Alkaline soil promotes soil fungus

Verticillium is more severe when pH is 7.4 to 8.6, according to Alberta research

WINNIPEG — Verticillium stripe is a more common and troublesome disease for canola growers on the eastern half of the Prairies, particularly in Manitoba. Meanwhile, verticillium isn’t a huge issue in Alberta. There may be a simple reason for this geographic variation — soil pH. Researchers at the University of Alberta have learned that Verticillium […] Read more

Researchers study verticillium yield losses

WINNIPEG — For a few years, canola industry leaders have been worried about verticillium stripe and its impact on crop yields. Reports out of Europe suggest the fungal disease could cause a wide range of losses, anywhere from 10 to 50 percent on oilseed rape. However, the extreme losses are usually confined to a tiny […] Read more
