Cover Story: Poly(L-lactide-co-glycolide)-block-poly (ethylene oxide) copolymer modified by blending with grafted dextrin or maltodextrin demonstrate very useful feature of this material as a biodegradable polymeric matrix for controlled release system of herbicides. The modification PLAGA/PEG copolymer by blending with modified dextrin affects the improvement of the release profile of active agent via enhancement of susceptibility of polymeric carrier to enzymatic degradation. This type of degradation allowed for the leaching of tested herbicides into the soil within few months which is very required from agrochemical and environmental protection point of view, because active substances are released through the whole vegetation period of cultivated plants.
