Abstract

The present invention is directed to a water-soluble granule compositions comprising 1-amino-1-cyclopropanecarboxylic acid (“ACC”), a filler selected from the group consisting of lactose, dextrose, sucrose or a mixture thereof, one or more wetting agents selected from the group consisting of a non-ionic ethoxylated sorbitan, a polyoxyethylene glycol alkyl ether and an anionic dioctyl sulfosuccinate, one or more binders selected from the group consisting of polyvinylpyrrolidone and a lignosulfonate and one or more organosilicon surfactants selected from the group consisting of a polyalkyleneoxide modified heptamethyltrisiloxane and a polyether trisiloxane.

First claim

What is claimed is:

1. A stable water-soluble granule composition consisting of:
from about 20% to about 40% w/w 1-amino-1-cyclopropanecarboxylic acid;
from about 37% to about 77% w/w lactose monohydrate;
from about 1.5% to about 3.5% w/w of one or more wetting agents are selected from the group consisting of polyoxyethylene vegetable-based fatty ether derived from cetyl alcohol, polysorbate 20 and dioctyl sulfosuccinate sodium salt;
from about 0.5% to about 2.0% w/w of one or more binders selected from the group consisting of polyvinylpyrrolidone and sodium lignosulfonate;
from about 0.05% to about 0.2% w/w one or more organosilicon surfactants selected from the group consisting of a polyalkyleneoxide modified heptamethyltrisiloxane and a polyether trisiloxane;
from about 2% to about 4% w/w water; and
optionally, from about 5% to about 20% w/w calcium chloride, wherein the composition has a pH from about 4 to about 6 and wherein w/w denotes weight by total weight of the composition.

2. A method of reducing crop load of woody perennials comprising applying a composition of claim 1 to a plant.

3. The method of claim 2 , wherein the plant is a stone fruit tree or an apple tree.

4. A method of enhancing grape coloration comprising applying a composition of claim 1 to a grape plant.
