2023	275,000	24	Two more hurricanes	Polk County leads U.S. in population growth

This timeline illustrates the stark reality facing Florida’s citrus industry. The combination of disease, natural disasters, and urban encroachment has led to a precipitous decline in both acreage and production. Let’s explore each of these factors in more detail.

The Triple Threat: Greening Disease, Hurricanes, and Urban Growth

Citrus Greening Disease: A Microscopic Menace

At the heart of the citrus crisis lies a tiny insect with devastating consequences. The Asian citrus psyllid, carrier of the bacteria responsible for citrus greening disease, has wreaked havoc on Florida’s orange groves since its detection in 2003. This insidious disease, also known as Huanglongbing (HLB), causes trees to produce bitter, misshapen fruit before eventually dying.

The impact of citrus greening on the industry cannot be overstated. It has led to:

Reduced yields and fruit quality
Increased production costs as growers battle the disease
Widespread tree mortality, necessitating frequent replanting
A shift in industry focus towards research and disease management

Dr. Lukasz Stelinski, an entomology professor at the University of Florida’s Citrus Research and Education Center, explains, “Citrus greening has been the most significant challenge our industry has ever faced. It’s not just about treating the symptoms; we’re in a race to find long-term solutions that can save Florida’s citrus heritage.”

Hurricane Havoc: Nature’s Destructive Force

As if disease weren’t enough, Florida’s orange groves have also had to contend with increasingly frequent and severe hurricanes. The impact of these storms on citrus production is multifaceted:

Direct damage to trees, including uprooting and branch loss
Flooding and soil erosion in groves
Disruption of harvesting schedules and infrastructure
Long-term stress on trees, making them more susceptible to disease

Trevor Murphy, a third-generation grower in Lake Wales, Florida, shared his perspective: “When Hurricane Irma hit in 2017, it was a knockout punch for many growers who were already struggling with greening. A tree that loses branches and foliage in a hurricane can take three years to recover. With multiple storms in recent years, some groves never get the chance to bounce back.”

Urban Encroachment: The Pressure of Population Growth

As Florida’s population continues to boom, particularly in citrus-rich areas like Polk County, orange groves are increasingly giving way to housing developments. This urban growth presents both challenges and temptations for citrus growers:

Rising land values make selling to developers an attractive option
Increased competition for water resources
Fragmentation of agricultural areas, impacting grove management
Pressure on local ecosystems and wildlife habitats

“At some point, this isn’t going to be an orange grove anymore,” Murphy observed, pointing to the new homes surrounding his family’s 20-acre grove. “You look around here, and it’s all houses, and that’s going to happen here.”

The Economic Ripple Effect

The decline of Florida’s citrus industry has far-reaching economic consequences that extend beyond the groves themselves. A whole ecosystem of businesses dependent on citrus production is at risk, including:

Juice processors operating at reduced capacity
Packing houses and distributors facing reduced volumes
Fertilizer and agricultural supply companies seeing decreased demand
Citrus-based product manufacturers adapting to limited supply

Tom Davidson, whose family has run Davidson of Dundee Citrus Candy and Jelly Factory since 1966, explains the impact on his business: “The drop in citrus production has affected what flavor jellies we can produce and the prices we charge customers. We’re really hoping that scientists can get this figured out so we can get back to what we did.”

The broader economic impact is significant, with the citrus industry historically contributing $6.8 billion to Florida’s economy and supporting 33,000 full-time and part-time jobs. As production declines, these economic benefits are at risk of evaporating.

The Search for Solutions: Innovation in the Face of Crisis

Despite the dire situation, Florida’s citrus industry is not giving up without a fight. Researchers, growers, and agricultural technology companies are working tirelessly to develop innovative solutions to combat citrus greening and other challenges facing the industry.

Genetic Engineering: The Promise of Bug-Resistant Trees

One of the most promising avenues of research involves genetically modifying citrus trees to resist the Asian citrus psyllid. Dr. Stelinski explains, “We’ve been working for eight years on a genetically modified tree that can kill the tiny insects responsible for citrus greening. The process involves inserting a gene into a citrus tree that produces a protein that can kill baby Asian citrus psyllids by making holes in their guts.”

While this technology holds great promise, it’s still at least three years away from being ready for widespread planting. In the meantime, growers are exploring other innovative approaches to protect their trees.

Protective Cultivation Methods

Some of the strategies being employed to shield citrus trees from the psyllid include:

Planting trees inside protective screens
Covering young trees with white bags to keep out the bugs
Injecting trees with antibiotics to combat the greening bacteria
Identifying and propagating naturally resistant trees

These methods, while labor-intensive and often expensive, are helping some growers maintain production in the face of the greening threat.

Technological Solutions for Precision Agriculture

In the digital age, technology is playing an increasingly important role in agriculture. Companies like Farmonaut are at the forefront of this revolution, offering satellite-based farm management solutions that can help citrus growers optimize their operations.

Farmonaut’s platform provides valuable services such as:

The Future of Florida’s Orange Groves: Adaptation and Resilience

As we look to the future of Florida’s citrus industry, it’s clear that adaptation and resilience will be key to its survival. Growers are faced with difficult decisions: whether to sell their land to developers or persevere in hopes of scientific breakthroughs.

Some, like Trevor Murphy, are taking a hybrid approach. “I would like to think that we’re at the bottom, and we’re starting to climb back up that hill,” he says. Murphy has sold some acreage to developers but is using that capital to reinvest in more productive groves and replant thousands of trees.

Others are diversifying their operations, exploring alternative crops or value-added products to supplement their citrus income. This adaptability may be crucial for the industry’s long-term survival.

The Role of Policy and Support

Government support and policy decisions will play a critical role in shaping the future of Florida’s citrus industry. Key areas of focus include:

Increased funding for research into disease-resistant varieties and treatment methods
Support for growers transitioning to protective cultivation methods
Land use policies that balance urban growth with agricultural preservation
Financial assistance and crop insurance programs tailored to the citrus industry’s unique challenges

Matt Joyner, CEO of trade association Florida Citrus Mutual, emphasizes the importance of these efforts: “Losing the citrus industry is not an option. This industry is so ingrained in Florida. Citrus is synonymous with Florida.”

The Consumer Perspective: Changing Habits and Preferences

As the Florida citrus industry grapples with these challenges, consumer habits are also evolving. Orange juice consumption in the United States has been declining for the past two decades, with a slight uptick during the COVID-19 pandemic. This trend adds another layer of complexity to the industry’s struggles.

Factors influencing consumer behavior include:

Increased awareness of sugar content in fruit juices
A shift towards whole fruits and alternative beverages
Growing interest in locally sourced and organic produce
Concerns about the environmental impact of large-scale agriculture

To address these changing preferences, the citrus industry may need to innovate not just in production methods, but also in product development and marketing strategies.
