Management of brinjal seed mycoflora through fungicides in vitro
Author(s): Bhagora GJ, Gohel VR and Barad AJ
Abstract: Fungal infection on the seed adversely affects the seed quality, causing seed discoloration, reduced seed weight and density, poor germinability and reduced viability. Seed mycofora load on five cultivars of brinjal viz., GOB-1, Doli-5, GAOB-2, GABH-3 and ABH-1 was studied and Alternaria tenuis, Fusarium oxysporum, Aspergillus niger, A. flavus, Curvularia lunata, Penicillium sp. and Phoma sp. were found associated with seeds. Among all cultivar GOB-1 had highest number of seed mycoflora. Seed treatment of systemic and non-systemic fungicides of the cultivar GOB-1 seeds with carbendazim, tricyclazole, tebuconazole, thiram, captan and mancozeb at their respective concentrations revealed significant differences in per cent seed mycoflora. All the treatments reduced the seed mycoflora but none of the treatments gave complete control of all fungi. However, minimum number of fungal species (three) were recorded with thiram at 0.3 per cent with minimum per cent seed mycoflora (6.25%) followed by carbendazim at 0.1 per cent and tebuconazole at 0.1 per cent. Among all the fungicides, highest per cent seed mycoflora was observed with mancozeb at 0.3 per cent.
