INCORPORATION OF SEQUENCE LISTING

A paper copy of the Sequence Listing and a computer readable form of the sequence containing the file named 40—21—59223_PCT, which is 21 kilobytes in size (as measured in Microsoft Windows Explorer), are provided herein and are herein incorporated by reference. This Sequence Listing consists of SEQ ID NOS: 1 to 42.

FIELD OF THE INVENTION

- Top of Page


The present disclosure relates generally to synergistic combinations of herbicides and methods of using such synergistic combinations of herbicides to control the growth of one or more plant species in an agricultural or non-agricultural land area.

BACKGROUND

- Top of Page


OF THE INVENTION

Three classes of herbicides commonly used to control unwanted plant growth on agricultural and non-agricultural lands are auxin herbicides (such as dicamba), photosystem II inhibitor herbicides (such as metribuzin), and chloroacetanilide herbicides (such as acetochlor). Although each class can provide effective herbicidal control against various plant species, additional enhancement of performance is still desirable. Such enhancement of performance can include, for example, further increasing the herbicidal effectiveness, decreasing the required application rate, and/or expanding the spectrum of plant species controlled.

One potential approach to enhancing the performance of a herbicide is to combine it with one or more additional herbicides having further desired properties. The use of herbicide combinations providing multiple modes of action also can be beneficial in delaying and/or preventing the development of resistance in weeds. Where two or more herbicides are applied in combination, however, physical and/or biological incompatibility of the herbicides can sometimes be a problem. Examples of such incompatibility can include antagonism of herbicidal activity (i.e., the performance results are less than expected when the herbicides are combined), insufficient stability of the formulation comprising the herbicides, and/or decomposition of one or more of the herbicides. Suitable herbicide combinations generally should have a favorable herbicidal activity profile and good stability.

Assuming the herbicides selected for the combination are compatible, the performance results typically are no more than additive results (i.e., the herbicide combination gives the performance results expected from the sum of its individual components). In selected cases, however, a combination of two or more herbicides can provide unexpected synergistic performance results. As discussed below, Applicant has identified new synergistic combinations of herbicides. Specifically, Applicant has identified synergistic combinations of an auxin herbicide and a photosystem II inhibitor herbicide, synergistic combinations of a chloroacetanilide herbicide and a photosystem II inhibitor herbicide, synergistic combinations of an auxin herbicide and a chloroacetanilide herbicide, and the use of such synergistic combinations to control unwanted plant growth.

BRIEF DESCRIPTION OF THE INVENTION

In one aspect, the present disclosure relates to a method for controlling the growth of one or more plant species in a land area used for cultivating a crop, wherein the method comprises:

applying a first amount of an auxin herbicide to the plant species; and

applying a second amount of a photosystem II inhibitor to the plant species;

wherein the crop has a naturally occurring tolerance to one or more herbicides, or has been genetically engineered to increase tolerance to one or more herbicides; and

wherein the first amount and the second amount together produce a synergistic herbicidal effect on the plant species.

In another aspect, the present disclosure relates to a method for controlling the growth of one or more plant species in a land area used for cultivating a crop, wherein the method comprises:

applying a first amount of dicamba, or an agriculturally acceptable salt or ester thereof, to the plant species; and

applying a second amount of metribuzin, or an agriculturally acceptable salt or ester thereof, to the plant species;

wherein the crop has a naturally occurring tolerance to one or more herbicides, or has been genetically engineered to increase tolerance to one or more herbicides; and

wherein the first amount and the second amount together produce a synergistic herbicidal effect on the plant species.

In another aspect, the present disclosure relates to a method for controlling the growth of one or more plant species in a land area used for cultivating a crop, wherein the method comprises:

applying a first amount of a chloroacetanilide herbicide to the plant species; and

applying a second amount of a photosystem II inhibitor to the plant species;

wherein the crop has a naturally occurring tolerance to one or more herbicides, or has been genetically engineered to increase tolerance to one or more herbicides; and

wherein the first amount and the second amount together produce a synergistic herbicidal effect on the plant species.

In another aspect, the present disclosure relates to a method for controlling the growth of one or more plant species in a land area used for cultivating a crop, wherein the method comprises:

applying a first amount of acetochlor, or an agriculturally acceptable salt or ester thereof, to the plant species; and

applying a second amount of metribuzin, or an agriculturally acceptable salt or ester thereof to the plant species;

wherein the crop has a naturally occurring tolerance to one or more herbicides, or has been genetically engineered to increase tolerance to one or more herbicides; and

wherein the first amount and the second amount together produce a synergistic herbicidal effect on the plant species.

In another aspect, the present disclosure relates to a method for controlling the growth of one or more plant species in a land area used for cultivating a crop, wherein the method comprises:

applying a first amount of an auxin herbicide to the plant species; and

applying a second amount of a chloroacetanilide herbicide to the plant species;

wherein the crop has a naturally occurring tolerance to one or more herbicides, or has been genetically engineered to increase tolerance to one or more herbicides; and

wherein the first amount and the second amount together produce a synergistic herbicidal effect on the plant species.
