Choosing cucumbers for open ground, each gardener tries to find varieties that are not only fruitful, but also resistant to various diseases. This culture is often exposed to fungal and viral diseases, which are accompanied by loss of yield, plus the plant itself also dies. To help gardeners deal with this complex problem a little, we will consider in this article common diseases of cucumbers and try to determine the most resistant varieties.

Overview of common cucumber diseases

Any diseases of cucumbers are expressed by characteristic spots on the plant, and sometimes even on the fruits. One of the reasons is nature itself. Sharp changes in temperature from night coolness to daytime heat are destructive to the plant. Another reason, unknowingly, is the person himself. By pouring cold water on the beds with cucumber seedlings, the gardener creates favorable conditions for the development of various diseases.

Let's look at the most common diseases of cucumbers and take a quick look at the methods of struggle:

  • Powdery mildew is easily identified by the white specks on the front of the cucumber leaves. At first, they are small, but over time they grow rapidly, affecting all the leaves. You can save the plant at the initial stage of the development of spots. To do this, prepare a solution of two parts of chalk plus one part of colloidal sulfur and treat all plantings in the garden. After 7 days, and then with such frequency until cure, the plants are treated with a solution prepared from 10 liters of water and 15 g of sulfur. Instead of sulfur, 100 g of liquid soap and 7 g of copper sulfate can be added to the same amount of water.
  • Downy mildew, scientifically peronosporosis, is expressed on the leaves of a plant with similar spots of only yellow color. Sometimes a gray or purple bloom may also appear on the back of the leaf. The drug "Ridomil" or "Ordan" can prevent such diseases. They are used according to the instructions included in the package.
  • White rot spreads throughout the plant, starting from the stem near the ground, ending with the upper leaves. It is easy to determine the disease of a cucumber by a white slippery coating. This often occurs due to the untimely breakdown of old foliage. When the first signs are detected, the plants are immediately sprinkled with dusty lime or chalk. Can be treated with copper sulfate by dissolving 5 g of powder in 1 liter of water. The affected parts of the plant need only be removed, there is no other way out.
  • Basal rot develops on the lower part of the plant, affecting the stem and foliage. The cause of the cucumber's malaise is the cold water used from the well for irrigation. The plant begins to acquire a brown tint and gradually withers. Preventing the appearance of rot on a cucumber will help preventive watering with a solution of the drug "Previkur", with a frequency of 14 days.
  • Anthracnose is expressed by yellow spots, turning into ulcers, on the stems and foliage of the plant. Over time, the fetus itself is affected by ulcers of a pinkish hue. For cure, Bordeaux liquid with a consistency of 1% or a solution of 40 g of copper oxychloride per 10 liters of water is suitable.
  • Angular spot or another name - bacteriosis. The disease is expressed by brown spots on the foliage of the plant and the defeat of the fruit with rotten sores of a brown hue. The methods of struggle are the same as with anthracnose.
  • The mosaic mainly affects the young foliage of the cucumber, making it wrinkled with a brownish brown color. Such plants cannot be cured; it is better to destroy them. The disease can be prevented by the prevention of open ground. Copper sulfate is added once a year in autumn or spring.
  • Olive blotches cover the fruit with rotten sores. Spots of a similar brown color appear on the stems and foliage of the plant. After three days, the spots begin to turn black, increasing in diameter. This disease is more common in greenhouses due to lack of fresh air with low ventilation. Less commonly manifests itself on plants in open ground. To combat the planting of cucumbers, they are treated with the drug "Fundazol" or 1% solution of Bordeaux liquid.

Even the most disease-resistant varieties can be affected by one of the ailments. To get a good harvest, it is important to identify the disease at the initial stage and remember about prevention.
