Application of the biopreparation ‘Orgamika F’ against fusarium disease of cabbage and other cole vegetables
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∙10 8 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∙10 4 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∙10 8 CFU/ml titer per seed before sowing, 2% suspension of the biopreparation (2∙10 6 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.
