Resumo: The objective of this work was to evaluate the effect of chitosan on common bean (Phaseolus vulgaris) anthracnose. Different concentrations of chitosan suspension were sprayed on plants at V3 stage, ingreenhouse; plants were also infected with Colletotrichum lindemuthianum. The concentration of 9 mg per plant reduced the anthracnose severity in more than 50%, without causing any toxic effect on bean plants. The protecting effect was local and more intense in a time interval of 4 days between treatment and inoculation.Mycelium growth reduction and spore germination inhibition of C. lindemuthianum were observed, when chitosan was used at 1 mg mL‑1 and 80 μg mL‑1, respectively. Chitosan increased the glucanase activityin bean leaves. Chitosan presents antifungal properties against C. lindemuthianum, as well as potential to induce resistance on bean plants. Therefore, the plant spraying with chitosan can be an alternative to control anthracnose.

A quitosana foi pulverizada em plantas de feijão-comum, em diferentes concentrações, no estádio V3, em casa de vegetação. As plantas foram também submetidas à inoculação de Colletotrichum lindemuthianum. A dose de 9 mg de quitosana por planta propiciou redução em mais de 50% na severidade da antracnose e não causou fitotoxicidade. O efeito protetor foi local e mais intenso no intervalo de tempo de 4 dias entre tratamento e inoculação. Observou-se redução significativa no crescimento micelial e inibição total da germinação de esporos de C. lindemuthianum, quando se utilizou o polissacarídeo a 1 mg mL‑1 e 80 μg mL‑1,respectivamente. Em folhas do feijoeiro, a quitosana provocou o aumento na atividade de glucanase. Quitosana apresenta propriedades antifúngicas contra C. lindemuthianum, bem como potencial para induzir resistência à planta, e pode ser uma alternativa para o controle da antracnose do feijoeiro.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFUNPESQUISA/UFSCDi Piero, Robson MarceloGarda, Marcos Venicius2008-10-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/242Pesquisa Agropecuaria Brasileira; v.43, n.9, set. 2008; 1121-1128Pesquisa Agropecuária Brasileira; v.43, n.9, set. 2008; 1121-11281678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/242/5489info:eu-repo/semantics/openAccess2014-07-16T17:01:16Zoai:ojs.seer.sct.embrapa.br:article/242Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-16T17:01:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
