Abstract
Four triazole fungicides cyproconazole (50 ppm), propiconazole (250 ppm), triadimefon (750 ppm) and triadimenol (250 ppm) applied as foliar sprays at 14-day intervals significantly reduced naturally occurring brown rust infections on sugarcane leaves in 1996. In trials undertaken in 2002/03 and 2003/04, triadimenol applied on varieties NCo376, N14 and ZN6 provided only partial rust control, with mean disease ratings in the most susceptible variety, ZN6, falling from 37% leaf coverage in unsprayed to 16% in sprayed crops. Cane and sugar yields of ZN6 increased by 18% and 16% respectively in 2002/03, but there was no increase in 2003/04. Cane and sugar yields of the more resistant NCo376 and N14 varieties were not affected by brown rust in both trials.
