Callelo: a novel bioherbicide
Huron Park S.S.

Alliaria petiolata (garlic mustard) and Coffea arabica (coffee) have both been found to inhibit germination through the production of allelochemicals. When combined in a 50/50 ratio, aqueous extracts of both compounds applied three times were able to significantly inhibit germination and seedling growth after statistical analysis. This compound shows promise as an economical and environmentally friendly herbicide.
