Efeito de composto orgânico sobre podridões radiculares no feijoeiro comum. Bioscience Journal, Uberlândia, v. 30, n. 1, p. 25-32, jan./fev. 2014.e- 1981-3163http://repositorio.bc.ufg.br/handle/ri/14924The soil inhabiting fungi, Rhizoctonia solani and Fusarium solani f.sp. phaseoli, constitute an etiological complex with synergic interaction, responsible for up to 50% losses in common beans. Organic matter of diverse sources is used in agriculture to stimulate microbial activity limiting the activity of soil inhabiting plant pathogens, among other uses. This study evaluated the effect of organic compound doses on root rots caused by R. solani and F. solani f.sp. phaseoli, in common beans, cultivar Pérola, in field conditions. The experimental design was randomized blocks, as a 2 x 6 factorial. The organic compounds of Crotalaria juncea or Paspalum notatum, associated with poultry bedding, were applied in the planting furrow at the doses de 0, 20, 40, 80, 160 or 320 kg.ha -1 . Evaluations of severity were done using a rating scale. Greater severity of F. solani f.sp. phaseoli in common bean plants were observed at the dose of 320 kg.ha -1 crotalaria + poultry bedding e 80 kg.ha -1 with paspalum compound + poultry bedding. The organic compounds and doses did not affect R. solani severity. The dose of 80 kg.ha -1 , regardless of the organic compound, resulted in greater yield.porAcesso AbertoRhizoctonia solaniAgricultura orgâniaFusarium solani f.sp. phaseoliPhaseolus vulgaris L.Rhizoctonia solani,Organic agricultureFusarium solani f.sp. phaseoliSuppressivenessPhaseolus vulgaris L.SupressividadeArtigo
