Abstract
Abstract Compositions and methods for combatting insects, fungal and bacterial plant pests are disclosed wherein the active ingredient is a compound of the formula Z-NH-Y wherein X is selected from the group consisting of a pyrazinyl radical bearing one to three substitutents, and pyrimidinyl and pyridazinyl radicals bearing two to three substituents; and Y represents phenyl, naphthyl, pyridyl or diazinyl bearing at least one substituent; the substituents in each case selected from the group consisting of halogen, cyano, nitro, trifluoromethyl, lower alkoxy, lower alkylthio, benzylthio, lower alkyl and amino, provided that (a) the compound bears at least four substituents of which at least two are halogen atoms, and (b) where X represents a pyrimidinyl radical and Y represents a pyridyl radical there is at least one substituent other than halogen present.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
A method of combatting insect, fungal and bacterial plant pests which comprises applying to said plants a pesticidally effective amount of a compound of the formula X--NH--Y wherein X is selected from the group consisting of a pyrazinyl radical bearing one to three substituents and a pyridazinyl radical bearing two to three substituents; and Y represents phenyl, naphthyl, pyridyl or diazinyl bearing at least one substituent; the substituents in each case being selected from the group consisting of halogen, cyano, nitro, trifluoromethyl, lower alkoxy, lower alkylthio, benzylthio, lower alkyl and amino; said compound bearing at least four substituents of which at least two are halogen atoms.
Claim 2
Independent Claim
106 words
A method of combatting insect, fungal and bacterial plant pests which comprises applying to said plants a pesticidally effective amount of a compound of the formula X--NH--Y wherein X is selected from the group consisting of a pyrazinyl radical bearing one to three substituents and a pyridazinyl radical bearing two to three substituents; and Y represents phenyl, naphthyl, pyridyl or diazinyl bearing at least one substituent; the substituents in each case being selected from the group consisting of halogen, cyano, nitro, trifluoromethyl, lower alkoxy, lower alkylthio, benzylthio, lower alkyl and amino; said compound bearing at least four substituents of which at least two are halogen atoms.
Claim 3
Dependent Claim
77 words
The method of claim 1 wherein the compound is of the formula X--NH--Y wherein X represents a halogen substituted diazinyl radical selected from the groups consisting of a pyrazinyl radical bearing from one to three halogens and a pyridazinyl radical bearing from two to three halogens; and Y is a substituted phenyl, naphthyl, pyridyl or diazinyl radical bearing at least two substituents selected from the group consisting of halogen, cyano, nitro, trifluoromethyl, methyl, methoxy, methylthio and amino.
Claim 4
Dependent Claim
114 words
A composition for combatting insect, fungal and bacterial plant pests comprising as active ingredient, a pesticidally effective amount of a compound of the formula X--NH--Y wherein X is selected from the group consisting of a pyrazinyl radical bearing one to three substituents and a pyridazinyl radical bearing two to three substituents; and Y represents phenyl, naphthyl, pyridyl or diazinyl bearing at least one substituent; the substituents in each case being selected from the group consisting of halogen, cyano, nitro, trifluoromethyl, lower alkoxy, lower alkylthio, benzylthio, lower alkyl and amino; said compound bearing at least four substituents of which at least two are halogen atoms and a major amount of a carrier for said compound.
Claim 5
Dependent Claim
114 words
A composition for combatting insect, fungal and bacterial plant pests comprising as active ingredient, a pesticidally effective amount of a compound of the formula X--NH--Y wherein X is selected from the group consisting of a pyrazinyl radical bearing one to three substituents and a pyridazinyl radical bearing two to three substituents; and Y represents phenyl, naphthyl, pyridyl or diazinyl bearing at least one substituent; the substituents in each case being selected from the group consisting of halogen, cyano, nitro, trifluoromethyl, lower alkoxy, lower alkylthio, benzylthio, lower alkyl and amino; said compound bearing at least four substituents of which at least two are halogen atoms and a major amount of a carrier for said compound.
Claim 6
Dependent Claim
89 words
A composition for combatting insect, fungal and bacterial plant pests comprising as active ingredient, a pesticidally effective amount of a compound of the formula X--NH--Y wherein X represents a halogen substituted diazinyl radical selected from the groups consisting of a pyrazinyl radical bearing from one to three halogens and a pyridazinyl radical bearing from two to three halogens; and Y is a substituted phenyl, naphthyl, pyridyl or diazinyl radical bearing at least two substituents selected from the group consisting of halogen, cyano, nitro, trifluoromethyl, methyl, methoxy, methylthio and amino.
Claim 7
Dependent Claim
89 words
A composition for combatting insect, fungal and bacterial plant pests comprising as active ingredient, a pesticidally effective amount of a compound of the formula X--NH--Y wherein X represents a halogen substituted diazinyl radical selected from the groups consisting of a pyrazinyl radical bearing from one to three halogens and a pyridazinyl radical bearing from two to three halogens; and Y is a substituted phenyl, naphthyl, pyridyl or diazinyl radical bearing at least two substituents selected from the group consisting of halogen, cyano, nitro, trifluoromethyl, methyl, methoxy, methylthio and amino.
