What is molecular ampelography?
Modern genotyping and DNA analysis techniques have revolutionised ampelography. They allow varieties to be distinguished without waiting for the plants to develop.
Mechanical weeding and required technical skills
Mechanical weeding in the row is not simply a question of replacing one technique by another.
10 questions and answers about plant cover in the vineyard
What are the advantages of plant cover? How do the plants compete with the vines? Which species should I choose?
What are the new avenues of research in system experimentation?
It is crucial to design innovative viticultural systems to respond to the challenges facing winegrowing
The work of IFV shows that although certain alternatives to herbicides, such as glyphosate, are possible and even effective, they have technical and economic consequences for farms.

Confined spraying in viticulture
Confined spraying is an opportunity for winegrowers because it combines efficiency and respect for the environment.
Diversity of spraying techniques
Measurement of the quantities of spray deposits obtained on the EvaSprayViti test bench clearly show that high-performance spraying techniques exist which represent significant progress compared to the most commonly used techniques.
Rosé wines: impact of storage conditions in tank on the polyphenol composition and color
Color of Rosé wines is an important criterion for consumer choice. This color depends on the concentration of anthocyanins and also of other pigments derived from them.
