Listed here is every problem for which the sources name this plant as a host. The problems are not listed in order of how common they are.
Powdery mildew
disease- Signs
- A white, floury coating spreads over the leaves, first on the lower and older ones. The leaf under it yellows and dries up. The fruit stays small, because the plant loses leaf surface.
- Prevention
- Plant resistant varieties, leave an airy spacing and sun, and clear the debris at the end of the season. Unlike most fungi it is not helped by wet foliage, since it spreads in heat and high air humidity, in a dry summer too. On soil that holds moisture it is less frequent.
