Delachlor
Weed control herbicide
Delachlor is a chloroacetanilide herbicide, used on grasses, rice and sugarbeet. It was first reported in 1967 and introduced by Monsanto, though by 1974 commercial factors had halted its commercialisation, so delachlor is now considered obsolete, and appears never to have been registered in the USA.
Delachlor's HRAC group is Group K (Australia), Group K3 (Global) and Group 15 (numeric).
01Effectiveness
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.
Delachlor appears to be used in China, where it has reportedly good control of goosegrass.
02Safety
The LD50 (by mouth) is reported to be 1775 mg/kg on an SDS, but 733 mg/kg on PPDB. The difference is similar to the difference between paracetamol and methanol.
03Chemistry
It is soluble in chloroform and somewhat soluble in ethyl acetate.
