Rayless goldenrod (RG; Isocoma pluriflora) poisons livestock in the southwestern U.S., west Texas, and northern Mexico. The putative toxin(s) have historically been thought to be benzofuran ketones. Goats have been used successfully as a model of RG poisoning. The transmammary transfer of toxicity
Rayless goldenrod (Isocoma pluriflora) has been known to be toxic to livestock in the southwestern United States for many years; however, chemical composition of the plant as well as the dosage and duration required to cause toxicosis have not been completely described. Tremetol, the historical
Isocoma pluriflora and Isocoma acradenia are toxic plants that contain the putative toxin tremetone. It is common for I. pluriflora to poison livestock in the southwestern United States. I. acradenia has been suspected of poisoning livestock but its toxicity has not been
Rayless goldenrod (Isocoma pluriflora) sporadically poisons livestock in the southwestern United States. Similarities with white snakeroot (Ageratina altissima) poisoning and nearly identical chemical analyses led early researchers to conclude that tremetol, a mixture of benzofuran ketones, is the
Rayless goldenrod (Isocoma pluriflora) sporadically poisons horses and other livestock in the southwestern United States. Similar to livestock poisoning by white snakeroot (Ageratina altissima) in the midwestern United States, previous research suggests that benzofuran ketones (BFK: tremetone,
