Abstract

Disclosed herein are herbicidal compositions comprising a synergistic herbicidally effective amount of (a) penoxsulam or an agriculturally acceptable salt thereof, or clomazone or an agriculturally acceptable salt thereof, and (b) benzobicyclon or an agriculturally acceptable salt thereof. Also disclosed herein are methods of controlling undesirable vegetation in rice, which comprise applying to vegetation or an area adjacent the vegetation or applying to soil or water to prevent the emergence or growth of vegetation (a) penoxsulam or an agriculturally acceptable salt thereof, or clomazone or an agriculturally acceptable salt thereof, and (b) benzobicyclon or an agriculturally acceptable salt thereof, wherein (a) and (b) are each added in an amount sufficient to produce a synergistic herbicidal effect.

Claims

1. A herbicidal composition comprising herbicides, wherein the herbicides consist of a synergistic herbicidally effective amount of (a) penoxsulam or an agriculturally acceptable salt thereof, and (b) benzobicyclon or an agriculturally acceptable salt thereof, wherein the weight ratio of (a) to (b) is from 1:

15 to 1;

7.

2. The composition of claim 1, wherein the weight ratio of (a) to (b) is from 1:

10 to 1;

7.

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

4. The composition of claim 3, wherein the agriculturally acceptable adjuvant includes a safener.

5. A method of controlling undesirable vegetation in rice which comprises applying to vegetation or an area adjacent the vegetation or applying to soil or water to control the emergence or growth of vegetation a herbicidal composition comprising herbicides, wherein the herbicides consist of (a) penoxsulam or an agriculturally acceptable salt thereof, and (b) benzobicyclon or an agriculturally acceptable salt thereof, wherein the weight ratio of (a) to (b) is from 1:

15 to 1;

7.

6. The method of claim 5, wherein (a) and (b) are applied simultaneously.

7. The method of claim 5, wherein (a) and (b) are applied into water to control the emergence of undesirable vegetation.

8. The method of claim 5, wherein (a) is applied in an amount of from 5-50 g ai/ha.

9. The method of claim 5, wherein the undesirable vegetation is controlled in water-seeded or transplanted paddy rice.

10. The method of claim 5, wherein the undesirable vegetation includes a broadleaf weed, a grass weed, a sedge weed, or a combination thereof.

11. The method of claim 5, wherein the undesirable vegetation is controlled in glyphosate-, 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase inhibitor-, glufosinate-, glutamine synthetase inhibitor-, dicamba-, phenoxy auxin-, pyridyloxy auxin-, synthetic auxin-, auxin transport inhibitor-, aryloxyphenoxypropionate-, cyclohexanedione-, phenylpyrazoline-, acetyl CoA carboxylase (ACCase) inhibitor-, imidazolinone-, sulfonylurea-, pyrimidinylthiobenzoate-, triazolopyrimidine-, sulfonylaminocarbonyltriazolinone-, acetolactate synthase (ALS) or acetohydroxy acid synthase (AHAS) inhibitor-, 4-hydroxyphenyl-pyruvate dioxygenase (HPPD) inhibitor-, phytoene desaturase inhibitor-, carotenoid biosynthesis inhibitor-, protoporphyrinogen oxidase (PPO) inhibitor-, cellulose biosynthesis inhibitor-, mitosis inhibitor-, microtubule inhibitor-, very long chain fatty acid inhibitor-, fatty acid and lipid biosynthesis inhibitor-, photosystem I inhibitor-, photosystem II inhibitor-, triazine-, or bromoxynil-tolerant crops.

12. The method of claim 5, wherein the undesirable vegetation comprises a herbicide resistant or tolerant weed.

13. The method of claim 5, wherein the weight ratio of (a) to (b) is from 1:

10 to 1;

7.
