Summary
Six fungicides, i.e. carbendazim 50% WP, mancozeb 75% WP, copper oxychloride 50% WP, thiophanate-methyl, propineb, phenyl pyrrole (at 0.05, 0.1, 0.15 and 0.2%), and leaf extracts from 18 plants were tested against S. sclerotiorum using the food poison technique. Carbendazim, thiophanate-methyl and phenyl pyrrole completely inhibited the growth of the pathogen at all concentrations, thereby resulting in the lowest number of sclerotia. Mancozeb was found effective at higher concentrations. Copper oxychloride was the least effective, as it did not substantially decrease the growth of S. sclerotiorum compared with the control. Extracts of Allium cepa, Azadirachta indica, Datura stramonium, Ocimum tenuiflorum, Polyalthia longifolia, Tagetes erecta, Catharanthus roseus, Withania somnifera and Allium sativum inhibited the sclerotial formation almost completely, allowing the formation of 0.71-1.77 sclerotia per plate. Other treatments enhanced the sclerotia production from 2.03 to 4.10 sclerotia per plate, against 2.18 of the control.
