Se estudio la diseminacion de la anthracnosis (Colletotrichum lindemuthianum raza, delta) desde un foco de infeccion original en 1978-79, en parcelas de campo sembradas con un cv. de frijol blanco Fleetwood susceptible. La lluvia al salpicar disemino la enfermedad a distancias cortas aunque algunas plantas adyacentes a plantas enfermas no se infectaron. La diseminacion a distancias largas, 3- 4.6 m/aguaceros, se origino por las gotas de lluvia que salpicaron impulsadas por las rafagas de viento. La diseminacion de la enfermedad desde el foco de infeccion hacia la cuartilla noreste de la parcela siguio la direccion de los vientos predominantes. La severidad de la enfermedad fue mayor cerca al eje del sector mas cercano al foco de infeccion inicial y disminuyo gradualmente hacia la periferia del sector. El hongo requirio cerca de 10 mm de lluvia para establecer la infeccion. En el sur de Ontario, la temp. no fue un factor limitante para la infeccion y diseminacion de la enfermedad, pero temp. mayor de 25 grados centigrados restringen el desarrollo de la enfermedad.

Spread of anthracnose (Colletotrichum lindemuthianum, delta race) from an initial infection focus was studied in 1978-79 in field plots planted with a susceptible white bean cv. Fleetwood. Splashing rain spread the disease for short distances, although some plants adjacent to diseased plants did not become infected. Long-distance spread, 34.6 m/rainstorm, was caused by splashing raindrops blown by gusting winds. Disease spread from the infection focus toward the NE quarter of plot followed the direction of prevailing winds. Disease severity was highest at or near the axis of the sector nearest the initial infection focus and decreased gradually toward the periphery of the sector. The fungus required about 10 mm of rain to establish infection. In s. Ontario, temp. was not a limiting factor for infection and disease spread, but temp. more than 25 degrees celsius appeared to restrict disease development. (AS) eng
