Title

Control of Amaranthus spp. using the allelopathic potential of Brassica extracts

Intervention effect Extract concentrations of 50% and 100% completely inhibited germination and seedling development of Amaranthus, compared with 0%.
Intervention effect The 12% extract concentration unexpectedly stimulated growth of all tested Amaranthus species, compared with 0%.
Intervention effect All extracts negatively affected the germination speed index of Amaranthus, with a 100% reduction at the highest concentration.
Intervention effect Hypocotyl length of Amaranthus did not differ significantly among treatments.
Intervention effect Root system development of Amaranthus was severely impaired by the extracts.
Intervention effect Shoot growth of Amaranthus was poor under the extracts.
Intervention effect Seedlings exposed to increasing extract doses showed clear phytotoxic symptoms that culminated in necrosis.
Observation Phytochemical screening detected coumarins, steroids and flavonoids in the Brassica extracts.
Observation Phytochemical screening detected phenolics, glycosides and tannins in the Brassica extracts.
Observation Phytochemical screening detected terpenes in the Brassica extracts.
Recommendation The authors suggest brassicaceous extracts may be a viable alternative for managing Amaranthus species.
