Weed lasers would be a welcomed implement. In my county they estimate a large percentage of the viable agricultural output is lost due to foreign and domestic invasive plants overtaking grazing and cultivated land. You have to work really hard to feel like you are breaking even if you are not willing to nuke with 2-4D every spring and fall.
Some plants (even native/noninvasives. looking at you Lupine…) cause serious harm directly to livestock, or reduce the carry ability of the pastures (mustards, St. John’s wort) to get livestock to late fall without eating the hay you cut in the summer that might have a cluster of hoary alyssum which will make your horses sick. Some, you may just have to make your peace with (Canadian thistle).

Plants are scary.
