M. Johnston Family: Amaranthaceae . Ind. 1918. Amaranthus retroflexus komt oorspronkelijk uit N-Amerika maar komt nu ook voor in bijna gans Europa. Fall moldboard plowing in plots with high seed populations reduced redroot pigweed emergence the following spring by more than 90 percent (from 3,500 to 250 per 10 square feet), but plowing fields in which seed production had been prevented for six years brought deeply buried seeds to the surface, and thereby increased emergence from 1 to 25 per 10 square feet.
