Botrytis and Berry Splitting - UPDATE 22/2/2011

Since the weekend we have been busy monitoring for weather damage in vineyards.

High rainfall events during ripening commonly causes the skin of grape berries to split - fortunately it seems damage has been limited with most vineyards escaping with minimal splitting. Typically less than 1% damage has been seen.

Riesling, Chenin Blanc, Pinot Gris and Sauvignon Blanc are the main concern where some botrytis has been seen to develop in the last 72 hours (above). We have also seen one vineyard of Shiraz in Blewitt Springs and one vineyard of Grenache that is developing botrytis bunch rot.
