Abstract
The present invention is directed to the treatment of apple trees, peach trees, and grape vines with 3′-methyl-(S)-abscisic acid, 3′-propargyl-(S)-abscisic acid, and/or salts thereof in order to reduce the number of fruits on the trees or vines that grow to maturity.
Claims14
A method of thinning an apple tree comprising applying from about 100 to about 300 parts per million of an abscisic acid derivative selected from the group consisting of (2Z,4E)-5-((S)-1-hydroxy-2,3,6,6-tetramethyl-4-oxocyclohex-2-en-1-yl)-3-methylpenta-2,4-dienoic acid (3′-methyl-(S)-abscisic acid), (2Z,4E)-5-((S)-1-hydroxy-2,6,6-trimethyl-4-oxo-3-(prop-2-yn-1-yl)cyclohex-2-en-1-yl)-3-methylpenta-2,4-dienoic acid (3′-propargyl-(S)-abscisic acid), and a salt thereof to the apple tree.
A method of thinning a peach tree comprising applying from about 100 to about 300 parts per million of (2Z,4E)-5-((S)-1-hydroxy-2,3,6,6-tetramethyl-4-oxocyclohex-2-en-1-yl)-3-methylpenta-2,4-dienoic acid (3′-methyl-(S)-abscisic acid) or a salt thereof to the peach tree.
