tailieunhanh - Evaluation of various fungitoxicants and bio-agents in the laboratory and field against leaf spot and fruit rot of chilli caused by Alternaria alternata (fries) Keissler

Out of twelve fungicides and three bio-agents screened in the laboratory, Bavistin, Indofil M-45, Chlorothalonil, Vitavax and Thiram proved most effective as they caused total inhibition of the pathogen. Indofil Z-78, Captafol, Ziram, Captan and Blitox-50 were also found to be significantly superior compared to other fungicides. Out of five seed dressing fungicides and three bio-agents, Trichoderma viride proved to be the most effective followed by Trichoderma harzianum, Bavistin and Thiram in controlling the seed –borne infection of Alternaria alternata. However, none of the seed dressing fungicides was found effective in checking the secondary spread of the disease under field conditions. Out of eight spray fungicides, Indofil M-45 proved to be most effective in controlling the disease in pot culture experiment as well as in field trials, followed by Indofil Z-78 and Chlorothalonil. Application of Indofil M-45@ can be recommended for the successful management of Alternaria leaf spot and fruit rot due to Alternaria alternata under field conditions. | Evaluation of various fungitoxicants and bio-agents in the laboratory and field against leaf spot and fruit rot of chilli caused by Alternaria alternata (fries) Keissler
