Late Blight in Potato

The primary host is potato, but P.infestans also can infect other solanaceous plants, including tomatoes, petunias, and hairy nightshade, that can act as source of inoculum to potato. The first symptoms of late blight in the field are small, light to dark green, circular to irregular-shaped water-soaked spots (Figure 1). These lesions usually appear first on the lower leaves. Lesions often begin to develop near the leaf tips or edges, where dew is retained the longest.
