Potato plague is a disease that is known to many gardeners. It can destroy whole yellow or potato yields. In addition, it produces spores that can survive in the ground or plant remains. During mild winters, they can maintain germination capacity for several months. For this reason, it should be taken care of the beds so that the soil is ready for cultivation.
The first step to be made is Cleaning the bed of infected plants. We have to do it as soon as possible, because if the leaves dry, they will fall and spread throughout the garden with the wind.
The sick parts of the plants are best thrown into a tight container so as not to spread the plague. We can also use the spread foil. It is important that the infected elements of the specimen are not thrown on a pile, which moves loose to other places. Remember not only to get rid of fallen leaves and twigs with potato plague, but also about the removal of the roots.
Additionally poles that maintained, should be thoroughly disinfected. The same applies to garden tools. If the cultivation was supported on the strings, it should be thrown away immediately.
After cleaning the beds, they should be properly taken care of to be suitable for cultivation next season. It is recommended Making solarization of soil, i.e. covering a moist substrate with transparent polyethylene foil for about 4 weeks. Under the influence of the sun, the temperature in the upper layer of the substrate can rise to about 50 degrees Celsius, thanks to which it will destroy most spores.
In the event that there are no high temperatures anymore, use the evaporation steaming, putting its nozzle under the foil. In addition, it is worth focusing on podlon. In this case, e.g. white mustard, buckwheat, Facelia or Bobik will be perfect. These are plants that secrete alleopathic compounds that limit the development of pathogens.
What’s more, their roots can effectively improve the structure of the substrate, and also allow them to increase the biodiversity of microorganisms that will compete with the potato plague. Podlons are best done from August to September.

In addition, it is a good idea The use of compost and well -fermented manure. It is these elements that will introduce soil microflora, which will naturally stop the development of diseases. This treatment is performed by the thermal method.
However, in spring, before planting plants, it is worth using microbiological preparations that work against pathogens, as well as colonize the rib and limit the germination of spores.
