The pest Drosophila suzukii also causes significant damage to grapevine berries. Kaolin-based products and biostimulants were tested in an experiment to reduce the development of Drosophila suzukii and the development of sour rot, while the effect on grape quality parameters was also investigated. Surround, building kaolin, NovaFerm Orion, NovaFerm Sirius and Hycolat were tested on Riesling, Traminer and Palava varieties between 2023 and 2024. In terms of reducing damage to Drosophila suzukii berries, the most effective application was Surround (3%, 5%). Of the biostimulants, NovaFerm Orion and Hycolat were the most effective. The same products also showed good efficacy in point of reducing the development of sour rot. In view of the effect on grape quality parameters, the most significant negative impact was on pH values. Rheinriesling and Traminer showed an increase in pH values compared to the untreated control. pH is a very important parameter in the context of grape processing and fermentation.
