Manitoba weed losses and herbicide value in farm study
Len Shebeski of the University of Manitoba reports that perennial weed infestations cut yields and add costs across 137 farms. Wild oats caused up to 25 per acre losses in flax and wheat, with moderate cases yielding net gains from herbicides. The study concludes herbicide spending yields about five dollars back for every dollar invested.
