I am looking for chemicals to control weeds in sunflowers.
What Chemical Can I Use to Control Weeds in Sunflowers?
I'm assuming you want a chemical to spread over the entire bed that will kill the weeds but not the flowers. There isn't one. You can spot spray the weeds with and herbicide or you can do it the old fashioned way, pulling one weed at a time. Either way, you might consider mulching to keep future weeds under control.
