Additions to the sunflower rust development model

The life cycle of sunflower rust in the conditions of the Russian Federation has been supplemented, the harmfulness (up to 40% of losses) and the biological threshold for starting fungicides’ treatment (3-5% of the damaged plants) are indicated. It is noted that for the economic efficiency of fungicidal treatments against rust, it is necessary to strictly use the recommended rates of water volume.
Keywords: Sunflower, sunflower rust, Puccinia helianthi, harmfulness, fungicides, PPP water volume, pathogenesis, biology of the rust.
