The …
ACP and the HLB Pathogen Are Made for Each Other
Nabil Killiny, an associate professor of plant pathology for the University of Florida Institute of Food and Agricultural Sciences, has been studying the relationship between the bacterium that causes HLB (Candidatus Liberibacter asiaticus) and its vector the Asian citrus psyllid (ACP). Globally, insect-borne vector pathogens are responsible for more than 700 plant diseases. HLB ranks high among those in terms …
Growers in Northern Regions Whetting Consumer Appetites

Early HLB Detection by Dogs
By Amir Rezazadeh Huanglongbing (HLB), or citrus greening disease, has caused more than 70% decline in the production of oranges for juice and the fresh market in Florida. Once a tree is infected, there is no cure. Early detection followed by a rapid response is important to avoid further spread of the exotic pathogen. Delayed detection of HLB can result in …

Growing Matters, funded by a consortium of agricultural chemical companies, recently launched its fourth annual BeSure! campaign to promote best management practices when using neonicotinoid products on farms and urban landscapes. The campaign uses a wide range of media channels to remind growers, crop protection applicators and others to ensure label directions and responsible stewardship measures are followed for neonicotinoid …
Fruit Size and Spraying Interval Are Key for Canker Control
The size of fruit that should be sprayed, the spraying interval and ways to avoid copper phytotoxicity were among the citrus canker topics plant pathologist Megan Dewdney offered growers recently. Dewdney said fruit are most susceptible to canker when they are between 3/8 inch and 1.5 inches in diameter. The fruit rind becomes much more resistant when the fruit is …
Balancing Citrus Nutrition in the Era of HLB
The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has committed to updating nutrition recommendations for citrus now that HLB is endemic across the state. Some of this ongoing research was discussed during the February All In For Citrus podcast. Growers will be interested to hear from Davie Kadyampakeni, a UF/IFAS assistant professor of soil and water science, …
HLB Update in Georgia
A small amount of citrus greening disease (huanglongbing or HLB) can escalate quickly if growers are not careful. Jonathan Oliver, University of Georgia (UGA) assistant professor and small fruits pathologist, cautioned producers about the disease during the recent Georgia Citrus Association meeting. “The issue is not widespread yet (in Georgia) for sure,” said Oliver. “We don’t think the vector is …

Soil Is Key to Setting Up Trees for Success
By Brad Turner As I started my regenerative journey five years ago, it conjured up memories of walking the family groves in the 1970s with my freshly sharpened eye hoe. I would follow the tractor as it pulled the offset chopper, crisscrossing between the widely spaced trees in all directions. The native grasses and broadleaf plants — including legumes like …
