I’d be fascinated to read more about that second part

They mimic a growth hormone: https://en.m.wikipedia.org/wiki/Auxin https://en.m.wikipedia.org/wiki/Auxin Between application time and death the plants really do just grow out of control in weird uncoordinated ways. You can see a treated dandelion here: https://turf.purdue.edu/wp-content/uploads/2015/03/Slide16.JPG https://turf.purdue.edu/wp-content/uploads/2015/03/Slide16.J... Another interesting broadleaf herbicide mechanism is overloading invasive plants with chelated iron. Broadleaf weeds absorb iron rapidly and without regulation until the point of toxicity, whereas grasses will only absorb what they need to turn a nice healthy dark shade of green.

    That image makes me appreciate just how slowly most plants grow and move. Imagining that bundle of dandelions writhing around triggers the same sort of visceral reaction as seeing maggots for me.

      If it’s any consolation that picture was probably about a week after treatment, so still quite slow! The entire process takes about two weeks depending on the type of plant.
