Digitaria sanguinalis (L.) Scop. Digitaria sanguinalis is a troublesome annual weed that causes important yield losses in different crops. The typical variety has spikelets 2.5-3.0 mm long and sterile lemma appressed - pubescent. In several cases, a well-defined weed control could be able predict the seed emergence, to know the to physiological status of the seeds in the soil bank, as well as, the factors that control and involving their germination. Habitat Explanation; Agricultural areas: Under cultivation: Arctic/alpine: Arctic/alpine vegetation types (latitude and altitude aspects involved) Boreal forest Koeler][Digitaria sanguinalis (L.) Scop. Digitaria sanguinalis. Spodoptera frugiperda is a polyphagous pest with a host range (observed in the Americas) of 353 plants belonging to 76 families, mainly Poaceae, Asteraceae and Fabaceae (Montezano et al., 2018).The greatest damage is observed in grasses, particularly maize and sorghum, which are the main hosts, along with other crops, such as rice, cotton and soybean (Casmuz et al., 2010; Montezano et al., 2018). This weed has had many names, among which D. adscendens may still be quite often used, though D. ciliaris is generally regarded as the preferred name. Les épillets des Digitaria spp. They are slender monocotyledonous annual and perennial lawn, pasture, and forage plants; some are often considered lawn pests. 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. Digitaria spp. In several cases, a well-defined weed control could be able to predict the seed emergence, to know the physiological status of the seeds in the soil bank, as well as, the factors that control and involving their germination.

The speed of wrack movement varied substantially among days, ranging from 1.1 ± 0.03 to 2.6 ± 0.08 km h −1 (mean ± S.E., n = 5). The dominant species, except turf (Zoysia japonica), were Conyza canadensis, Setaria viridis, Digitaria sanguinalis and Aster tripolium. Secondary Noxious, Class 4 and Noxious, Class 5 in the Canadian Weed Seeds Order, 2016 under the Seeds Act.. Distribution. History of use/introduction. Trials included four common agricultural weed species, i.e., crabgrass (Digitaria sanguinalis), giant foxtail (Setaria faberii), pigweed (Amaranthus retroflexus), and velvetleaf (Abutilon theophrasti). Parl.] This plant is an annual weed, forms adventitious roots at the stem nodes, and is mainly propagated by seeds. Flickr photos, groups, and tags related to the "Digitaria sanguinalis" Flickr tag. The limited knowledge concerning the dispersal, sur vival and the occurrence of alternative hosts for the patho gen has compromised the development of disease control strategies. King, Lawrence R.
