RELACS just released a new project video on replacing copper in plant protection products in organic viticulture.
In the organic vineyard inherited from his grandfather, vintner and owner Márton Ruppert has been cultivating Blue Frankish grapes since 2016. Over the past two years, Márton has been using tagatose to replace copper in the framework of a RELACS project’s experiment.
To better evaluate the effectiveness of tagatose, Márton Ruppert also carried out copper-based treatments in control plantations. According to him, tagatose is effective, useful and can be easily mixed and used in tank mixtures when applied as a powder. Hence, no disadvantage in comparison to common plant protection products with copper content could be found.
In addition to using tagatose, Márton Ruppert implements several other organic practices, such as large row spacing, planting cover crops, and removing unnecessary leaves. This further reduces the number of plant protection treatments on his vineyard significantly.
RELACS’ project partner the Hungarian Research Institute of Organic Agricuture (ÖMKi) produced this video.
