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. Although there was a slow start to the rainy season, this has picked up in the later half of the summer, so we should have sufficient disease pressure to compare efficacy among treatments 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 is also investigating a second formulation of Zinkicide optimized for trunk injection that might facilitate rapid registration. 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.
