Abstract: Various chemicals were applied to whole-tree, quarter-tree, or single-limb units to determine their efficacy for delaying apple ( Malus domestica Borkh.) fruit abscission. NAA and the herbicides fenoprop, dicamba, triclopyr, lontrel, fluroxypyr, and chloroxuron delayed fruit abscission. Benzoic acid, calcium acetate; the growth regulators lactidichlor ethyl, mefluidide, BA, GA 4+7 , and chlormequat; and the herbicides pronamide, pendimethalin, chloramben, and DCPA did not delay fruit abscission. Chemical names used: benzoic acid,3,6-dichloro-2-methoxy,2-ethoxy, 1-methyl,2-oxoethylester (lactidichlor ethyl); 1-naphthaleneacetic acid (NAA); N -(phenylmethyl)-1 H -purin-6-amine (BA); gibberellin (GA 4+7 ); N -[2,4-dimethyl-5-[[(trifluoromethyl)sulfonyl]amino] phenyl]acetamide (mefluidide); 3,5-dichloro( N -1,1-dimethyl-2-propynyl)benzamide (pronamide); N -(1-ethylpropyl)-3,4-dimethyl-2,6-dinitrobenzenamine (pendimethalin); 3,6-dichloropicolinic acid (lontrel); 3-amino-2,5-dichlorobenzoic acid (chloramben); 2-chloro- N,N,N -trimethylethanaminium chloride (chlormequat); 4-amino-3,5-dichloro-6-fluoro-2-pyridinyl oxyacetic acid (fluroxypyr); butanedioic acid mono 2,2-dimethylhydrazide)4-chlorophenyl)methyl]-(1,1-dimethylethyl)-1- H -1,2,4,triazol-1-ethanol (paclobutrazol); N' -[4-(4-chlorophenoxy)phenyl]- N,N -dimethylurea (chloroxuron); dimethyl tetrachloroterephthalate (DCPA); 3,6-dichloro-2-methoxybenzoic acid (dicamba); 2-(2,4,5-trichlorophenoxy) propanoic acid (fenoprop).
