Pesticidally active 2-anilino-3,5-dinitrobenzotrifluorides of the formula: ##STR1## WHEREIN R is hydrogen, methyl or methoxy; X is halogen,

Dinitroaniline derivatives

Compositions and methods for combating insect pests or fungal pests of plants wherein the active component is a diphenylamine derivative of the formula: ##STR1## WHEREIN EITHER (A) Q represents a cyano or trifluoromethyl group, and X represents a halogen atom, m is an integer from zero to three, n is zero or one, p is an integer from zero to two, and q is an integer from zero to three, the sum of m, n, p and q being an integer from two to five; or (b) Q represents a nitro group and X represents a halogen atom, m is an integer from zero to three, n is zero or one, p is an integer from zero to two, and q is an integer from zero to three, the sum of n and p being an integer from one to three, and the sum of m, n, p and q being an integer from two to five.

Compositions and methods for combating insect pests or fungal pests of

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.

Certain diazines as plant pesticides

The present invention relates to polysubstituted aryl amino pyridines herbicidal and pesticidal compositions useful, inter alia, in controlling pests including fungal infections of plants, and in inhibiting the growth of unwanted vegetation; to chemical compounds useful as active ingredients of such compositions; to methods of controlling pests including fungal infections of plants: and to methods of inhibiting the growth of unwanted vegetation.

Certain aryl amino pyridines

A group of 4-cyano-or 4-trifluoromethyl-2,6 dinitrodiphenylamine derivatives are very toxic to a wide variety of insect and other invertebrate pests.

Diphenylamine derivatives

Pesticidal compounds of formula I where Z represents a halo-substituted naphthyl group or a group of formula II wherein X.sup.1, X.sup.2, X.sup.3 and X.sup.4 are halogen, and Y is halogen, trifluoromethyl, nitro or alkyl: ##SPC1##
