In the protection of Polish grape-vine only Euparen 50 WP is recommended against gray mold (Botrytis cinerea) therefore the authors tried to find some other fungicides. Studies were conducted on Pannonia Kincse variety cultivated under foil. The following fungicides were used: Dithane M-45, Euparen 50 WP, Ronilan 50 WP, Rovral 50 WP and Sumilex 50 WP. The fruit infection on the protected shrubs was always lower and the fruit yield was significantly higher than from the control shrubs. Mankozeb can not be used because the tolerance limit was exceeded 15 times. The maximum residue of Euparen and Ronilan suggests that these compounds can be use in grape-vine protection
