Classic Downy Mildew On Cucumber

If I were ask for a photo that would show me what downy mildew on a cucumber looks like I would use this photo. This is a classic case of the disease known as Downy Mildew on cucumbers. Short of spraying with Daconil ever 7-10 days from the time it sprouts out of the soil until the time it dies, the only alternative, especially here in Florida, is to grow downy mildew resistant cucumbers. They may still get it but it will take longer. Dasher II and Indio are only two cucumbers on the market right now that show any sign of being resistant. Go to “Vegetable MD” on your search engine and look for “cucumber diseases.” There will be a matrix showing all of the varieties on the market and those that resistant to a particular disease.
