Abstract

Summary Attempt of application of mixture of bacteria Propionibacterium freudenreichii spp. shermanii and Lactobacillus rhamnosus in the control of selected seed-borne cereal diseases in the field conditions was undertaken. The experiments were performed in the seasons 2009/2010 and 2010/2011. The seeds used in the experiments were naturally infected with Pyrenophora graminea and Ustilago nuda (winter barley) as well as contaminated with teliospores of Tilletia caries (winter wheat). Tested bacteria were the most efficient in the control of barley leaf stripe. Soaking the seeds during 15 minutes in a mixture of bacteria suspension resulted in the reduction of barley loose smut incidence. Efficacy of tested bacteria in control of common bunt varied between years of experiments. The obtained results indicated the need for further investigations.
