Efficiency of Zeolite as Alternative Product for Controlling Downy Mildew (Plasmopara viticola) in Table Grape

Downy mildew is a disease caused by  obligate parasite Plasmopara viticola on grapevine worldwide.  Chemical fungicides are widely used for the control of downy mildew. However, the use of copper based fungicides has been limited by European Commission regulation since 2002, and pathogen- resistance to some of systemic fungicides have been reported. Therefore, the development of environmentally friendly and sustainable products to protect against downy mildew in table grape is necessary. In this study, we tested several formulations of zeolite in semi-field and field experiments to evaluate their efficaciouses to control downy mildew. The most effective zeolite products on grape yield and quality were investigated in two locations. This study could be help the development of a novel environmentally friendly product, not only yield loss and also sustainable control of downy mildew on grape. The potential of zeolite to control of downy mildew on grape have been demonstrated for the first time.
