CAT Field Crop Advisory Team Alert Michigan State University's Field Crop Advisory Team Alert Vol. We see these weeds along roadsides from June through September and where burndown herbicides 'missed' these weed species. I have started to get questions on how to control these weeds in fields of no-till soybeans where the soybeans have emerged. I do not have any solutions to this problem. I have listed below some of our common species and some of the characteristics that distinguish one species from another in this family of weeds.
White cockle is a biennial or short-lived perennial weed.
It grows from a coarse root but only reproduces by seed. It has soft, hairy leaves and hairy stems. The leaves are short and broad. By this time of the year it has already begun to flower. It will flower and set seed all summer.
