Field experiments were conducted in lggl and 1992 at Morden, Mani toba, on the efficacy of eight fungicides to control sunflower rust. Fungicides were applied either once at flowering or twice. at flowering plus 2 weeks later. Two applications of mancozeb resulted in the highest reduction in rust severity over the two years of this study followed by two applications of propiconazole.One application of mancozeb or propiconazole significanily reduced rust severity over the two-year period. One and two apprications of fluazinam, and two applications of chlorothalonil significantly reduced rust severity in 1991; while one and two applications of myclobutanil, and two applications of RH-7592 significantly reduced rust severity in 1992. Most fungicides increased yield over the control, however, significant increase in yield resulted only from one application of myclobutanil or benomyl in 1991.
