Abstract
This article provides information on the spread, development and damage of fusarium disease, which occurs in cabbage vegetable crops (white cabbage, cauliflower, broccoli, red cabbage, savoy cabbage, Chinese cabbage) and the use of biological preparations against this disease. Healthy and vigorous seedlings were obtained when fusarium disease was treated with a titrated suspension Orgamica F of 1∙108 CFU (colony forming unit)/ml, and the number of diseased seedlings was 0.6–1.0%. It was noted that 0.9-1.3% of seedlings from seeds treated with a titrated suspension of the preparation 1∙104 CFU/ml were infected with fusarium disease. Also, in the experiment, a option that showed high biological efficacy against white fusarium disease: Orgamika F biopreparation 3 times, ie with a suspension of 1∙108 CFU/ml titer per seed before sowing, 2% suspension of the biopreparation (2∙106 CFU/ml titration suspension). It is recommended to apply the biopreparation to the seedling root before planting and 15 days after planting in the field with a suspension of 0.25% concentration (2.5∙104 CFU/ml titration) under production conditions.

Summary
Cole vegetables (white cabbage, cauliflower, broccoli, Chinese cabbage, Beijing cabbage, and savoy cabbage) have a special place. In 2017, the total area planted cabbage in the world was about 2.5 million hectares, and cabbage and cabbage vegetables were grown 71.45 million tons [1, 2]. Cabbage is the third largest vegetable crop in the country after tomatoes and onions [3, 4], of which in 2017 the production of cabbage reached 904,000 tons [1, 2]. The homeland of cabbage is the Mediterranean coast, which belongs to the category of very ancient crops [5]. The composition of cabbage is not rich in nutrients, it is a source of minerals, vitamins and especially vitamin C [6]
