The United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has analyzed the potential environmental effects of establishing an integrated management strategy to control cogongrass in Alabama, Georgia, Mississippi, and South Carolina. The draft environmental assessment is now available for comment. Cogongrass is an invasive exotic grass found on public and private property, along roadways, in forests, and on farmland. This federally regulated noxious weed grows rapidly, reducing forest productivity, harming wildlife habitat and ecosystems, and encroaching on pastures and hayfields. Because of cogongrass' impact on agriculture and forest industries, Congress has given APHIS funding to partner with Alabama, Georgia, Mississippi, and South Carolina to control the spread of this weed. APHIS is proposing is an integrated management strategy that uses preventive, cultural, mechanical, biological, and chemical methods to control cogongrass in key areas of its distribution. APHIS invites the public to review and comment on this environmental assessment by April 1, 2020.

Boxwood blight (also called "box blight" in Europe), caused by the fungal pathogen Cylindrocladium pseudonaviculatum (=C. buxicola), was found for the first time in the United States in North Carolina, Virginia and Connecticut in 2011. The first reported infestation in the U.S. was in a North Carolina nursery and the disease was introduced to Virginia on plants from that nursery. Spread outside the two Virginia locations, both of which are fields owned by a single nursery, has not been reported. However, growers should be aware of the symptoms of boxwood blight and monitor nursery and landscape boxwoods for symptoms.

A plant disease that presents a serious threat to the U.S. citrus industry has been detected in Alabama. Federal and state plant health officials have confirmed the identification of citrus greening (CG), also known as Huanglongbing or HLB, which is caused by the bacterial pathogen Candidatus Liberibacter asiaticus. This is the first confirmation of citrus greening in Alabama despite biannual surveys for the pathogen by the Alabama Department of Agriculture and Industries (ADAI).

One of the most invasive weeds in the world is beginning to make its way into north Mississippi, announced the Mississippi Forestry Commission (MFC). "Cogongrass was introduced to Mississippi as a new forage crop, however, it is not palatable for livestock, not even goats will eat it," Bozeman said. "It also failed as an erosion control plant because it was too weedy. With no native competition or consumers, cogongrass spread rapidly throughout the Gulf South." There is widespread cogongrass infestation in south Mississippi, but the MFC is starting to see and get reports of the weed moving into the northern part of the state. If left unchecked, cogongrass could become a statewide problem.

Bozeman wants landowners in north Mississippi to be on the lookout for cogongrass on their property and the notify the MFC if they suspect the invasive weed has taken root. "The Mississippi Forestry Commission can offer assistance to landowners in north Mississippi who have cogongrass on their property," said Bozeman. "We can also come out and help landowners determine if what they are seeing is cogongrass or not." For more information and to fill out the program application, visit the Cogongrass Control Program. If you suspect you have cogongrass on your property, call your local MFC forester to come do a site visit.
