Invasion dynamics of three allergenic invasive Asteraceae (Ambrosia trifida, Artemisia annua, Iva xanthiifolia) in central and easter Europe. Published PARTICIPANTS: Not relevant to this project. 47:62. (3) Despite fluctuating environmental conditions during seed development, seed weight within maternal families of A. trifida remained constant for different maturation times. Accepted Nine of the top ten most influential giant ragweed publications in agriculture-related journals, assessed as citations per publication, have been published since 2000. Associated Ecological Communities: ** Growth Habit: Herb: Duration: Annual: Category: Vascular: USDA Symbol: ** Plant Notes: Giant Ragweed is a native herbaceous annual in the Sunflower family (Asteraceae). Ambrosia - the nectar of the gods. The novel interaction of L. terrestris and A. trifida increases A. trifida seed bank formation, and L. terrestris burrows provide safe sites for A. trifida seeds that may increase seedling establishment in environments with a high risk of seed predation by other organisms. The opposite leaves are up to 12" long and 8" across. Managing giant ragweed in non-crop areas could reduce giant ragweed migration from non-crop habitats into crop fields and slow its spread. Collectively, results showed that: (1) Earthworms (Lumbricus terrestris) collected and buried over 90% of A. trifida seeds placed on the soil surface at a rate eightfold faster than abiotic seed burial. Provided by USDA NRCS Wetland Science Institute (WSI). Nothing Reported Weed Sci. Robert H. Mohlenbrock. Reference to “weed” in the title or keywords ranked 12th from 1903 to 1982 but increased to 2nd from 2003-2012. What do you plan to do during the next reporting period to accomplish the goals? 2016. Cropping System Redesign for Improved Weed Management: A Modeling Approach Illustrated with Giant Ragweed (Ambrosia trifida) Author: Liebman, Matt, Nichols, Virginia A. However, it is not a legal authority for statutory or regulatory purposes. Soc. 2007. 66:47. Results of this experiment show unique emergence behaviors among half-sib families, which helps explain the prolonged emergence of giant ragweed in Ohio crop fields.ImpactsResults of this study show that seed dormancy varies among individual mother plants within a giant ragweed population. Article title word and author keyword usage analyses showed that the word “allergy” ranked 285th from 1903 to1982 and increased to 38th from 2003-2012. In North America, A. trifida seems to prefer establishment at latitudes between 45° and 30° north because of fairly strict photoperiodic constraints for flowering, which may maximize its reproduction (Allard, 1943). Soc. Based on the database, maps illustrating the historical distribution of giant ragweed were constructed from 1852 to the present. Kuntze : Common Name(s): great ragweed [English] Texan great ragweed [English] giant ragweed [English] tall ragweed [English] blood ragweed [English] In spring of 2003, emergence was monitored on a regular basis. across with rounded base, 3-5 lobed, serrated. The effects of interplant variation on Ambrosia trifida L. emergence patterns. It is native to the central and eastern United States. Soc. Weed Sci. Reduced use of conventional tillage in corn and soybean fields was associated with increased difficulty of managing giant ragweed. Agriculture, Ecosystems, and Environment 138:197-205. Rates of seed demise were inversely proportional to burial depth, and the percentage of viable seeds remaining after four years ranged from 0% on the soil surface to 19% at the 20-cm burial depth. USDA Plant Characteristics. Dispersal unit dimensions were measured and their relationships with emergence parameters were The earthworm collects giant ragweed seeds from the soil surface and stores them in its burrow, thereby protecting the seeds from various seed predators. 25 half-sib families) were planted each autumn at a uniform depth. Abstract 222. 14:290-320. The number of authors, collaborations, and international involvement associated with giant ragweed publications has also increased dramatically over the past three decades. Weed Sci. Réglementation. Questions concentrated on giant ragweed history, prevalence, and management issues within each respondent's' geographic area of responsibility. Preslia, 85(1): 41-61. These results suggest that the invasivity of giant ragweed in agricultural fields is due in part to the weed's adaptation to agricultural weed control practices that are concentrated early in the growing season. Regnier, and R. Venkatesh. Year Published: texana Scheele : Ambrosia trifida var. 60:19-26. Where giant ragweed is already established in crop fields, incorporating diversity in crop rotations (e.g., use of a winter small grain or cover crop), tillage practices, and herbicide sites of action will be critical to reduce populations and select against late-emerging and herbicide-resistant giant ragweed genotypes.
