Study on the use of weed plants as bioherbicides: a review

Abstract

Weeds are plants that are detrimental to cultivated plants if they live in the same area of life. The losses caused include reducing the production of cultivated plants. One effort to control weeds is the use of synthetic herbicides. However, excessive use of synthetic herbicides can cause problems, including reducing soil fertility, increasing weed resistance to herbicides and leaving residue. If herbicide residues are absorbed by plants and then the plants are eaten by humans, they can settle in the body and cause disease. This has triggered many researchers to look for other alternatives for weed control, namely environmentally friendly control. One of them is the use of bioherbicides. Weeds are one of the plants that have the potential to be used as bioherbicides. The ability of weed allelopathic compounds to inhibit growth has been used as a basis for developing bioherbicides. This article reviews weeds that have potential as bioherbicides, and the mechanisms of inhibition by allelochemical compounds.
