Phylloxera is an insect that destroyed the vineyards of the Old World at the end of the 1800s. This problem was solved by grafting the European Vitis Vinifera with American rootstock.
Over the past years we have seen Phylloxera infecting the leaves of the vines starting to cause some damages to the quality of the grapes. You can see the front and back of an infected leaf in the photos.
We could have used, as many others do, chemical products to fight the pests, but we have undertaken a more natural direction using fertilizers stimulating the vines to produce their own defenses allowing the vines to stop and overtake the Phylloxera attacks.
