Control of orange rust in sugarcane with fungicides

Staier, T.; Magarey, R.; Willcox, T. G.

Orange rust an important leaf disease, has caused significant yield losses of up to 40% in the highly susceptible variety Q124 over the past three years. The disease caused the greatest losses in the central and southern cane-growing regions of Queensland, Australia. Fungicide experiments were conducted over a two-year period in the central district. Four fungicides were applied at six sites in varying combinations and schedules to provide a range of disease control strategies.
