Turnip Mosaic Virus (TuMV) infects most cruciferous plants, but is most damaging in Chinese cabbage, turnip, mustard, and radish. The most common symptom in these crops is a distinct mosaic of light and dark green colors in the leaves. Depending upon the virus strain and the crop species, necrotic streaks, flecks, or ringspots may also occur. Necrotic spots and ringspots are the primary symptom in common cabbage, but the severity of symptoms is cultivar dependent.
The Guide is divided into three sections. The first section provides cultural information and management practices for a number of important vegetable crop groups. For each family, key pests and disease problems are described. Cultural methods and management practices that will help control each problem are listed, as well as materials that may be recommended for use.
Vegetable seeds can be saved to sow new crops in the future, but not all seeds are suitable for saving. Varieties suitable for seed saving include local varieties that have been grown in one region for a very long time, self-pollinating crops (for example, beans and peas), and open-pollinated varieties of some cross-pollinating crops (for example, pepper, cucumber and carrot).
