Goal. To develop methods for short-term forecasting of the seasonal development of powdery mildew on grapevine. Methods. The research was conducted using correlation and regression analyses. Results. A close correlation relationship (R² = 0.9956) was established between the sum of active temperatures (SAT) and the dynamics of development of the causative agent of powdery mildew (E. necator) under the conditions of the Southern Steppe of Ukraine. A mathematical model for forecasting epiphytotics
