One of the most common diseases in fruit and vegetable crops is late blight, or as it is also called late blight. The defeat of this defect is especially common on the fruits of tomatoes and potatoes

Almost every gardener is familiar with this trouble firsthand. There are many methods of combating this disease: among them, modern chemical processing drugs and folk remedies are equally good and popular.

In addition to tomatoes and potatoes, phytophthora can often be found on eggplants, zucchini and peppers. Among the berries, strawberries are most susceptible to such a nuisance. Many summer residents are interested in methods of protection against late blight and means of combating an already formed disease. But for this, you first need to understand what this disease is in general and how it manifests itself in cultures. Among the people, late blight is also often called brown rot. The defect itself negatively affects the entire plant, except for the roots.

Small spots on the stems and petioles indicate the presence of this disease in the fruit. Most often, these spots are elongated and often merge in several places. As for the leaves. Here, the disease also manifests itself in spots, but their shape is usually irregular, and the color resembles a gray-brown hue. A favorable condition for the development of late blight is warm weather with high air humidity. If the plants are not treated, then the inflorescences will begin to turn black, and the rest of the components of the culture will rot and dry out.

On the fruits themselves, late blight also manifests itself in a special way. Areas damaged by the disease are covered with hard spots located under the skin of the tomato and have a brownish tint. To the touch, the tomatoes themselves will initially be hard, but due to the effects of the disease, they will eventually become very soft. During the ripening of the tomato, the process of the dynamic development of the disease itself continues.

But not all tomato varieties are at risk of being infected with late blight. Some types of tomatoes are resistant to this disease. Among them are ground tomatoes, Berry, Grand, Gaia and others. It is in the power of the summer resident himself to protect the crop from unpleasant consequences with the help of preventive measures and other means.

In the first case, you can start choosing from those tomato varieties that are not afraid of late blight. In addition, it is necessary to correctly and competently carry out crop rotation. And the crops themselves are best grown in greenhouses and greenhouses, protecting them from the effects of atmospheric influences.

On the site itself, mulching of the land should be carried out in time. In no case should the plantings themselves be dense. It is also important to always monitor the normal moisture intake of the plants. Do not allow drought or too wet soil. Another condition in this situation is the harvesting of unripe fruits so that they ripen under the supervision of the summer resident. Regularly, it is necessary to remove the leaves located below so that they do not reach the soil level.

Late blight occurs, primarily due to high humidity levels. Protecting plants from fog and rain is very difficult, but you can try to plant tomatoes in beds with a slightly raised level. Tomatoes planted on the ridges provide excellent ventilation of the bushes. There will also be sufficient sunlight in here. Rain water will drain without stagnating next to the stems.

There are many folk methods of dealing with late blight, but only a few of them are popular among summer residents. For example, a combination of garlic and iodine, prepared in the same solution for spraying plants, perfectly helps to overcome late blight. There are 200 g of chopped garlic per liter of water. The solution is insisted for a couple of days, after which filtration takes place and another nine liters of water and iodine are added. Tomatoes should be sprayed with such a preparation about three times a month.

Another effective way to protect fruits from disease is a dairy product consisting of 100 ml of milk and a liter of water. You can add a couple of drops of iodine to this proportion. As a result, in addition to treating and fighting the disease, the drug will help accelerate the ripening of fruits.
