This invention provides synergistic herbicidal compositions of glycolate and lactate esters of phenoxybenzoic acids with cyclohexonediones. These compositions are relatively safe to soybeans and have unexpected herbicidal effectiveness against broadleaf weeds such as velvetleaf.

Abstract:
Combinations of a 2-nitro-5 (Substituted phenoxy) benzoic acid or derivative thereof, e. g. sodium acifluorfen with a derivative of 3,5-dihalo-4-hydroxybenzonitrile e. g. 3,5-dibromo-4-hydroxy-benzonitrile (bromoxynil, especially in a salt form), exhibit unexpected synergistic herbicidal activity against several important weed species when applied post-emergence in important agronomic crops.

Abstract:
A series of ester and salt derivatives of fluorene-9-carboxylic acid and fluorene-1-carboxylic acid exhibit significant plant growth regulating properties, useful in controlling the size, shape, dormancy time, flowering time and/or fruit setting of plants, depending upon the concentrations used. They may also be used to control the growth rate, texture and color of turf grass. Presently preferred compounds include the cis-2,5-dimethylpyrrolidine salt of 1-fluorenecarboxylic acid, 9-cis-2,5-dimethyl-1-pyrrolidinyl-2-chlorofluorene-9-carboxylic acid, methyl ester, the 2,6-dimethylpiperidine salt of 1-fluorenecarboxylic acid, and the cis-2,5-dimethylpyrrolidine salt of 9-hydroxyfluorene-9-carboxylic acid.
