Abstract

<abstract abstract-type="main" id="ps3917-abs-0001"> <title>Abstract</title> <sec id="ps3917-sec-0001" sec-type="section"> <title>BACKGROUND</title> <p id="ps3917-para-0001">In France, viticulture accounts for 20% of the phytochemicals sprayed in agriculture, and 80% of grapevine pesticides target powdery and downy mildews. European policies promote pesticide use reduction, and new methods for low‐input disease management are needed for viticulture. Here, we present the assessment, in France, of Mildium^®, a new decision support system for the management of grapevine mildews.</p> </sec> <sec id="ps3917-sec-0002" sec-type="section"> <title>RESULTS</title> <p id="ps3917-para-0002">A 4 year assessment trial of Mildium has been conducted in a network of 83 plots distributed across the French vineyards. In most vineyards, Mildium has proved to be successful at protecting the crop while reducing by 30–50% the number of treatments required when compared with grower practices.</p> </sec> <sec id="ps3917-sec-0003" sec-type="section"> <title>CONCLUSION</title> <p id="ps3917-para-0003">The design of Mildium results from the formalisation of a common management of both powdery and downy mildews and eventually leads to a significant fungicide reduction at the plot scale. It could encourage stakeholders to design customised farm‐scale and low‐chemical‐input decision support methods. © 2014 Society of Chemical Industry</p> </sec> </abstract>
