EXTRATOS DE PIMENTAS ( Capsicum spp.) PARA INIBIÇÃO DO CRESCIMENTO MICELIAL IN VITRO DE Rhizoctonia solani Kuhn

The aim was to evaluate in vitro the efficiency of different extracts of peppers on the Mycelial growth of Rhizoctonia solani . The experimental design used was the completely randomized design with 23 treatments, composed of 10 aqueous extracts, 10 alcoholics extracts and three controls (water, alcohol and fungicide), with four replicates. The data were subjected to analysis of variance and means comparison test (Tukey) (p < 0.05). Mycelial growth was determined to assess the possible effects of inhibition by determining the diameter. At the same time was conducted tests of volatile compounds. The crude extracts tested, five were efficient in inhibiting mycelial growth of R. solani : aqueous extracts of leaves of mexican chilli,
