Most cases of livestock poisoning occur after the animals have consumed hay containing dried parts of jimsonweed. Hence, it is imperative to completely remove this weed from pastures or meadows, especially before making hay. Management Proper sanitation and prevention are ideal ways to control this weed. Hand pulling, hoeing, and other mechanical control strategies work well if the infestation is isolated. Chemical control is warranted for instances of high weed pressure or widespread infestations.
Chemical control is most effective during spring months when the weed is actively growing.
