White Spots on Cucumbers
If you’ve ever grown cucumbers, you may have noticed small, white spots appearing on the skin of your fruits. These spots are called “cucurbit powdery mildew” and are caused by a type of fungus. The fungus appears as a white powdery substance on the leaves and stems of cucumber plants, and can eventually spread to the fruit.
While cucurbit powdery mildew is not harmful to humans, it can cause your cucumber plants to lose their leaves and produce fewer fruits. If left unchecked, the fungus can kill your plants entirely.
So what can you do if you find cucurbit powdery mildew on your plants?
The best course of action is to remove any affected leaves or stems and dispose of them properly. You can also try spraying your plants with a fungicide designed for powdery mildew, but be sure to follow the instructions carefully.
With proper care, you can still enjoy a bountiful crop of cucumbers even if some of them have white spots!

How Do You Get Rid of White Spots on Cucumber Plants?
There are a few things that can cause white spots on cucumber plants. One is powdery mildew, which is a type of fungus. It thrives in warm, humid conditions and can be difficult to control.
Another possibility is downy mildew, which also loves warm, humid weather. This one is caused by a different type of fungus and can be just as hard to get rid of as powdery mildew. Finally, white spots could be caused by cucurbit aphids.
These tiny pests suck the sap out of plants and can cause all sorts of problems, including white spots.
If you’re dealing with white spots on your cucumber plants, the first thing you need to do is figure out what’s causing them. Once you know the culprit, you can take steps to get rid of the problem.
If it’s powdery or downy mildew, you’ll need to use a fungicide specifically designed for those fungi. Be sure to follow the directions carefully and apply it at the right time of day (usually early morning or evening). If aphids are the issue, there are a few things you can do.
You can try spraying them with water or an insecticidal soap solution. You can also attract natural predators like ladybugs into your garden to help control the aphid population. Whatever method you choose, make sure you keep an eye on your plants and act quickly if you see any more white spots appearing!
Why is There White Spots on My Cucumber Leaves?
Cucumber plants are susceptible to a number of diseases that can cause white spots on the leaves. One of the most common is powdery mildew, which is caused by a fungus. It thrives in warm, humid conditions and can spread quickly from one plant to another.
Other diseases that can cause white spots include cucurbit leaf crumple virus and cucurbit downy mildew.
Powdery mildew usually starts out as small, circular spots that turn white or grayish as the fungus grows. The leaves may eventually become distorted and covered in a thick layer of powdery spores.
Cucurbit leaf crumple virus causes similar symptoms, but the leaves will also start to crinkle and curl up. Cucurbit downy mildew produces fuzzy gray or white patches on the tops of leaves, with yellowing and wilting eventually occurring on the affected foliage.
To prevent diseases from causing white spots on cucumber leaves, it’s important to practice good garden hygiene.
This means removing any infected plants as soon as possible and disposing of them properly (do not compost them). Avoid overhead watering, which can help spread fungal spores, and water only at the base of plants. Use a sharp hoe or knife to remove weeds regularly, since they can act as hosts for disease-causing organisms.
Finally, make sure to choose disease-resistant varieties whenever possible.
