Environmental sustainability, linked to fungicide treatments, leads to a quest for innovative answers, which
are closer to the environmental ones. In this context we included our experimental activity, developed in the
harvests of 2013, 2014, 2015 and 2016, which is looking for innovative defense solutions in viticulture. The
work was based on the study of a new low-impact product, which contains peroxides, for the defense against
fungi pathogens in grapevine, especially downy mildew (Plasmopara viticola). Some tests were done at the
experimental farm at the University of Udine “ A. Servadei”, while others were carried out in vineyard in
some farms of Northern Italy. In general, the preliminary results confirmed the possibility of total protection
against downy mildew in vineyards with the new product at low impact for some varieties under certain
climatic conditions; however, we should consider the possibility of managing certain situations with an
integrated strategy. Given the absence of product residues and non-interference in winemaking of any residual
peroxides, it can be assumed an application also in the final stages of the phytoiatric defense season.
According to the results, further trials are needed to respond to situations of risk by optimizing the control
strategies in each specific condition.
