efficacy against legume pod borer after 7 days of application.

Keywords: Indigenous plant materials, Crude extract, Country bean, Legume pod borer

Location: Regional Agricultural Research Station, Jessore

Start Date: 00-00-2006

End Date: 00-00-2007

Program Area: Pest Management

Commodity: Extract (plant, seed)

Objectives:

To evaluate the efficacy of crude seed extracts of different plants against legume pod borer in the country bean field.

Methodology:

The trial was carried out for two consecutive seasons viz. kharif 2006 and rabi 2006 - 07 at Regional Agricultural Research Station, Jessore to evaluate the effectiveness of four plant extracts with three doses along with a control against legume pod borer. The country bean seeds (Barinagar local) were sown on 21 June, 2006 in 54 plots each measuring 3.0 m x 1.5 m. Treatments were assigned in randomized complete blook (Factorial) design with three replications and spacing of 1.5 m and 2.0 m between plots and blocks, respectively. Intercultural operations were done as and when necessary. Fertilizers were applied as per recommendation. Four botanicals viz., seeds of neem (Azadirachta indica), black pepper (Piper guineense), mahogani (Swietinia mahogani), and garlic bulb (Allium sativum) were collected from different locations of Bangladesh. Freshly collected 600 g seeds of neem, black pepper, mahogani, and garlic bulb were crushed by electric grinder separately one day before the schedule spray. The crusher machine was washed and cleaned properly after crushing each material. The crushed materials were transferred to the plastic bucket separately. Three litres of water was added to the crushed plant material in a separate plastic bucket and left for 12 hours. After 12 hours, plant extract was separated from crushed plant materials by decanting through a muslin cloth. This extract was considered as a stock extract. The extract contained active components from 200 g test material per liter of water. It was diluted to contain active components from 50 g, 100 g, and 150 g per litre of water. The process was repeated for all the cases and the cloth was washed at each time. Treatments were as follows: T₁ = Spray of neem seed extract @ 50g, 100g, and I 50g per litre of water at an interval of 7 days commencing from first incidence of legume pod borer. T₂= Spray of neem seed extract @ 50g. 100g, and 150g per litre of water at an interval of 14 days commencing from first incidence of legume pod borer. T₃= Spray of black pepper seed extract @ 50g, 100g and 150g per litre of water at an interval of 14 days commencing from first incidence of legume pod borer. T₄= Spray of garlic bulb extract @ 50g, 100g, and 150g per litre of water at an interval of 14 days commencing from first incidence of legume pod borer. T₅= Spray of mahogani seed extract @ 50g, 100g, and 1 50g per litre of water at an interval of 7 days commencing from first incidence of legume pod borer. T₆ = Untreated control. The above mentioned doses of different crude seed extracts were sprayed on the bean plants using knapsack sprayer. Knapsack sprayer was washed and cleaned after each plant extract spraying. Only water was sprayed in untreated control plot. Number of healthy and infested flowers were counted and recorded at 14 days interval from 25 inflorescences randomly selected per plot before spray and to calculate percentage of flower infestation at each observation. The pods were harvested from each treatments before each spray. At each harvest, number of healthy and infested pods were recorded and weighed to calculate percentage of pod infestation. The number of legume pod borer larvae were counted and recorded from randomly selected 10 infested pods before spray and after 24 hours of spray to calculate percentage of surviving larvae. All the data were analyzed statistically after appropriate transformations and the means were compared using DMRT by MSTAT computer software.

Achievement/Findings:

The neem seed extract applied @150 and 100 g/l and mahogani seed extract @ 100 g/l of water 7 days intervals on the country bean showed better performance in the reduction of flower and pod damage with significantly higher yield of bean in both the seasons. The seed extracts lost the efficacy against legume pod borer after 7 days of application.
