Pasmo disease of flax is widespread in
Manitoba. It reduces the yield and quality of harvested seed, thus
negatively affecting the health food market of flaxseed. Pasmo also reduces
the yield and quality of the fibre in the infected stems, resulting in
reduced interest of the industry and a lower market value of the straw from
infested fields.
This study will investigate the epidemiology of
pasmo in flax, including the over-wintering of the fungus, the source and
timing of primary inoculum in the spring, and the disease development during
the growing season. Flax accessions will be screened to identify sources of
resistance to this disease. The applicant will also investigate the
efficacy of fungicide applications as a short-term control measure of this
disease. The overall benefits of this project are the reduction of
production risks to the growers and a better quality of seed for the
consumer.
Dr. Khalid Rashid of the Morden Research
Station, Agriculture and Agri-Food Canada is a co-applicant of this project.
The Pembina Valley Development Corporation is a
funding partner.
