Notes:
In 1975 and 1976 commercial potato crops, mainly cv. King Edward, grown on farms in Bedfordshire, Cambridgeshire and Hertfordshire were sampled to investigate the possibilities of forecasting storage disease from assessment of actual disease or latent infection, both on the seed tubers used and on the growing crop. Crops were stored in various conditions on the farms where they were grown or in a common store at the Potato Marketing Board Experimental Station at Sutton Bridge, Lincolnshire, at 3°C in 1975 or at Rothamsted in 1976.Skin spot, silver scurf and black scurf showed the greatest range of disease incidence between crops and skin spot the closest relationship between latent infection in growth and disease in store. In general the closer to harvest that tests were done, the closer the relationship to subsequent disease in store.In each year potatoes from only one farm had much gangrene and this was related to the incidence on the seed used and to the large amount of damage done to these tubers at harvest. There was little bacterial soft rot in either year. The assessments of disease and inoculum potential did not produce results sufficiently closely related to the amount of subsequent storage rot or disease to be helpful in making decisions on storage strategy, although the potential benefits from accurate forecasting would be great.
