Major diseases occurring on flax crops in Lithuania are caused by Fusarium spp., Colletotrichum lini Manns et Bolley, Polyspora lini Laff. et Peth., Septoria linicola (Speg.) Gar. They can spread through seed, especially when the seed material does not meet quality standards. Microscopic fungi of other species can be found on flaxseed as well. Chemical seed treatment is one of the ways to control disease agents. When treated seed is sown, the seed treaters affect the indigenous micro-biota of the soil. The trial was carried out at the Upyte Research Station of the Lithuanian Institute of Agriculture in 1999. The tested seed treaters are registered for cereals in Lithuania. Our experimental results suggest that chemical treatment of flaxseeds is an efficient method to control seed-borne diseases. The microscopic fungi on seeds and roots of seedlings were analysed at the Institute of Botany. The data on the effect of seed treaters on the diversity of pathogenic fungi of flaxseed and seedlings, and the impact of treatment on the seedling infection are discussed in this paper.
