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 …
Promoting Orange Juice for Hydration
It may not officially be summer yet, but with temperatures heating up, Steve Johnson, chairman of the Florida Citrus Commission, has a reminder about the value of drinking orange juice (OJ) for hydration. “A glass of orange juice is a great hydration option in addition to water since it naturally contains a high percentage of water — almost 90%, says …
Principles and Risks of Trunk Injection for Delivery of Crop Protection Materials
By Ute Albrecht and Leigh Archer Trunk injection is a targeted delivery of materials into the stem or trunk of trees as an alternative to spraying or soil drenching.

New citrus technology and tried-and-true techniques are among the article topics in the May issue of Citrus Industry magazine. Yiannis Ampatzidis, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) assistant professor, discusses several ways artificial intelligence is being used to improve citrus production and reduce negative environmental impacts. Among the topics he covers in his article are automated …
Herbicide Adjuvants in Citrus Weed Control
By Ramdas Kanissery Adjuvants (derived from Latin, adiuvare: to aid or help) are materials added into an herbicide spray solution that improve handling, performance and crop safety. To be effective, an herbicide must overcome certain environmental and biological obstacles before entering and acting in the weeds. For example, environmental conditions like hot and dry weather will result in a thicker …
Mexico Considers Quality Seal for Lemons
By Francisco Seva Rivadulla Due to the importance of differentiation in international markets, the Mexican lemon sector is studying the possibility of creating a national quality seal for its lemons. “The future of our lemons must involve the creation of a national quality seal, which will differentiate them from countries such as Egypt, Turkey or South Africa, and thus generate …
Vaccinating Trees Against CTV and HLB
University of Maryland virologist Anne Simon and the company she founded, Silvec Biologics, have successfully vaccinated laboratory hosts against citrus tristeza virus (CTV). They are now focusing on HLB, also called citrus greening. The vaccination induces trees to produce their own therapeutic agents. Silvec’s vaccination concept is based on the discovery of a novel infectious RNA that the company calls …
PIECES OF THE PAST: A Quatrain to Frame
By Brenda Eubanks Burnette In the July 15, 1933 issue of the Florida Clearing House News, an article by the Committee of Fifty titled “To Fit Demand to Production – ADVERTISE” caught my eye. Advertising has always been the tennis ball in the citrus industry’s battle over how much is enough and whether generic advertising really helps. The Committee of …
Above-Average Hurricane Season Predicted
Colorado State University (CSU) researchers are predicting an above-average Atlantic hurricane season in 2021, citing the likely absence of El Niño as a primary factor. Tropical Atlantic sea surface temperatures are near their long-term averages, while subtropical Atlantic sea surface temperatures are much warmer than their long-term average values. The warmer subtropical Atlantic also favors an active 2021 Atlantic hurricane …
Plan Greasy Spot and Melanose Management
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.

Spain’s Lemon Sector Aims to Further Reduce Carbon Footprint
Although Spain’s lemon industry is a net fixer of atmospheric carbon dioxide (CO2) and its carbon footprint is favorable, the industry could promote even greater CO2 fixation in the future. That’s one of the conclusions from a recent report from the Lemon and Grapefruit Interprofessional Association (AILIMPO). AILIMPO has indicated a series of recommendations; if implemented in the coming years, …
