sand burrs

[Stephen Tashiro]

I've read that sand burr weeds can be controlled by spraying an area with a chemical that prevents their seeds from germinating. What commercial product works well?

[Steve Rozmiarek]

Depends on what sandbur you have. Puncturevine and an actual sandbur take different chemical. Post a pic of one of the burrs if you want help with the id.

Green Light® Amaze® Grass & Weed Preventer. It's a granular application for pre-emergence control.

I posted photos of the burrs on photobucket: http://s716.photobucket.com/user/tashirosgt/library/Sand%20burrs?sort=3&page=1

Conrad 's recommendation will work on those, it also has two active ingredients, which gives two mode of action control, which is usually a good thing. It is preemerge, so it won't do anything for growing plants.

They are field sandburrs btw.
