The nucleotide sequence of a geminivirus from Digitaria sanguinalis

Virology, 1987
The encapsidated single-stranded circular DNA of a geminivirus isolated from Digitaria sanguinalis has been sequenced. The data obtained are consistent with there being one DNA circle of 2701 nucleotides. Comparison of the nucleotide sequence with those of maize streak virus (MSV) and wheat dwarf virus showed 64 and 47% DNA homology, respectively.

Digitaria sanguinalis seed dormancy release and seedling emergence are affected by crop canopy and stubble

, 2020
Digitaria sanguinalis is a troublesome annual weed that causes important yield losses in different crops. Despite this, there is scarce information about different aspects of its biology under field conditions.

Interference of large crabgrass (Digitaria sanguinalis) with snap beans

Weed Science, 2003
Abstract Field experiments were conducted to determine the effect of large crabgrass densities of 0.5 to 8 plants m−1 of row and emergence time on snap bean yield. Large crabgrass was planted either along with snap beans (early) or when the first trifoliate leaf of snap beans was opening (late).

Large Crabgrass (Digitaria sanguinalis) and Palmer Amaranth (Amaranthus palmeri) Intraspecific and Interspecific Interference in Soybean

Weed science, 2019
Field studies were conducted in 2016 and 2017 at Clinton, NC, to quantify the effects of season-long interference of large crabgrass [Digitaria sanguinalis (L.) Scop.] and Palmer amaranth (Amaranthus palmeri S. Watson) on ‘AG6536’ soybean [Glycine max (L.

Importancia de la autopolinización en Digitaria sanguinalis

2017
Se realizaron dos experimentos para establecer el nivel de autopolinización de plantas de Digitaria sanguinalis. Para prevenir la polinización cruzada, las inflorescencias fueron tapadas. En la fase de senescencia se recolectaron las inflorescencias, se contaron los racimos espiciformes, se midió su longitud y se contaron y pesaron las espiguillas con ...

Demography of Digitaria sanguinalis: Effect of the emergence time on survival, reproduction, and biomass

Weed Biology and Management, 2010
Knowledge of weed population dynamics is crucial for designing effective weed management practises. A field experiment was carried out at Torre Marimon (near Barcelona, north‐eastern Spain) in 2006 and 2007 in order to study the effects of the seedling emergence time on Digitaria sanguinalis fitness.

Roadside Habitats: The Impact of Salinization on the Occurrence, Growth and Reproduction of Two Weed Species Echinochloa crus-galli and Digitaria sanguinalis

Polish Journal of Ecology, 2019
The specific conditions in habitats in the immediate vicinity of roads provide a suitable environment for noxious weeds and invasive species that spread through them to the landscape. Echinochloa crus-galli and Digitaria sanguinalis are problematic weeds

Characterization of a nitrogen-fixing bacterial strain from the roots of Digitaria sanguinalis

Canadian Journal of Microbiology, 1976
Rates of nitrogen fixation of 3 to 10 g of N2 fixed per hectare per day were associated with root systems of Digitaria sanguinalis. A Gram-negative motile aerobic bacterial strain that was capable of N2 fixation was isolated from a washed root sample of one of these plants. Optimal growth and N2 fixation occurred at a pH of about 6.5, a temperature of

Emergence of garden spurge (Euphorbia hirta) and large crabgrass (Digitaria sanguinalis) in response to different physical properties and depths of common mulch materials

Weed technology, 2019
Greenhouse and outdoor container experiments were conducted to determine garden spurge and large crabgrass emergence when seeds were placed either on top of or below three different mulch materials [pine bark (PB), hardwood (HW), or pine straw (PS ...

Postemergence Control of Large Crabgrass (Digitaria sanguinalis) with Herbicides

Weed Science, 1991
Four field locations were used to compare environmental factors on efficacy of four postemergence grass herbicides in Kentucky bluegrass and bermudagrass turf. Imazaquin, BAS 514, and tridiphane were compared to fenoxaprop-ethyl, a registered herbicide, for postemergence control of large crabgrass.
