Tiny Pest, Big Pasture Problems Across the Southeast
A tiny insect is creating some big concerns for cattle producers across the Southeast.
Pasture mealybugs were first detected in Florida in May. Since then, infestations have been confirmed in more than two dozen Florida counties, and Georgia recorded its first detection in August.
Alabama wasn't among the states with confirmed detections listed by USDA as of last month, but Extension specialists there are encouraging producers to watch for the pest.
These insects feed on warm-season grasses, including bermudagrass and bahiagrass, causing yellowing, reddish or purple discoloration, and potentially significant pasture dieback.
Now, researchers at the University of Florida are reporting progress on management options.
Preliminary findings suggest cutting or grazing infested forage can help reduce insect populations, although neither eliminates the pest. Certain systemic insecticides are also showing promise, but results vary.
Meanwhile, Extension specialists are emphasizing early detection and cleaning equipment between fields to help prevent further spread.
For producers across all three states, the recommendation is to monitor pastures for unusual damage and contact local Extension offices if an infestation is suspected.
