Abstract

Fenoxaprop-ethyl is a selective aryloxyphenoxypropionate herbicide used widely to control annual and perennial grasses. A monoclonal antibody (MAb) against fenoxaprop-ethyl (FE), designated as 3E6B9C, was produced and had very low cross-reactivity with some of its structural analogs, such as clodinafop-propargyl, diclofop-methyl, lactofen, and quizalofop-p-ethyl. An indirect competitive enzyme-linked immunosorbent assay (icELISA) was developed. The concentration of R-(+)-fenoxaprop-ethyl (R-FE) producing 50% of inhibition (IC(50)) and the working range of icELISA were 3.1 ng/mL and 0.6-29 ng/mL, respectively. This assay is also sensitive to R-fenoxaprop, S-(-)-fenoxaprop-ethyl, and metamifop with IC(50) of 3.4, 2.7, and 3.5 ng/mL, respectively. The recoveries of R-FE in soil samples with the icELISA were 86-102%.
