Mildew, a disease caused by a fungus, is now widespread almost everywhere in Europe. Among other things, it nests in the grape vines. This has serious economic consequences, but what about human he alth? Can you still eat fruit from a plant affected by powdery mildew? Find out here.
Are mildew grapes edible?
Grapes affected by mildew are generally edible and not poisonous. However, allergic reactions such as stomach upset, digestive problems, difficulty breathing or skin rashes can occur. The taste of wine made from infected grapes may be affected.
Identifying mildew on grapes
You can recognize a powdery mildew infestation by the white spots on the top of the leaf (powdery mildew) or the underside of the leaf (downy mildew), which turn brown or gray over time. The vines also turn yellow and become stunted. The symptoms are therefore quite easy to identify on the leaves, but how can you tell whether the fruits are also affected?
- the shell hardens
- the fruits burst (seeds break)
- scattered dark spots on the fruits
Different types of mildew
You can't just tell the difference between true and downy mildew. There are different species of the pest that specialize in one plant. A grape fungus only attacks grape vines and not tomato plants. While powdery mildew can have toxic effects on some leaves, the grape fungus is relatively harmless. Winegrowers also make their wine from infected grapes.
Allergic reactions possible
However, allergic reactions are possible when consumed, which manifest themselves in the following symptoms:
- Stomach problems
- Digestive Problems
- Difficulty breathing
- Rash
Negative consequences of powdery mildew on grapes
Although powdery mildew is not poisonous, an infestation of a winery has indirect he alth consequences. Since mildew is also very common in Germany, many winegrowers would be bankrupted if they destroyed their harvest if the fungus was present. Fortunately, wine made from infected grapes is still drinkable, although it loses considerable flavor. Nevertheless, the rapid spread is forcing more and more farmers to use pesticides, which in turn can cause physical problems in consumers.
