what will kill it but not the clover? This plot is one I planted last spring with imperial clover. It has come back nicely but it had some grasses and this stuff in it. 2 weeks ago I hit it with Vantage and that wiped out ALL the grass leaving only the clover and this yellow plant. The clover is doing great but this yellow stuff is starting to over take it. Please let me know what you think it is and what will kill it leaving me a beautiful clover field. Thanks for all you help.
