Hail Damage - UPDATE 24/9/2009


Some hail damage has been seen in McLaren Flat. Fortunately most of the district was spared from damage.

Leaf botrytis can develop in vines that have been damaged by earlier hail and wind – as shown above. This can be common in seasons where we have windy and wet weather in spring. Further rain increases leaf botrytis infections, while dry conditions help heal it up. Leaf botrytis is very easy to monitor for because it is easy to see. Many growers worry because of its obvious nature. The good news is unless the leaf botrytis spreads onto the vine stem or inflorescence no crop is lost. Monitor closely for spread.
