Abstract/ Executive Summary:

Management of Jassid (Empoasca terminalis) of groundnut using botanical and chemical insecticide viz. zet powder, neem kernel extract, biskatali dust extract and neem oil, Tafgar 20 EC and their integration was studied at Regional Agricultural Research Station, .Bangladesh Agricultural Research Institute, Rahmatpur, Barisal during rabi season of 2008-2009 and 2009-2010. The infestation of Jassid (Empoasca terminalis) was noticed during 1st week of March and the highest infestation of Jassid (Empoasca terminalis) was 345 per plant observed in the last week of April in 2009, 2010. Among the treatments as expected Tafgar 20 EC reduced the highest Jassid (Empoasca terminalis) (99.55%) with the highest BCR (5.65) followed by Neem kernel extract + Zet powder (56.32%), Neem oil + Zet powder (55.13%). Neem kernel extract (2.5%) + Biskatali dust extract (54.31) and Zet powder (48.33%) recorded at 15 days after spray over the pre-treatment count. Neem kernel extract + Zetpowder gave the second highest BCR (4.76) followed by Neem oil +Zet powder (4.29), Neem kernel extract (2.5%) + Biskatali dust extract (3.88) and Zet powder 4g/l of water (3.32).

Start Date: 00-11-2009

End Date: 00-03-2010

Program Area: Pest Management

Commodity: Ground nut

Objectives:

1. To find out the most effective plant materials with their integration for the management of jassid of groundnut.

Methodology:

The experiment was conducted in the field of the Oilseed Research Centre, Regional Agricultural Research station, Bangladesh Agricultural Research Institute (BARI), Rahmatpur, Barisal during rabi seasons of 2008-2009 and 2009-2010.The experiment was laid out in a randomized complete block design (RCBD) with three replications. The unit plot size was 6 m X 4 m. Fertilizers were applied at the rate of 25-160-85-300-5-10 kg/ha of urea, triple supper phosphate, muriate of potash, gypsum, zinc sulphate and borax respectively, as recommended for Bangladesh (Anon, 2004). One half amount of urea and full dose of all other fertilizers were incorporated into the soil at the time of final land preparation. The remaining urea was top dressed in two equal installments at 35 and 65 days after sowing. During land preparation, cowdung was applied at 10 ton/ha. The seeds were sown at the spacing maintained for groundnut was 30 cm row to row and 15 cm seed to seed distances. The groundnut variety BARI chinabadam-7 were sown in 10 December, 08 and 09. Intercultural operations, such as irrigation was given twice, weeding and mulching were done as and when necessary as per recommendation of Mondall and wahhab (2000). Six treatments namely, Zet powder @4g/l of water, Neem kernal extract (2.5%) + Biskatali dust extract, neem kernal extract+ Zet powder, Neem oil 5ml/l of water +Zet powder, Tafgar 20EC@ 1ml/l of water and untreated control were evaluated against Jassid of groundnut under field condition. Three hundred fifty gram (350g) neem seed kernal was crushed and added to 10 litre of water and keep to over night and sieved with fine net. Then the solution was ready for spray. Four gram (4g) detergent powder (Zet powder) added to 1 litre of water stirring and sieved with fine net. Four (4) ml neem oil added to 1 litre of water with 4 g zet powder stirring and sieved then the solution was ready for spray. Botanicals and chemical insecticide were applied on March 10, 2009, 2010 at the vegetative and pod formation stage of the crop with the help of knapsack sprayer. Randomly 10 plants were selected per plot for counting Jassid of groundnut. Jassid were counted on leaf and shoot of the plant before 5, 10 and 15 days after spray in all the treatments. The crop was harvested on 25-05-2009, 2010. Seed yield of different treatments were recorded. Recorded data were compiled and analyzed in the computer package program MSTAT-C for Randomized Complete Block Design (RCBD) and mean value were separated by Duncan’s Multiple Range Test (DMRT). Benefit cost ratios (BCR) of different treatments were also calculated.

Achievement/Findings:

Neem formations and Zetpowder are effective in checking the Jassid in groundnut only up to 10-15 days after spray. Their performance was inferior to Tafgar 20 EC treated plots. Although botanicals insecticides fail to reduce 100% Jassid but it safe for natural enemies and also safe for environmental pollution.
