Guido Schnabel, Brett Blaauw and Phil Brannen Late frost has hurt many varieties in South Carolina and Georgia this year. The varieties that escaped the frost, the late bloomers with high chill requirements, still may have fruit and will probably go on a regular spray program, even if chill requirements were not met and a…

Hurricane Ian will probably move relatively quickly through Georgia, but I fear it will have substantial winds as it moves through. Depending on the path, it may cause damage to peach orchards through the Coastal Plain and mid-Georgia area. I hope we all weather the storm well, but I do fear there will be orchard…

Shane Breeden, a graduate student in the Plant Pathology Department, established a trial to review this premise in an O’Henry planting at the UGA Horticulture Farm.…

Frequent summer rains generally increase the risk of green fruit rot. If inoculum is present during the green fruit stage and if long wetness periods occur (30…

There is another series of fungicide options that should also work for the cover sprays, and hopefully this will allow you to not use the DMIs in cover sprays. You could alternate SDHI (e.g. Miravis) and QoI (e.g. Abound) products as well, and this would give you more cover spray applications (four applications with two…
