Florida Citrus Fights Back Against Tree Killers

Florida's citrus industry, a century-long economic pillar, faces an existential crisis. Production has plummeted by approximately 92% since 2004, reaching a historic low in the 2024-2025 season. This severe decline is primarily attributed to the invasive Asian citrus psyllid and the bacterial disease it carries, citrus greening (Huanglongbing).

Despite these challenges, a dedicated effort is underway to revive the industry. Researchers and growers are developing trees with enhanced resistance to citrus greening through advanced breeding and genetics. Furthermore, the expansion of growing acreage under protective screen structures offers a shield against psyllids, promoting faster growth and higher fruit quality.

These innovative strategies, supported by state and federal programs, aim to combat the disease and revitalize Florida's citrus groves. While the threat of citrus greening remains significant, the collaborative work between farmers and scientists offers a promising path forward for this iconic agricultural sector.
