- Abstract
The article reports on different diseases of outdoor-grown tobacco in England discovered in 1974 and 1975. An outbreak of blue mould (Peronospora tabacina Adam.) was found in one of the crops in Surrey. The disease caused severe damage to numerous cultivars in plots which received no fungicide treatment. The first visible symptoms were small chlorotic spots on the mature leaves. Cucumber mosaic virus and potato virus Y were also found at a Surrey site and the former also in a small experimental crop in Kent, and tobacco veinal necrosis virus was isoiated from trial plots in Essex. Infected plants usually showed an indistinct leaf mottling with some narrowing of the lamina, but on some plants there were bolder chlorotic blotches or ringspots.
