Resumo: | Presently the common bean crop has been intensified during the Autumn-Winter season, with the purpose of exploring the growing areas for a longer period of time. In this planting time the occurrence of powdery mildew (Erysiphe polygoni) should increase due to the favorable environmental conditions. This study was carried out aiming at verify the effect of this pathogen on yield of common bean (Phaseolus vulgaris). For each cultivar a separate experiment was conducted, with and without chemical treatment, during two sowing times, April and August. In each experiment three treatments were evaluated: inoculation at 20, 30, and 40 days after sowing, with seven replications. The effect of the pathogen was more conspicuous as earlier was its occurrence, with average reduction on yield of 50% and 40% in cultivars Eriparza and Rio Vermelho, respectively, independently of the time the experiment was done. Results show that, to continue common bean sowing during this time, powdery mildew could become a pathogen of great nocivity to the economy. |

Nessa época de plantio, a ocorrência do oídio (Erysiphe polygoni) deverá ser incrementada, em face das condições ambientais favoráveis. O presente trabalho foi realizado com o objetivo de verificar o efeito do patógeno na produtividade de grãos da cultura do feijão (Phaseolus vulgaris). Para cada cultivar foram conduzidos experimentos separados, com e sem tratamento químico, em duas épocas de semeadura, abril e agosto. Em cada experimento foram avaliados três tratamentos: inoculação com 20, 30 e 40 dias após semeadura, com sete repetições. Verificou-se que o efeito do patógeno foi mais acentuado quanto mais precoce foi sua ocorrência, com reduções médias de produção de 50% e 40%, nas cultivares Eriparza e Rio Vermelho, respectivamente, independentemente da época em que foi conduzido o experimento. Os resultados indicam que, a continuar a semeadura do feijão nessa época, o oídio tornar-se-á patógeno de grande nocividade para a economia.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraArriel, Eder Ferreirados Santos, João BoscoRamalho, Magno A.
