First Paragraph: Borner is the first classified rootstock with complete Phylloxera resistance. The total resistance to Phylloxera is due to the hypersensitive reactions of the plant cells. The attacked cells immediately become necrotic and are cut off by a sub-layer of cells, preventing feedback of the insect and any secondary infection.
