Introduction and Global Impact

This article was published as a means to inform growers about a fungal disease that would affect their wheat crop. Before fall planting is the best time to consider the best methods and identification of which varieties are the best in the area.

The data being from all over Michigan will allow for optimal decisions made by the farmer for their farm. The potential damage of having a susceptible crop is 40% according to the article. On a global scale that adds up to a lot of bushels not making it to the table.

Survival & Infection

In a disease cycle there is a survival stage. For wheat rust that appears in Michigan the spores of the fungus blow in from the south where they overwinter.

In order for good development the right conditions must be met and those are:

  1. Wet soil
  2. Cool temperatures
  3. Optimal Temperature 50 to 59 degrees Fahrenheit

The infection court, or how infection happens, is in the stomata. This is an opening that the plant uses respiration. Signs may not show up for 2 weeks but when they do they will be orange in color.


Since it is a fungus the best treatments is a fungicide or select a resistant variety to plant if you are excepting problems. From a management prospective it would be best to make sure, if planting wheat after wheat especially, that there are no vectors for harboring inoculum. Reducing volunteer wheat and not having to worry about infected seed helps manage fall wheat stripe rust in Michigan
