- Abstract
The yield of beans (Phaseolus vulgaris L.) is diminished by the onslaught of disease throughout the crop cycle, reducing farmers' incomes in the central part of the Ecuadorian coast. The objective of this research was to identify which are the diseases that occur, and quantify them in 21 bean genetic materials in Quevedo city. Described the agents causing the damping off after emergence, and the diseases present in the bean agroecosystem. Also quantified the severity (%) of foliar diseases in plants and per plot, rust (Uromyces appendiculatus), web blight (Rhizoctonia solani) and incidence (%) of virus and root rot. Pathogens were found in the damping off (Fusarium spp. and R. solani), predominant foliar diseases (U. appendiculatus, R. solani and Macrophomina phaseolina), the presence of viruses and microorganisms promoters eventually root rot (fusarium, rhizoctonia and macrofomina). Different pattern was evident among the cultivars evaluated. The materials were a lower intensity of phytosanitary problems were the CAL - 96, EVG - 06 - 103, Cf4 0-0-4-8, INIAP-473 and Cf4 0-0-12-5.
