Abstract
Etherified tri-butylphenol alkoxylates of the formula (I), wherein R represents an unbranched or branched, saturated or unsaturated C1-C4 alkyl, and A represents an ethylene group, a 1,2-propylene group, a 1,2-butylene group or mixtures of ethylene oxide groups and 1,2-propylene groups or mixtures of ethylene oxide groups and 1,2-butylene groups, and m is a number from 2 to 30, are suitable for improving the action of agrochemical active substances in and on plants.
Claims11
