Hoary Alyssum

Notes:

Toxicity to horses has been reported when green or dried forage is contaminated by more than 30 percent. It can proliferate in forage crops, pastures, and rangelands and rapidly fills in areas disturbed or overgrazed. Maintaining healthy stands of vegetation and reseeding after major disturbances are the best ways to prevent establishment. Herbicides are an effective control option, and repeated applications may be necessary to treat plants that emerge throughout the growing season.
