UZMA SITARA AND SHAHIDA AKHTER
Abstract
Using standard blotter and deep freezing techniques, 7 genera and 11 species of fungi viz., Aspergillus niger, A. flavus, A. wentii, Chaetomium sp., Drechslera sp., Fusarium chlamydosporum, F. oxysporum, F. moniliforme, F. semitectum, F. nivale, Nigrospora sp., Phoma sp. and Rhizopus sp. were isolated from maize seeds. Seed treatment with fungicides viz., Antracol (70% WP), Aliette (80% w/ w), Ridomyl Gold (MZ 68% WP), Neem seed powder @ 0.1%, 0.2% & 0.3% and Sodium hypochlorite @ 10% were used. No adverse effects were observed on the germination of seeds in blotter method whereas the germination was reduced due to dead/frozen embryo in deep-freezing method. Ridomyl Gold was found to be effective against seed borne mycoflora of maize followed by Aliette, Neem seed powder, Antracol and Sodium hypochlorite.
