Experiments were carried out at the Upytė Experimental Station of the Lithuanian Institute of Agriculture. They were designed to investigate the occurrence of fungi on the seeds of various oil flax cultivars during harvesting and storage as well as to test the effectiveness of chemical agents intended for their control. The following potential mycotoxin-producing fungi were identified at a genus level: Alternaria spp., Aspergillus spp., Fusarium spp., Penicillium spp., their incidence (%) on seeds was measured and efficiency of fungicides against these fungi was estimated.
