Citrus researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are taking a more comprehensive look at how tools to manage HLB affect young trees. The goal is to develop integrated approaches and update management practices for growers. After one year of the research project, some interesting results are already emerging. The research project, “Establishing Healthy …
University of Florida multi-county citrus Extension agent Chris Oswalt discussed fungal disease management in the April Central Florida citrus Extension newsletter. Here is a summary: In Florida, fruit fungal diseases that are oftentimes problematic in the early spring are melanose, scab and alternaria brown spot, along with citrus canker. In the summer period, greasy spot is more of a problem, …
Preventing HLB infection in newly planted citrus trees with individual protective covers (IPCs) can improve productivity and fruit quality. Thus far, IPCs have kept young citrus trees free of HLB in research plots. “Once you plant a tree, if it’s not protected, it’s exposed to HLB infection from day one,” says Fernando Alferez, an assistant professor at the University of …
By Megan Dewdney Greasy spot and melanose are two fungal diseases that have long needed the attention of Florida citrus growers. While they are more of a concern for fresh fruit growers, trees for processing can be damaged, too. In terms of management priorities, greasy spot is the greater concern since it reduces tree photosynthetic capacity and causes defoliation. Melanose …
Sometimes growers must think outside the box to remain sustainable amid high input costs and devastating diseases. That is the situation facing citrus growers who are struggling to remain viable in the era of citrus greening. What if seaweed could be used to aid in the quality of citrus production? Seaweed is a biostimulant that is part of the biological …
A coalition of groups on March 25 sued the Environmental Protection Agency (EPA) for approving spraying of streptomycin on citrus trees to prevent or treat HLB or citrus canker. The groups claimed that the practice of spraying antibiotics on trees has been ineffective in combating the diseases and can drive antibiotic resistance in bacteria, which can threaten human health. The …

Little to no postbloom fruit drop (PFD) was reported during the 2020 bloom because of a sudden dry spell as the flowers opened. As spring 2021 approaches, the forecast is for a La Niña weather pattern with slightly warmer …
By Ajia Paolillo Editor’s note: This article grants one continuing education unit (CEU) in the Core category toward the renewal of a Florida Department of Agriculture and Consumer Services restricted-use pesticide license when the accompanying test is submitted and approved. Integrated pest management (IPM) uses a combination of methods to keep pest populations at an acceptable level, which are economical …
Visual identification of nutrient deficiencies and leaf damage is an important diagnostic tool for fine-tuning management of citrus. Arnold Schumann, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor, shared how UF/IFAS researchers have used artificial intelligence (AI) to diagnose citrus nutritional deficiencies, diseases and pest damage. According to Schumann, disease and pest symptoms on leaves may cause …
While everyone strives to protect themselves from coronavirus disease, growers have an additional concern: protecting their trees from citrus disease. While HLB is of course the most damaging disease of citrus, there are other diseases that should not be overlooked. Disease management is the theme of the February 2021 issue of Citrus Industry magazine. University of Florida Institute of Food …
By Xavier Martini and Danielle Sprague Cold-hardy citrus, that is, citrus grown above the 30th parallel north, is a blooming industry. In less than 10 years, the acreage in North Florida has gone from almost nonexistent to approximately 1,000 acres. Growers in the region plan to plant more in the coming years. In Georgia, there are approximately 2,000 acres across …
One of the main issues for citrus crop growers is the quick spread of fungal and bacterial diseases due to warm, wet growing conditions.
