This project addresses the number one priority issue in the 2018 AILRC survey: Disease Control and Management. Fusarium wilt of lettuce caused by the soil-residing fungus Fusarium oxysporum f.sp. lactucae (fol) has increasingly become a problem in iceberg lettuce in Arizona, causing significant losses in early season iceberg lettuce crops.

Fusarium wilt of lettuce field trial

Since 2015, The Yuma Center of Excellence for Desert Agriculture (YCEDA) has managed Fusarium wilt of lettuce field trials evaluating commercial and pre-commercial lettuce cultivars for resistance to Fusarium wilt, chemical and biological crop protection products for disease suppressing activity, and cultural management methods.

Fusarium wilt of lettuce continues to be a growing threat to the competitiveness of the Arizona iceberg lettuce industry, and unlike most plant diseases, there is no known treatment to control this soil-borne disease completely.  The Yuma Center of Excellence for Desert Agriculture (YCEDA) is leading multiple projects conducting research to find solutions to this plaguing problem.  The objectives of this project were developed based upon findings from our 2016 study, “Advancing Fusarium wilt management in lettuce",  which revealed the need for more precise and reproducible methods for inocu

Prior to submitting the proposal, Lettuce Fusarium Wilt Trials and Analysis, to the AZ Department of Agriculture's Specialty Crop Block Grant Program, YCEDA convened a meeting with members of the production Ag industry to receive guidance and ensure the research would address industry needs. $69,000 was awarded to continue efforts to mitigate Fusarium Wilt of lettuce. 

October 2016 FW Conference in California

A 2016 Fusarium conference for researchers and industry was held in the Salinas area to advance the priority suggestions from the 2015 symposium. Breakout sessions focused on future research projects and field evaluation of resistant varieties and crop protection products. Attendees were able to tour the area's lettuce industry and research institutions.

2016 FW Field Trials

Nearly $70,000 in funding from the Arizona Department of Agriculture Specialty Crop Block Grant Program allowed us to continue field trials of crop protection products as well as research early and remote disease detection.  UA researchers Dr. Barry Pryor and Dr.
