Development of a method and a device for pest control in viticulture

As part of the joint R&D project between Kaiserslautern University of Applied Sciences, the Rural Area Service Center (DLR) Rhenish Palatinate and the company ANSEROS Klaus Nonnenmacher GmbH (Tübingen-Hirschau, DE), an ozonide formulation and concentration was developed and tested in laboratory, greenhouse and field trials between 2018 and 2021. The focus was on investigating the effectiveness of the treatment against the powdery mildew pathogen (Erysiphe necator) and other vine pathogens. In addition, the influence of the treatment on the microbiome in the vineyard as well as wine analytical and sensory parameters were taken into account. The formulation of ozonated oleic acid (V1/250, LIQUENSO® Oxygenate) used in the field trial had a concentration of 0.8% (v/v) in water, produced with the OXY400 device from ANSEROS Klaus Nonnenmacher GmbH (Tübingen-Hirschau, DE) (patented in Europe (EP 3 478 072 B1). A preventive treatment supplementing the conventional treatment of the vines showed significant efficacy against E. necator. The formulation developed proved to be only weakly damaging to the predatory mites.
