My customer has a commercial greenhouse and has a problem with these wrinkles in her cucumbers. The wrinkle has a hollow spot on the inside. They taste fine. Another gardener told us they thought it came from a tendril that has wrapped it during growth. The customer says it happens VERY early right when the baby fruit just forms. The other picture is a fruit with a stripe on the peeling. Others do not have it.Want to make sure it is not a virus or a fungus.
Laclede County Missouri cucumbers
Here are the major descriptions:
Viruses cause a yellowish, mottled pattern to appear on the leaves of the plant. The disease progresses, ruining the fruit of the cucumber by giving it a bitter flavor.
Mildews are fungal diseases that cause leaves to wither and drop prematurely. If severe enough, fruit may grow poorly.
Wilts are untreatable, fatal fungal diseases that cause cucumber plants to wilt and die. Symptoms may include white mold on the vines, stunted growth and discolored roots.
Leaf spot diseases such as Anthracnose, Alternaria leaf spot and Cercospora leaf spot are fungal diseases that cause spots to appear on the leaves of the cucumber plant, sometimes leading to stunted growth and lower-quality fruit.
We have had the coldest April on record followed by the hottest may on record. Some areas of Missouri are experiencing drought conditions and others are just low on water.
We are seeing lots of atypical growth on all plants this year.
I seriously doubt that either of these two concerns are a virus or fungus.
