The influence of four pre-crop plant species on the occurrence of arbuscular mycorrhizal fungal (AMF, <i>Glomales, Zygomycetes</i>) spores, mycorrhizae and <i>Phialophora graminicola</i> (Deacon) Walker associated with roots of field-culuvated <i>XTriticosecale</i> Wittmack cv. Malno was investigated. The pre-crop plant species were <i>Hordeum vutgare</i> L., <i>Lupinus luteus</i> L., <i>Pisum sativum</i> L., and <i>Vicia faba</i> v. major Harz. Most spores and species of AMF were found when <i>XTriticosecale</i> was cultivated following <i>P. sativum</i>. Prior cropping with <i>L. luteus</i> caused the occurrence of the lowest number of spores among <i>XTriticosecale</i> roots. Mycorrhizal colonization of <i>XTriticosecale</i> was highest when planted after <i>P. sativum</i> and lowest when grown after <i>L. luteus</i>.
