Abstract

AGRIKULTURNE KEMIKALIJE V MIKROKAPSULAH, opisan je postopek za vdelavo agrokemikalije, ki se hitro izlužuje, v mikrokapsule, ki obsega stopnje a) dodajanja suspenziji agrokemikalije v tekočini sečninsko-, tiosečninsko- ali melamin-formaldehidnega predpolimera ali njegovih zmesi, pri čemer je predpolimer ali zmes mešljiv v tekočini, in b) utrjevanja predpolimera, da dobimo zamreženi polimer, ki obdaja agrokemikalijo. Izum se nanaša tudi na mikrokapsule, dobljene po tem postopku, na sestavek, ki vsebuje te mikrokapsule, in na postopek za zatiranje neželenih škodljivcev ali rasti rastlin.AGRICULTURAL CHEMICALS IN MICROCAPPSULES, a process for incorporating a rapidly leaching agrochemical into microcapsules is described, comprising the steps of a) adding to a suspension of an agrochemical in a liquid a urea, thiourea or melamine-formaldehyde prepolymer or with its derivatives miscible in the liquid, and b) curing the prepolymer to obtain a crosslinked polymer surrounding the agrochemical. The invention also relates to microcapsules obtained by this process, to a composition comprising these microcapsules, and to a process for controlling unwanted pests or plant growth.
