Abstract
Abstract Process of employing as herbicides N-phenylalkyl - γ hydroxybutyramide or methyl or halo derivatives thereof wherein the methyl or halo substituent occupies any one of two of the ortho-, meta- and para-positions of the phenyl ring; said compounds having the following formula: ##SPC1## Wherein m is 1 or 0 and R 1 is hydrogen, methyl, chlorine, or bromine; R 2 is hydrogen, methyl or, when R 1 is other than hydrogen, R 2 can also be chlorine or bromine; and R 3 is hydrogen or, when R 1 is hydrogen, R 3 can also be chlorine or bromine. The above compounds are useful as plant growth regulating agents particularly as a herbicide or control agents for aquatic weeds.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
76 words
The method of controlling the growth of aquatic weeds which comprises applying to the site where said growth is to be controlled, an effective amount of an herbicidal composition comprising as the active component, an N-phenylakyl-2-hydroxybutyramide having the following formula: ##SPC3## wherein m is 1 or 0; at least one of R 1 and R 3 is hydrogen and the other is hydrogen, methyl, chlorine or bromine, and R 2 is hydrogen, methyl, chlorine or bromine.
Claim 2
Independent Claim
76 words
The method of controlling the growth of aquatic weeds which comprises applying to the site where said growth is to be controlled, an effective amount of an herbicidal composition comprising as the active component, an N-phenylakyl-2-hydroxybutyramide having the following formula: ##SPC3## wherein m is 1 or 0; at least one of R 1 and R 3 is hydrogen and the other is hydrogen, methyl, chlorine or bromine, and R 2 is hydrogen, methyl, chlorine or bromine.
Claim 3
Dependent Claim
17 words
The process of claim 1 wherein the benzylhydroxybutyramide is unsubstituted or is substituted in the para position.
Claim 4
Dependent Claim
35 words
The process of claim 1 wherein an inert carrier is employed with the benzylhydroxybutyramide and the concentration of the benzylhydroxybutyramide is between about 0.05 and about 25% by volume with respect to the inert carrier.
Claim 5
Dependent Claim
28 words

Claim 6
Dependent Claim
34 words
The process of claim 3 wherein the carrier is selected from the group comprising diatomaceous earth, talc, vermiculite, kaolin, pumice, bentonite, fuller's earth, asbestos, chalk, cross-linked polyvinylpyrrolidone, alcohol, kerosine, acetone, dimethyl sulfoxide and water.
Claim 7
Dependent Claim
16 words
The process of claim 4 wherein the composition contains a non-ionic surfactant as a wetting agent.
Claim 8
Dependent Claim
11 words
The process of claim 4 wherein the composition contains a binder.
Claim 9
Dependent Claim
12 words
The process of claim 4 wherein the composition contains a gelling agent.
Claim 10
Dependent Claim
21 words
The method of claim 1 wherein 1 to 50 parts per million of the benzylhydroxybutyramide is applied to the plant situs.
