Leaf spot and other diseases seem to hang around Maryland. This year I am being more vigilant in disease control. In as little as 3 days, diseases can take hold. The last few days have been warm, wet, and muggy.
Two cucumbers have a leaf spot. I should have addressed it 5 days ago but I was still in denial. I wanted it, the spots, to be burns from my sulfur spray. It wasn't.
This is how you tend to the disease:
- Nip the leaves off right at where the stem meets the leaf
- Remove flowers or damaged fruit
- Leave only disease free leaves
- Put down newspaper
- Spray plants and paper with sulfur spray or your choice
I remove the leaf at the leaf stem. You could remove the leaf and stem at the vine. I prefer leaving some stem to make it harder for bugs to get to the stem. This is just a preference not a fact. There is good chance the stem has spores too. SO your choice.
