Hello everyone, I know it is a busy time for you are, so I will make this quick. With grape root borer adult activity coming to a close here in Georgia, I wanted to get your input on this tricky pest. Below is a link to a short questionnaire about grape root borer management. If…

We collected our first grape root borer adults today in one of our pheromone traps in Lumpkin County, 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 at the…

While infestation of wine…

Many of the fungicides utilized for Botrytis management are no longer efficacious due to resistance development in this fungus. Now is a great time to collect Botrytis samples for fungicide-resistance testing. While the funds last, Botrytis resistance testing is free for wine grape producers in most of the Southeast (Alabama, Arkansas, Georgia, Louisiana, North Carolina,…

A colleague forwarded me the following learning opportunities in viticulture and enology, as particularly related to Bordeaux cultivars. Given that some Bordeaux cultivars are widely planted throughout the southeastern US, these “short courses” may be of interest to some UGA Extension Viticulture Blog subscribers. Bordeaux Sciences Agro has created short courses in English for…
