The results of the study on the effectiveness of such preparations as 5-aminolevulinic acid hexyl ester and Fitovital for incrustation of winter rape (Brassica napus) seeds are presented in the article. It has been established that their use has positive influence on seed field germination, plant development in autumn, and increases yield of this crop under relatively favourable conditions in autumn and winter period on average by 9.3-10.8%. However, in extreme conditions of overwintering, use of these preparations did not protect winter rape crops against death. Dressing seeds of winter rape with the preparation ET-ALA (hexyl ether 5-aminolevulinic acid) in the dose of 0.15 g / l had a positive impact on the development of the plants in autumn, increasing the germination of seeds in an average of 3.1%, root length and plant height before winter period - by 12.1 and 16.3%, respectively. The similar effect on plant growth and development and was provided by fitovital (1.2 l / ton). However, in extreme conditions of overwintering the use of these preparations failed to protect the crops from destruction of winter rape.
