Herbicidal and algaestatic and algaecidal compositions and use thereof comprising copper salts; both soluble acid salts as copper sulfate, chloride, nitrate, acetate, sulfamate, gluconate, citrate, etc. and basic copper salts such as basic copper sulfate, cupric hydroxide, basic copper carbonate, basic copper chloride and the like for a method for treating bodies of water to arrest or eliminate the growth of algae and aquatic weeds by giving a more efficient algaestat, algaecide and/or herbicide, when the copper salts or insoluble basic copper salts are used as a complex with an alkylene diamine, such as ethylenediamine, propylenediamine and substituted derivatives of these; or poly (aminoalkylene)n-NH2 wherein n is from 2 to 4, 5 or 6 such as diethylene triamine, triethylene tetraamine, tetraethylene pentaamine, dipropylene triamine, or mixtures of each of these with the others, including diamines, such as aminoethyl ethanolamine and mixtures of same with the other amines; in the complex a high copper content in useful form is achieved and the effect of the complex on the weeds is prolonged and noteworthy; as against previous copper compounds which require the use of an organic herbicide such as 1,1′ethylene-2,2′dipyridinium dibromide, (DIQUATR) with the copper compound to produce satisfactory herbicidal action at safe and economic copper levels, the herein disclosed and claimed copper and alkylene diamine complex is used alone for aquatic weed control.

A method for combatting aquatic weeds growing in waters, comprising dispersing in said waters an aqueous solution of a water soluble complex of a divalent copper salt and an amine of the formula: R-RN-ALK-NRR wherein ALK is alkylene of 2 or 3 carbon atoms and each R is independently hydrogen, methyl
A method for combatting aquatic weeds growing in waters, comprising dispersing in said waters an aqueous solution of a water soluble complex of a divalent copper salt and an amine of the formula: R-RN-ALK-NRR wherein ALK is alkylene of 2 or 3 carbon atoms and each R is independently hydrogen, methyl or ethyl, the amine to copper mol ratio being from 1:1 to 10:1, in an amount sufficient to provide on the basis of said waters a copper concentration of from 0.1 to 10.0 ppm, and thereby contacting said weeds with a herbicidally effective amount of said complex.
