The onset of spring means preparing for insect pests if you are a fruit tree producer. Plum curculio is the most destructive insect that attacks early-season fruit. “If you have fruiting trees, especially peaches, now is the time to ramp up your monitoring efforts for plum curculio to determine if and when management decisions will need to be made,” urged …
Freeze Impact on Florida Peaches
By Clint Thompson Count Florida’s peaches among those crops impacted by the sub-freezing temperatures almost two weeks ago. The difference in the producers who protected their crop and those who did not was unmistakable, says Jose Chaparro, associate professor in the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). “I can tell you that anybody north of central …
Chill Hour Accumulation: Alabama Peaches Still Behind
By Clint Thompson Cooler temperatures in January have provided hope for peach producers yearning for chill hour accumulation. Though Alabama’s crop is still behind the total from last year, it still is progressing, says Edgar Vinson, assistant research professor and Extension specialist in the Department of Horticulture at Auburn University. “We’ve progressed some in the amount of chill. We are …
Avoid Fungicide Resistance Development in Peaches
By Clint Thompson Avoiding fungicide resistance in peach production is front and center of Phil Brannen’s presentation this week at the Southeast Regional Fruit and Vegetable Conference in Savannah, Georgia. The University of Georgia Cooperative Extension Fruit Disease Specialist cautions producers about overusing products like Miravis to protect against peach scab disease. “The thing about Miravis that’s tempting is it’s …
Chemistry Rotation Needed to Protect Peaches Against Plum Curculio
By Clint Thompson Southeast peach producers have a handle on plum curculio management. Brett Blaauw, assistant professor at the University of Georgia (UGA) College of Agricultural and Environmental Sciences, wants to keep it that way. That’s why the UGA specialist continues to encourage rotation of chemistries to prevent insecticide resistance from occurring. Pyrethroids are growers’ best option for management. But …
Improving Productivity of Florida-Grown Peaches
By Tripti Vashisth Unlike citrus, peaches are deciduous fruit trees. Deciduous trees shed their leaves during the late fall and early winter and undergo dormancy. During this dormant stage, a certain amount of cold weather (measured by an accumulation of chill units) is needed to resume normal growth in the spring. When the cold weather requirement for dormancy is fulfilled, …
UF Research: Bags on Peaches Help Keep Pests, Diseases Away
Peaches are popular, especially in the Southeast, with annual national production of about 806,000 tons. Growers can help keep pests and diseases from damaging the fruit by placing bags around individual peaches, University of Florida researchers say. David Campbell, a UF/IFAS post-doctoral researcher, led new research, funded by a U.S. Department of Agriculture Organic Research and Extension Initiative grant. UF/IFAS …
Good Start for Georgia Peaches
By Clint Thompson So far, so good for Georgia’s peach producers. Jeff Cook, University of Georgia Cooperative Extension Agriculture and Natural Resources agent for Peach and Taylor counties, said farmers have been harvesting peaches in middle Georgia for more than three weeks. Though the harvest season is still early, there have been no complaints. “Price is good. Quality looks pretty …
Twig Dieback: What to Look for and How to Protect Peaches
While peaches can be a sweet summertime treat, if trees are impacted by twig dieback, that can leave a sour taste in producers’ mouths. Plant diseases cause the twigs, branches and shoots of a peach tree to die. Alabama Cooperative Extension System Plant Pathologist Ed Sikora offers tips about what causes twig dieback, its symptoms and how to manage the …
Alabama Peaches Progressing Following Recent Freeze
Alabama peaches are progressing but there was some damage from a freeze in February, said Doug Chapman, Alabama Extension agent for Commercial Horticulture in North Alabama. “We’re in full bloom right now, maybe in central and south Alabama, a little post bloom. I doubt there’s any shucks split just yet in central Alabama,” Chapman said. “The freeze hurt us to …
