Interference of large crabgrass (Digitaria sanguinalis) with snap beans
Weed Science, 2003Abstract 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).

Digitaria sanguinalis is a competitive and annual grass weed that commonly infests crops across the world. In recent years, the control of D. sanguinalis by nicosulfuron has declined in Hebei Province, China. To determine the resistance mechanisms of D. sanguinalis to nicosulfuron, a population of D.

Journal of Agricultural and Food Chemistry, 2013
Three chemicals, veratric acid, maltol, and (−)-loliolide, were isolated from crabgrass and their structures were identified by spectroscopic analysis. The chemicals were detected in crabgrass root exudates and rhizosphere soils, and their concentrations ranged from 0.16 to 8.10 μg/g.

Importancia de la autopolinización en Digitaria sanguinalis
2017Se 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 ...

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.

Characterization of a nitrogen-fixing bacterial strain from the roots of Digitaria sanguinalis
Canadian Journal of Microbiology, 1976Rates 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

Omics analysis reveals key genes mediating herbicide resistance in Digitaria sanguinalis
Pesticide Biochemistry and PhysiologyDigitaria sanguinalis (L.) Scop is recognized as one of the most problematic agricultural weeds, with chemical control remaining a crucial management strategy. However, increased selection pressures have led to the emergence of resistant populations that reproduce and establish themselves as dominant communities, thereby severely jeopardizing crop ...

Postemergence Control of Large Crabgrass (Digitaria sanguinalis) with Herbicides
Weed Science, 1991Four 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.

AbstractUnderstanding host–pathogen evolutionary dynamics needs characterisation and quantification of processes occurring at many spatiotemporal scales. With this aim, the effects of smut on a naturally infected population of the summer annual Digitaria sanguinalis were followed for 4 years in an uncropped field.

Interaction of Bromoxynil and Postemergence Graminicides on Large Crabgrass (Digitaria sanguinalis)
Weed Technology, 1998The effect of bromoxynil on large crabgrass control by clethodim, sethoxydim, fluazifop-P, fluazifop-P plus fenoxaprop-P, and quizalofop-P was evaluated in 1996 and 1997 in bromoxynil-tolerant cotton and in fallow areas. Bromoxynil at 560 g ai/ha reduced large crabgrass control 4 weeks after treatment (WAT) when mixed with labeled rates of fluazifop-P,
