With the increase in sugars, veraison kicks off the period to start managing drosophilid flies (e.g. spotted wing drosophila (SWD)), which can considerably help suppress sour rot in your vulnerable grapes. The drosophilid flies are active nearly year round in these parts, but near veraison, as the brix levels in…

The time is upon us once again. Japanese beetles are showing up in vineyards around the state. In large enough numbers, Japanese beetles can be a severe pest of grapes during the summer, feeding mainly on foliage and (thankfully) rarely on the berries. More problematic is Japanese beetles feeding on…

We are within a few weeks of the anticipated initial emergence of grape root borer (GRB) adults here in Georgia. If you are planning on implementing mating disruption as a management tactic for GRB and you haven’t deployed your pheromone dispensers/ties, now is the time to get those distributed. If…

With veraison upon us, it is time to start planning your spotted wing drosophila (SWD) management to help suppress sour rot in your vulnerable grapes. 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…

We collected our first grape root borer adults today in one of our pheromone traps in White and Lumpkin Counties, Georgia. This means that the adults have started to emerge from the soil out of their pupal stage. For the next few weeks the adults will emerge, mate, and the…

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…
