It is distinguished from cow cockle, bouncing bet and bladder campion by its hairy leaves and stem. Bladder campion is a perennial and can reproduce through seeds and vegetatively. As white cockle seed is similar in size and shape to clover and alfalfa seed, it is often a contaminant. Management: Early postemergence herbicide applications improve control. IWM relies on the combination of a variety of methods such as chemical, biological, mechanical, and cultural controls as well as overall preventative measures.
