University of Florida Institute of Food and Agricultural Sciences researcher Xavier Martini recommends planting windbreaks on two or more sides of citrus groves. He gave this advice to growers at a recent Citrus Insect Management Workshop in Lake Alfred, Florida. Martini said windbreaks do a good job of keeping canker and HLB-spreading psyllids out of groves. The trees also help …

A shift toward reduced use of insecticides in Florida groves could lead to the emergence of pests that haven’t generally been a problem for years, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lauren Diepenbrock said. Pests that could return or emerge in the face of reduced insecticide use include scales, mealybugs, false spider mites and fruit …
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) entomologist Lukasz Stelinski suggested ways growers can cut psyllid control costs.

An analysis by California Citrus Mutual (CCM) indicates there is no major impact at the present time on government programs that affect California’s citrus industry. This could change if the shutdown drags on, however. According to the report, “Our major priority would be the ACP/HLB program sometimes known as CHRP (Citrus Health Response Program). We are not suffering any major …
Nutrient deficiencies are common in HLB-affected trees, which make up the vast majority of Florida citrus trees. At a recent Citrus Nutrition Day in Bartow, University of Florida Institute of Food and Agricultural Sciences researcher Arnold Schumann discussed ways to identify and avoid nutrient deficiencies. A common identification method for nutrient deficiencies is direct observation, “walking through your grove, …
When the next frost threatens Florida’s crops, growers will do their best to make sure your favorite foods are protected from the potentially crippling chill, say University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) experts. For example, citrus growers use wind machines and microsprinklers to ensure freezing temperatures don’t ruin the fruit, said Chris Oswalt, a multi-county citrus …

Citrus leafminer (CLM) and root weevils are two pests that have been raising concerns and adding to the challenge of managing productive citrus …
A primary job for scientists breeding citrus in Uruguay is to help the approximately 42,000-acre industry develop fresh fruit for export, Fernando Rivas said at a recent international citrus breeders symposium in Lake Alfred, Florida. Rivas works for Uruguay’s National Institute of Agricultural Research. On. Dec. 4, Rivas told an audience of about 70 at the Citrus Research and Education …
