[The residue and degradation of herbicide ammonium 2,4-dichloro-6-nitrophenate in the system of wheat and soil].
To study the residue and degradation of ammonium 2, 4-dichloro-6-nitrophenate (a herbicide) in wheat and soil, a field test was made in Wuxi Jiangsu of East China and Chengdu Sichuan of West Chain during 1985-1992. The results showed that ammonium 2,4-dichloro-6-nitrophenate was unstable with a half-life of 12-18 days in soil. The residue in wheat was less than 0.05 mg/kg on the field doses recommended. These results may be used as a basis for the hygienic evaluation of ammonium, 2,4-dichloro-6-nitrophenate.
