Yes, you can use your cattle to control weeds
When former BEEF columnist Jim Gerrish moved from Missouri to Idaho, he encountered a situation that took him by surprise—a legal mandate to control noxious weeds. Among the perpetrators in the area was spotted knapweed. He tried spraying and he tried just letting the cattle eat whatever they would. But the problem got bad enough that he decided to be more proactive before county officials moved in and took over, he writes in onpasture.com.
“A quick read of the existing literature on grazing for knapweed control suggested the window of opportunity for making a meaningful impact on the weed was between early bud and full bloom. The research said knapweed grazed severely during mid to full bloom experienced over 90% reduction in seed yield. In the past we had started our grazing while the knapweed was in a vegetative state and never delivered enough grazing pressure to force the cattle to eat the knapweed once it began blooming. “
