Do fungicides used to control scab help control ergot?
Chemical control of the ergot fungus (Claviceps purpurea) has been investigated in Europe, but with limited success. NDSU has no local information on the effect of fungicides such as Folicur or Tilt on the ergot fungus. It is not expected that these fungicides, which were used to suppress scab this year, would have much effect on the ergot fungus. 2003 FINAL CEREAL RUST BULLETIN, USDA, ST. PAUL, MN The final edition of the 2003 Cereal Rust bulletins, published by the USDA Cereal Disease Laboratory, St. Paul, stated that: a) Wheat leaf rust was widespread this year and severe in some areas of the US. The bulletin states that trace to 60% leaf rust severities were observed in spring wheat varietal plots in central and eastern ND plots, and up to 40% severities were observed in some ND commercial fields. The spring wheat cultivars currently grown have less effective resistance to leaf rust than those that were popular 10-15 years ago. b) Wheat stripe rust developed early and was more seve
