Abstract	Control of silver scurf on daughter tubers was obtained by imazalil applied to seed tubers as a pre- or post-storage treatment or as a furrow treatment (at time of planting), in three field experiments. Post-storage and pre- and post-storage combination treatments provided consistent results. The most effective treatment in the first and second experiments was the combined pre- and post-storage application of imazalil. However, separate pre- and post-storage treatment also significantly reduced the incidence compared with the non-treated control. No differences were observed between dosages of 15 and 30 g a.i. of imazalil per ton of seed tubers.Although furrow treatment at planting time (1.5 1/ha) significantly reduced silver scurf incidence on daughter tubers, it was less effective than seed treatments. However, the combined treatment of pre-storage application and furrow treatment significantly reduced the disease and was more effective than the single pre-storage seed treatment. In the third experiment, a reduction of disease incidence and severity index was obtained by post-storage treatments or with the combination of pre- and post-storage applications.Se controló la costra plateada en tubérculos hijos aplicando imazalil a los tubérculos-semilla como tratamiento en pre y pos almacenamiento o como tratamiento en surcos (al momento de la siembra) en tres campos experimentales. La combinación de tratamientos de pre y pos almacenamiento produjo resultados consistentes. E1 tratamiento más efectivo en el primer y segundo experimento fue la combinación en la aplicación de imazalil durante el pre y pos almacenamiento. Sin embargo, el tratamiento por separado durante estos periodos también redujo significativamente la incidencia en comparacion con el control de los no tratados. No se observó diferencia entre las dosis de 15 y 30 g a.i. de imazalil por tonelada de tubérculos-semilla.Aunque el tratameinto en surcos al momento de la siembra (1.5 1/ha) redujo significativamente la incidencia de la costra plateada en los tubérculos hijos, fue menos efectivo que el tratameinto en las semillas. No obstante, el tratameinto combinado de aplicaciones pre y pos almacenamiento con el tratamiento en surcos redujo significativamente la enfermedad y fue más efectivo que solo el tratamiento de semillas pre y pos almacenamiento. En el tercer experimento se obtuvo una reducción de la incidencia de la enfermedad y del índice de severidad con tratamientos pos almacenamiento o con la combinación de aplicaciones pre y pos almacenamiento.
