Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
66 words
A nematicidal composition comprising in admixture with an agriculturally acceptable carrier a nematicidally effective amount of at least one nematicidal compound of the formula ##STR7## wherein X and Y are substituents independently selected from the group consisting of lower alkoxy, phenyl, isothiocyano, trifluoromethylthio, and nitro; or Y is hydrogen and X is selected from the group consisting of lower alkoxy, phenyl, isothiocyano, trifluoromethylthio, 2-nitro, and 4-nitro.
Claim 2
Dependent Claim
66 words
A nematicidal composition comprising in admixture with an agriculturally acceptable carrier a nematicidally effective amount of at least one nematicidal compound of the formula ##STR7## wherein X and Y are substituents independently selected from the group consisting of lower alkoxy, phenyl, isothiocyano, trifluoromethylthio, and nitro; or Y is hydrogen and X is selected from the group consisting of lower alkoxy, phenyl, isothiocyano, trifluoromethylthio, 2-nitro, and 4-nitro.
Claim 3
Dependent Claim

Claim 6
Independent Claim
67 words
A method of controlling nematodes which comprises applying to or incorporating into nematode-infested soil a nematicidally effective amount of at least one nematicidal compound of the formula ##STR8## wherein X and Y are substituents independently selected from the group consisting of hydrogen, lower alkyl, lower alkoxy, phenyl, halogen, isothiocyano, trifluoromethylthio, and nitro, with the proviso that X is not 2-Br or 3-NO 2 when Y is hydrogen.
Claim 7
Independent Claim
67 words
A method of controlling nematodes which comprises applying to or incorporating into nematode-infested soil a nematicidally effective amount of at least one nematicidal compound of the formula ##STR8## wherein X and Y are substituents independently selected from the group consisting of hydrogen, lower alkyl, lower alkoxy, phenyl, halogen, isothiocyano, trifluoromethylthio, and nitro, with the proviso that X is not 2-Br or 3-NO 2 when Y is hydrogen.
