Three products approved
The U.S. Environmental Protection Agency (EPA) has approved new five-year registrations for two dicamba products and extended the registration of an additional dicamba product for use on dicamba-tolerant cotton and soybeans in a decision estimated to save growers and producers of the products millions of dollars in lost revenue.
A supergene is a collection of neighboring genes located on a chromosome that are inherited together due to close genetic linkage. Studying these unique genes is important to understanding the potential causes for differences among the social structure of fire ants, specifically for controlling the species and building upon the existing knowledge base.

Fire ant supergene
A unique study conducted by University of Georgia entomologists led to the discovery of a distinctive supergene in fire ant colonies that determines whether young queen ants will leave their birth colony to start their own new colony or if they will join one with multiple queens. Researchers also found that ants were more aggressive toward queens who don’t possess the supergene, causing colony workers to kill them. This critical finding opens the door to new pest control methods that may be more efficient in eradicating problematic fire ant colonies.

Milkweed Pests
With the fall migration underway for monarch butterflies through November, gardeners should soon start seeing the colorful creatures on their travels south. It's also time to be on the lookout for pests of common milkweed (Ascelpias tuberosa), the most popular milkweed plant grown in Georgia butterfly gardens.

Cool Weather Pests
As the weather cools across the state, several fall insects will begin to take center stage around Georgia homes. Be on the lookout for these nuisance pests and make preparations to deter them from entering your home for the winter.

Fighting Pecan Scab
University of Georgia researchers will begin a series of trials this winter to help identify better management practices for pecan growers in Georgia.

Following the onset of several major outbreaks of foodborne pathogens traced back to wildlife, buyers of farm-fresh produce began encouraging the removal of natural habitats and nesting areas on farms to discourage wildlife intrusion.

TSWV Control
Come August, the state's peanut growers will either see the payoff of their spring efforts to control for tomato spotted wilt virus, or they will be planning ways to preventatively manage this persistent virus with recommendations from University of Georgia scientists.
Test plots at the the J. Phil Campbell Research Farm located near Watkinsville, Georgia, show (from left) cereal rye, no cover crop, living white clover mulch and crimson clover approximately three weeks after cotton planting. Areas in red indicate where Palmer amaranth seed was planted and will be monitored for suppression and reproduction over the next several years. CAES News

Getting it covered
University of Georgia researchers are working on natural solutions to weed problems in row crops as government regulations of chemical herbicides grow stricter.
Abnormally dry conditions this summer have kept Georgia's mosquito populations mercifully low, but that's no reason for Georgians to let down their guard, especially this season. CAES News

Mosquito Control
It officially turned summer this past weekend and the weather forecast seems to agree, with thunderstorms and warm nights in our future. These conditions are pretty typical for summer in Georgia — and excellent for mosquito development.
