Abstract
The present technology is a novel method for reducing the phytotoxicity of herbicides to sugar cane plants, which comprises applying to the sugar cane propagation material, prior to sowing, a phytotoxicity reducing effective amount of a Formula (II) and/or Formula (III); or an agronomically acceptable salt of said compounds.
Claims17
A method for protecting sugar cane against the harmful of effects of herbicides comprising:
- applying, to a sugar cane propagation material, a herbicidally antagonistically effective amount of a N-acylsulfamoylphenylurea of the formula (II) or formula (III):
- or an agronomically acceptable salt of said compounds, wherein:
- Ra is selected from the group consisting of halogen, nitro, C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 haloalkoxy, C3-C6 cycloalkyl, phenyl, C1-C4 alkoxy, cyano, C1-C4 alkylthio, C1-C4 alkylsulfinyl, C1-C4 alkylsulfonyl, C1-C4 alkoxycarbonyl and C1-C4 alkylcarbonyl;
- and
- Rb and Rc are independently selected from the group consisting of hydrogen, C1-C6 alkyl, C3-C6 cycloalkyl, C3-C6 alkenyl and C3-C6 alkynyl.
A method of reducing the phytotoxicity of herbicides to sugar cane plants, the method comprising:
- applying to a sugar cane propagation material, prior to sowing the propagation materiel, a phytotoxicity reducing effective amount of a N-acylsulfamoylphenylurea of the formula (II) or formula (III):
- or an agronomically acceptable salt of said compounds, wherein:
- Ra is selected from the group consisting of halogen, nitro, C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 haloalkoxy, C3-C6 cycloalkyl, phenyl, C1-C4 alkoxy, cyano, C1-C4 alkylthio, C1-C4 alkylsulfinyl, C1-C4 alkylsulfonyl, C1-C4 alkoxycarbonyl and C1-C4 alkylcarbonyl;
- and
- Rb and Rc are independently selected from the group consisting of hydrogen, C1-C6 alkyl, C3-C6 cycloalkyl, C3-C6 alkenyl and C3-C6 alkynyl.

Sugarcane propagation material treated with a phytotoxicity reducing effective amount of a N-acylsulfamoylphenylurea of the formula (II) or formula (III):
- or an agronomically acceptable salt of said compounds, wherein:
- Ra is selected from the group consisting of halogen, nitro, C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 haloalkoxy, C3-C6 cycloalkyl, phenyl, C1-C4 alkoxy, cyano, C1-C4 alkylthio, C1-C4 alkylsulfinyl, C1-C4 alkylsulfonyl, C1-C4 alkoxycarbonyl and C1-C4 alkylcarbonyl;
- and
- Rb and Rc are independently selected from the group consisting of hydrogen, C1-C6 alkyl, C3-C6 cycloalkyl, C3-C6 alkenyl and C3-C6 alkynyl.
The sugarcane propagation material of claim 7, wherein the N-acylsulfamoylphenylurea is of the formula (III) as defined in claim 8, and wherein Ra is C1-C4 alkoxy;
- Rb is C1-C6 alkyl;
- and Rc is hydrogen.
A method of selectively controlling weeds at a locus having planted sugar cane propagation material and weeds present, the method comprising:
- applying to the locus, a weed controlling amount of a herbicide;
- and wherein the sugar cane propagation material is treated with phytotoxicity reducing effective amount of a N-acylsulfamoylphenylurea of the formula (II) or formula (III):
- or an agronomically acceptable salt of said compounds, wherein:
- Ra is selected from the group consisting of halogen, nitro, C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 haloalkoxy, C3-C6 cycloalkyl, phenyl, C1-C4 alkoxy, cyano, C1-C4 alkylthio, C1-C4 alkylsulfinyl, C1-C4 alkylsulfonyl, C1-C4 alkoxycarbonyl and C1-C4 alkylcarbonyl;
- and
- Rb and Rc are independently selected from the group consisting of hydrogen, C1-C6 alkyl, C3-C6 cycloalkyl, C3-C6 alkenyl and C3-C6 alkynyl.
