As you're thinking about winter weed management in alfalfa production, keep in mind the need for common groundsel control.
Groundsel (Senecio vulgaris) is highly toxic to livestock at all growth stages because it contains pyrrolizidine alkaloids (PA) which can cause chronic and irreversible liver disease in animals. Cattle and horses are most sensitive to the PAs, followed by pigs and chickens, and then sheep, goats and turkeys, which are the least sensitive to PA toxicity. Younger animals are typically more sensitive than adults. Therefore, the identification and control of groundsel in forages is important for preventing livestock PA poisonings.
