An important disease is rhizoctonia, this disease is better known as black root rot. Many options can act as a causative agent. Initially, this disease manifests itself as follows: in young white roots, small areas begin to turn black, this happens in a fairly short time. Over time, black spots will appear on the roots, which will also spread very quickly. The roots themselves will become fragile over time. Diseased plants themselves are distinguished by very poor fruiting. When brown rot is already formed, then this is a sure sign that the plant will soon die. Plants are susceptible to this disease at any period of their growth, but the greatest danger of the disease is young strawberries. Rot can occur throughout the growing season.

It is very important not to plant strawberries in their original place; such a return is permissible after at least four years. It is not recommended in any case to fertilize the soil with poor quality or rotted compost. A preventive measure will be spraying in the autumn period with the help of a drug called Ordan. In spring, trichoderma should be applied through a drip irrigation system.

Gray rot is considered a very common disease. Damp warm weather is the most favorable conditions for the development of such a disease. Densely planted and poorly ventilated areas are susceptible to this disease on a larger scale, and long-term cultivation of strawberries in the same place also has a beneficial effect on the course of the disease. Weeds, plant debris and already diseased berries will become the centers of this infection. The most affected are berries. Brown spots with a fluffy bloom of gray appear on the berries. Sick berries will dry out and mummify. As for the stalks and ovaries, they will be ringed with brown spots, which will dry out over time.

You should choose extremely healthy seedlings; airing and contact of the fruits with dry films will help reduce the risk of this disease. As a preventive measure, spraying in the spring with drugs called a switch or desoral is also suitable. This spraying should be repeated immediately after flowering in especially rainy years. It should be noted that the spores of this disease are well tolerated with wind and raindrops. Therefore, it is very important to remove the already affected plant parts from the site in a timely manner.

Horse late blight is very often known as reddening of the axial cylinder of the root. This disease becomes noticeable in May-June on especially warm and dry days. The disease is characterized by the sudden wilting of the entire plant. Actually, as it is already clear from the name, the disease begins with reddening of the axial cylinder of the root. Over time, the roots will begin to die off. Diseased leaves acquire a bluish-reddish tint. The affected leaves will then begin to wilt. This pathogen is perfectly preserved in the soil as spores. As for the main sources of this disease, they will be diseased planting material and the soil itself.

Preventive measures will be a careful selection of seedlings, which must be completely healthy, without the slightest sign of any disease. Compliance with the rules of crop rotation will also become very important. The correct watering regimen and adherence to the proper amount of fertilizers are very important to prevent the occurrence of such a disease. In addition, the soil should be treated with trichoderma through a drip irrigation system. As soon as you see the first signs of this disease, you should treat the beds with appropriate drugs, for example, metaxil. Treatment must be carried out with a drip irrigation system.
