Pearl Glands on a new shoot from a Chardonnay vine
What appear like insect eggs have appeared on the new shoots of the vines, mainly the Chardonnay. In fact these are what are known as Pearl Glands which are tiny balls of vine cells which result from seepage of stomata on the shoots. They often appear on the stems,tendrils, petioles or leaf veins on vigorous vines in warm humid conditions.
Pearl Glands are harmless but may attract ants as a food source.
