Abstract
The duration of control (days after sowing that the disease severity reached 10%) of stripe rust of wheat with triadimefon- or flutriafol-coated superphosphate, applied at seeding, on a susceptible wheat cultivar, Bindawarra, was determined in field experiments. Both fungicides were equally effective and rates of application ≥100 g/ha protected plants for 17–19 weeks after sowing regardless of the timing of the onset of the epidemic. This protection was associated with yield increases ranging from 23–60%, depending on the onset of the epidemic and rate of fungicide application.
