Juicy leaves and roots of beet are fine nutrient medium for causative agents of various diseases. Diseases of beet can destroy from 20 to 70% of harvest. That it has not occurred, it is necessary to take special measures.
Beet disease korneed
Korneed ruins sprouts and shoots of plant. The stalks of shoots affected with disease blacken and become thinner, sprouts of beet perish, without having managed to reach the surface of the soil.
The disease appears from behind the increased acidity of the soil, lack of aeration, bad processing of the earth. Korneed – disease of beet which can remain in the soil, collects on the remains of plants, extend through seeds.
For fight against disease of fall it is necessary to bring limestone in sour soils. In the spring before landing of plants the land should be cultivated pine forest solution. Not to allow emergence of korneed, you regularly loosen beet row-spacings, burn all plant debris in the fall.
Alternation of cultures on one soil will help to avoid many diseases.
Beet disease fomoz
Fomoz call also heart-shaped decay. The disease affects scapes, leaves and root crops of beet. At first on leaves and scapes light sites with black dots – mushroom sporonosheniye appear. Further fomoz gets into root crop and develops in it. Sick root crops have the black, juicy and solid struck fabric inside. In storage time on these sites, emptiness with white mycelium can appear. The pica of the development fomoz reaches during winter storage, most often at this time it also comes to light. In certain cases fomoz can be not infectious disease, the lack of pine forest of the soil can cause its emergence. If the disease has appeared from behind it, the plant badly grows and develops, at it begin to perish young greens. Further root crops begin to suffer, in them decay of black color is formed.
For storage for the winter select the healthiest and strong beet as sick root crops can infect all harvest.
For fight against disease it is necessary to introduce in due time to the soil boric fertilizers, to burn plant debris in the fall. Soaking of beet seeds before landing in 1% solution of boric acid helps to prevent emergence of fomoz.
Decayed
Fuzariozny decay usually strikes beet at the beginning of summer. At the plants affected with this disease the lower leaves begin to wither, scapes blacken and on root crop there are cracks filled with white raid. Brown decay appears on tail part of root crop and also on scapes of beet and on the surface of the soil around it. Brown decay appears from behind excess soil moisture and high content of nitrogen in it. To protect beet from decay, it is necessary to lime soils, to loosen row-spacings, to introduce fertilizers with the maintenance of pine forest, to struggle with wreckers and to destroy all remains of plants.
