1. Please state project objectives and what work was done this quarter to address them: Main objective: To determine the large-scale efficacy of trunk injection of OTC on citrus tree health, fruit quality, and yield in existing rootstock trials in three different commercial growing environments. Sub-objectives: a) test the efficacy of OTC injection in the rootstock trunk compared to injection into the scion, and b) determine whether OTC injection increases/restores root densities and if there are interactions with the rootstock. Leaves were collected for CLas analysis. Trunk injury/wound evaluations were conducted. PCR analyses were continued. Statistical data analyses continued. So far, data analysis showed the following: The uptake rate of the injected OTC solution (Rectify) did not differ whether injections were done into the rootstock or the scion trunk. However, there was a large variability during the day and among the trial sites – the uptake rate was anywhere from <30 minutes to >3 hours.Injections in the rootstock seemed to have caused slightly less visible injury than injections in the scion. Some rootstock differences were also noted.In one of the trials (Venus location), we measured lower CLas titer levels in injected trees. 2. Please state what work is anticipated for next quarter: Leaves will be collected for CLas and OTC analysis. Disease ratings will be conducted. We will prepare for the harvest. Harvest dates will depend on the grower collaborators. 3. Please state budget status (underspend or overspend, and why):The budget is as expected.
