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.

Yesterday we were in Dover, Florida, at the Florida Strawberry Grower Association & UF/IFAS Tailgate. Frank Sances presented updated data on Combining Soil Solarization with Conventional Chemical Fumigants and Anaerobic Soil Disinfestation (ASD) in Florida Strawberry Production.

Introduction
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.

Methodology
Planting beds were inoculated with soil borne diseases, Sting and Root Knot nematodes, and common weed seeds prior to treatment. Four replications of six treatments (Table 1) were randomly placed into planting beds previously farmed (2021) in strawberries. Each plot comprises two planted beds (4 plant lines), 40 ft in length (8 ft x 40 ft plots, 320 ft²), in a randomized complete block (RCB) experimental layout. Following summer Solarization and ASD plots, beds were reworked in September, standard fumigation applied to comparison plots, and all plots planted and grown conventionally to maturity on October 15, 2022. Data collection for pest control and yields have begun. AOV with LSD Means comparison, α=0.05.

Frank Sances will be attending the 2022 MBAO: Fumigation and Alternatives for Production, Storage and Trade Conference in Orlando. Come find out about our "Efficacy of Solarization and Anaerobic Soil Disinfestation" study. Email us to have a meet-up or a pre- or post-conference tour of our Florida Station, less than 2 hours from Orlando. #anaerobicdisinfestation #strawberry #MBAO #Methylbromide #FloridaAg #FloridaAgResearch info@agmetricsgroup.com

Florida Ag Research presented a “Proof of Concept” field demonstration intended to evaluate the suitability of using solar radiation to enhance soil borne pest control with Conventional Fumigants and Anaerobic Soil Disinfestation in commercial Florida strawberry production. Potential benefits of the system include:
 
a) Solarization and ASD are approved organic soil pest control options
b) Solarization with conventional soil borne pest control inputs may allow reduction in chemical usage
c) ASD is a potential waste recycling system

​The project, which began in June of 2021, was published by Florida Ag Research/Ag Metrics Group scientists and growers: Frank Sances, Balaji Aglave, Mark Keeley, Kaleb Williams, and Charlie Boone.
 
The Solarization Project was presented by Ag Metrics Group’s Mark Keeley (formerly a Station Manager of Florida Ag Research). “It was great to come back out and present this exciting work to growers and researchers since the ‘Field Day’ was cancelled last January,” said Keeley, “And a great opportunity to introduce Mariano [Galla], the new Florida Ag Research Station Manager, to the Florida strawberry grower community.”
