Manitoba rust diseases dissipate as fusarium appears

CNS is reporting that . . .

The spread of leaf and stripe rust in southern Manitoba appears to be over.

The diseases, which generally target cereal crops, were thought to have blown up from the northern U.S. in late spring. Fields near Carman and Killarney both tested positive for rust in winter and spring wheat.

Recent warm weather, however, appears to have dealt the two rusts a deadly blow.

“Not with this heat — rust doesn’t enjoy 30 C days, even though we’ve had precipitation; it’s just been too hot,” said Pam de Rocquigny of Manitoba Agriculture, Food and Rural Development in Carman.

She credited producers in the affected areas for scouting fields and applying fungicides where needed, as the main reasons for the diseases’ departure.

The ag department’s focus now shifts to fusarium head blight, she said, as now is the time the crops traditionally show symptoms.
