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].

Here, we build on previous work from these and other researchers to develop site-specific “Best Practices” for alternative nematode and pathogenic soil fungi control for Central Florida. Two summer solarization trials took place at the Dover Lab and yields for ASD + Solarization were on par with fumigation. This season we increased precision of applications for manure and molasses and included raised beds or flat ground comparisons.
Flat Ground: In many commercial settings, ASD and Solarization treatments are easier accomplished on flat ground. Here, the chicken manure was applied to the treated area utilizing a cone spreader, followed by mechanical injection of molasses, then the area was disked and plastic mulched.  Methodology
Raised Bed: Planting beds were inoculated with soil-borne diseases, Sting nematodes, and common weed seeds before treatment. Four replicates of five treatments were randomly placed into planting beds previously farmed in strawberries. Following summer solarization/ASD, beds were formed in September (Fumigated) and in October, half of the ASD and Solarization plots with clear plastic were painted black. Flat Ground: Bare ground areas were inoculated with soil-borne diseases, Sting nematodes, and common weed seeds before treatment. Four replicates of four treatments were placed into previously farmed strawberry ground. Each plot comprises one planted bed 120 ft in length. Following summer solarization and ASD plots, beds were formed in September.  Crop Health     Soil Pest Control

The recurring strawberry production challenges of managing soil borne pests in commercial Florida strawberry farms have never been greater. In conventionally farmed operations, increasing regulatory pressures on remaining registered chemical soil fumigants, and the costs associated with their use are important factors that reduce the sustainability of the industry going forward. Also, while still in its infancy, organic strawberry production in Florida is now well established, and the 2022-23 season brought numerous examples of severely impacted plantings from both nematodes and soil borne diseases. To meet the demand for domestically produced winter fruit, Florida’s organic strawberry growers have limited options for soil borne pest control and have come to rely on use of new land, field site isolation, high rates of organic soil amendments, and a variety of alternative organically approved soil pest control products with varying levels of efficacy.
 Metagenomic analysis of 16S and ITS sequencing data of soil microbiome. 1149 features detected across 48 samples. Dendrogram determines similarity across samples. Unsupervised clustering (colors) show sample consistency across seasonal timepoints as well as potential outliers (left samples). Processed data was derived from Mr. DNA pipeline. Final timepoint had the clearest separation in soil treatments indicating high reliability of treatment specific species detection. 2022-2023 Data Review
This presentation brings current performance data from these alternative soil management practices, which includes molecular analysis of effects of treatments to the soil food-web, effects on bedding plastics used in solar heating of soil, and a comparison of yield enhancement and pest suppression efficacy of the methods. Cumulative Yield Comparison
Over the 2022-23 season, the period when soil samples were collected, ASD + Solarization resulted in yields on par with the fumigated plots.
Soil Borne Pest Control
Macrophomina and nematode control for solarized plots was improved by “over the top” and ASD methods. Sting nematode suppression in the ASD and “over the top” treatments were on par with fumigant-treated plots. ASD did have a negative effect on certain brands of clear plastic.

Summary: Management of soil borne pests on commercial Florida strawberry farms has long been a challenge to growers. In recent years, this has been particularly difficult with regulatory pressures on the use of remaining chemical soil fumigants and the costs associated with their use. Also, while still in its infancy, organic strawberry production in Florida has been established by several shippers to try to meet the demand for this strawberry market segment. To provide growers with alternative non-fumigant soil pest management techniques, this project builds on previous work from these and other researchers with an on-site demonstration of Soil Solarization and Anaerobic Soil Disinfestation for the 2023 grower outreach by our collaborative groups. Click Poster to Download  We’re ready for the 2023 research season! 2023 is shaping up to be the largest data generation season on record across the West, Midwest, and Southeast US. The last few years under Covid have brought new pest outbreaks in key cropping systems coupled with an industrywide pent-up demand for R&D data for product developers and growers alike. In response, our company has doubled down on our core capabilities to give our clients the insights they need to accomplish product development goals and drive new value for our farmers. The world has reset–leaving an opening for biology to move in new ways. Over the last three years, we have witnessed significant crop losses across our farming regions. This includes a serious new Thrips / INS Virus / Pythium “Pest Complex” on lettuce in the Salinas Valley of California, explosive Tar Spot outbreaks in the Midwest, and strawberry crop losses from newly introduced Neopestalotiopsis in Florida. These and other agronomic challenges surfaced during Covid and have kept us busy working to understand their epidemiology and uncover new opportunities for control.
 Frank Sances, President To meet this demand, Ag Metrics Group has significantly increased facilities, professional staff, and methods development to offer an expanded portfolio of experimentation for our sponsors. Research capabilities added this year include five new climate-controlled greenhouses for California and Florida. In Michigan, we built 4,800 sq. ft. of new Entomology and Nematology laboratories, surrounded by 80 additional acres of premium irrigated farmland. All told, Ag Metrics Group has grown to 12 science laboratories, 70 full-time staff, and several hundred acres of company-owned farms in key agricultural regions of the American West, Midwest, and Southeast. Our client base includes most all ag-product manufacturers, many regional grower cooperatives, and governmental agencies that include state universities and the USDA. Now more than ever, we recognize the critical impact data-driven product development has on our industry. These solutions enable growers to respond to new challenges and opportunities with confidence in the stewardship of their land. Privatized science is the key to rapid and robust biological insights to demonstrate value in a dynamic and diverse set of pest and environmental applications into the future. We look forward to our continued partnership with our clients and wish you all a very successful year. Frank Ag Metrics Group Provides “First Report of Neopestalotiopsis rosae Causing Crown and Root Rot of Strawberry in California” American Phytopathological Society of America (APS) Dan Lawrence 1, Greg Brittain 1, Balaji Aglave 2, Frank Sances 3 1 Pacific Ag Research, 2 Florida Ag Research, 3 Ag Metrics Group Following these authors’ research in Central Florida strawberry plantings in late 2019, they found this devastating fungus again in Salinas, California, on newly transplanted strawberries in the winter of 2021. Since their original Florida research, the fungus is now well established throughout the Southeast and has become the key pest for this crop early season. This subsequent finding in California is the first scientific proof that it has moved westward into other US strawberry producing areas, and has the potential to cause crop losses to growers in that region. Turf & Ornamental Capabilities Expanded Companywide in 2023
California Adds 5,400 sq. ft. of Greenhouses
New San Joaquin Valley Field-Lab at Our Five Points Station In 2022, we remodeled 1,200 ft2 of administrative offices, opened a new 2,500 ft2 climate-controlled field lab, and installed additional fruit, nut, and vine plantings. We added more microscopy, a walk-in cooler, a post-harvest drying unit, and a deep well with a new reservoir for sustainable water at this site going forward. The past year we purchased more off-site equipment including a new tow vehicle, support trucks, and another mobile orchard sprayer platform for off-site trials. Together with a new research biologist, these assets comprise a well-equipped and staffed Central Valley research campus with a wide geographic radius of field activities for product development needs. Michigan Ag Research Expansion in Final Stage of Completion To advance our goal to provide the best possible administration and science campus at Albion, Michigan Ag Research is now in the final stages of construction of a 4,800 ft2 building that will include:
In addition to the new laboratory facilities, 80 acres of irrigated farm land were added, bringing the total station size to 200 acres. Publicly Funded Research: |
