Spray Drift Awareness Issue 1 2010 (Barossa Grape and Wine)
In previous seasons (e.g. 2008-2009) grapevines in the Clare Valley experienced extensive damage to grapevine productivity and yield as a result of 2,4-D spray drift. Whilst 2,4-D products are not registered for use in vineyards, it can be used in other agricultural systems. The product however is strictly regulated in terms of timing i.e. it is banned each year between September 1 and April 30 and restrictions apply for droplet size and wind speed.
