Hybridization Between Amaranthus Tuberculatus and Amaranthus Hybridus
… related species. Studies have shown that weedy Amaranthus species are capable of interspecific hybridization, and hybridization may foster the evolution of herbicide resistance. Yet, much remains unknown as to the dynamics of Amaranthus interspecies gene flow. The research presented in this …

Growth Analyses and Patterns of Cross-Resistance in Four Imidazolinone-Resistant Smooth Pigweed (Amaranthus hybridus) Populations
Studies were conducted in 1996 through 1999 to: (1) evaluate the responses of one imidazolinone (IMI)-susceptible (S) and four -resistant (R1, R2, R3, and R4) smooth pigweed populations to various acetolactate synthase (ALS)-inhibiting herbicides, (2) determine the mechanism of resistance, and (3) …

Crop and herbicide rotation effects on weed population dynamics and the characterization of imidazolinone-resistant smooth pigweed (Amaranthus hybridus)
Shifts in weed populations to herbicide-resistant biotypes are occurring more frequently. In two adjacent field studies from 1991 through 1994, crop rotations and herbicide programs affected control and densities of common lambsquarters, common ragweed, smooth pigweed, redroot pigweed, jimsonweed, …

Exploring Diversified Vineyard Ecological Soil Management Strategies: Impacts of cover cropping, Spanish River Carbonatite, and smooth pigweed (Amaranthus hybridus) interactions on an agroecosystem
… additional experiment aimed to determine whether Amaranthus hybridus, a known allelopathic plant species present in the vineyard, affects the same cover crop species germination and growth using an A. hybridus tea extract treatment in controlled conditions. Here, A. hybridus was found to inhibit …

The Effects of Chemical Modification Upon Herbicide Binding in Thylakoid Membranes of Spinacia Oleracea (Spinach) and Amaranthus Hybridus (Pigweed), and The Photochemical Reaction Center of Rhodobacter Sphaeroides R26
Dicyclohexylcarbodiimide inhibits electron transfer between Q$\sb{\rm A}$ and Q$\sb{\rm B}$ in both higher plants and photosynthetic bacteria in an analogous manner to that seen for the classic Photosystem II inhibitors such as diuron and atrazine. It does not bind to the same binding domain as …

Herbicide-based Weed Management Systems for Potato (<i>Solanum tuberosum</i>) and Wheat (<i>Triticum aestivum</i>) and Growth and Reproductive Characteristics of Smooth Pigweed (<i>Amaranthus hybridus</i>)
… biological characteristics of smooth pigweed (<i>Amaranthus hybridus</i>), a troublesome species in many crops. Sulfentrazone is an herbicide registered for use in soybean [<i>Glycine max</i> (L.) Merr.] and tobacco (<i>Nicotiana tabacum</i> L.) that may also have potential for use in potato. In …

Efficacy, Phytotoxicity, and Cover Crop Response of Herbicide Combinations in Dark Fire Cured Tobacco
… Ipomoea hederacea L. (Ivyleaf morningglory), Amaranthus hybridus L. (smooth pigweed), and Eleusine indica L. (goosegrass). Crop injury and weed control evaluations were recorded on a 0-100% scale with 0 representing no injury and/or no control and 100 representing plant death. After crop …

Weed Control in Cucumber Cucumis sativus, Pumpkin Cucurbita maxima, and Summer Squash Cucurbita pepo with Halosulfuron
… (Ambrosia artemisiifolia L.) and smooth pigweed (Amaranthus hybridus L.). Postemergence halosulfuron controlled common ragweed, smooth pigweed, morningglory species (Ipomoea spp.), yellow nutsedge, and rice flatsedge (Cyperus iria L.). All four crops treated with halosulfuron produced yields equal …
