Abstract

Efficacy of seed washing, garlic extract, prewashed seeds treated with garlic extract, Knowin 50 WP (Carbendazim) and prewashed seeds treated with Knowin 50WP were evaluated on seed borne fungi of jute seeds. Nine seed borne fungi were detected on both deshi and tossa jute seed samples collected from sadar upazilla of Barisal district viz., Macrophomina phaseolina, Botryodiplodia theobromae, Fusarium spp, Colletotrichum corchori, Curvularia lunata, Aspergillus flavus, A. niger, Penicillium spp. and Alternaria spp.. Physical seed washing and garlic extract were found effective against seed borne diseases of jute which significantly decrease the association of seed borne fungi from jute seeds. Prewashed seeds treated with garlic extract showed highest germination and highest reduction of seed borne mycoflora from desi and tossa jute seeds. Knowin 50WP or prewashed seeds treated with Knowin 50WP were found effective to reduce seed borne fungi from jute seeds. Highest vigor index was obtained in jute seedlings raised from prewashed seeds treated with Garlic or Knowin 50WP. Thus, prewashed seeds treated with Garlic or Knowin 50WP resulting significant reduction of seed-borne fungal population and enhancing seeding vigor.Asian J. Med. Biol. Res. June 2016, 2(2): 318-323

Highlights

Jute is an important cash crop in Bangladesh and India, which together accounts for about 84% of world production of jute fibre (BJRI, 2008)
Total seed borne fungi were lowest in prewashed seeds treated with Knowin 50WP, while the second best performance was recorded by the treatment with prewashed seeds treated with garlic extract
The lowest germination (58.66%) of seeds was found in untreated (T0) seeds and the highest (96.007%) germination was found on prewashed seeds treated with garlic extract (T3) and prewashed seeds treated with Knowin 50WP @ 0.2 (T5)

Summary

Introduction

Jute is an important cash crop in Bangladesh and India, which together accounts for about 84% of world production of jute fibre (BJRI, 2008). Fakir (2000) reported 10 seed borne diseases of jute in Bangladesh. There are about 10% production loss of jute may be incurred annually due to seed-borne fungal diseases in Bangladesh (Nitul, 2009). It is unquestionable that proper disease control measures should be taken for the production of quality jute seeds. Proper disease control measures can substantially improve the quality of jute and significantly increase the fiber yield. Generally with a combination of selective fungicides, is a standard practice for control of the seedling disease complex (Minton and Garber, 1983). It is published that seed cleaning, washing and seed treatment reduce disease incidence in seedlings (Asad-ud-doullah et al, 2002).
