Phytopathological situation in crops of spring wheat varieties in Belarus

Monitoring of phytopathological situation in crops is the basis for biological justification need protective measures, allowing to obtain a yield close potentially possible. The results monitoring spring wheat varieties are presented paper. Studies were carried out 2019–2021 laboratory phytopathology and experimental field Institute Plant Protection. Standard methods used during work. main criteria assessing degree plant infestation disease development (%) area under process curve (AUDPC, conditional units). Analysis state showed that growing season crop affected by diseases vegetative generative organs: root byroot rots, powdery mildew, leaf ear septoriosis, pyrenophorosis, brown rust, fusariosis ear. Root rot, spot disease, spikelet among dominant annually present crops. Variety differences incidence factor influencing emerging crop. Cultivation resistant reduces risk epiphytotics. According sum infectious loads experienced plants whole period vegetation, evaluated ranked ascending order: Lyubava (60,5 %), Slavyanka (61,9 Sudarynya (66,9 Laska (71,3 Darya (83,9 %). studies allow give preference most interesting varieties, based on available opportunities ensure proper level protection against diseases.
