In recent years, wheat midge has caused yield losses to fields across the prairie provinces, and has been blamed for wheat quality losses as well, including: aborted kernels, feeding lines and bran rupturing.
So we know wheat midge is a significant pest, but did you have any idea that once anthers are present, the plant is no longer susceptible to midge damage? In this episode of Wheat School, John Gavloski, provincial entomologist for Manitoba Agriculture, Food and Rural Initiatives, talks about the chemical that wards off larval feeding, and how it relates to midge-tolerant varieties. Gavloski also describes how economic thresholds vary depending on whether a producer’s priorities are yield or quality, and much more.
