Abstract

Modern tobacco protection follows the principles of sustainable agricultural production and supports the use of environment-friendly methods. Trichoderma harzianum T22 is the most powerful biocontrol agent. The aim of our research was to study its ability to control the causing agents of damping off disease in tobacco seedlings. Trianum P is biological fungicide which contains spores of T. harzianum T22. It was applied in a rate of 15 g/10m2 through three modes of application and with two additional treatments by the time of planting. Investigations were made in biolaboratory and in seedbeds, with natural infestation. The biofungicide was applied by storing the seed in suspension 48h before sowing, fungicide application over the soil and first application 15 days after sowing. All variants in seedbeds were set up with and without herbicide. In the biolab tests, treatment of infested soil was included. Generally, the best results in the control of damping off were achieved in variants where the seed was kept in the product (with and without herbicide-in seedbeds). The poorest results were obtained with the fungicide first application 15 days after sowing. It can be concluded that T. harzianum T22 is biocontrol agent which can be used in protection of tobacco seedlings from the damping off disease. Biological product Trianum P has a good perspective in sustainable tobacco production. Keywords: Trichoderma harzianum T22, Trianum P, damping off disease, intensity of attack
