Goal – Identify almond cultivars with resistance to the most aggressive causal agents of wood-canker diseases of almond: Band canker and Lower limb dieback.
Activities – Compared virulence of two Neofusicoccum species inoculated to the woody stems of potted almond plants.
Results & Outputs
Peerless was the most resistant to both species of the pathogen. Carmel, Sonora, and Padre were among most susceptible, with some differences depending on the species. Susceptible cultivars had the highest mortality. Cankers were so severe in Sonora that 50% of the trees died after 10 months. This means that infections of young trees, esp. of susceptible cultivars, must be protected in young orchards.
Significant Outcomes & Impacts
Now that we know the causal agents, we must identify preventative practices.
