Abstract:

Alternaria blight disease caused by Alternaria alternata is devastating disease. In this experiment total eight seed dressing fungicides at their recommended dosages were evaluated in-vitro by poisoned food technique, against Alternaria alternata caused by alternaria blight. The result revealed that treatment with carboxin 37.5% + thiram 37.5% 75WP @ 0.25% (85.98%) was found effective fungicide followed by tebuconazole 25 % WG @ 0.2 % (83.57), captan 75% WP @ 0.3% (66.42%), carbendazim 12% + mancozeb 63% 75WP @ 0.25% (63.33%), pyroclostrobin 20% WG @ 0.1% (45.10%), carbendazim 50% WP @ 0.1% (21.02%) and thiophanate methyl 70% WP @ 0.1% (14.33%), against Alternaria alternata. The eight bioagents evaluated against alternaria alternata by dual culture technique. The most effective bioagent was found T. hamatum (85.88%) followed by A. niger (77.00%), T. asperellum (74.77%), T. harzianum (74.00%), T. koningii (54.21%), T. longibrachatum (44.80%) and P. fluorescens (43.44%).
