Botrytis cinerea is a fungal pathogen that causes significant damage to table and wine grapes. Various chemicals are
intensively sprayed to protect grapes from this fungal pathogen; however, this practice can significantly increase production
costs and lead to residue risks during the production season. This study investigated the effectiveness and minimum effective
application doses of commercial plant protection products containing different active ingredients in various formulations
used to combat B. cinerea. The effectiveness of three licensed plant protection products (fenhexamid, cyprodinil, and
pyrimethanil) against a B. cinerea isolate was compared comparing these products, sold in various package sizes and at
different prices, in controlling B. cinerea was investigated, assessing whether there was any difference between them. The
study was conducted by incubating B. cinerea isolates in Petri dishes of 9-cm diameter containing potato dextrose agar.
The diameter of the fungal colony was measured after 3-, 5-, and 7-day incubation periods. The results showed that the
three active ingredients were effective at the recommended dose of 1000ppm and at doses as low as 80ppm. However,
significant decreases in their effectiveness were detected at much lower doses of 40 and 20ppm. The active ingredient
pyrimethanil was the standout fungicide in terms of efficacy rates, package size, price stability, and time between the last
application and harvest. The results of this study can help reduce production costs and residue risk.
