Cucumbers are tasty and healthy vegetables that can be grown in your garden or in a greenhouse.
But sometimes cucumbers can suffer from various diseases that appear as yellow spots on the leaves.
Yellow spots on cucumbers can be caused by various reasons.
Spider mite
This is a small insect that feeds on plant sap and leaves yellow spots on the underside of leaves.
Spider mites love dry, hot climates and can reproduce and spread quickly.
To combat spider mites, you need to spray plants with insecticides or infusions of garlic, onions or tobacco.
Cucumber mosaic virus
A viral disease transmitted by aphids or infected seeds, cucumber mosaic virus causes yellow spots or streaks on leaves and fruit, as well as deformed and reduced yields.
To combat the cucumber mosaic virus, you need to destroy aphids, use healthy seeds, and adhere to sowing and harvesting dates.
Downy mildew, or false powdery mildew
It is a fungal disease that thrives in cool, humid climates.
Downy mildew causes yellow, angular spots on the upper side of leaves that then turn brown and dry out.
A grey or purple coating appears on the underside of the leaves. To combat downy mildew, plants should be sprayed with fungicides or infusions of nettle, garlic or chamomile.
These are just some of the causes of yellow spots on cucumbers. To avoid these diseases, you need to follow the rules of planting, watering, fertilizing and caring for cucumbers.
You also need to regularly inspect the plants and promptly remove infected parts or entire plants. This way you can keep your harvest healthy and tasty.
