Florida Ag Research is launching a dedicated research program evaluating the efficacy of biostimulants in Central Florida strawberry production. Candidate products will be field assessed in small plot trials and larger demo plots for marketing support in the heart of the Southeast strawberry growing region. Biostimulant evaluation protocols will measure improvements in:
These investigations will detail effects of application rate, phenological timing, soil or foliar treatment, and almost any other specific product usage scenario for the manufacturer.
Using your protocol or ours, these studies begin at planting in October and continue through the fruiting season ending in March 2026. Plant growth rates, root development, flowering, and fruiting parameters are recorded on populations of treated plants compared to untreated ones. Complete materials and methods, statistical and graphical presentation of data, and interpretation of results are provided in the final report. Florida Ag Research has the capability to apply biostimulant products as a soil amendment, chemigation application, or foliar spray. To capture physiological responses, our trials incorporate advanced measurement tools including the LI-COR® LI-600 Chlorophyll Content Index sensor, NDVI/NDRE sensors, WinRHIZO™ root scanner, and experienced field technicians familiar with strawberry quality standards and measurement. These technologies and staff allow us to quantify crop growth patterns, stress response, and canopy health with repeatable precision. We welcome inquiries from product developers and invite you to connect with our team for more information on our biostimulant program. Florida Ag Research announced a new insecticide screening program for testing ovicidal efficacy against Chilli Thrips for the Florida strawberry industry. Candidate active ingredients include currently registered and new insecticides, acaricides, or other products that can disrupt the pest early in its life cycle. This Fall and continuing through Spring 2026, our Florida entomology team will be conducting focused laboratory and field bioassays that can provide manufacturers with confidential data of a product’s potential utility as a thrips ovicide.
As with other thrips species, Chilli Thrips (Scirtothrips dorsalis) inserts its eggs into leaf tissue where they are protected against most insecticide sprays and biological controls. In this scenario, new larvae continually hatch unchecked, infesting plant canopies and causing direct damage to the harvested crop. In contrast, ovicides strengthen commercial control programs by eliminating a critical pest life stage, which may lead to a reduction in the number of thrips sprays needed, conservation of biological controls, and improvement in resistance management (longevity) of products now in use. In addition to Chilli Thrips, ovicidal efficacy testing is also available for Western Flower Thrips (Frankliniella occidentalis) and several other key insect pests. Florida Ag Research combines state-of-the-art facilities with decades of expertise in entomology, greenhouse and field research, and custom bioassay designs. Our mission is to deliver independent, science-driven insights that manufacturers of ag products can use to refine their portfolios and ultimately contribute to commercial IPM strategies worldwide. Chilli Thrips Control in Strawberry: Comparison of Conventional and Organic Treatment Efficacy5/13/2025
Justification: Chilli thrips are increasing in severity and distribution in Florida’s strawberry industry every year, and reports of severe crop injury are commonplace in all strawberry production districts statewide. In warm fall years, Chilli thrips can become established in strawberry plantings during plant setting periods of overhead irrigations when foliar insecticide spray applications are not possible. Within the first trimester of the crop, most strawberry plantings are infested with rapidly increasing populations of these pests, with injury to foliage, blossoms and fruit evident by mid-season. This occurs despite repeated insecticide sprays or inundative releases of hundreds of thousands of predatory mites and/or beneficial insects. One strategy proposed is to apply insecticides (conventional or organically approved) as early as possible before plant canopies are established and spray coverage limits control. If insecticide materials could be used during the first month of crop establishment, thrips populations could be delayed, and plant damage minimized later in the season. This project seeks to test insecticide application methodologies during the critical crop establishment period under actual field conditions at the Dover lab. Photo 1. Close up of Chilli Thrips (Scirtothrips dorsalis) on strawberry leaf (left) and the feeding damage on infested strawberries rated a 5 on a 0-5 scale (right) Methodology: Three experiments were carried out on naturally infested Brilliance strawberries transplanted in October 2024 at the Dover research station. All three experiments include untreated check plots and a grower standard foliar insecticide rotation.
Treatments: Conventional systemic insecticides
Organic products (1-2 applications)
Data Collection: Thrips counts on ten blossoms per plot were reported weekly. Feeding damage on fruit was rated on a 0-5 scale, where 5 is severely damaged (see photo 1). Early Season Chilli Thrips Counts* on FlowersPre-Plant dips for Cyantranilprole and Imidacloprid had the fewest thrips on flowers in the pre-plant conventional program.
Post-plant Conventional treated strawberries saw the fewest Chilli thrips on standard tank mix program.
Strawberry blossoms treated with experimental organic programs saw higher average Chilli Thrips than the standard and untreated plants.
*Time weighted average count, six week total pressure. Larvae, adult and combined counts analyzed separately Average Fruit Damage % ControlPre-Plant: Imidacloprid as a Preplant Dip controls fruit damage better than standard, statistically (p<0.05)
Post-Plant: Night sprays were significantly less effective than sprinkler or drip applications for experimental treatments (p<0.05)
Organic: No significant differences for standard rotation or experimentals Results: The abnormally cool temps in November and December delayed Chilli thrips establishment until mid-January at Dover. As a result, foliar populations remained very low for the first 5 weeks of the season and comparison of insecticide efficacy during crop establishment was not possible on leaves alone. However, beginning weekly in December, blooms were sampled along with foliage and Chilli thrips were recovered in low but quantifiable densities to compare treatments after plants had set and irrigations stopped. Conclusions: Chilli Thrips populations were low in 2024, limiting the conclusiveness of insecticide efficacy data. However, evaluations based on Chilli thrips presence in blooms and fruit damage indicated that the systemic insecticides Imidacloprid and Cyantraniliprole demonstrated efficacy against both nymphs and adults. Although efficacy was demonstrated rates used for dip and drench treatments negatively impacted plant growth and delayed crop development. The use of insecticide plant dips and drip chemigation methods is not recommended currently due to potential phytotoxicity effects. None of the organic insecticides tested provided observable control under the conditions of this study. Further research is planned for Fall 2025 to determine safe and effective rates for soil-applied insecticides and to reassess efficacy under higher pest pressure.

Explosive Two-spotted Spider Mite Outbreaks – Central Florida. Pest Update: February 20252/12/2025
Two-spotted Spider Mite (Tetranychus urticae) is a persistent threat to the strawberry industry nationwide. Their hidden colonization of plant canopies, rapid reproduction, and ability to develop resistance to chemical treatments make them especially difficult to control. Strawberry growers face significant risks because spider mites damage plants by reducing photosynthesis, stunting growth, and feeding directly on fruit causing significant crop losses annually. With higher than normal temperatures this past month, damaging populations have broken out across Central Florida strawberry plantings and growers are in need of effective solutions to mitigate this escalating threat. Published data developed by Dr. Frank Sances of Ag Metrics Group has shown that an average of 10-15 mites per leaf can cause measurable plant damage and yield loss. The plants shown above have had 100 or more mites per leaf for weeks at a time. Spider Mite Trials: Secure A Spot in Our Spring "Add-On" Program Currently, we are planning the Spring 2025 program at our Dover, FL strawberry research station. If you have a conventional or alternative acaricide in development, our “add on” trial program has openings for additional entries. Foliar sprays, root drench application and drip irrigation methods are possible. Your product will be compared with industry standards for efficacy against eggs, nymphs and adult stages. At this time of year, 2-3 applications are normally made to manage this pest. Join Our Spring Strawberry Program Today The industry is searching for products that can help growers manage the area-wide outbreak and prevent further losses economically important crop. If your product has potential efficacy against spider mites, please give us a call while we are filling slots in our field trial program in Central Florida. The industry is searching for products that can help manage the area-wide outbreak and prevent losses to this economically important crop. Two-Spotted Spider Mite is extremely difficult to control on strawberries and there are few effective control measures available to growers. Field trialing your potential solution in these real-world conditions could benefit everyone involved.

Let's Connect and Talk About Your Hydroponic Trial Needs
Two pest issues are challenging Florida’s strawberry industry with reoccurring crop losses and very few effective and registered controls. The fungal disease Neopestalotiopsis, and the Chilli Thrips (Scirtothrips dorsalis), have become the primary pests of strawberries grown in the southeastern US. Since their introduction, the Florida Strawberry Growers Association has funded several of our annual studies with these pests. Currently, we are planning the Fall 2024 program at our small fruit research station in Dover, Florida. Neopestalotiopsis Trials: Secure A Spot in Our "Add-On" Program If you have a conventional fungicide or biofungicide in development, our “add on” trial program has openings for additional entries. Tractor foliar sprays will begin at crop establishment and continue through the critical Christmas-New Year period. This is when disease episodes are explosive and require repeated sprays to maintain control of fruit infections. Our trials document foliar and fruit diseases weekly and include several commercial standards for comparison with new test products. Trials can be conducted with these reliable natural infestations, or artificially inoculated for greenhouse or open field trials separate from the Dover program. Chilli Thrips Trials: Test Your Product's Efficacy Under Challenging Conditions Chilli Thrips establish immediately after planting despite a month of overhead irrigations for crop establishment. Rain fastness, knockdown efficacy, and systemicity are desirable product attributes during this period. Also, because daily overhead irrigations interfere with foliar applied product efficacy, we are including chemigation and preplant soil drench applications in our protocols with some products. Following crop establishment after sprinkler irrigations are terminated, we use conventional foliar tractor spray applications. Products applied at this time will test efficacy on larvae and eggs, plus knockdown efficacy against adult Chilli Thrips. To summarize, transplant dips, preplant drenches, chemigation via drip tape, and foliar sprays are all possible in our program. As with the Neopestalotiopsis program, we also have Chilli Thrips colonies to populate smaller focused studies in the greenhouse and lab. Join Our Fall Strawberry Program Today If your product has efficacy against Neopestalotiopsis or Chilli Thrips, please give us a call while we are filling slots in our fall strawberry program in central Florida. The industry is searching for products that can help prevent yield losses for this economically important crop in the coming season. There is a lack of effective control measures for both pests so trialing your potential solutions could benefit everyone involved. Please call Balaji Aglave directly at 1(813) 892-1104 or email him at [email protected] or Erin Downey [email protected] to discuss your needs for upcoming Florida trials. For questions regarding trial work at any of our other stations, please contact Brad Booker at [email protected].
