A novel potato seed treatment, which could be available next season, promises to give good control of skin spot and common scab, said SAC’s Stuart Wale.


Syngenta’s fludioxinil-based formulation showed “dramatic” reductions in skin spot and common scab infections in a number of trials, he said at the 2010 Crop Protection in Northern Britain Conference. The treatment would be particularly useful on susceptible varieties and in areas where it was difficult to irrigate, he believed.

A roller-table should be used to apply the product and it was critical to get good coverage, Dr Wale said. “All varieties are suitable, but it should only be applied to healthy tubers before chitting.”

The product was not yet approved, but he hoped it would be available for the 2011 season.
