Keep Current With MRLs for Exports
By Mark A. Ritenour The United States and other countries set maximum residue limits (MRLs) on fresh produce for various chemicals, including pesticides that might be used before or after harvest. These materials must be labeled for use on the crop of interest and used only according to label instructions. While it is unlikely for U.S. MRLs to be exceeded …
Making Sense of Biologicals: Biofertilizers Designed to Make Roots ‘Happy’
“If mama ain’t happy, ain’t nobody happy.” That same mindset can also be applied to agriculture. If the roots of a plant are not happy, the top of the plant won’t be happy either. Anything else will prove to be futile, believes Mark Egan. Egan, an agronomist at Douglas Plant Health, says biofertilizers are a management tactic that growers can …
Keeping HLB out of California Groves

On the room for improvement side, the board suggested “that we needed to have a …
Sneak Peek: June 2021 Citrus Industry
There is no arguing that citrus greening has been the biggest change to the industry in the past 16 years. The disease is causing growers to do things differently. Researchers are helping growers adapt to change and find new solutions. Some of this research can be found in the June issue of Citrus Industry. FRUIT DROPOne of the problems exacerbated …
Monitoring Citrus Root Weevils
By Larry Duncan Soilborne larvae that feed on citrus roots are the damaging life stage of Diaprepes abbreviatus and Pachnaeus spp. (bluegreen) root weevils. Newly developed adult weevils, which emerge throughout the warm months of the year, also occur in soil. A peak emergence of adults occurs at some point each spring or early summer. Less frequently, a smaller emergence …
Florida Grower Advises California on HLB
Pete Spyke, a Florida gift fruit citrus grower and shipper, recently offered some advice to California citrus growers for dealing with HLB. In a letter to California’s Citrus Pest & Disease Prevention Program, Spyke suggested that growers continue to detect and remove HLB-infected trees. Spyke’s letter follows: Dear California Citrus Growers, Based on my observations and discussions with growers and …
Advances in Therapeutics for HLB Control
The U.S. Department of Agriculture (USDA) is examining different ways to deliver therapeutics to citrus trees for management of citrus greening disease, also know an huanglongbing (HLB). The hope of the USDA initiative is to establish an HLB-therapeutic molecule and identify the most cost-effective strategy to deliver these molecules to growers. The project is in collaboration with the University of …
Optimizing Irrigation and Young Tree Management
By Davie Kadyampakeni and Sandra Guzmán Young citrus trees require optimal irrigation management for vigorous vegetative growth, leaf flushing and the establishment of a dense canopy. Poor practices such as infrequent irrigation or not using irrigation scheduling tools could be costly. Young tree growth also could be impacted by excessive water and nutrient losses. Crop water stress in young trees …
Agriculture Group Addresses Climate Change
Florida agricultural leaders launched an initiative to identify and implement climate-smart agriculture solutions and ecosystem services that benefit the public, producers and the planet.

Grower: Production Dips, but Still Profitable
Hardee County, Florida, orange grower Kenny Sanders saw his orange production dip in the 2020-21 season compared to the prior year. However, he still made a good profit, thanks to strong fruit prices. “I went down from 400 boxes an acre to 308 boxes, which I can live with, but it’s not as nice,” Sanders said. “We had a good …
Preserving Beneficial Insects
Beneficial insects could be a citrus grower’s best friend. In a time when producers are applying insecticides to control the Asian citrus psyllid, the vector of citrus greening disease, it’s important to preserve the psyllids’ natural enemies, like lady beetles and lacewings. Jawwad Qureshi, University of Florida entomologist, implores growers to scout their groves periodically to see what insects are …
Keep Citrus Trees Hydrated
Frequent irrigation with good quality water can improve fruit growth and development and overall productivity. By Tripti Vashisth HLB-affected citrus trees have small and weak root systems. Though the roots are efficient in taking up water and nutrients, there are not sufficient roots to support the tree’s canopy requirement. Therefore, the trees often experience water and nutrient deficit. Not all …
