Q&A – What is this white fuzzy stuff on my cucumbers?
Question:
What is this white fuzzy stuff on my cucumbers? The leaves are wilting. It’s on most of the new blossoms.
Answer:
This looks like a fungal disease called gummy stem blight. It can be treated with Chlorothalonil or a copper based or sulphur fungicide. This disease can kill the plant if left untreated. The viewer stated the leaves were wilting, which is not a good sign for this plant. It might be best to pull it out and try again.
