Bacteriosis of cucumbers: causes, symptoms and treatment of the disease

Cultivation is not complete without treatment against diseases. Bacteriosis of cucumbers is common with any method of cultivation. Summer residents recommend that preventive treatment be carried out correctly in order to avoid loss of yield. There will be no difficulties with this, even for a beginner.

Favorable conditions for the development of the disease

High humidity is a harbinger of the intensive spread of bacteriosis. Also, high temperature affects its active development.

The vector is seed, plant debris, wind and rain.Insect pests and the person who prunes can also transfer pathogens. All instruments must be disinfected. Rain washes away bacteria from a diseased leaf to a he althy one. The wind carries the dry remains of the cucumber tops, thereby spreading the bacteria further.

Oversaturation of the soil with nitrates will lead to the development of bacteriosis of cucumbers. Since bacteria feed on nitrites. The disease also develops with dense plantings.

The virus penetrates through open wounds and stomata, injured roots. When it enters the fruit, it settles in the seeds. Favorable temperature for the life of bacteria is + 25-27 ⁰С, and humidity is 80-85%.

Symptoms by which the disease is recognized

To find out that cucumbers are affected by this disease is simple, just carefully examine the appearance of the plants. The spread of the disease begins with the cotyledon leaves, they are covered with angular spots. The first days they are yellow, then they turn brown.

If there is high humidity, then mucus begins to flow from the back of the leaves. As soon as it gets dry, spots dry up, turn white and crumble. Holes form in their place. Over time, only the veins of the leaf remain, everything else dies and crumbles.

With a more severe lesion, the effect of bacteria on 70-90% of the entire green mass is observed. Cucumber fruits are also susceptible to the virus, they become deformed and lose their taste.

Then the plant slows down and begins to shed its leaves. Fruiting stops. If you delay treatment, the shoots will die.

Consequences of plant damage

Disease angular spotting of cucumber leaves - bacteriosis, can cause great damage to plantings. With a slight lesion, the plant gives 50% less yield than a he althy bush. If the situation is difficult, the lashes begin to die, and then the whole plant.

If the development of the disease is not stopped in time, the gardener risks losing most of the bushes, and significantly reduce the yield of the remaining plants.

A plant is affected by a disease at any stage of the growing season.

Not only the yield of plants is decreasing, but also the presentation and shelf life of the vegetable is deteriorating.

Prevention against infection

Treatment of a disease is a complex process, it is easier to carry out preventive work. This will save the harvest, time, strength and nerves of the summer resident. Prevention:

• Choosing a landing site. The site should be located on a hill and sunny side. Being in the sun, the bacterium dies within an hour. Shaded beds, not heated by the sun's rays, are a favorable environment for the reproduction of bacteria.It is best to avoid drafts and strong winds.
• The location of the bushes. Vertical fastening of the plant's lashes is recommended. Oxygen access is provided, the lashes are less in contact with the ground.
• Hilling and loosening. Access of oxygen to the roots.
• Water. I use only warm water.
• Feeding. A he althy plant resists disease more easily. Enough 2-3 dressings with the following composition: 20 g of superphosphate, 7 g of urea, 20 g of potassium s alt, 2 g of manganese, 4 g of copper sulfate.
• Processing. Use folk methods of combating bacteriosis. Chemicals settle in cucumbers. Preparation Hom: 40 g per 10 liters of water, sprayed bushes. Another drug Energen: 5 ml per 10 liters of water.
• Cultivation in protected ground. The greenhouse is good because the level of humidity in it is regulated. In addition, it is difficult for insect carriers of the disease to enter the enclosed space. The temperature inside is stable for 24 hours.
• Selection of disease-resistant seed material. Breeders strive to develop a variety that will be immune to the disease. At this time, these are hybrids: Masha, Lesha, Murashka, Octopus. Varieties Competitor, Nezhensky 12, Far East 6, 12, Delicious.
• When self-collecting plant seeds, only he althy cucumbers are selected.
• Removal of plant residues. After harvesting, all plants are recommended to be burned or taken out of the site, the bacteria in the ground die.
• Disinfection of the greenhouse. Treatment of walls, beams, supporting structures with special solutions.
• Seed dressing. Before planting, it is recommended to treat the planting material with Fitolovin 300,TMTD.
• Autumn digging. In winter, the soil is plowed deep, the remaining bacteria die.

How to deal with the spread of the disease?

Each summer resident has his own methods of struggle. Chemicals work best, but they are harmful to he alth. They are used before flowering and the formation of ovaries in plants. Often, folk methods of treating a disease are used, which each vegetable grower chooses according to the effectiveness of the impact:

• Growing in a greenhouse, summer residents raise the temperature, and ventilate the room, reducing air humidity.
• Spraying with 0.5-0.7% solution of Bordeaux liquid or copper oxychloride.
• All severely diseased plants, leaves and lashes are destroyed.
• Fungicides and insecticides are used in the complex. For example: Aclectic and Byleton or Aclectic and Farmayod-3.
• Onion decoction. Husk 0.7 l jar, pour 10 l of water, boil for 1 minute. Insist 12-15 hours. After strain and let stand. Then spray the plants with a solution of 4 liters of water per 1 liter of the resulting infusion. It is recommended to water the soil as well.
• Chemicals that summer residents use strictly according to the instructions: Kuproksad, Abiga-Peak, Fitolavin.

The opinion of vegetable growers agrees on one thing, it is best to carry out preventive treatments in a timely manner than to treat cucumbers for bacteriosis. The consequences of the disease can be very serious, loss of 80% of the crop. In addition, the bacteria remain in plant debris, winter well and will begin to progress with renewed vigor next season.

Preparing the site in the fall, timely fertilization, removing weeds and loosening and watering, these are the main agricultural practices that will save the spread of the disease.
