How to remove sand burr's

Asked March 25, 2020, 10:45 PM EDT

I just purchased a lot in Montrose, CO and find out the lot has sand burr's everywhere, how can I kill those plants? And, any thoughts how to rake them up?

Just to confirm, this is a grass with picky seed heads. If so, this is an annual so an application of a pre-emergent like Pendulum would work. here is an article on it.
http://adams.colostate.edu/ag/sandbur.htm Depending on how rough the ground is, if there were anyway to mow it, collect it and then dispose of thru serious composting (140-160 degrees) or hauling off so you don't have the seeds coming up this year. Raking might just spread. Or plant something like a cover crop that could overgrow it. https://drylandcovercrops.agsci.colostate.edu/2018/06/07/technical-bulletin-now-available/ Or if watering/irrigated: https://cmg.extension.colostate.edu/Gardennotes/244.pdf
Good luck.
