This week's update is a carbon copy of last week - the fields are all but void of disease and pests of any kind, and growing conditions are near-ideal for small grains with intermittent but spotty rain showers. Therefore, the advice remains the same as last week.
Oats - If you did not apply a fungicide to control crown rust when the flag leaf had just fully extended, apply a fungicide at Feekes 10.5 (fully headed) to protect the crop against crown rust for the remainder of the season. There is little incentive/need to switch to a premium fungicide to also try to suppress FHB, given that the overall risk appears to be relatively low
Spring barley - Apply a fungicide at Feekes 10.5 (fully headed) to suppress FHB and control net blotch on varieties rated susceptible or very susceptible to net blotch. There is little incentive to use one of the premium fungicides to suppress FHB.
Winter wheat - Apply a fungicide at Feekes 10.51 (beginning of anthesis) if you find either tan spot or Septoria present in the lower canopy or if your variety is rated very susceptible to FHB. There is little incentive to use one of the premium fungicides to suppress FHB.
