Conversely, L. terrestris cached more seeds than were consumed by seed predators in areas with low vegetative cover. It is native to North America, where it is widespread in Canada, the United States, and northern Mexico. Some seeds recovered from the 20-cm burial depth were viable after nine years of burial. A common American composite weed ({Ambrosia artemisi[ae]folia}) with finely divided leaves; hogweed. Synonym Full Citation Basionym Type; Ambrosia aptera Ambrosia aptera DC. It is likely that giant ragweed spreads initially through a variety of non-crop edge habitats and then becomes established in areas adjacent to crop fields such as waterways and fencerows, and from there it can quickly get established in crop fields.

Conference Papers and Presentations Ambrosia trifida Linnaeus: Common Name: Giant Ragweed; Great Ragweed: Habitat: Open, disturbed sites. Regulation. Based on the survey responses, giant ragweed was reported to appear in crop fields 20 years ago or longer in western Ohio, most of Indiana, northern Illinois, southern Wisconsin, southeastern Minnesota, and eastern Iowa. (2) Cumulative percent emergence of A. trifida in central OH increased rapidly in early spring and reached 60% of maximum by late April, leveled off for a period in May, and increased again at a lower rate before concluding in late July. It can be found throughout Alabama. “Ambrosia trifida (Great Ragweed) - Plate 23.” Special Collections, USDA National Agricultural Library. Nearly all respondents indicated that giant ragweed was already present in non-crop edge habitats such as riverbanks and fencerows before it appeared in crop fields. Disclaimer: ITIS taxonomy is based on the latest scientific consensus available, and is provided as a general reference source for interested parties. Results suggest that giant ragweed is increasing in crop fields outward from the east-central U.S. Corn Belt in all directions. A. trifida grows in its natural habitat in North America where it initially inhabited mainly river valleys, floodplains, drainage channels, moist disturbed open sites and others (AMBROSIA TRIFIDA (ASTERACEAE), A NEW NON-NATIVE SPECIES FOR THE BULGARIAN FLORA). Usage Requirements. North Cent. Influence of seed burial by earthworms and seed predation by vertebrates on seedling recruitment in giant ragweed. Am. Nothing Reported The apparent facilitation of A. trifida colonization by L. terrestris has the potential to change actions of crop producers and land managers in new efforts to manage and control A. trifida, a highly competitive weed of crops and a plant that directly impacts human health through the release of allergenic pollen. 4) Key outcomes or other accomplishments realized: Results suggest that giant ragweed is increasing in crop fields outward from the east-central Corn Belt, facilitated by the pre-existence of populations in non-crop habitats and a favorable habitat provided by similar crop rotation, tillage and herbicide practices across much of the Corn Belt. Provided by USDA NRCS Wetland Science Institute (WSI). The model predicted that ≥ 98% of total cumulative emergence was completed after four growing seasons for large seeds buried 5-cm, five The enigma surrounding A. trifida is that despite its low seed production, high seed consumption by mice and beetles, and large seed size hindering burial in the soil, it persists in untilled soils in addition to crop fields. Ambrosia trifida is a native annual and major agricultural and allergenic weed advancing north and westward in the U.S.. Nine of the top ten most influential giant ragweed publications in agriculture-related journals, assessed as citations per publication, have been published since 2000. Ambrosia trifida L 2010. Year Published: Crop production practices associated with giant ragweed populations included minimum tillage, continuous soybean, and multiple-application herbicide programs; ecological factors included giant ragweed presence in non-crop edge habitats, early and prolonged emergence period, and presence of the seed-burying common earthworm in crop fields.
