Florida’s strawberry industry continues to face increasing pressure from chilli thrips, one of the most difficult pests to manage during the production season. At the 44th Annual Florida Strawberry Growers Association AgriTech meeting on May 5, 2026, held at the Grimes Family Agricultural Center in Plant City, Florida, the Florida Ag Research team presented new field research focused on season-long insecticide resistance management strategies for chilli thrips in strawberry production.

The presentation, titled “Optimal Insecticide Resistance Management Rotations for Chilli Thrips: Characterizing Impacts on Populations and Fruit Quality,” was authored by Dr. Frank V. Sances, Dr. Balaji Aglave, and Erin Downey of Florida Ag Research.

The research addressed one of the industry’s most important questions: how to maintain effective chilli thrips control throughout the season while protecting fruit quality and preserving long-term insecticide performance.

Early Intervention and Resistance Management
The presentation emphasized that chilli thrips populations often establish early in the season, well before canopy closure, making early intervention critical for effective suppression.

Researchers noted that programs initiated during the first month of crop establishment improved coverage and delayed population buildup later in the season.

​Researchers noted that sprays applied during the first month of establishment can improve canopy penetration, delay population buildup, and reduce downstream damage to foliage, blossoms, and fruit. 

To evaluate season-long management strategies under commercial-style conditions, Florida Ag Research conducted field trials at the Dover FSGA Research Site using the strawberry variety ‘Ember.’

​Weekly applications were evaluated from December through late April, with researchers monitoring both thrips populations and fruit quality outcomes throughout the season. 

The study compared multiple resistance management approaches, including:

• Rotational programs utilizing multiple modes of action (MOA)
• Programs combining soil and foliar applications
• Foliar-only rotational programs
• Organic treatment programs
• Untreated control plots

Researchers measured thrips populations in both foliage and flowers, while also tracking feeding damage, infestation incidence, and overall marketable yield.

Key Findings from the Trial
The presentation demonstrated clear differences between resistance management programs.

Among the most significant findings:

• Multiple MOA rotational programs provided the strongest foliar suppression, maintaining populations below four thrips per leaf throughout much of the season under sustained pressure conditions.

• Scenario I programs combining Admire Pro with foliar rotations consistently reduced feeding damage and maintained lower flower infestation pressure. 

• Organic programs experienced substantial late-season control failures under high-pressure conditions, exceeding 80% fruit infestation during peak pressure periods and performing statistically similar to untreated controls in feeding incidence evaluations.
• The highest estimated marketable yields were produced by the Multiple MOA program (12,224 lbs/acre) and Scenario I (11,957 lbs/acre), compared to 8,574 lbs/acre in the organic rotation program.

Researchers also highlighted an important scouting takeaway: sampling only trifoliates may underestimate actual field populations, and whole-plant sampling may provide a more accurate picture of chilli thrips pressure during the season.

Supporting Better Decision-Making for Strawberry Production
The presentation reflects Florida Ag Research’s continued focus on generating practical, field-driven data that helps growers and product developers make better management decisions under real-world production conditions. ​
​
As resistance management becomes increasingly important across specialty crop production, this type of season-long efficacy work provides valuable insight into how rotational programs impact not only pest populations, but also fruit quality and marketable yield outcomes.

The complete presentation includes detailed seasonal rotation programs, product-by-product treatment sequences, MOA comparisons, population trend charts, environmental observations, feeding damage analyses, and full marketable yield data from the trial. For growers, consultants, and product developers seeking deeper technical insights into chilli thrips resistance management strategies, the full presentation provides substantially more detailed trial data and program structure.​

​At the Florida Strawberry Growers Association’s Annual Tailgate in Dover, FL on January 14th, Florida Ag Research shared current findings from field work evaluating insecticide spray programs for chilli thrips management in Florida strawberry, with a focus on thrips populations, fruit quality, and practical sampling considerations. 

Why early-season thrips management is a focal point
Chilli thrips populations can build quickly in the first third of the season. Early sprays do not always prevent damage to foliage, blossoms, and fruit, which is why the current strategy emphasizes early intervention—applications during the first month of establishment (before canopy closure) to improve coverage and delay population buildup.

Field trials are currently underway at the Dover FSGA Research Site to refine early-season application methods under real-world conditions, including examining products and modes of action targeting oviposition, eggs, and immatures.

Trial overview and what was evaluated
In this study, ‘Ember’ strawberry was planted 10/20/2025, and five treatments were compared: four rotation programs plus an untreated check (UTC).

Applications and Assessments

• Application timings: 12/22, 12/31, 1/7

Assessment methods included:

1. Thrips counts on leaves (emerging trifoliate)
2. Thrips counts on blossoms (five blooms per plant; alcohol bath; microscope counts)
3. Fruit evaluations (% thrips damage on harvested fruit)

The rotation programs represented different scenarios (including conventional rotations, a multiple-MOA approach, and an organic program), framed around IRAC mode-of-action considerations.

Key findings (early-season conditions)
1. Population control vs. crop protection can diverge
Across assessments focused on adults + larvae per flower, the data indicated that IGR-based approaches provided stronger thrips population reduction relative to systemic and contact products in this dataset.

2. Fruit protection and marketable outcomes favored systemic programs in this early window
When looking at harvested fruit outcomes after three harvests, the presentation notes that a program with systemic products provided the best fruit protection under the early-season conditions observed.
Marketable yield results were also summarized with an emphasis on early-season ROI dynamics, noting that systemic products can provide strong ROI compared to other rotations, though the untreated check performed similarly under these specific early-season conditions.

3. Sampling location matters (flowers vs. foliage)
The work also addressed the practical question: Where should you sample, flowers or foliage? The dataset presented a comparison of adults + larvae per leaf and summarized percent control by program.

Separately, the presentation’s conclusions noted more thrips found in blossoms vs. foliage in these plots.

Conclusions and Next Steps
​The presentation closed with several clear takeaways:

• Relatively low thrips populations in our plots despite our best efforts
• More thrips found in blossoms vs. foliage
• IGR’s provide better population control, but systemic products protect marketable yield better in early season conditions
• Continue to characterize population dynamics of thrips in real-world conditions and understand how IGR’s fit into management programs

​Leaders across the banana industry are voicing a common concern: the production model that has supplied affordable fruit to consumers for decades is under real pressure.
 
On recent earnings calls and in global media, executives have pointed to a convergence of threats – aggressive diseases, changing climate patterns, and persistent economic pressures – that make it harder to maintain yield, quality, and profitability in traditional production regions. (Shah, 2025) (Abu-Ghazaleh, 2025)
 
For those of us working in crop protection and biology R&D, this moment is not just a headline. It is a signal that the industry needs scalable, field-proven solutions that can help production systems absorb stress and remain viable.
 
Why bananas are uniquely vulnerable
Bananas are a global staple and one of the world’s most traded fruits. The export supply chain depends heavily on large-scale monocultures of a narrow set of cultivars, often under warm, humid conditions that are ideal for fungal diseases. (Shah, 2025)

​The result is a system where disease outbreaks, extreme weather, or logistical disruptions can have outsized impacts on both producers and downstream customers.
 
What R&D teams need from field research
In this context, product development teams – whether working on fungicides, biologicals, soil amendments, or integrated crop management programs – need more than small-plot efficacy data in ideal conditions.
 
They need field research that can:

1. Replicate real-world stress. Trials must be conducted under genuine disease and pest pressure, with the heat, humidity, and soil constraints that mirror production realities.
2. Connect field performance to fruit quality and shelf life. For bananas and other tropical fruits, a promising program on the plant must also protect firmness, appearance, and post-harvest performance.
3. Capture system interactions. Diseases like TR4 and Black Sigatoka do not act in isolation. Nematodes, soil health, root function, and nutrition all influence expression and severity, as well as the plant’s ability to recover.
4. Provide clear, decision-ready outputs. Development teams need statistically sound, well-documented studies that can guide go/no-go decisions, label refinement, and positioning – and that are repeatable across seasons and sites.

 
How Florida Ag Research supports banana and tropical crop resilience
Florida Ag Research, part of Ag Metrics Group, operates in a subtropical environment where high humidity, intense rainfall events, and extended growing seasons create the kind of stress that tropical crops experience in many commercial regions.

A role for independent research in a changing risk landscape
The challenges facing the banana sector are not going to disappear quickly. Climate trends suggest that disease pressure and weather variability will likely increase in key production regions. (Shah, 2025)
In that environment, independent field research organizations have an important role to play:

• Stress-testing new tools before they reach commercial scale
• Helping refine integrated programs that blend fungicides, biologicals, soil and root health approaches, and careful nutrition
• Providing unbiased, decision-focused data that growers, buyers, and brand owners can rely on as they adjust their strategies

 
At Florida Ag Research and across Ag Metrics Group, our focus is on creating the kind of multi-disciplinary trials that connect disease management, plant physiology, and fruit quality under realistic stress – so that sponsors can move promising concepts toward commercial reality with greater confidence.
 
Let’s design the next generation of disease-resilient programs together
If your team is working on solutions for banana disease management, soil and root health, or tropical fruit resilience, we would welcome a conversation about how our Florida programs can support your development plans.

At Florida Ag Research, we are proud to support the next generation of scientists whose work is shaping the future of agriculture. That commitment was recently recognized nationally when Tanishka Aglave, daughter of our Research Director Dr. Balaji Aglave, received the ​2025 President’s Environmental Youth Award (PEYA) from the U.S. Environmental Protection Agency.

Her project, “Reviving Citrus, Reviving Florida,” explored an eco-friendly solution to Citrus Greening Disease (Huanglongbing, HLB) — the bacterial disease that has devastated Florida’s citrus industry. The work was carried out in Florida Ag Research’s laboratories and groves in Thonotosassa, underscoring the role our facilities play in advancing field-based science.

Promising Results for Growers
Using qPCR diagnostics, chlorophyll analysis, gas exchange measurements, and regression modeling, Tanishka’s trials demonstrated a 63% reduction in disease severity and a 95% improvement in plant vigor with a biological formulation derived from curry leaf extract (Murraya koenigii).

Research showed that this formulation could be used on its own or rotated with oxytetracycline, offering growers both a cost-effective and sustainable tool for HLB management.

Beyond the Science
The project extended well beyond the research plots. Tanishka partnered with the Citrus Research and Development Foundation’s Grove-First initiative, worked alongside USDA scientists and citrus growers, delivered presentations at grower meetings, and authored a children’s book, The Story of Oranges, to raise awareness about citrus health with younger audiences.

In Their Words

Supporting Future Innovation​
​HLB remains one of the most pressing challenges in Florida agriculture. By providing facilities, mentorship, and scientific expertise, Florida Ag Research is proud to play a role in supporting the young scientists whose ideas and innovation will help safeguard the future of citrus.
