New Technology to Prevent and Suppress Pierce's Disease...being researched in New Mexico
Some of you may have seen the news article ..and some of you may not have. But last September, Wine Business Monthly https://www.winebusiness.com/wbm/ ran an article by Mr. Ted Rieger,
that reported a new technology being researched and applied to suppress and possibly cure, Pierce's Disease in grapes. This work was conducted by a biotechnology start-up located in Santa Fe, NM. The work garnered grant support ($448,000) from the California Department of Food and Agriculture (CDFA) Pierces's Disease and Glassy-winged Sharpshooter Board and trials have been conducted in Sonoma County, CA. The work is centered around the application of peptides that apparently can defeat the causal organism of Pierce's Disease, the bacterium, Xylella fastidiosa, via topical applications of the peptide to infected vines in the field.

| Grape leaves with Pierce's Disease 'like', symptoms. These leaves display leaf margin necrosis and some chlorosis with a red colored "eye-liner" like margin toward the interior of the leaf. This DOES NOT indicate the vines in question have Pierce's Disease...BUT it is one symptom that points toward a possible infection. |
