The absorption, translocation, and metabolism of difenopenten-ethyl in soybean and wheat

Add time:08/06/2019    Source:sciencedirect.com

The postemergence graminicide, difenopenten-ethyl [ethyl 4-(4-(4′-trifluoromethylphenoxy)-phenoxy)-2-pentenoate], was rapidly hydrolyzed to its acid, difenopenten, in both susceptible wheat and resistant soybean followed by hydroxylation of the pentenoic acid side chain to a 3-hydroxy metabolite and subsequent conjugation to water-soluble polar metabolite(s). Metabolism of the herbicide did not differ greatly between the two species. A minor decarboxylation product of the 3-hydroxy metabolite, isolated from soybean cell suspension culture, was identified as a substituted 2-butanone metabolite. Difenopenten-ethyl is rapidly absorbed by both species through the roots and leaf surfaces but apoplastic and symplastic translocation is very limited. Differential absorption, translocation, and metabolism may not be major factors in the selective action of difenopenten-ethyl.
