EPA approves genetic technologies to aid citrus growers' recovery

EPA: The U.S. Environmental Protection Agency regulates pesticides, plant-incorporated protectants, and related agricultural technologies to ensure safety and environmental protection. It recently approved CarriCea T1, a gene-edited citrus rootstock that strengthens trees' natural defenses against citrus greening disease through precise edits to the plant's own genes. This decision provides citrus growers with an innovative tool to combat the disease while reducing dependence on conventional chemical sprays. citrus growers: Citrus growers are agricultural producers focused on oranges, grapefruits, and other citrus crops, primarily in states like Florida, California, and Texas. They have endured prolonged challenges from citrus greening disease that has damaged groves for decades. Recent EPA approvals of genetic technologies, including CRISPR-edited rootstocks, offer them new options to restore production and adopt more sustainable disease management practices. Disease Challenge: Citrus greening disease has devastated U.S. citrus production for more than two decades, prompting intensive research into resistant varieties. Industry Rebuilding: Growers are beginning to plant trees incorporating these approved genetic technologies as part of efforts to recover groves and shift toward solutions that leverage the plants' own biology. Regulatory Milestone: The EPA has issued approvals for gene-edited rootstocks and other biotech tools specifically developed to help citrus trees resist greening through edits to their existing genes.
