Seeds provide an efficient method for disseminating pathogenic organisms to different locations; more than 50 percent of the major bean diseases are seed borne. Mechanical damage, which may occur during harvesting, threshing and/or planting, can affect seed viability, germination and contaminatio...

La semilla constituye un metodo eficiente de diseminacion de organismos fitopatogenos entre distintas localidades; mas del 50 por ciento de las principales enfermedades del frijol son transmitidas por semilla. El dano mecanico que ocurre durante la cosecha, trilla y/o siembra tambien puede afecta...
