Abstract
N-Acyl sarcosinates, when combined at relatively low concentrations with 2-amino-4-(hydroxymethyl phosphinyl) butanoic herbicide (glufosinate) as an adjuvant, provide for beneficial herbicide formulations exhibiting excellent activity, little or no phytotoxicity (including aquatic toxicity), and low irritancy (including ocular irritancy).
Claims19
A herbicidal composition comprising a herbicidally effective amount of 2-amino-4-(hydroxymethyl phosphinyl) butanoic acid or a salt thereof, and between about 4 parts and about 40 parts, per 100 parts of said butanoic acid or said salt thereof, of an adjuvant comprising an N-acyl sarcosinate or a salt thereof having the formula:
- RCON(CH3)CH2COOX
- wherein R is C8 to C22 alkyl or alkenyl, and X is hydrogen, alkali metal, ammonium, C1-C6 alkylamine or an amino alcohol.
A herbicidal composition comprising a herbicidally effective amount of 2-amino-4-(hydroxymethyl phosphinyl) butanoic acid or a salt thereof, and between about 4 parts and about 16 parts, per 100 parts of said butanoic acid or said salt thereof, of diethylamine sacosinate.
A method of controlling weeds in crop, comprising applying to said crop or the locus thereof an effective amount of a herbicidal composition comprising 2-amino-4-(hydroxymethyl phosphinyl) butanoic acid or a salt thereof and between about 4 parts and about 40 parts, per 100 parts of said butanoic acid or said salt thereof, of an adjuvant comprising an N-acyl sarcosinate or a salt thereof having the formula:
- RCON(CH3)CH2COOX
- wherein R is C8 to C22 alkyl or alkenyl, and X is hydrogen, alkali metal, ammonium, C1-C6 alkylamine or an amino alcohol.
A herbicidal composition comprising a herbicidally effective amount of 2-amino-4-(hydroxymethyl phosphinyl) butanoic acid or a salt thereof, and between about 4 parts and about 16 parts, per 100 parts of said butanoic acid or said salt thereof, of ammonium sacosinate.
