The canker field trial of Zinkicide compared to industry standard management on grapefruit showed better control of canker on fruit than all other treatments. We also observed control of some fungal pathogens. A second year of this field trial used a half and quarter rate of Zinkicide compared to the previous year. The half rate provided equivalent canker control to copper, while the quarter rate started to show reduction in canker control. Analysis of the data from the nanoparticle and non-nanoparticle version of Zinkicide gives insight into possible systemic movement. Dr. Santra’s group has improved synthesis of Zinkicide to reduce the amount of some ingredients needed for synthesis while maintaining efficacy. This improvement is aimed at reducing cost of production. The research team continues working on commercial production and registration for canker although the time line for registration is still too preliminary to accurately predict.
