Seed-borne mycoflora of pigeon pea and its management

Abstract:

Pigeon pea (Cajanus cajan (L) Mill sp.) is one of the important pulse crops. Seed sample of different varieties of Pigeon pea viz., BDN-716, AKT-1188, PKV-Tara, Charu and Mahesh were collected and tested for different seed-borne mycoflora by four ISTA methods among four seed health testing methods, Standard blotter method was recorded with total fungi association. Whereas Rolled paper towel method recorded lowest association of fungi. Thirteen fungicides were tested for their efficacy in vitro by poison food technique at different conc. 0.1%, 0.2% and 0.3%. Among all treatments evaluated against pathogenic fungi Alternaria alternata fungicides tested Propiconazole 13.9% + Difenoconazole 13.9% EC, Tebuconazole 50% + Trifloxystrobin 25% WG, Propineb 70% WP and Benalaxyl -M 4+ Mancozeb 65% WP showed 100% growth inhibition of Alternaria alternata. Lowest mycelial growth inhibition was recorded Azoxystrobin 23% SC, followed by Sulphur 80% WDG.
