Bait treatment should be applied in southern and central Georgia in April and October to eliminate existing fire ant colonies and their mounds, but reinvasion can occur any time, according to University of Georgia entomologist Will Hudson. Four to six months later, the mounds will reappear, which means homeowners should treat for the pests twice a year, about six months apart.

Pecan Trees 03/21/18 Clint Thompson
Dicamba and 2,4-D herbicides, sprayed directly on trees at full rates, kill the plant material they touch, but they don’t travel through the tree or linger from year to year, according to a newly released University of Georgia Cooperative Extension pecan study. The study also found that drift from the herbicides does not hurt the trees.
Cotton roots infected with root-knot nematodes swell in response to the infection. These knots serve as feeding sites where nematodes (microscopic worms) grow, produce more eggs and stunt the plant's growth. CAES News

Mother Nature’s freezing January temperatures reduced nematode buildup in southern Georgia fields. But warmer temperatures this spring could spark nematode activity, according to University of Georgia Cooperative Extension plant pathologist Bob Kemerait.
The fictional Peter Rabbit isn't the only rabbit that enjoys munching in vegetable gardens. To keep rabbits out of home gardens, University of Georgia Extension specialists recommend building a fence around precious plants. The fence must be at least 2 feet high and must be buried 8 to 12 inches deep. CAES News
Rabbit control 03/05/18 Michael Anthony Foster
Rabbits are often welcomed additions to lawns because many homeowners find them adorable. They love to see rabbits at the edges of their lawns early in the morning or in the evening. However, if the population is left unchecked, rabbits can cost homeowners hundreds, even thousands, of dollars a year in damages.
Native azaleas typically have tubular flowers with long stamens that extend beyond their petals. University of Georgia scientist Carol Robacker is studying many of the native azaleas that grow in the Piedmont region to determine which ones are adapted to Georgia. CAES News
Native Azaleas 03/05/18 Sharon Dowdy
Georgians are accustomed to evergreen azaleas, but native azaleas are currently growing in popularity. Unlike evergreen azaleas, native azaleas lose their leaves in the fall, grow tall and airy rather than low and dense, and bloom in the spring and summer.
