Effect of fungicides on in vitro infestation level of radish, carrot and pepper seeds
Plant Pathology Journal 5 (3), 388-392
Abstract: Through incubation of radish (Raphanus sativus), carrot (Daucus carota) and pepper (Capsicum annuum) seed samples on potato dextrose agar at 25°C, six species of fungi were determined as seedborne in these crops. Alternaria dauci, A. tenuissima, A. tenuis and Epicoccum sp. were found to be transmitted by radish seed. For carrot seed, A. tenuissima, A. dauci, A. tenuis, Epicoccum sp. and Fusarium oxysporum were identified. However, Alternaria tenuissima and Botrytis cinerea were isolated from pepper seeds. Seed treated with fungicides such as Maneb, Mancozeb, Benomyl and Thiophanate methyl could reduce the infestation levels of tested crops.
