Oxime abscission agents

Abstract

A method of aiding in harvesting fruit wherein abscission is induced by application to the fruit bearing plant of an effective amount of a compound of the formula ##STR1## or a salt thereof, wherein R.sub.1 is hydrogen, halogen, alkyl, alkenyl, phenylalkyl or furyl, R.sub.2 is hydrogen, alkyl, cycloalkyl, phenyl, carboxy, carbalkoxy, carbanilido, heterocyclic or a group ##STR2## in which R.sub.1 ' has the same meanings as R.sub.1, n is an integer from 0 to 3, and wherein R.sub.1 and R.sub.2 when taken together form a C.sub.3 -C.sub.12 ring and R.sub.3 and R.sub.4 represent hydrogen, alkyl, alkenyl, alkylcarbonyl, phenylcarbonyl, N-alkylcarbamoyl, N-alkylthiocarbamoyl, N,N-dialkylcarbamoyl, phenylcarbamoyl, phenylalkyl, alkoxycarbonyl, phenoxycarbonyl, phenylalkoxycarbonyl, alkylthiocarbonyl, phenylthiocarbonyl, .alpha.-furyl and tetrahydropyranyl.
