Abstract

Beans (Phaseolus vulgaris) are one of the most important crops in human food, but the occurrence of disease can greatly reduce their productivity. The objective of this work was to evaluate the use of biotic and abiotic products to control angular spot (Pseudocercosporagriseola) in bean crop. Hight Roots® treatments; V6®; Wert Plus®, potassium phosphite; manganese phosphite; Copper phosphite, manganese, fungicide (fentin hydroxide), Ascophyllum nodosum, Bacillus subtilis and Bacillus thuringiensis, acibenzolar-S-methylic (ASM) and Trichoderma asperallum were used in greenhouse and field experiments with IPR Uirapuru cultivar. Biotic to abiotic products controlled angular leaf spot in bean plants. In greenhouse, the lowest values of Area Under the Disease Progress Curve (AUDPC) were obtained with fungicide application, A. nodosum, T. asperellum and copper phosphite, B. subtillis, acibenzolar-S-methyl, potassium phosphite, Hight Roots®, V6® and Wert Plus®. In field, in the first sowing season the treatments with fungicide, A. nodosum, B. thuringiensis and manganese resulted in lower AUDPC in relation to the other products. In the second sowing season, the tested products did not reduce the severity of the angular spot, since the productivity was higher for fungicide treatment. In the health quality of seeds, potentially pathogenic fungi such as Fusarium sp., Colletotrichum truncatum and Phomopsis sp., as well as the saprophytic fungus Aspergillus sp.
