## Abstract

Provided herein are herbicidal compositions containing (a) aminopyralid or an agriculturally acceptable salt or ester thereof and (b) propanil. The compositions provide synergistic weed control of undesirable vegetation, e.g., in rice, wheat, barley, oats, rye, sorghum, corn or maize, oilseed rape/canola, vegetables, pastures, grasslands, rangelands, fallowland, turf, tree and vine orchards, industrial vegetation management or rights-of-way.

## Claims

### Claim 1

A herbicidal composition comprising a synergistic herbicidally effective amount of:
(a) aminopyralid, a compound of the formula (I)
or an agriculturally acceptable salt or ester thereof, and
(b) propanil, a compound of the formula (II)
wherein the ratio of (a) to (b) is from about 1:480 to about 1:15.

### Claim 2 (depends on 1)

The composition of claim 1, wherein (a) is the triisopropanolammonium salt or choline salt of compound (I).

### Claim 3 (depends on 1)

The composition of claim 1, wherein (a) is the compound of formula (I), which is the carboxylic acid.

### Claim 4 (depends on 1)

The composition of claim 1, wherein the ratio is from about 1:240 to about 1:30.

### Claim 5 (depends on 4)

The composition of claim 4, wherein the ratio is from about 1:120 to about 1:60.

### Claim 6 (depends on 1)

The composition of claim 1, further comprising an agriculturally acceptable adjuvant or carrier.

### Claim 7 (depends on 1)

A method of controlling undesirable vegetation which comprises contacting the vegetation or the locus thereof with or applying to the soil or water the composition of claim 1.

### Claim 8

A method of controlling undesirable vegetation which comprises contacting the vegetation or the locus thereof with or applying to the soil or water a synergistic herbicidally effective amount of:
(a) aminopyralid, a compound of the formula (I)
or an agriculturally acceptable salt or ester of thereof, and
(b) propanil, a compound of the formula (II)
wherein the ratio of (a) to (b) is from about 1:480 to about 1:15.

### Claim 9 (depends on 8)

The method of claim 8, wherein the undesirable vegetation is controlled in rice, wheat, barley, oats, rye, sorghum, corn, maize, pastures, grasslands, rangelands, fallowland, turf, tree and vine orchards, industrial vegetation management or rights of way.

### Claim 10 (depends on 8)

The method of claim 8, wherein the undesirable vegetation is mature or immature.

### Claim 11 (depends on 10)

The method of claim 10, wherein the water is part of a flooded rice paddy.

### Claim 12 (depends on 8)

The method of claim 8, wherein the (a) and (b) are applied pre-emergence.

### Claim 13 (depends on 8)

The method of claim 8, wherein the (a) and (b) are applied post-emergence.

### Claim 14 (depends on 8)

The method of claim 8, wherein the undesirable vegetation is controlled in glyphosate-, glufosinate-, dicamba-, phenoxy auxins-, pyridyloxy auxins-, aryloxyphenoxypropionates-, acetyl CoA carboxylase inhibitors-, imidazolinones-, acetolactate synthase inhibitors-, 4-hydroxyphenyl-pyruvate dioxygenase inhibitors-, protoporphyrinogen oxidase inhibitors-, triazines- or bromoxynil-tolerant crops.

### Claim 15 (depends on 14)

The method of claim 14, wherein the tolerant crop possesses multiple or stacked traits conferring tolerance to multiple herbicides or inhibitors of multiple modes of action.

### Claim 16 (depends on 8)

The method of claim 8, wherein the undesirable vegetation comprises a herbicide resistant or tolerant weed.

### Claim 17 (depends on 16)

The method of claim 16, wherein the resistant or tolerant weed is a biotype with resistance or tolerance to multiple herbicides, multiple chemical classes, or inhibitors of multiple herbicide modes-of-action.

### Claim 18 (depends on 16)

The method of claim 16, wherein the resistant or tolerant weed is a biotype resistant or tolerant to acetolactate synthase inhibitors, photosystem II inhibitors, acetyl CoA carboxylase inhibitors, synthetic auxins, photosystem I inhibitors, 5-enolpyruvylshikimate- 3-phosphate synthase inhibitors, microtubule assembly inhibitors, lipid synthesis inhibitors, protoporphyrinogen oxidase inhibitors, carotenoid biosynthesis inhibitors, very long chain fatty acid inhibitors, phytoene desaturase inhibitors, glutamine synthetase inhibitors, 4-hydroxyphenyl-pyruvate-dioxygenase inhibitors, mitosis inhibitors, cellulose biosynthesis inhibitors, herbicides with multiple modes-of-action, quinclorac, arylaminopropionic acids, difenzoquat, endothall, or organoarsenicals.
