DATOC was requested to provide a report
summarizing research done on Early Detection
Technologies which was funded by the Citrus Research
Board and HLB-MAC. The report is to include explanations of each technology, economic concerns, diagnostic accuracy, and more.
In 2017 DATOC produced a briefing paper that summarized the history of the development of the HLB epidemic and expansion of ACP. DATOC is working on an update to the document and to update it regularly from now on.
Distribution of leaf material in pilot program
The CDFA recently implemented a pilot program which will allow citrus growers to utilize grates as an alternative mitigation strategy for disinfesting loads of bulk citrus. DATOC is analyzing the results of this program to help inform a recommended sampling plan if the grate systems are adopted on a wider scale.
Restructuring survey activities
The CPDPP continually strives to utilize its resources in the most efficient manner possible, by incorporating the information gleaned from new data as it arises. Currently, the program's survey activities are directed by the results of a Residential Risk-Based Model (RBM). However, a Commercial RBM also exists and is available to help guide activities. This project will look at the best way to implement a hybrid approach of both models.
Hot spot cluster analsyis
Dr. Dave Bartels of the USDA has previously provided cluster maps to various groups. DATOC will be assuming responsibility for the production of these maps to provide the CPDPP committees with on-going analysis of the epidemic, to help with resource allocation decisions.
Analysis of residential program
DATOC has been requested to analyze CDFA's program activities combating HLB in Southern California for efficiency and effectiveness.
Density of new infections
As a part of DATOC's report on exposure to CLas in Southern California residential areas, we reported on the spatial density of HLB cases in all of Southern California up to May 2018. DATOC was then asked to evaluate this over smaller geographic scales. We are also evaluating the changes in infection density in the most recent detections.
Exposure on repeat properties
DATOC has previously reported on exposure to CLas in Southern California residential areas. We have since been asked to look at exposure on properties where CLas has previously been detected.
Time series analysis of ACP
The presence of ACP in California has been tracked by various programs and projects for several years. This analysis will construct a time series for various California regions since the start of these activities.
