phylloxera

Grafting is the only known effective way thus far of treating phylloxera. The aphid-like insects in question must be treated preventively in the sense of grafting phylloxera-tolerant rootstock (such as Vitis berlandieri, V. riparia, V. rupestris) onto phylloxera-susceptible Vitis vinifera's above-ground parts.
