The genus Prunus contains economically important species such as cherry and peach, all of which are vulnerable to Pseudomonas infection.

Bacterial canker disease (BCD) has remained one of the most important diseases of stone fruit trees since the 1900s and outbreaks of the disease lead to severe economic losses to growers worldwide.

BCD and blossom blast disease (BBD) of stone fruits are two main phases of the disease.

However, the exact taxonomic identity of the pathogens, which is a species complex, remain unclear.

Due to widespread copper resistance in the pathogens, no viable management tools are currently available.

The long-term goal of this project is to comprehensively understand the pathogen/disease/host interactions to minimize the impact of BCD/BBD on stone fruit production and to provide viable management strategies for growers to improve productivity and increase profitability.

Specifically, a multidisciplinary team from six states will work together in a transdisciplinary way on six interconnected objectives:

1) Unveil the pathogen complex, develop a machine-learning tool for pathogen prediction, and establish a panel of isolates for resistance screening;

2) Determine the molecular mechanism of pathogenesis;

3) Understand the genetics of resistance and susceptibility of hosts;

4) Evaluate the efficacy of chemicals and biocontrol agents as well as tree physiology and make recommendations;

5) Measure the economic costs and benefits of the best management practices; and

6) Develop a comprehensive nationwide program to disseminate practical science-based extension and outreach deliverables.

Ultimately, this will lead to novel control strategies and minimize the impact of the disease.
