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.
一种辅助收获水果的方法,其中通过向结果植物施加公式##STR1##中的化合物或其盐的有效量来诱导脱离,其中R.sub.1是氢、卤素、烷基、烯基、苯基烷基或呋喃基,R.sub.2是氢、烷基、环烷基、苯基、羧基、羧酰氧基、羧苯胺基、杂环基或一个基团##STR2##其中R.sub.1'具有与R.sub.1相同的含义,n是从0到3的整数,且当R.sub.1和R.sub.2一起形成一个C.sub.3 -C.sub.12环时,R.sub.3和R.sub.4代表氢、烷基、烯基、烷基羰基、苯基羰基、N-烷基氨基甲酰基、N-烷基硫氨基甲酰基、N,N-二烷基氨基甲酰基、苯基氨基甲酰基、苯基烷基、烷氧基羧基、苯氧基羧基、苯基烷氧基羧基、烷基硫氧基羧基、苯基硫氧基羧基、α-呋喃基和四氢吡喃基。
