Reading Time: < 1 minute

So far in the month of June, 19 winter wheat fields have been surveyed in the counties of Lethbridge, Taber, Warner and Cardston.

Eight fields surveyed in the County of Lethbridge had no signs of stripe rust. Of the six fields surveyed in the County of Warner, three fields had trace incidence of stripe rust (< 1 infected per m2).

While two fields had no signs of stripe rust, one of the fields had an average of approximately four infected plants per square meter with about two percent of the surface of infected leaves having symptoms of stripe rust. Along one edge of this field, incidence was quite a bit higher at about 10 infected plants/ m2  .

Of the five fields surveyed in the County of Cardston, no fields showed symptoms of stripe rust.
