Abstract
The effect of 5% urea application was tested in different regions of Poland.
The leaves were treated at the start of the leaf drop period.
In Dabrowice fallen leaves were dipped in 5% urea suspension.
Perythecia production was checked at the time of first significant ascospores discharge.
Significant reduction of perythecia was found in these places where 5% urea was applied.
Perythecia on treated leaves were poorly developed in comparison to untreated leaves.
