Heterodera avenae and Heterodera latipons are widespread on cereals in Bulgaria and mixed populations are encountered. H. avenae populations reach their highest point on barley after ten years cereal monoculture. The two‐field crop rotation maize/cereals keeps the population at a low level. H. avenae has been found on most cultivars of wheat and barley cultivated in Bulgaria. The author had detected two previously unreported hosts: Agrostis capillaris and Cynosurus cristatus. The most appropriate conditions for infection on cereals occur in April. Nematode development starts in April and finishes in the first half of June. Nematophthora gynophila parasitizes about 20% of the cysts, while Catenaria auxiliary and Lagenidiaceous fungi do so to a lesser extent.
