Should the agriculture industry prioritize adopting new biological treatments to combat crop diseases?
The Environmental Protection Agency has officially registered a new treatment for citrus greening disease that utilizes protective compounds found in spinach. This development arrives after 15 years of collaborative research into saving citrus crops.
Why it matters
Citrus greening is a devastating bacterial infection that has severely hampered citrus production. The new treatment helps trees fight this infection by using a modified citrus virus to induce the production of spinach-derived compounds.
The treatment was developed over a 15-year period of research conducted by the University of Florida, Texas A&M AgriLife Research, and private industry. The process uses a modified citrus virus without altering the tree's genetic makeup.
The players
Environmental Protection Agency
This federal agency is responsible for the protection of human health and the environment through the regulation of agricultural treatments.
Silvec Biologics
This private industry partner is slated to lead the deployment of the new citrus treatment through upcoming field trials.
University of Florida
This institution is a leading center for agricultural science that collaborated on the long-term research for the new treatment.
Texas A&M AgriLife Research
This state agency conducts research on agricultural and environmental issues and served as a core developer of the spinach-based solution.
The details
The treatment is administered by introducing a modified citrus virus into trees through grafting. This method prompts the trees to produce protective compounds that specifically combat the bacteria causing the disease.
Timeline
Research for the treatment spanned from 2011 to 2026.
Silvec Biologics expects to begin working with Florida growers in late 2026.
The Big Picture
This development marks a shift in how researchers address agricultural pathogens by utilizing natural biological compounds. The integration of this treatment into the Citrus Research and Field Trial program signals a major step toward scaling new disease-fighting solutions.
This treatment helps stabilize citrus crops, which may lead to more consistent fruit availability and pricing for consumers. It offers a new path for growers to manage disease without resorting to genetic modification of the trees.
The takeaway
This breakthrough provides a non-genetic way for trees to defend themselves against a common threat. Implementing these types of natural compound treatments could provide a sustainable future for the citrus industry.
What happens next
Silvec Biologics is scheduled to begin working with Florida growers through the Citrus Research and Field Trial program in late 2026.
