Ernst Ruhl from Geisenheim on Phylloxera
This show was published 30 September 2011
We ask Professor Ernst Ruhl from the Geisenheim Grape Breeding Institute to explain how phylloxera attacks grape vines.
Ernst explains how phylloxera, an aphid, feeds on both leaves and the roots of grape vines exclusively. It's the aphid's ability to feed on the roots that is the problem and causes the vines to suffer water and nutrient deficiencies which weaken the plant until the roots and plant eventually dies. We hear about the life cycle of phylloxera above and below the ground and the conditions in which it thrives.
