DAPHNE SPP Alternative Name: Daphne Toxicity to Goats: Toxic, high risk Toxicity to Other Species: All livestock species Palatability: Not known to be eaten Poisonous Principle: Macrocyclic diterpenes, notably daphnetoxin and mezerein, together with dicoumarol glycocides, notably daphnin Effects: Signs and symptoms; Vomiting, diarrhoea sometimes haemorrhagic, extreme weakness and depression. Health and production problems; Rapid death. Integrated Control Strategy: GARDEN PLANT Prune out carefully into disposable bags. Do not feed this plant to any livestock. Comments: All parts of the plant are toxic, but especially the berries and bark. Use gloves, as this plant can cause a rash on the skin of unwary humans. Historically used in the treatment of venereal and scrofulous diseases. No 214 Daphne spp CORNELL UNIVERSITY 29
DATURA STRAMONIUM Alternative Name: Thornapple, false castor oil, jimson weed Toxicity to Goats: Toxic, high risk Toxicity to Other Species: Toxic to cattle, sheep, horses, pigs and poultry Palatability: Not known to be eaten Poisonous Principle: The tropane alkaloides, hyocine, scopalamine, and atropine Effects: Signs and symptoms; Constipation and infrequent urination. Some initial excitation with later depression, muscle trembling, weakness leading to an unsteady gait and eventual recumbency. Dilated pupils, dry mouth and nose, an increased heart rate but a weak pulse, loss of rumen sounds and laboured respiration. Some cases may progress further to either coma or terminal convulsions. Health and production problems; Death in some cases within 12 hours of first signs, but many cases may recover with no long term effects on their productivity. Integrated Control Strategy: Biological controls are being tested. Wick wipe with herbicide (Group I), before flowering. Cultivate before seeding, as most varieties are annuals. This is a declared “Noxious Weed” in Victoria, Tasmania, Western Australia and Queensland. Comments: These plants are generally avoided, but hungry stock, or stock new to an area may eat them. They may turn up as contaminants in hay, or their toxic seeds may contaminate feed grain. An erect, annual forb with pale green stems and spreading branches, growing over a metre 30 high. The leaves are ovate, green or purple, with serrated edges. The flowers are trumpetshaped, usually white or purple, on a short stalk and appear late in spring and early summer. In autumn the prickly seed capsule dries off and spreads seeds, which can remain dormant for up to 20 years. A serious weed in summer crops and pastures, depriving other plants of moisture, nutrients and light. The plant has a strong bitter taste and an offensive odour, which deters grazing animals. Humans can also be affected, and may develop dermatitis from the leaves, flowers and fruits. No 236 Datura spp UNIVERSITY OF ILLINOIS
