While the funds last, Botrytis resistance testing is free for wine grape producers in most of the Southeast (Alabama,…

We have experienced yet another moderate…

I just wanted to alert everyone that spotted wing drosophila (SWD) management timing is approaching soon. The SWD flies are active nearly year round in these parts, but near veraison as the brix levels in wine grapes reach approximately 15 degrees Brix, the grapes become attractive (and thus susceptible) to…
