Key Result

This project is still in progress, but is aimed at mitigating the threat posed by verticillium stripe to sustainable canola production through a variety of research activities.

Project Summary

Purpose

To determine the effects of growth stage and inoculation techniques on host infection, and to evaluate the effects of disease severity on plant growth and yield at different inoculum concentrations.

Objectives

This project is an integrated and collaborative approach to addressing the major research priorities around verticillium stripe in Canada. It includes four specific objectives:

1) To examine the relative virulence of V. longisporum and V. dahliae on commercial canola cultivars.

2) Determine the effects of growth stage and inoculation techniques on infection.

3) Evaluate the effects of disease severity on plant growth and yield at different inoculum concentrations.  

Progress

Greenhouse experiments on the effect of different inoculum densities on plants at different growth stages are being evaluated. Despite COVID-19, field experiments on the effect of different inoculum densities on disease severity and yield were seeded and are being collected.
