Abstract
The application of copper-based fungicides has led to the problematic accumulation of copper in the soil of many European vineyards. In this work, we tested the effectiveness of downy mildew control strategies that considerably reduce the amount of copper, through the application of other non-toxic compounds. The study took place in three different regions of Catalonia, by combining smaller and larger-scale trials for two growing seasons. Although variations among experiments were detected, the treatments used here may reduce the applied copper content by up to 77 percent. The cooper reduction-strategies, which alternated standard copper application of copper oxychloride with applications of products based on Equisetum arvense L., or with applications of products with heptagluconic acid (an alternative formulation with a very low-rate of copper), provided the most consistent protection against downy mildew. Moreover, these treatments reduced copper inputs by 63 and 47 percent as compared to conventional treatments based on repeated applications of copper oxychloride. This work underlines the possibility of reducing the amount of copper applied to control downy mildew in Mediterranean vineyards, through the use of newly-developed formulations.
期刊介绍：
The European Journal of Plant Pathology is an international journal publishing original articles in English dealing with fundamental and applied aspects of plant pathology; considering disease in agricultural and horticultural crops, forestry, and in natural plant populations. The types of articles published are :Original Research at the molecular, physiological, whole-plant and population levels; Mini-reviews on topics which are timely and of global rather than national or regional significance; Short Communications for important research findings that can be presented in an abbreviated format; and Letters-to-the-Editor, where these raise issues related to articles previously published in the journal. Submissions relating to disease vector biology and integrated crop protection are welcome. However, routine screenings of plant protection products, varietal trials for disease resistance, and biological control agents are not published in the journal unless framed in the context of strategic approaches to disease management.
