The most resistant varieties of open ground cucumbers

When choosing cucumbers for open ground, every gardener tries to find varieties that are not only fruit-bearing, but also resistant to various diseases. This crop is often subject to fungal and viral diseases, which is accompanied by loss of yield, plus the plant itself also dies. To help gardeners understand a little about this complex problem, in this article we will look at common diseases of cucumbers and try to identify the most resistant varieties.

Review of common cucumber diseases

Any diseases of cucumbers are expressed by characteristic spots on the plant, and sometimes even on the fruit. One of the reasons is nature itself. Sudden changes in temperature from the coolness of the night to the heat of the day are detrimental to the plant. Another reason, without knowing it, is the person himself. By watering beds with cucumber seedlings with cold water, the gardener creates favorable conditions for the development of various diseases.

Let's look at the most common diseases of cucumbers and briefly familiarize ourselves with control methods:

  • powdery mildew easy to identify by the white spots on the front side of the cucumber leaves. At first they are small, but over time they grow quickly, affecting all the leaves. You can save the plant at the initial stage of stain development. To do this, prepare a solution of two parts chalk plus one part colloidal sulfur and treat all the plantings in the garden bed. After 7 days, and then at such intervals until cure, the plants are treated with a solution prepared from 10 liters of water and 15 g of sulfur. Instead of sulfur, you can add 100 g of liquid soap and 7 g of copper sulfate to the same amount of water.
  • Downy mildew, scientifically called peronosporosis, is expressed on the leaves of the plant by similar spots only yellow. Sometimes a gray or purple coating 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 entire plant, from the stem near the ground to the upper leaves. It is easy to identify a cucumber disease by its white, slippery coating. This often occurs due to untimely removal of old foliage. When the first signs are detected, the plants are immediately sprinkled with dusty lime or chalk. You can treat it with copper sulfate by dissolving 5 g of powder in 1 liter of water. The affected parts of the plant only need to be removed, there is no other way out.
  • Root 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.Preventive watering with a solution of the drug “Previkur”, every 14 days, will help prevent the appearance of rot on cucumbers.
  • Anthracnose is expressed by yellow spots turning into sores on the stems and foliage of the plant. Over time, the fruit itself is affected by pinkish ulcers. For treatment, Bordeaux mixture 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 damage to the fruit by rotten sores of a brown hue. The control methods are the same as for anthracnose.
  • Mosaic It mainly affects young cucumber foliage, making it wrinkled and brown in color. Such plants cannot be cured; it is better to destroy them. The disease can be prevented by preventing open ground. Copper sulfate is added once a year in the fall or spring.
  • Olive spot covers the fruits 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 and increase in diameter. This disease is more common in greenhouses due to a lack of fresh air with little ventilation. Less common on open ground plants. To control cucumber plantings, they are treated with the drug “Fundazol” or a 1% solution of Bordeaux mixture.

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.
