Several species of fungi belonging to 20 genera were isolated from bean seeds obtained from small farmers in the states of Huila, Valle del Cauca, Antioquia and Narino (Colombia). Seeds from Huila had a higher percentage of fungi and germination in vitro was lower than for seeds from the other st...

Diseases are one of the limiting factors to bean production in L.A. The prevalency and severity of the disease depends on the quantity of inoculum existing in the region, environmental conditions and the quality of the seed used. Data are given on geographic distribution, favorable climatic condi...
