1. Please state project objectives and what work was done this quarter to address them:  Objective 1: Production of interstock trees for evaluation in grower plots Interstock grafts have been produced on most of the rootstocks. Some of the rootstock liners growing in the greenhouse were damaged due to a hard to control thrip infestation in the greenhouse which led to malformed leaves and shoots. We have controlled the greenhouse infestation but the grafting work has been slightly delayed due to this issue. It is anticipated that all interstock grafting will be completed in the next quarter.    2. Please state what work is anticipated for next quarter:  All rootstock liners should be stick grafted with the HLB tolerant interstocks in the third quarter of this project.    3. Please state budget status (underspend or overspend, and why): We are on track with the budget spending as funds have been committed for plant propagation.
