Abstract
Herbicidal compositions containing (a) an amide herbicide selected from flufenacet, dimethenamid or a stereoisomer thereof, acetochlor, or metolachlor or a stereoisomer thereof, (b) fomesafen or an agriculturally acceptable salt thereof, and (c) saflufenacil are disclosed, wherein components (a), (b) and (c) are present in amounts effective to reduce the phytotoxicity of the saflufenacil. Methods of making and using herbicidal compositions containing (a) metolachlor or a stereoisomer thereof, (b) fomesafen or an agriculturally acceptable salt thereof, and (c) saflufenacil are also disclosed.
Claims16
A herbicidal composition comprising:
- (a) a herbicide selected from acetochlor, metolachlor, S-metolachlor, or a mixture of (R) and (S) isomers of metolachlor;
- (b) fomesafen or an agriculturally acceptable salt thereof;
- and
- (c) saflufenacil;
- wherein components (a), (b) and (c) are present in amounts effective to reduce the phytotoxicity of the herbicidal composition to a crop plant as compared to the phytotoxicity of an equivalent amount of saflufenacil applied without components (a) and (b).
A method for reducing phytotoxicity of herbicidal compounds on crops of cultivated plants, the method comprising:
- applying to useful plants or a locus thereof, simultaneously or in succession, herbicidally effective amounts of:
- (a) a herbicide selected from acetochlor, metolachlor, S-metolachlor, or a mixture of (R) and (S) isomers of metolachlor;
- (b) fomesafen or an agriculturally acceptable salt thereof;
- and
- (c) saflufenacil;
- wherein components (a), (b) and (c) are present in amounts effective to reduce the phytotoxicity of the applied herbicides to a crop plant as compared to the phytotoxicity of an equivalent amount of saflufenacil applied without components (a) and (b).
A method of controlling weeds selected from lambs quarters, sunflower and common ragweed, the method comprising:
- applying to the soil, locus, or foliage, of a weed selected from lambs quarters, sunflower and common ragweed, an herbicidal synergistic effect amount of (a) an amide herbicide selected from acetochlor, metolachlor, S-metolachlor, or a mixture of (R) and (S) isomers of metolachlor;
- (b) fomesafen or an agriculturally acceptable salt thereof;
- and (c) saflufenacil, wherein a, b and c are present in amounts effective to increase herbicidal activity of the herbicides towards the weeds selected to a herbicidal activity level higher than that of the expected herbicidal activity of a mixture of compared a and b with component c.
