Allelopathic properties of plant extracts as potential bioherbicides

Abstract

Weeds are constant companions of plant production. For their control chemical substances, ie herbicides are used. In addition to a number of properties, the use of herbicides has numerous consequences, for the living world and for the environment, as well. Considering their negative effects, there is a need to find alternative methods of weed control. In recent decades, numerous researches have been done within the framework of biologically and eco-friendlier acceptable ways of controlling various pests, including weeds. Bioherbicides are compounds that contain microorganisms (such as bacteria or fungi), products of their metabolism, or plant extracts that have an effect on certain weed species. In this paper, the application of plant extracts that show allelopathic effects, as potential bioherbicides, in modern agricultural production, will be discussed.
