In 10 of the 13 trials, double-nozzle configurations provided a 15% reduction in disease severity and up to a 60% increase in yield compared to the untreated control. However, droplet size and angle of application had no effect on field pea yield. Moderate water volume...

Application of foliar fungicides at the 2 to 4 leaf stage reduced blackleg disease incidence and severity, and improved yield on the susceptible Westar canola cultivar. On two resistant cultivars, however, this fungicide treatment reduced the disease but showed no yield benefit. Since resistant canola...

When stripe rust severity was low, resistant and intermediate wheat and barley varieties did not suffer significant yield losses. When leaf spot and stripe rust disease levels were high, a foliar fungicide application was necessary to reduce yield losses even on resistant varieties. Seven spring wheat...
