Often, illnesses arise from poor or improper care. Or pests or garden tools carry it. Fungi can also be transmitted through seeds.
Diseases of cucumbers: treating gray rot
A disease that occurs due to a fungus. And it affects the leaves and stems of the plant. It is transmitted through the air and can affect almost the entire garden. The most favorable environment for the development of rot is very high humidity and low air temperatures. Signs of gray rot: - a very high percentage of wilting of plants in the garden; - shoots begin to rot; - gray spots on fruits, stems and leaves; This disease is dangerous in that it can destroy the entire crop completely, and later spread to nearby crops and trees. Rot hibernates in the ground; therefore, plant damage begins from the bottom. If you notice the appearance of this stroke in the garden, immediately start treatment. Gray rot can be defeated with a solution of copper sulfate, spray all the plants and spill the soil with this solution, then sprinkle the bed with ash. Prevention: - seed treatment; - thorough removal of plant debris; - compliance with the sowing rules.
Diseases of cucumbers: prevention of white rot
White rot is the most common fungus; it is carried around the site by wind or insect pests. Growths begin to form on the infected plant. The upper part of the stem begins to suffer first. The leaves turn white and begin to wither, if you do not take action, the plant will die. Most often, the plant occurs due to sudden changes in temperature and high humidity, if the plants are not treated, you risk being left without a crop. In order for your cucumbers not to be struck by white rot, you need to follow the rules of prevention: - cleaning of vegetable debris; - feeding with complex fertilizers; - decrease in humidity in the garden. If white rot has already begun to spread in the garden, it should be treated. The fungus is very afraid of a mixture of activated carbon and potassium permanganate, I advise you to sprinkle the soil with crushed chalk. In order to secure the planting of the next season, sprinkle the bed with ash in the fall.
Fighting root rot
A fungus that attacks the roots of a plant. Affected roots rot and the plant dies. This disease is very difficult to determine, since the focus of infection is underground, you can only navigate by the state of the plant.
1) Even after watering, the plant looks sluggish.
2) Leaves dry massively.
3) Flowers fall, which means that the ovary is not formed.
4) The leaves are covered with a dark bloom.
5) The bush slows down growth.
It is not only fungus that can lead to the development of root rot. Root rot can be brought in with a garden tool, when watering seedlings with cold water and when planting very deeply. In order to defeat root rot, you need to use a solution of honey, ash and chalk, mix everything in equal proportions and fill it with a liter of water (I take 1 tablespoon of each component). We process the ridged areas.In order to exclude the appearance of this disease in your garden, you should follow the rules: - in very hot weather, weeding is prohibited; - we water the plants only with warm water; - we water the plants only at the root.
Powdery mildew
This disease is provoked by a spore parasite. They can be seen on the leaves of cucumbers as they cause a white bloom. The fungus infects the plant completely. The white bloom formed on the plant gradually begins to darken. The leaves turn black and die. High humidity and frequent temperature changes are very favorable for the development of this infection. Also, the appearance of a fungus can cause an excess of nitrogen fertilizers and not a residual amount of light. In order to cure your plantings, you will need 5 grams of soda and liquid soap, diluted with a liter of water. We carefully spray the bushes with this solution. Another effective measure is to spray the garden with whey. Prevention of the onset of the disease: - water the cucumbers only at the root; - we regularly fertilize the soil with phosphorus; - we remove all plant residues.
Downy mildew treatment
The most common disease of the cucumber garden, which is caused by a group of fungi. The fungus manifests itself on shoots and leaves, with a massive spread, the plant dies. Infected plants can be identified by the brown color of the leaves. There are different ways to treat this disease. Ten drops of iodine must be mixed with a liter of skim milk and diluted with 9 liters of water. We spray plants in dry, calm weather. The second method, we dilute 2 grams of manganese in 10 liters of water and process the cucumber bed. If the fungus has spread throughout the entire area, then chemicals should be applied, there is no other way to destroy the fungus. Prevention: - 2 weeks after planting in the soil, treat the cucumbers with a solution of Bordeaux liquid; - we carefully remove organic waste; - if plants grow in a greenhouse, provide regular ventilation.
Cucumber Diseases: Anthracnose
A fungus that can appear on many horticultural crops. You can understand that the plant is sick by the brown spots on the leaves. The spots become larger and gradually take over the entire plant. The bushes dry out and gradually die. The outbreak most often occurs in mid-May. The main causes of this fungus are: - high acidity of the soil; - insufficiently fertilized soil; - high humidity. You can fight this disease with Bordeaux liquid or 1% colloidal sulfur solution. Also, the bushes can be sprayed with soluble copper sulfate. Prevention for this disease is very simple, regularly feed the soil and water strictly according to the schedule.
Treatment of bacteriosis
A disease caused by three types of fungi. This infection only appears and spreads in hot weather and high humidity. Bacteria enter the soil with poorly treated seeds or insect pests. The disease is very dangerous and can lead to the loss of a significant part of the crop. You can understand that plants are infected by small yellow spots on the leaves and watery spots on the stem. In this case, the fruits begin to deform.
In order for an outbreak of this infection to occur in your garden, you must carefully follow the rules of agricultural technology.
1) Remove all plant residues from the area.
2) Re-plant seeds and soil.
3) Dig deeply into the soil.
4) Do not allow excess water to accumulate in the garden.
Diseases of cucumbers: Rhizoctonia
This fungus spreads not only on the cucumber garden, but also on potatoes and cabbage. Signs of the disease - dry leaves and fruits covered with ulcers, it is impossible to eat and store such fruits. This fungus is excreted only by preparations containing chemistry of the substance.

With a mosaic disease, the leaves turn brown and begin to roll up, both leaves and fruits suffer from this disease. This fungus overwinters very well in the soil. This disease usually affects damaged or weak seedlings. It is worth noting that this virus cannot be treated; therefore, infected plants must be immediately eliminated. But if you follow agricultural practices, then the outbreak of this virus can be avoided.
1) Thorough disinfection of garden tools.
2) Treatment of seeds by replanting.
3) Timely weeding.
4) Destruction of insect pests.
In autumn, the soil must be treated against fungi and viruses.
Prevention of olive spot
It is possible to understand that the plant is infected by the brown spots on the leaves, which eventually become covered with a white bloom. This virus infects the entire plant completely; the harvest from the infected bushes cannot be expected. Infection of the plant usually occurs through the soil or through poorly treated seeds. To treat this fungus, you can use a weak iodine solution or milk whey. If you apply fertilizers and weed the beds on time, the disease can be prevented. Now by knowing the precautions you can prevent diseases and infections of cucumber and treat them correctly.
