Terpenylaminoalkanol fish toxicants

Claim 2

A process for controlling fish populations which comprises treating the water wherein said fish reside with a piscicidally effective amount of an aminoalkanol toxicant or water-soluble salt thereof, having the formula: ##STR2## wherein: T is a radical selected from the group consisting of geranyl, citronellyl, bupleuryl, neryl, lavandulyl, linalyl, myrcenyl, isobornyl and tetrahydrogeranyl; R is independently hydrogen or lower alkyl radical containing one to four carbon atoms; and X is an integer of 1 to 4.

Claim 3

The process according to claim 1 wherein said toxicant is applied at an effective rate of from about 0.03 to 10 parts active toxicant per million parts of water treated.

Claim 4

The process according to claim 1 wherein said water-soluble salt is selected from the group consisting of inorganic acid salts, organic acid salts, and quaternary ammonium salts of said amino-alkanol toxicant.

Claim 5

The process of claim 1 wherein the toxicant is applied to the water as a hydrochloride salt.

Claim 6

The process of claim 1 wherein the toxicant is N-(2-hydroxyethyl) digeranylamine.

Claim 7

The process of claim 5 wherein a 50% aqueous solution of N-(2-hydroxyethyl) digeranylamine hydrochloride is applied at an effective rate of from 0.03 to 10 parts active toxicant per million parts of water treated.

Claim 8

The process of claim 1 wherein T is 3,7-dimethyloctyl.

Claim 9

The process of claim 1 wherein the toxicant is N-(2-hydroxyethyl) di(3,7-dimethyloctyl) amine.

Claim 10

The process of claim 1 wherein T is isobornyl.

Claim 11

The process of claim 1 wherein the toxicant is the hydrochloride of N-(2-hydroxyethyl) diisobornylamine.

Claim 12

The process of claim 1 wherein the controlled species is common carp (Cyprinus carpio).

Claim 13

The process of claim 1 wherein the controlled species is white sucker (Catostomus commersoni).

Claim 14

The process of claim 1 where T is geranyl.

Claim 15

A process for selectively controlling undesirable species of fish, especially carp or white sucker species, in a water environment where other desirable species of fish are present, which comprises treating the water wherein said fish reside with a piscicidally effective amount of N-(2-hydroxyethyl) digeranylamine.

Claim 16

A process for selectively controlling undesirable species of fish, especially carp or white sucker species, in a water environment where other desirable species of fish are present, which comprises treating the water wherein said fish reside with a piscicidally effective amount of N-(2-hydroxyethyl) digeranylamine.

Claim 17

The process of claim 14 wherein the water is treated with 0.05 to 0.13 parts N-(2-hydroxyethyl) digeranylamine per million parts of water.

Claim 18

A process for selectively controlling undesirable species of fish, especially carp or white sucker species, in a water environment where other desirable species of fish are present which comprises treating the water wherein said fish reside with a piscicidally effective amount of an aminoalkanol toxicant having the formula: ##STR3## wherein: T is a radical selected from the group consisting of geranyl, citronellyl, bupleuryl, neryl, lavandulyl, linalyl, myrcenyl, isobornyl and tetrahydrogeranyl; R is independently hydrogen or lower alkyl radical containing one to four carbon atoms; and X is an integer of 1 to 4.

Claim 19

A process for selectively controlling undesirable species of fish, especially carp or white sucker species, in a water environment where other desirable species of fish are present which comprises treating the water wherein said fish reside with a piscicidally effective amount of an aminoalkanol toxicant having the formula: ##STR3## wherein: T is a radical selected from the group consisting of geranyl, citronellyl, bupleuryl, neryl, lavandulyl, linalyl, myrcenyl, isobornyl and tetrahydrogeranyl; R is independently hydrogen or lower alkyl radical containing one to four carbon atoms; and X is an integer of 1 to 4.
