Abstract
The present invention is directed to liquid homogenous adjuvant blends that include a liquid iminodipropionate amphoteric surfactant, ammonium sulfate and water. The liquid homogenous adjuvant blends are used in spray carrier containing herbicides for conytrol of weeds or other undesired vegetation.
Claims11
A liquid homogeneous adjuvant blend comprising:
- from about 10 to about 25 weight to volume percent of a liquid iminodipropionate amphoteric surfactant selected from the group consisting of C12-15 alkyloxypropyl-3-iminodipropionic acid, mono(sodium or potassium or ammonium) salt, decyloxypropyl-3-iminodipropionic acid, mono(sodium or potassium, or ammonium) salt {alternate name:
- beta.-alanine,N-(2-carboxyethyl)-N-[3-(decyloxy)propyl], mono(sodium or potassium or ammonium) salt}, and mixtures thereof;
- ammonium sulfate;
- and
- water.
A herbicidal aqueous spray composition comprising:
- a liquid iminodipropionate amphoteric surfactant selected from the group consisting of C12-15 alkyloxypropyl-3-iminodipropionic acid, mono(sodium or potassium or ammonium) salt, decyloxypropyl-3-iminodipropionic acid, mono (sodium or potassium, or ammonium) salt {alternate name:
- beta.-alanine,N-(2-carboxyethyl)-N-[3-(decyloxy)propyl], mono(sodium or potassium or ammonium) salt}, and mixtures thereof;
- an effective amount of herbicide;
- ammonium sulfate;
- and
- water.
A method of controlling weeds which comprises applying a postemergence herbicidal spray composition to weeds and/or other undesired vegetation, the final herbicidal spray composition comprising:
- a liquid iminodipropionate amphoteric surfactant selected from the group consisting of C12-15 alkyloxypropyl-3-iminodipropionic acid, mono(sodium or potassium or ammonium) salt, decyloxypropyl-3-iminodipropionic acid, mono(sodium or potassium, or ammonium) salt {alternate name:
- beta.-alanine, N-(2-carboxyethyl)-N-[3-(decyloxy)propyl], mono(sodium or potassium or ammonium) salt}, and mixtures thereof;
- ammonium sulfate;
- and
- water;
- an effective amount of glyphosate;
- and
- additional water to make up the final spray solution.
A herbicidal aqueous spray composition comprising:
- from about 0.05 to about 0.5 weight percent, based on the weight of the spray composition, of a liquid iminodipropionate amphoteric surfactant selected from the group consisting of C12-15 alkyloxypropyl-3-iminodipropionic acid, mono(sodium or potassium or ammonium) salt, decyloxypropyl-3-iminodipropionic acid, mono(sodium or potassium, or ammonium) salt {alternate name:
- beta.-alanine,N-(2-carboxyethyl)-N-[3-(decyloxy)propyl], mono(sodium or potassium or ammonium) salt}, and mixtures thereof;
- from about 0.001 to about 4 weight percent, based on the weight of the spray composition of a herbicide selected from the group consisting of glyphosate, weak acid herbicides, and mixtures thereof;
- from about 0.3 to about 1 weight percent, based on the weight of the spray composition, ammonium sulfate;
- and
- water.
