  • Greetings everyone, If you have not already experienced it, any day now, your ears will be met with the screams of millions of periodical cicadas. While every year we experience the evening songs of the annual cicadas, this year we are privileged to hear the musical musings of cicadas from the Great Southern Brood. This…

  • In case you haven’t heard the news, I wanted to give everyone a quick update on the fact that as of November 2, 2023, chlorpyrifos use on food crops is no longer banned. The 8th U.S. Circuit Court of Appeals overturned the EPA’s decision to revoke tolerances of chlorpyrifos on food crops. The official ruling…

  • 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 wine grapes reach approximately 15…

  • Greetings everyone, I hope this post finds everyone well. I am part of a new working group that is attempting to improve pest management through mating disruption technologies. However, before we can do that, we need to better understand growers’ needs and perception of mating disruption. As such, if you have a little extra time,…

  • It is Japanese Beetle Season

    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 new plantings. Older, established vines…

  • 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 you are unfamiliar with grape…

  • 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 Brix, the grapes become attractive…

  • 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 females will lay their eggs…
