1. Please state project objectives and what work was done this quarter to address them: Objective 1: To compare different rates and annual use patterns of trunk-injected OTC on late-season (Valencia) and early-season (Hamlin) sweet orange tree and their effects on health, yield, and fruit quality over a period of 3 years in a commercial citrus production environment.Obective 2: To compare spring with late summer injections in Valencia orange trees to determine if OTC effects on yield can be enhanced, and the harvest window extended, through timing of injections. Trees were monitored. No phytotocicity was obserevd after the spring injections. Fall injections were conducted in September in the Valencia trial. No phytotoxicity was noted. 2. Please state what work is anticipated for next quarter: We will conduct tree measurements. Leaves will be collected for CLas assessment. In the Hamlin trial fruit will be collected for fruit quality assessment, and trees will be harvested. Tentative harvest time is middle of December. 3. Please state budget status (underspend or overspend, and why):The budget is as expected.
