Resumo: | Four isolates of Sclerotinia sclerotiorum were tested for pathogenicity in IPA-10 variety bean plants (Phaseolus vulgaris L.), and all were pathogenic. Biological control in vitro was evaluated using eight isolates of Trichoderma spp. and, one of Ulocladium atrum. Chemical control in vitro with fungicides Thiophanate methyl, Iprodione and Carbendazim was also tested. Except U. atrum, all Trichoderma isolates showed antagonistic potential against S. sclerotiorum, where isolate 3601 presented the best performance. Thiophanate methyl chemical control was the most efficient. This fungicide and isolate 3601were compared in vivo in greenhouse. There was statistical difference between the treatments, and the application of fungicide and antagonist before the pathogen was the most efficient approach, reducing the percentage of pathogenicity to 32.94% and 37.04%, respectively.
