US 6,444,614 B2 · Aspartic acid derivative-containing compositions and use thereof in stimulating and/or regulating plant and plant precursor growth

Abstract

Described is the use, [in the absence of (a) fertilizers and (b) Periodic Table Group IIa and greater Group metal cations and chelated metals], of aqueous solutions of the N-substituted aspartic acids, (i) N-(1,2-dicarboxyethyl)aspartic acid [‘IDS’] and (ii) N,N′-1,2-ethanediylbis-aspartic acid [‘EDDS’], ammonium salts, alkali metal salts, ammonium-alkali metal salts and optical isomers thereof in stimulating or regulating the growth of a living, growing plant precursor [germinating seed] or plant [from the ‘seedling stage’ to the ‘late-maturity stage’]. Such use, optionally, is in the presence of aditional adjuvants free from fertilizer as well as Periodic Table Group IIa and greater metal Group cations and chelated metals. Also described are novel compositions comprising (a) the ‘IDS’ and/or ammonium, alkali metal, ammonium-alkali metal salts thereof as well as optical isomers thereof in admixture with (b) the ‘EDDS’ and/or ammonium, alkali metal and ammonium-alkali metal salts thereof as well as optical isomers thereof.

A fertilizer-free and Group IIa or higher Group metal cation-free composition of matter consisting essentially of water and a plant precursor or plant growth stimulating or regulating concentration of a mixture of (a) IDS and/or one or more of its ammonium salts, alkali metal salts, ammonium-alkali metal salts or optical isomers thereof;

(b) EDDS and/or one or more of its ammonium salts, alkali metal salts, ammonium-alkali metal salts or optical isomers thereof ;
and, optionally, 1 H-indole-3-butanoic acid, with the weight ratio of (a):(b) being from about 1:20 up to about 20:1.

A process for stimulating or regulating, substantially in the absence of any fertilizer or any Periodic Table Group IIa or higher Group cations or chelated metals, the growth of a living, growing plant precursor which is-a germinating seed, or plant having a degree of maturity of from about >0% of full growth, the seedling stage, up to about <100% of full growth, the late maturity stage, consisting of the steps of:

(a) formulating an aqueous plant precursor or plant growth-regulating or stimulating solution consisting essentially of water, substantially free of any (i) fertilizer and (ii) Periodic Table Group IIa or higher Group metal cations or chelated metals;
at least one substantially pure nitrogen-containing compound selected from the group consisting of IDS, EDDS, ammonium salts thereof, alkali metal salts thereof, ammonium-alkali metal salts thereof and optical isomers thereof;
and, optionally, 1H-indole-3-butanoic acid;
(b) providing a living, growing (i) plant precursor, or (ii) plant having a degree of maturity from about >0% up to about <100% of full growth;
and
(c) applying, in the absence of any fertilizer or any Periodic Table Group IIa or higher Group metal cations or chelated metals, a plant precursor or plant growth stimulating or regulating concentration and quantity of said aqueous plant precursor or plant growth-regulating or stimulating solution to said plant precursor or to said plant or to the effective proximity of said plant precursor or said plant, over a period of time and at a rate such that the plant precursor growth or the plant growth is stimulated or regulated.
