Chemistry:Delachlor
Delachlor is a chloroacetanilide herbicide, used on grasses, rice and sugarbeet.[1][2] It was first reported in 1967 and introduced by Monsanto,[3] though by 1974 commercial factors had halted its commercialisation,[4] so delachlor is now considered obsolete,[5] and appears never to have been registered in the USA.[6]
In artificial soil tests of phytotoxicity, with the herbicides cycloate, benzthiazuron and pyrazon. Delachlor was the most active in organic soils (>11% organics) though cycloate was more potent in other soils.[7]
The LD50 (by mouth) is reported to be 1775 mg/kg on an SDS,[8] but 733 mg/kg on PPDB.[5] The difference is similar to the difference between paracetamol and methanol.
It is soluble in chloroform and somewhat soluble in ethyl acetate.[8]
