Wheat is the main product in 53 countries, including in our country. The leading producers of wheat grain in Kazakhstan are Akmola, Kostanay and North Kazakhstan regions. The virulence of previously weakly pathogenic pathogens, for example, spotted wheat leaves caused by many imperfect fungi from the genera Septoria and others, has increased. The purpose of the study is to conduct phytosanitary monitoring of the spread and development of spring wheat septoria and to study the influence of weather conditions on the development of the disease. The technique is generally accepted in phytopathological studies. In 2018, favorable weather conditions were elaborated for the development of Septoria on spring wheat. A high correlation in all studied varieties was observed between the degree of manifestation of the disease and the number of days with precipitation > 1 mm. 2019 was an unfavorable year for the development of septorious spots, the disease was depressed. A close negative correlation was found on all wheat varieties between the degree of development of the disease and the number of days with precipitation > 1 mm. Phytosanitary monitoring of the spread and development of spring wheat septoria is required annual monitoring to conduct a complex of preventive and protective measures to limit them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
