Consequences of climatic changes, undoubtedly, will be reflected in distribution of harmful organisms, their injuriousness and will demand development of new approaches in plant protection. Over the last 10 years, the spread of cereal crop diseases in the Northwest Russia has been monitored. The purpose of researches is to find new diseases in the Northwest region of Russia. Disease progression was mainly monitored 3 or 4 times during the growing season, from germination to crop maturity. As a result in this region the new diseases were found. In 2005-2007 the causal agent of yellow leaf spot Pyrenophora tritici-repentis was found on wheat. Fusarium graminearum historically has two areas in Russia： the North Caucasus and the Far East. However, since 2003 F. graminearum appeared on the territory of the North-West of Russia. Septoria tritici became the main pathogen of wheat in the North-Western Region.. In 2013 Ramularia collo-cygni was found in Arkhangelsk region. These observations suggest that global warming of climate leads to an expansion south species pathogen to the north regions of Russia.展开更多
