Abstract

A crop protection agent containing an active ingredient and based on a polymeric carrier, the active ingredient being adsorbed onto, dissolved in or otherwise bound to the said carrier, contains, as the polymeric carrier, a macroporous crosslinked, preferably styrene-containing, polymer having a particle size such that the said agent can be distributed by means of a conventional apparatus for applying crop protection agents, the active ingredient being taken up in the carrier by absorption.
