Online resources: In: Plant DiseaseSummary: Se describe un metodo integrado para el manejo del moho blanco del frijol (Sclerotinia sclerotiorum), desarrollado en Ontario (Canada), y que permite controlar la enfermedad efectivamente. El metodo combina el tratamiento de la semilla con DCT (diazinon 6 por ciento, captan 18 por ciento, metil tiofanato 14 por ciento) y la utilizacion de var. resistentes de frijol blanco como Ex Rico 23, o lineas derivadas de cruces a partir de ella, como OAC Rico, Crestwood y Centralia. La reduccion en el espaciamiento entre surcos y el incremento en la densidad de plantas tambien afectan notablemente la incidencia del hongo en el cultivo en las var. susceptibles. El porcentaje de incidencia en la var. Fleetwood (susceptible) aumento de 25 a 35 por ciento cuando el espacio entre surcos se redujo de 80 a 40 cm y en cambio la incidencia en Ex Rico 23 (resistente) aumento solo de 10 a 14 por ciento.

The method combines seed treatment with DCT (diazinon (6 percent), captan (18 percent), methylthiophanate (14 percent)) and use of var. resistant to the white mold, such as Ex-Rico 23, or lines derived from crosses starting from it, like OAC Rico, Crestwood, and Centralia. Reduced distance between furrows and increased plant density greatly affect fungus incidence in susceptible var. The percentage of incidence in var. Fleetwood (susceptible) increased from 25 to 35 percent when the space between furrows was reduced from 80 to 40 cm, while incidence in Ex-Rico 23 (resistant) increased from 10 to 14 percent only.
