Suppressing weed germination using allelopathy of Alliaria petiolata
Huron Park S.S.

Alliaria petiolata is a successful invasive species in North America because it produces an allelochemical which inhibits germination. This experiment investigated if an extract of this chemical could be used to inhibit the germination of weeds in standing crops. After several pilot experiments, it was discovered that a 500g/L extract was able to significantly reduce seedling total length, root length and germination.
