Abstract
A herbicide composition which comprises a herbicide and a small but herbicide absorption enhancing effective amount of a water soluble, non-aromatic polyorganic acid or a salt or copolymer thereof such as polyaspartic acid.
Claims22
A herbicide composition which comprises:
- a herbicide, and
- a small but herbicide absorption enhancing effective amount of water soluble polyaspartic acid, and its salts or copolymers.
A herbicide solution composition which comprises:
- a herbicide solution, and
- a small but herbicide absorption enhancing effective amount of a water soluble, non-aromatic, polyorganic acid or salt thereof which is a polyamino acid or a copolymer of said acid, or salt thereof with the acid being polyaspartic acid, said polyaspartic acid having a molecular weight larger than 1500.
A method of enhancing the absorption effectiveness of herbicides, said method comprising:
- adding to a herbicide a small but herbicide absorption enhancing effective amount of a water soluble, non-aromatic polyorganic acid or salt form thereof which is a polyamino acid or a copolymer of said acid, or salt thereof, selected from the group consisting of polyaspartic acid, polyglutamic acid, polyglycine, polylysine, a copolymer of cysteine and glutamic acid and a terpolymer of cysteine, glutamic acid and aspartic acid, and salt form thereof said polyamino acid having a molecular weight larger than 1500.
