In-vitro evaluation of different fungicides and botanicals against Fusarium oxysporum f. sp. ciceris

Résumé fourni par la source

Fusarium wilt of chickpea caused by Fusarium oxysporum f. sp. ciceris has been emerging as one of the biotic threats in profitable cultivation of chikpea crop. The fungicides evaluated in vitro against Fusarium oxysporum f. sp. ciceris were significantly reduced the mycelial growth. Five chemicals viz. Mancozeb 63% WP, Thiophanate methyl 70WP, Carbendazim 12% WP + Mancozeb 63% WP, Carboxin 37.5% DS + Thiram 37.5% DS and Tebuconazole 25.9% SC at 100, 250 and 500 ppm concentration evaluated by poison food technique. Among that Carboxin 37.5% DS + Thiram 37.5% DS were found most effective with maximum growth inhibition (100%) while Mancozeb 63% WP was found least effective at 100, 250 and 500ppm concentration. Among the botanicals tested against Fusarium oxysporum f. sp. ciceris, the garlic bulbs extract (Allium sativum) was found most effective with minimum mycelial growth (30.42 mm) and (27.30 mm) at 5% and 10% concentration respectively with (65.23) and (68.80) growth inhibition. while maximum mycelial growth was found in ashwagandha (48.55 mm) with 44.51 percent growth inhibition at 5% concentration and (42.74 mm) with 51.15 percent growth inhibition at 10% concentration.
