By Tripti Vashisth, Taylor Livingston, Meryam Manzoor and Johann Hiller Citrus fruit quality and yield remain major concerns for sweet orange growers in the huanglongbing (HLB) era. These outcomes largely depend on the tree’s ability to support developing fruit throughout the growing season. Leaf area and canopy density are positively correlated with carbohydrate production and allocation to fruit, directly influencing …

Florida’s soils present unique challenges for growers. The soils vary widely from nutrient-poor sandy to highly organic soils, depending on location. These conditions make it difficult to sustainably manage agriculture in a way that supports food production, environmental health and a strong economy. To address these challenges, University of Florida (UF) researchers are leading a four-year study supported by a $749,999 …
By Lauren Fessler Mathews, Ana Redondo and Ozgur Batuman Citrus canker continues to impact Florida citrus, increasing premature fruit drop and decreasing yield and fruit quality. While copper sprays have long been relied upon to control this disease, concerns about environmental impact and possible resistance development have led to efforts to find sustainable alternatives. Previous studies have shown that plant …
After significant drought in many parts of Florida, some much-needed rainfall began in May as the rainy season approaches.

Research and field trials have been fairly consistent in showing that trunk injection of oxytetracycline (OTC) will reduce the HLB-causing bacteria in citrus trees, resulting in improved yield and quality. But what happens to the Asian citrus psyllid (ACP) when it feeds on treated trees? The answer to that question is becoming clearer now from research conducted by the University …
Researcher Ute Albrecht on April 21 shared lessons learned from three years of oxytetracycline (OTC) trunk injection for HLB management in Florida.
