Extract

In contrast to the great development of chlorophenoxyacetic acids as herbicides, the fluorophenoxyacetic acids have received very little attention in weed control work, chiefly because they were difficult to synthesize. In addition until recently, they were not widely available. Thompson et al. (5) listed 2–fluorophenoxyacetic and 2–methyl–4–fluorophenoxyacetic acids as plant growth inhibitors. Crane and Blondeau (1) reported 4–fluorophenoxyacetic acid to be as effective as 4–chlorophenoxyacetic acid for inducing parthenocarpy in figs. A 100 ppm spray gave 88% fruit set with no foliar damage. Edgerton and Hoffman (2) stated that the same compound was moderately effective in delaying leaf abscission on apple trees and produced a 2,4–D-type formative effect on treated shoots. Weintraub et al. (6) showed with a bean leaf-area repression test that some of the fluorophenoxyacetic acids have a very high formative activity comparable to that of the most active chlorophenoxyacetic acids.
