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 to confirm the results and test the consistency of control is well underway. Rainfall through the beginning of the summer at the field trial site was minimal. Without further rain later in the season there could be insufficient disease pressure to assess canker control. 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. He has also begun investigating possible registration and commercial production.
