Abstract

The present invention relates to exogenous compositions and methods of their use, wherein the exogenous chemicals are applied to one or more surface layers of plants to generate a herbicidal biological response and in particular to a glyphosate-based herbicidal composition for spray application to a plant having superior properties of herbicidal cuticle layer coating and penetration, herbicidal uptake, and herbicidal translocation, without cuticle layer damage.

Claims

1. A composition for treating a plant comprising

(a) an exogenous chemical;

(b) a first adjuvant;

(b) a second adjuvant; and

(c) an aqueous-based diluent,

wherein the exogenous chemical is from about 35% to about 45% by weight glyphosate isopropylamine salt;

the first adjuvant comprises at least two fatty acids, at least two fatty-acid esters, hydroacrylic acid, a phospholipid, a phospholipid derivative, a glycol, and a polyoxyethylene; and

the second adjuvant comprises an amine ethoxylate, further wherein the at least two fatty acids and at least two fatty-acid esters have a saturated alkyl or acyl chain from about 8 carbon atoms to about 22 carbon atoms.

2. The composition of claim 1 comprising from about 35% to about 45% by weight of the aqueous-based diluent;

and from about 10% to about 20% by weight of the first and second adjuvants combined.

3. The composition of claim 1 which provides substantial uptake, translocation, and efficacy of the exogenous chemical, and insubstantial damage to a cuticle layer of the plant treated with the composition.

4. A method of spraying a composition comprising

(a) an exogenous chemical;

(b) a first adjuvant;

(b) a second adjuvant; and

(c) an aqueous-based diluent,

wherein the exogenous chemical is from about 35% to about 45% by weight glyphosate isopropylamine salt the first adjuvant comprises at least two fatty acids, at least two fatty-acid esters, hydroacrylic acid, a phospholipid, a phospholipid derivative, a glycol, and a polyoxyethylene; and

the second adjuvant comprises an amine ethoxylate, further wherein the at least two fatty acids and at least two fatty-acid esters have a saturated alkyl or acyl chain from about 8 carbon atoms to about 22 carbon atoms, the method of spraying comprising the steps of

(a) providing a pressure-based spraying apparatus comprising a container that holds the composition to be sprayed and an orientable spray nozzle in fluid communication with the composition in the container that provides a flow rate and a spray angle of the composition to be sprayed and a dispersion of suitable, sprayed-droplet sizes;

(b) placing an amount of the composition into the container;

(c) providing pressure to the composition to be sprayed; and

(d) producing a sprayed dispersion of suitable droplet sizes of the composition.

5. The method of claim 4 wherein the produced spray dispersion contacts foliage of a targeted plant.
