Abstract

In soil enrichment studies, the microbial degradation of 2,2-dichloropropionic acid (dalapon) was inhibited in the presence of 3-amino-1,2,4-triazole (amitrole), but dalapon had little or no effect on behavior of amitrole. Phytotoxic residues of the herbicides persisted longer in soils when the herbicides were applied in combination than when each was used individually. Although amitrole disappeared rapidly from all amitrole-treated soils, dalapon, when applied in combination with amitrole, disappeared more slowly than when used alone. Dalapon did not affect the behavior of amitrole in muck soil, but affected the availability of amitrole in Hagerstown silty clay loam treated with high rates of amitrole.
