In the departments of Nariño and Putumayo, since 2003 has been presenting a disturbance of apparent viral etiology attacking perennial bean (Phaseolus polyanthus Greenman) with symptoms of generalized yellowing, distortion of leaves, shoots and rugose mosaic and growth retardation. The completion of this work was done in the greenhouse and the laboratory of entomology at the University of Nariño, Pasto, Colombia, 2,600m, and an average temperature of 20°C. For the identification was made by collection of infected material for testing mechanical inoculation, aphid and seed transmission. Being able to establish that the efficiency of mechanical transmission in bean Phaseolus polyanthus Greenman is 90% with an end point dilution of 105, its in...
