As noted in the last report, the experiment was established to meet the early objectives to obtain the trees and establish the primary infections with HLB and citrus nematode. We anticipate being able to begin testing trees for HLB in June.The trees in this experiment were maintained with irrigation and fertilization in a screenhouse. This was a fortuitous experimental schedule, because the potential to conduct research did not exist due to the UF response to the global pandemic. Nematode and CLas infection rates will be determined in the next reporting period and, if satisfactory, plants will be arranged in a randomized design for a one-month period of growth prior to the evaluation of treatment effects.
