Fungal foliar diseases significantly threaten commercial citrus production by reducing fruit packout and overall crop yield. Tangerines and mandarins are highly susceptible to these pathogens, particularly Alternaria brown spot and citrus scab. In a presentation at the recent Citrus & Specialty Crop Expo, Megan Dewdney, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) plant pathologist, outlined proactive management …
By Lauren Fessler Mathews, Ana Redondo and Ozgur Batuman The positive impact of oxytetracycline (OTC) trunk injections for citrus production in HLB-infected trees has been well established. Additionally, there has been extensive work showing that plant defense inducers (PDIs) can help boost tree health and reduce symptom development from a variety of pathogens. Based on this, University of Florida Institute …
There’s been a great deal of effort over the past 15 years or so to develop or identify citrus varieties and rootstocks that have greater tolerance to HLB. That work has resulted in a lot of options to sort through when making selections for planting resets or new blocks. There have been more than 50 cultivars released in recent years. …
By Lauren Diepenbrock Red imported fire ants (Solenopsis Invicta), commonly referred to as fire ants, are commonplace throughout Florida. The pest infests a broad range of habitats, including urban sites, natural areas and production fields. In citrus, a range of impacts from this pest are seen. From a human health perspective, fire ant stings can cause symptoms from mild irritation …
