Outreach and Extension
- March 16, 2013: Participated in the IFAS open house fair representing the nematode Assay Lab. The event was attended by county representatives, growers, and researchers. During the event we provided free soil testing service.
- Feb 7- Feb. 18, 2013: We participated at the Florida State fair in Tampa attended by more than 65, 000 people.
- Oct. 19- Oct. 20, 2013: We participated at the Butterfly fest attended by 3200 visitors.
- July 11, 2013 the lab participated at the SVP breakfast buzz banner and poster showcase: We presented the Nematode Assay Lab poster during the event
- In 2013, we reached out to growers and researchers via E-mails, telephone calls and online advice. More than 3500 telephone calls and Email exchanges were made to further strengthen our relationship with clients and researchers.
- The Nematode Assay Lab now offers a sampling service. The sampling service includes a site visit by an Assay Lab employee, soil sample analysis, and management recommendations by an extension nematologist. In 2013, we received sampling and diagnosis request from three growers. In 2014, we planned to expand this service to provide efficient services to our clientele.
- In October 2013, master gardeners accompanied by their mentor visited the Nematode Assay Lab to see how the lab is a valuable resource for the agriculture industry. During their visit, they learned proper sample collection methods for nematode diagnosis, viewed damage specimens displaying nematode symptoms, and methods in nematode threshold functions.
- Master gardeners orientations ( every semester)
- Science fair projects for Floridian 6th graders
- Nematode diagnosis and advise to growers, chemical companies, county extension offices, etc..
