摘要

Orange rust, an important leaf disease, has caused significant yield losses of up to 40%rnin the highly susceptible variety Q124 over the past three years. The disease caused therngreatest losses in the central and southern cane growing regions of Queensland.rnFungicide experiments were conducted over a two-year period in the central district.rnFour fungicides were applied at six sites in varying combinations and schedules tornprovide a range of disease control strategies. Orange rust in susceptible varieties can berneconomically controlled if fungicide is applied when a high-yielding crop is expected,rnfungicide application occurs early in the infection cycle, a high percentage of the leafrnarea is affected, the correct fungicide is selected and sugar price is greater than $A300.rnThe planting and cropping of resistant varieties will be the main disease control strategyrnfor this disease.
