Many gardeners, wanting to grow an early crop on their plots, build greenhouses where tomatoes and cucumbers ripen much earlier than their neighbors in the open ground. And while growing vegetables in greenhouses, people try to protect the plant from adverse external factors, acid rain, the scorching sun, etc. Perhaps the plants will be protected from something under a film cover, but do not forget that in the protected ground for bacterial diseases ideal conditions are created. Most often, tomatoes and cucumbers are grown in greenhouses. It is known that over the past decade, the yield of the most popular vegetable - tomato - has been declining rapidly. Tomato diseases in the greenhouse and on the open ground do their dirty deed. This article will discuss diseases and methods of controlling dangerous bacteria that infect tomatoes.
Disease tomato in the greenhouse. Types and methods of treatment
Climate change, the widespread use of fungicides led to the fact that bacteria have adapted to many natural factors and all kinds of chemicals. And as a result - the widespread occurrence of bacterial diseases that affect plants. In addition, many tomato diseases have mutated, and now it is quite difficult to distinguish one disease from another. In order to successfully deal with the "enemy", it is absolutely necessary to determine its pathogens. Tomato diseases in a greenhouse develop more intensively and affect almost all plants.
Mosaic
With this disease, the leaves of the plant are deformed, their color changes. Tomatoes look depressed. They give a low yield. In order to get rid of the virus, the affected plants are burned. And to prevent the disease, the seeds are soaked before planting in a weak solution of manganese. Planted seedlings are also watered with potassium permanganate solution. Treating a tomato for disease usually involves spraying plants. With this disease, tomatoes are sprayed with skim milk. To do this, add a liter of milk and a teaspoon of urea to ten liters of water. Sprinkle seedlings every three days.
Leaf mold and brown spotting
Diseases affect the leaves and trunk of the plant. Brown spots with a gray coating appear on the underside of the leaf. Subsequently, the leaves fall off, and the plant dies. The cause of the disease is waterlogging of the soil, as well as watering with cold water at low temperature. If brown spotting struck tomatoes, then the first thing to do is to reduce soil moisture and adjust the temperature regime. Affected plants must be sprayed with copper chloride (40 g per 10 liters of water). To prevent the disease after harvesting, treat the plants, as well as the soil and walls of the greenhouse with a solution of copper sulfate. The next year, tomatoes cannot be planted in this soil.
Phomosis, or brown rot
Diseases of a tomato in a greenhouse are very often similar to plant diseases on the open ground. Phomosis refers to this disease. This fungal ailment appears only on the fruits in the form of brown spots near the stalk. Fruits do not have time to ripen and fall still green. To prevent the disease, it is necessary to avoid overmoistening the soil and not to feed the plants with fresh manure. If phomosis attacked tomatoes, it is necessary to treat the soil with foundationazole.
Prevention
In order for diseases of the tomato in the greenhouse (photos are presented in the article) not to destroy your hopes for a good harvest, buy seeds only in specialized stores. And do not forget about preventive measures.
