Management of Anthracnose of Hyacinth Bean for Safe Fresh Food Production

Spices Research Centre, BARI, Shibganj, Bogra, BANGLADESH

Abstract/ Executive Summary:

The experiment was conducted with two sets at ARS, BARI, Pabna during 2008-09 to find out the effective control measure for anthracnose disease of country bean for producing safe fresh food without harmful chemicals. For experiment set 1 (fungal inoculum was sprayed before treatments apply), control treatment showed the highest leaf area diseased (27.67%) and Tilt 250 EC, Bordeaux mixture, Baking powder and Trichoderma harzianum sprayed plot showed lower leaf area diseased. Percent infected fruits varied from 12.23 - 25.56%, while the highest was in control and the lowest was in Tilt 250 EC sprayed plot. Control plot showed the highest fruit area diseased (3.20%) and Tilt 250 EC sprayed plot showed the lowest (1.33%) which followed by Bordeaux mixture (1.67%), Baking powder (1.97%) and Trichoderma harzianum (2.00%) sprayed plot. Tilt 250 EC sprayed plot resulted the maximum yield (9.17 t/ha). Bordeaux mixture (7.37 t/ha), Baking powder (6.25 t/ha) and Trichoderma harzianum (6.08 t/ha) sprayed plot also gave higher yield, and the lowest yield (4.00 t/ha) resulted control plot. Both the experiments gave similar trends of results.

Program Area: Pest Management

Commodity: Bean

Objectives:

To find out the effective control measure for anthracnose disease of country bean for producing safe fresh food without harmful chemicals.

Methodology:

The experiment was conducted with two sets at Agricultural Research Station, Pabna during 2008-09. The experimental land was well ploughed and properly leveled before bed preparation. Weeds and stubbles were removed from the field. Cow dung @ 10 t/ha, Urea @ 25 kg/ha, TSP @ 90 kg/ha, MP @ 60 kg/ha, Gypsum 5 kg/ha and Boric acid Gypsum 5 kg/ha were applied. BARI Hyacnth Bean-2 was used in this experiment. The unit plot size was 2.0 m x 2.0 m. For the experiment Set 1, fungal inoculum was sprayed before treatments apply and for experiment Set 2, fungal inoculum was sprayed after treatments apply. For both the sets, the experiment was carried out following Randomized Complete Block Design with three replications. Seven treatments were T₁ = Trichoderma harzianum broth (1:5) spray, T₂ = Trichoderma harzianum apply in Soil (2 kg NDS compost/plant), T₃ = Bordeaux mixture (1:1:100) spray, T₄ = Baking powder (0.5%) spray, T₅ = Dettol (2.0%) spray, T₆ = Tilt 250 EC (0.05%) spray and T₇ = Control (untreated) for both the sets of experiments. Treatments were applied in case of experiment set 1 three times at an interval of 10 days after two weeks of fungal inoculation, but treatments were applied for set 2 only once before inoculum spray. Intercultural operations were done as per needed and to maintain the normal hygienic condition of crop in the field. Data were recorded on % leaf area diseased, incidence of infected fruits, % fruit area diseased and yield (t/ha). The recorded data were analyzed statistically to find out the level of significance and the variations among the respective data were compared following Duncan’s New Multiple Range Test (DMRT).

Achievement/Findings:

It may be concluded that Tilt 250 EC (0.05%) was the best fungicide but safe chemicals. Bordeaux mixture (1:1:100) spray, Baking powder (0.5%) spray and biocontrol agent Trichoderma harzianum broth (1:5) spray also showed better performances as safe materials in controlling anthracnose disease and increasing yield (safe food) of hyacinth bean.
