Extract

Tansy ragwort (Senecio jacobaea L.), commonly called stinking willie and sometimes incorrectly called ragweed, is an abundant weed in many parts of Prince Edward Island and Nova Scotia. It is found in pastures, hayfields, waste areas, clearings in woodland and along roadsides. This species is extremely poisonous to cattle and horses and thus is a problem in pastures.
