Tricamba

Tricamba is an obsolete benzoic acid herbicide once used to control annual and perennial weeds, similar to dicamba. It is selective, systemic, and absorbed through leaves.^[2] It was introduced in the early 1960s.^[1]

Chemical properties

Tricamba is achiral,^[3] and while only slightly soluble in water, is soluble in most organic solvents, and forms water-soluble alkali metal salts. It is stable to oxidation and hydrolisis under conventional conditions.^[1]

Safety

Tricamba is of low toxicity to mammals and birds. Its LD₅₀ ranges from 283 to 951 mg/kg depending on species. It is of low dietary toxicity, and is unlikely to be hazardous in normal agricultural usage. Tricamba is significantly more toxic than dicamba.^[1]
