Abstract

White mold has been responsible for expressive damages to the common bean crop. This study aimed at evaluating the effect of light regimes used for producing Trichoderma harzianum conidia and the effectiveness of these to inhibit the myceliogenic germination of Sclerotinia sclerotiorum sclerotia, as well as the effect of T. harzianum isolates in the suppression of lesions caused by S. sclerotiorum on common bean leaflets. The CEN287 isolate inhibited the myceliogenic germination in 80 % of the sclerotia evaluated. Such effectiveness was indifferent, regarding the light system used to obtain the T. harzianum conidia. The CEN287, CEN288 and CEN316 isolates showed the lowest average values ??of leaf lesion at 10 days after inoculation, being respectively 4.25 mm2, 2.97 mm2 and 2.98 mm2. Concerning the control, these values ??were significantly lower (72.90 mm2), what prevented the early deterioration of plant tissue.
