Cucumbers can suffer from viral, bacterial and fungal diseases. They need to be able to identify them by the very first symptoms: infections spread quickly, so that delay can destroy most of the crop or the entire plant as a whole.

Viral diseases

A common symptom of viral diseases is a change in the color of the leaves in certain areas. Over time, the spots merge, and the sheet dries and deforms.

The white mosaic shows itself as light spots in the form of stars. They grow rapidly, and soon only veins remain green on the leaf. The symptom of a speckled green mosaic is light, wrinkled areas that appear near the veins. The infected bush does not develop well, its yield drops sharply, the fruits are deformed and change color.

Aphids are the most common carriers of the virus. The grains themselves can be contaminated, therefore, before sowing, it is recommended to warm them up at a temperature of + 65–70 ° C for 2–3 hours. If there are only a few infected leaves on the plant, they need to be torn off and burned. With extensive infection, you will have to get rid of the entire bush - treatment in this case is impossible. After gardening, you need to disinfect the equipment.

To prevent disease, it is important to observe the timing of crop rotation, to prevent thickening of crops and the proximity of weeds, to remove plant residues in a timely manner and to destroy aphids.

Fungal diseases

Fungal spores most often affect cucumbers due to sudden changes in temperature, watering with cold water, and high air humidity. It is recommended to immediately remove diseased leaves and shoots, and treat the plant with fungicides.

White rot covers the leaves, stems and fruits of the plant. A white or light gray slippery coating appears on them.

Copperhead shows itself as blurred copper, brown or black spots on all parts of the plant. Infected leaves dry out. On fruits and stems, the spots look depressed.

Black spot begins with the appearance of dark spots on the leaves, which then increase, acquiring a brown tint. There are concentric formations inside these spots.

Powdery mildew is a common fungal disease. Read more about the causes of powdery mildew and how to combat it in the article Its main symptom: the appearance of a light powdery coating on the stems and leaves. Gradually, it captures an ever larger area, and if you do not take action, it kills the plant.

Bacterial diseases

Most often, bacterial diseases develop in high humidity.
If the leaves begin to wither sharply and sag on the petioles, becoming covered with spots, and a thick whitish liquid is released from the stems, the cucumber is most likely affected by bacterial wilting. For treatment use "Fitolavin" and "Pharmayod".

Due to wet rot, the lower leaves wither, a large number of barren flowers are formed, the fruits are deformed, and a brown mass appears inside them. In the heat, the turgor of the stems is noticeably reduced. There is no cure; diseased plants must be disposed of.

Angular spotting is very dangerous: it spreads quickly and kills the plant in a short time. It manifests itself by the appearance of brown, quickly drying spots on the leaves and fruits. The source of infection is contaminated seeds and plant debris. Treatment is carried out using fungicides: "Acrobat", "Quadris" and others.

To prevent bacterial infections, it is important to disinfect the soil and equipment, avoid mechanical damage to plants, get rid of parasites in a timely manner, and process the seeds before planting.

Processing cucumbers with iodine and brilliant green. What is the use and why should it be done?

Why are these simple drugs good? They are completely harmless both for cucumbers and for us who love to eat these vegetables. And, you see, this is a big plus today, when vegetables are grown on an industrial scale using a huge amount of various chemicals, from feeding seedlings at an early stage to processing an already finished crop for longer storage. We, however, will replace most of these pesticides with iodine and brilliant green. And, they can be applied in different ways.

Protecting cucumbers from root rot

If this disease has affected your cucumbers, then curing the plant is already very problematic. So, it is better not to allow it to appear at all. Iodine with greens will help you. We drip 10 drops of greenery on a standard, that is, a 10-liter bucket of water, and pour our cucumbers with this brilliant water when the crop has already been harvested from them. So, next year you will not allow the occurrence of this disease. You can sprinkle the plant with iodine - for 10 liters of iodine water, we take 10 milliliters. Both of these methods are preventative and work pretty well.

Another option to prevent root rot on cucumbers is to lubricate its stem (from the ground about 10 centimeters in height) with greenery or iodine, which are diluted 1: 2 (that is, for 1 part of either greenery or iodine, water is taken 2 parts). If you grow cucumbers vertically, then this method of protecting them is most convenient. For 2 treatments, at an early stage of the disease, the fungi are guaranteed to die.

Powdery mildew protection

From this disease, the leaves on the cucumbers turn yellow, and then wither. To protect cucumbers from this scourge, you can insist on rotten hay. It is placed in a small barrel, half of this barrel is filled with water and we let our protective agent brew for 2-3 days. Then we filter it, and spray the cucumbers 3 times with a week break.

Zelenka protects cucumbers well from downy mildew. Pour water (10 liters) into a bucket, add 10 milliliters of greens and a couple more components - urea (50 grams), and whey or ordinary milk (2 liters).

Processing cucumbers with such a composition should be carried out 3 times per season. When the cucumbers bloom, we process them the 1st time, and the 2nd and 3rd already at weekly intervals.

And, here are two useful videos, where you will be told a few more ways to use iodine and greens for processing cucumbers. Watching video # 1.

Advantages and disadvantages of the method

Using garden whey has strengths and weaknesses. Benefits:

  • the soil is enriched with nutrients and amino acids
  • rich productivity
  • does not harm health, therefore personal protective equipment is not required
  • culture develops better
  • feeding solution is prepared quickly
  • can be used to process various vegetables
  • rapid maturation of the compost
  • used for pest control.

It is allowed to water the whey cucumbers during fruiting, since there is no harm to health. For this reason, vegetables are suitable for consumption the very next day after fertilization.

The disadvantages include:

  • short-term effect
  • the whey needs to be diluted because it makes the soil acidic
  • not resistant to precipitation.

The drink does not last long, so you need to process cucumbers constantly.

What work should be done in the garden

Gardening is a favorite pastime of many people, but in order for fruit trees and berry bushes to enjoy the abundance of fruits in autumn, use an inexpensive but effective pest control tool. Which one? All the same iodine!

For destruction fruit rot prepare a mixture: 10 ml of iodine in a bucket of water. Spray trees one month before harvest, then repeat the same procedure 3 days later.

Harmful aphid it will evaporate if the bushes and trees are sprayed with such a solution: 1 ml of iodine per 1 liter of milk, process once every 10 days.

Take a closer look at the plants in the country during the period of fruit setting. If this process is not active enough, then they need iodine feeding. Can be sprayed or watered under the root: 10 ml of a trace element per bucket of liquid.

Features of outdoor care

Care during fruiting consists in the formation of a bush, timely fertilization, watering, loosening the soil and hilling.

Secrets of proper watering

The surface of the leaves of cucumbers is thin, therefore, with a lack of moisture, they lose their turgor. Because of this, the first emerging ovaries fall off, which leads to a decrease in yield. Excessive moisture is also harmful, increasing the plant's susceptibility to disease.

Watering is carried out with water at room temperature, preferably settled or rainwater. Regimen: at least once a week, 3-5 liters of water per plant.


With the appearance of 2-3 true leaves, the bushes spud. This is done in order to build up additional roots and increase the endurance of the culture.

For your information. The stronger the root system of cucumbers, the faster the ovaries form.

When and what to fertilize

Improper fertilization is bad for plants. They feed it mainly with organic matter. Use mullein or chicken droppings diluted 1:10 with water. For each bush, 1-1.5 liters of fertilizer are consumed. Plants are fed twice a month. If the weather is hot, this is done more often.

The culture responds well to the alternation of complex mineral and organic fertilizers. For the introduction of mineral dressings, special preparations are used, for example, "Crystallin", "Solution" or "Kemira". It is also effective to feed the plants with an ash solution (a glass of ash for 10 liters of water).

On a note... Experienced gardeners feed the cucumbers with cow's milk diluted with water in a 1: 2 ratio.

Protection against diseases and pests

Diseases and pests make it more difficult to grow cucumbers outdoors. Diseases lie in wait for the culture throughout the growing season. In the open air, the infection is transmitted by air.

The most common diseases of cucumbers:

Root rot can destroy the entire crop. The first signs appear immediately after planting plants in a permanent place. When the daytime temperature rises, the foliage wilts, and at night it regains its elasticity. The lower part of the stem of the bushes becomes brown. At this time, they do the following:

  • the fungicide "Hom" or the biological product "Bactofit" is introduced into the soil
  • spud stems for the development of new roots
  • for the resistance of plants to diseases, the bushes are treated with Effekton.

Anthracnose affects the whole plant: whips, leaves and even fruits. Yellow spots spread through the foliage, pink ulcers appear on the fruits, the stems begin to dry out, the vegetables become unusable.

The sooner the plant is cured, the more chances it is to save it. To overcome anthracnose, the bushes are treated with 1% Bordeaux liquid.

Powdery mildew appears due to cool weather (+ 15-20 ° C) with high humidity. At first, the disease manifests itself as a white coating on the leaves. In the future, the foliage dries and turns yellow.

Cucumber bushes are treated for powdery mildew with an aqueous infusion of mullein (1:10). If the disease is already progressing, the bushes are sprayed with a solution of ferrous sulfate (5%).

Plants are often attacked by aphids, which complicates the care of the crop. In damaged bushes, leaves wither and turn yellow, buds and ovaries deteriorate. Insects reproduce quickly, they can destroy an entire garden in just 10 days.

For the fight, a soap-ash solution is used. In 1 liter of water add 2 tbsp. l. ash and laundry soap diluted in hot water. This tool is used to wash the leaves and stems of cucumbers. The procedure is carried out in the morning, and at noon a covering material is thrown over the plants, protecting the leaves from sunburn. After five days, the event is repeated.

On a note. To scare away pests and feed weak plants, the soil under them is sprinkled with wood ash.



“My husband and I bought exactly our land plot when we saw how luxurious plums grow on it. The former owners advised us to use the "Aktara" product to take care of them, it helps to eliminate many pests and diseases. I recommend using it only with the help of a special sprayer, so it will "work" more efficiently. "


“I always thought that fruit plants grow on their own and do not require absolutely any maintenance. As it turned out, I was very deeply mistaken in this. The first problem for me was the attack of aphids, because of which I was practically left without a crop. I recommend treating the aphid plum with chemicals immediately after the snow has melted. In order to avoid problems with pests in the future ”.

Plum is one of the most delicious and healthy berries, it is loved by adults and children. To get a good harvest in summer, starting in early spring, spray the tree against pests and garden diseases, follow proper care and preventive measures. Then nothing prevents the plant from creating a lot of juicy fruits.
