Method and composition for inducing fruit abscission

Abstract

Abstract WHERE R, R2, R3 and R5 are selected from the group consisting of C2-C20 alkyl, hydrogen, halo, cycloalkyl, aryl, substituted aryl, and haloalkyl; and R1 and R4 are selected from the group consisting of hydrogen lower-alkyl, aryl, haloalkyl, halothioalkyl, arylthio, alkylthio, substituted arylthio, hydroxyalkyl, hydroxyhaloalkyl, alkylcarbamoyl, dialkylcarbamoyl, aryl substituted carbamoyl, substituted diarylcarbamoyl, alkylarylcarbamoyl, alkylsulfonyl, haloalkylsulfonyl, arylsulfonyl, substituted arylsulfonyl, formyl, carboalkoxy, carboalkoxy, pyranyl, thiocarbamoyl, halocarboalkoxy, aroyl, substituted aroyl, aryloxyaceto, substituted aryloxyaceto, arylthioaceto, substituted arylthioaceto, benzyl substituted benzyl, phenacetyl, substituted phenacetyl, phosphonoalkyl, thiophosphonoalkyl, and acetylanilide with the proviso that when R5 is chloro and R3 is hydrogen, the nitrogen in the one position is substituted. WHERE R, R2, R3 and R5 are selected from the group consisting of alkyl, hydrogen, halo, cycloalkyl, aryl, substituted aryl and haloalkyl; and R1 and R4 are selected from the group consisting of hydrogen, loweralkyl, aryl, substituted aryl, haloalkyl, halothioalkyl, arylthio, alkylthio, substituted arylthio, hydroxyalkyl, hydroxyhaloalkyl, alkylcarbamoyl, dialkylcarbamoyl, aryl substituted carbamoyl, substituted diarylcarbamoyl, alkylarylcarbamoyl, alkylsulfonyl, haloalkylsulfonyl, arylsulfonyl, substituted arylsulfonyl, formyl, carboalkoxy, carboaryloxy, pyranyl, thiocarbamoyl, halocarboalkoxy, aroyl, substituted aroyl, aryloxyaceto, substituted aryloxyaceto, arylthioaceto, substituted arylthioaceto, benzyl, substituted benzyl, phenacetyl, substituted phenacetyl, phosphonoalkyl, thiophosphonoalkyl, acetylanilide and metallic salts of any of the foregoing R1 and R4 groups, in an agronomically acceptable carrier. Also covers certain 4-nitropyrazoles having a formula selected from the group consisting of: Covers a method of inducing abscission of fruit by applying a chemical composition containing an effective amount of a 4nitropyrazole as the active ingredient in an agronomically acceptable carrier. Said composition comprises in addition to said carrier an effective amount of a compound having a formula selected from the group consisting of:
