The aim of this work was isolated from Trichoderma spp. aimed at the survival of seedlings of bean (Phaseolus vulgaris L.) cv. carioca in the presence of Sclerotinia sclerotiorum (Lib.) De Bary, as well promoting growth from that cultivation. The experiment aiming to ex vitro survival of bean plants were used four treatments (presence of isolated IT2, IT3 and IT4 of Trichoderma viride + control without Trichoderma spp.) Plantmax® in inoculated with S. sclerotiorum. The experimente has sought to control S. sclerotiorum ex vitro in bean plants, it were employed four treatments (absence and presence of isolated IT2, IT3 and IT4 Trichoderma viride) in substrate Plantmax® inoculated with S. sclerotiorum. The experiment in promoting bean plant growth was led in presence and absence of biological powder, from the mixture of three isolates of T. viride (IT2, IT3 and IT4), either in sterilized or not substrate, resulting in four treatments. In two of the studies, the treatments were ordered in outlining purely random, with seven repetitions and three plants in each of them. Isolates IT2, IT3 and IT4 afforded the highest survival rate among the bean plant against White mold (84,56; 65,32; 96,87% and 73,50; 43,17; 96,87% at 21 days and 35 days, respectively) unlike the control treatments (0% and 9,32%, respectively). The misture of the three isolates of T. viride promoted the highest plants, either using sterilized substrate or not (23,69 cm and 20,42 cm, respectively) if compared to the treatments without isolates (13,78 cm and 16,375 cm, respectively). In the presence of biological powder the avarages of dry mass were higher (6,42 and 6,579 g) and different from the sterilized substrate without biological powder (3,98 g). We conclude that the isolates tested T. viride are effective in controlling S. sclerotiorum, presenting higher percentages of bean plants survivors. The mixture of isolates also promotes the growth of seedlings of bean cv. Carioca.
