There are various viruses transmitted by aphids that infect beans in almost all countries; (1) BCMV causes yield losses from 35- 98 percent according to the var., time of infection and environmental conditions. The virus can attack any part of the plant and produces 3 types of symptoms: mosaic, n...

CIATs collection of promising bean lines was evaluated over a 2- mo period for resistance to web blight (Rhizoctonia microsclerotia) on a highly infested soil in Esparza, Costa Rica, where conditions are very favorable for the development of this disease. A scale of 1-5 was used, based on the per...
