During this 5th quarter of the Project our work continued without problems. Objective 1: We continued monitoring parameters including tree trunk diameter (rootstock and scion) and canopy areas. Some differences are starting to emerge in trunk diameter, although not statistically significant yet: Covered trees are starting to show bigger diameters in both rootstock and scion. All IPC-covered trees are still HLB-negative. We are continuing documenting canopy area expansion by photography and also by leaf are index measurements after replacing the old 4-ft IPCs with new 8-ft covers, donated by The Tree Defender, Inc. Objective 2. We have finished planting the 700 trees of SugarBelle, Tango and Early Pride mandarins, and we started to monitor regularly tree parameters (trunk diameter, and leaf sampling, for CLas, chlorophyll and sugar analysis). Objectives 3 and 4. We set up blooming and fruit development experiments this season inside the IPCs and in our CUPS facility, which is now fully operative. We have performed deficit irrigation to induce blooming in both IPC and CUPS this season. We are currently collecting data on these experiments. Outreach, Professional Presentations and Extension Activities for this quarter : – A CUPS Day.CUPS, mini-CUPS and other strategies to manage HLB. Talk on “Individual Protective Covers” . SWFREC, was delivered on Dec 17. 45 people registered, 44 attended. Impact: 100% of the attendants found the presentation useful and manifested a gain in knowledge. Half of the attendants will improve their management practices, which, in this case, may mean to adopt IPCs. In addition, 32 CEUs and 10 CCAs were certified. -As a follow up of the International invited seminar at IVIA, Valencia, Spain entitled “Living with HLB. The new reality of Florida Citriculture” that was presented by Fernando Alferez last December 4, 2019, the spanish professional magazine Phytoma published an article showcasing, among others, our IPC work.
