Abstract/ Executive Summary:

An experiment was conducted in pot house and field condition of Plant Pathology Division at BARI, Gazipur during 2012-13 to test the efficacy of Mustard oil cake, Tricho compost, Savlon, Vitavax and Bavistin as soil drenching materials to control foot rot disease (Sclerotium rolfsii) of groundnut. In pot house study, seed treated with Vitavax (2.5 g kg-1) gave the minimum seed rot of groundnut although soil drenched with Bavistin (0.1%) reduced maximum foot rot of groundnut in seedling stage. In the field study, Vitavax decreased the maximum seed rot of groundnut seedlings and also gave the higher germination of groundnut seed. On the other hands, soil drencing with Bavistin gave the maximum reduction of foot rot infection of groundnut seedling. In both experiments, Bavistin and Vitavax gave considerable reduction of foot rot disease but the yield of groundnut was found higher when Vitavax applied. Seed treatment with Vitavax and soil drencing with Bavistin were reduced the foot rot disease and provided higher yield.

Start Date: 00-00-2012

End Date: 00-00-2013

Program Area: Pest Management

Commodity: Ground nut

Objectives:

To find out an effective management approach for Sclerotium rolfsii in groundnut

Methodology:

The field experiment was conducted in the field previously identified infested by Sclerotium rolfsii. The experiment was laid out in RCB design with three replications. Groundnut variety, BARI china badam-8 was used. The unit plot size was 3m×2m with a spacing 40cm×15cm. Intercultural operations were done as and when needed. The treatments were the same as used in pot house experiment. The plots were inspected regularly to observe the disease symptoms. Data were recorded on germination, seed rot, foot and root rot incidence, plant survival, number of nut plant^-1 and yield; and analysed using MSTAT-C program for both the experiments.

Achievement/Findings:

The germination t ofgroundnut in different treatments ranged from 73.45 to 88.58%. The maximum germination of the seed was recorded when Vitavax applied followed by Bavistin, MOC, Tricho-compost and Savlon treatments. On the other hand, the minimum seed rot (11.42%) was recorded in the Vitavax treatment. The control plot gave lower germination and higher seed rot. The foot rot infected plants in various treatments ranged from 17.34 to 35.46%. All the treatments significantly reduced foot rot of groundnut over control. The highest foot rot (35.46%) was recorded from control treatments and the lowest (17.34%) was found in Bavistin treatment. The plot treated with Bavistin gave minimum foot rot infection which differed significantly with all other treatments. In case of mature nut per plant, all the treatments gave the significant variation over the control. The maximum nut was harvested from Vitavax treated plot followed by Bavistin. The minimum nut was recorded in control treatment. The no. of unfilled nut per plant ranged 18.5 to 28.5 %. Although the treatment Vitavax gave the maximum immature nut but it showed statistically similar with Bavistin. Yield per plant in the treatments MOC, Tricho-compost, Bavistin was found similar but the highest (3.12 t ha^-1) production of groundnut recorded from Vitavax treatment. So Vitavax is found to be the best treatment to control the foot rot diseases of groundnut.
