We are still detecting grape root borer adults in north Georgia. This means that the adults are still active, with females potentially still laying eggs. While we are getting a little late for chemical control, if you have more than 35 days before harvest, you can use Lorsban 4E* (chlorpyrifos).This is currently the only insecticide registered…

August is on the horizon, and you might be interested in the latest outlook for the next month. Unfortunately, I don’t see any big change in the pattern for the next month. Cooler and wetter conditions are expected to dominate the weather this week as the stream of atmospheric moisture that has been causing flooding…

I was at a muscadine meeting in Americus, GA earlier this week (Thursday), and I made comment on how I have never really observed significant crown gall on muscadine grapes in Georgia. I scheduled a muscadine grape visit with a producer near Ellijay, GA the next day, and I can now say that I have…

We collected our first grape root borer adults today in one of our pheromone traps in north 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 base…

I’ve been getting this question a lot in the last couple of weeks, as farmers and everyone else get inundated by repeated rounds of thunderstorms that develop over the afternoon hours and grow in the late afternoon heat. I’ve gotten almost three inches of rain in the last…

We have been receiving multiple grape samples with black rot in our diagnostic clinic. Only one or two infected grapes can provide a vast number of spores for secondary infections of clusters going forward. Prevalent rainfall has made control difficult. The disease cycle will slow as grapes mature, but fruit can still be infected till…

The Schnabel lab at Clemson University is still offering free testing to help identify resistance problems in the gray mold pathogen Botrytis cinerea from small fruits. The test covers the most important FRAC codes for gray mold control. As grapes approach veraison, Botrytis may start to become a problem as clusters tighten and/or in low ventilated areas…

We are starting to see diseases pop up on both European vinifera and hybrid grapes. For some of these, such as anthracnose and Phomopsis, much of the initial infection occurred much earlier. The goal now would be to prevent secondary spread — especially to developing clusters. Relative downy mildew, Sarah Campbell (UGA grad student) reported…
