CRAFT is a first-of-its-kind program and considered an innovation among funding agencies needed to support such efforts. …
Protect Developing Fruit From Lebbeck Mealybugs
By Lauren Diepenbrock As the March bloom tapers off and fruit begin to set, it is time to think about lebbeck mealybug management to protect developing fruit. Damage to setting fruit causes malformed fruit that are often aborted or not marketable if they continue development (Figure 1). Early-season management is critical to both reducing early fruit damage and to maintaining …

‘The Psyllids Will Like Georgia Just Fine’
A California citrus leader believes Georgia will make an ideal home for the Asian citrus psyllid, which vectors the devastating huanglongbing (HLB) disease. “North of Florida, it is colder, and it’s certainly not as suitable a place as Florida is, but the psyllid is still going to be fine. The cold isn’t long enough here to knock the populations out,” …
Turkish Lemon and Grapefruit Production to Rise

Half of the total lemon production in Türkiye …
Growers Must Settle for HLB-Tolerant Trees While Waiting for Resistance
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. Michael Rogers, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Citrus Research and Education Center …

Continued Commitment to Florida Ag
By J. Scott Angle, jangle@ufl.edu When I arrived in Florida three and a half years ago to lead the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), my message to Farm Bureau members was, “I work for you.” I still do, but no longer as UF’s senior vice president for agriculture and natural resources. I’ve become provost, the …
Mexican Organic Orchards Offer Better Psyllid Control
A wider diversity of weeds and insects in organic Mexican citrus orchards compared to conventional orchards aids in control of the HLB-spreading Asian citrus psyllid (ACP/Diaphorina citri), a Mexican scientist reported recently. HLB is also known as citrus greening disease. “In the organic orchard, there are almost double the species of weeds compared to the conventional orchard,” Carlos Castillejos Cruz …
