A preventive approach helps to limit the risk of developing vine diseases (mildew, powdery mildew, etc.).
In the absence of chemical treatments, we have few solutions to keep the vine healthy, but many plants contain active extracts that benefits the natural defenses of the vine.
The key to success is to choose, depending on the climate, the right combination of:
- The use of small quantities of Bordeaux mixture and sulfur to fight against powdery mildew and mildew
- The spraying of herbal teas such as wicker, field horsetail, nettle and biodynamic silica preparation
- The control of the vine vigor by disbudding or aeration of the grapes by deleafing
This is a work of observation and close protection that the winemaker performs on a daily basis.
