Agricultural adjuvant compositions, pesticide compositions, and methods for using such compositions

1. A pesticide composition, comprising, based on 100 parts by weight of the composition:

(a) from greater than 0 to about 20 parts by weight of a combined amount of one or more betaine surfactants, and one or more glycoside surfactants, comprising, based on 100 parts by weight of the combined amount:

(i) from about 50 to less than 100 parts by weight of the one or more betaine surfactants,

said betaine surfactant comprising one or more compounds according to formula (I):

wherein:

R is methylene or dimethylene,

R 1 and R 2 are each independently alkyl, alkenyl, alkoxyalkyl, hydroxyalkyl, hydroxy-terminated poly(oxyalkylene), or alkoxy-terminated poly(oxyalkylene), and

R 3 is a (C 6 -C 30 )alkyl,

and

(ii) from greater than 0 to about 50 parts by weight of one or more glycoside surfactants,

said glycoside surfactant comprising one or more compounds according to formula (II):

R 4 O(R 5 ) m R 6   (II)

wherein:

R 4 is a (C 8 -C 22 )alkyl,

each R 5 is independently a divalent monosaccharide radical,

R 6 is a monovalent monosaccharide radical, and

m is an integer of from 0 to about 10,

(b) water, and

(c) one or more pesticides selected from glyphosate, glufosinate, dicamba, 2,4-D, their respective water soluble salts and esters, and mixtures thereof.

2. The composition of claim 1 , wherein the combined amount of the one or more betaine surfactants and one or more glycoside surfactants, comprises, based on 100 parts by weight of the combined amount:

(i) from about 75 to less than 100 parts by weight of the one or more betaine surfactants, and

(i) from greater than 0 to about 25 parts by weight, of the one or more glycoside surfactants.

3. The composition of claim 1 , wherein:

the betaine surfactant comprises one or more compounds according to formula (I):

wherein:

R is methylene,

R 1 and R 2 are each independently (C 1 -C 6 )alkyl, and

R 3 is (C 6 -C 30 )alkyl, and

the glycoside surfactant comprises one or more compounds according to formula (II):

wherein:

R 4 is (C 8 -C 22 )alkyl,

each R 5 and R 6 is a glucose residue, and

m is an integer of from 0 to 5.

4. The composition of claim 1 , wherein the pesticide comprises a glyphosate herbicide selected from potassium salt of glyphosate, the sodium salt of glyphosate, the isopropyl amine salt of glyphosate, the ammonium salt of glyphosate, and mixtures thereof.

5. A pesticide composition, comprising, based on 100 parts by weight of the composition:

(a) from greater than 0 to about 20 parts by weight of a combined amount of one or more betaine surfactants, and one or more glycoside surfactants, comprising, based on 100 parts by weight of the combined amount:

(i) from about 75 to less than 100 parts by weight parts by weight of (C 12 -C 14 )alkyl dimethylbetaine surfactants, and

(ii) from greater than 0 to about 25 parts by weight of (C 8 -C 10 )alkyl polyglucoside surfactants,

(b) water, and

(c) one or more pesticides, comprising the isopropyl amine salt of glyphosate.
