I remember learning when they 1st discovered a weed becoming resistant a little over 20yrs back, from memory it was 1st detected in a ragweed (can't recall if the Canadian or annual), it changed how we approached some things doing bush regen
just had a vague recollection of how it became resistant, some seeds are strong enough or had developed just enough, that they were still viable, even though drenched in herbicide, every time that happened, the plant built up the resistance
Yes, herbicide resistant is a very interesting field to study. Certain types of Amaranth (ie Palmer Amaranth) have been very prominent in the realm of herbicide resistance over here (among other plants). Amaranth has been becoming immune to glyphosate, by a couple different mechanisms. That is an interesting, I had not heard of the ragweed resistance, thanks for sharing!

You really know your stuff. Great video! Extremely informative.
