Innovative Technologies for Pierce’s Disease [2023]

OVERVIEW

This is a presentation of a field trial to develop a range of efficacious biopesticides for commercial application against Pierce's disease (PD). This project focuses on field testing of natural biological products for control of PD. Biological products are microbes that live in association with plants. Our research groups isolated biocontrols, both bacterial and bacteriophage-based, from agricultural samples, including grapevine wood. Bacteriophages are viruses that selectively infect and kill bacteria but do not infect plant or animal cells. This research aimed to generate the data needed for commercialization of new biopesticides that can be used by grape growers to manage PD.

XylPhi-PD is EPA approved and OMRI-listed.

Initially approved in California, XylPhi-PD is now registered in the following States: Texas, Arizona, New Mexico, Tennessee, Alabama, Georgia, North Carolina and Virginia.
