Not If Georgia Will Get HLB, But When

Dan CooperGeorgia

Citrus greening disease, also known as huanglongbing (HLB), is not yet widespread in Georgia. However, there’s no reason to think that it won’t become more of a problem for the state’s citrus growers. Lindy Savelle, executive director of the Georgia Citrus Association (GCA), hopes it doesn’t happen but cautions growers about the disease’s potential beyond Florida. “Something we have to …

The first chore for growers in the cold-hardy citrus region when managing citrus greening is scouting for the disease and its vector, the Asian citrus psyllid. The next step is prompt removal of any trees infected with the disease, says Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist. “At this point, we think greening is still …

The dream of citrus varieties being totally resistant to huanglongbing (HLB) disease (citrus greening) is still a distant reality for Florida growers. For now, they must depend on tolerant varieties to lessen the disease’s impact, which is widespread throughout most of the state.

HLB Management Different for North Florida Citrus

Dan CooperCold Hardy, HLB Management

Living with huanglongbing (HLB) disease (citrus greening) is a much different process for citrus growers than protecting their crop from it. Growers in the cold-hardy citrus region are currently trying to keep the devastating disease out of their area.

By Frank Giles While it remains to be seen if trunk injection of oxytetracycline hydrochloride (OTC-HCl) is a game changer in the fight against HLB, it certainly has intensified the conversation about the potential for antimicrobial treatments. There are literally hundreds of materials that might be effective at reducing the HLB bacteria in trees, but it has been a slow …
