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.
