Can you eat diseased potatoes?
Two serious potato bacterial diseases, ring rot and brown rot are regulated by EU law. The diseases do not make potatoes dangerous to eat for humans or animals, but they can seriously affect yield and quality of the potato crops.
What is the most harmful disease of potato?
Potato blight (also known as late blight) is a disease caused by a fungus-like (Oomycete) organism (Phytophthora infestans) that spreads rapidly through the foliage and tubers of potatoes in warm, wet weather, causing collapse and decay.
What does potato disease look like?

PVY symptoms include yellow, light green and dark green “mosaic” patterns on leaves, leaf drop, brown or black (necrotic) line patterns often on veins or shoots, necrotic lesions on leaves and stems, rugosity (wrinkling), yellow flecking, stunted growth, death of growing points, tuber cracking and tuber necrosis.
Can potato warts make you sick?
After plant emergence, when stolon tips or tuber eyes become infected, resultant disease processes can render the potato tuber unrecognizable and unfit for human consumption. However, it should be noted that the potato wart fungus is not a human pathogen and poses no threat to human health.

It is difficult to control its spread since the fungus can survive in the soil on plant residues without a living plant.
Which of these parasite is found on potato plants?
Plant-parasitic nematodes are a significant factor limiting potato production and tuber quality in several regions where potato is produced. Overall, parasitic nematodes alone cause an estimated annual crop loss of $ 78 billion worldwide and an average crop yield loss of 10–15%.
Do potatoes grow fungi?
Causes of Fungus on Potatoes
The appearance of potato fungus happens mainly due to infected seed potatoes or planting in infected soil. Most potato fungi not only attack potatoes, but can survive (though may not kill) on other plants in the nightshade family such as tomatoes and peppers.
