Foliar structural differences between glyphosate-resistant and glyphosate-susceptible biotypes of Digitaria insularis (L.) Fedde [PDF]
Revista Ceres, 2023 Digitaria insularis (L.) Fedde stands out for its resistance to glyphosate and this characteristic may have a relationship with structural alterations. In such context, this research aimed at the characterization of the foliar anatomical structure of two

An individual-based model of seed- and rhizome-propagated perennial plant species and sustainable management of Sorghum halepense in soybean production systems in Argentina. [PDF]
Ecol Evol, 2019 The paper presented a novel population model for evaluating the effects of ecological, evolutionary, and anthropogenic factors on the population dynamics of perennial plant species. To exemplify the application of the model, a case study of an important weed species, Sorghum halepense, in soybean productions in Argentina was presented.

Accuracy and consistency of grass pollen identification by human analysts using electron micrographs of surface ornamentation. [PDF]
Appl Plant Sci, 2014 • Premise of the study: Humans frequently identify pollen grains at a taxonomic rank above species. Grass pollen is a classic case of this situation, which has led to the development of computational methods for identifying grass pollen species.

Ecophysiology of seed germination in Digitaria insularis ((L.) Fedde)
Revista Ciencia Agronomica, 2014 The invasive behaviour of sourgrass (Digitaria insularis) in cultivated areas is due to its strategy of aggressive regeneration, which is based on seed germination.

Impact of glyphosate formulations and adjuvants: effects on leaf interaction, metabolism, and control of sourgrass [PDF]
Ciência Rural, 2022 : The addition of commercial formulations and adjuvants to a tank mix may result in differences in the wettability on the plant surface, foliar uptake and herbicide efficacy. Thus, the objectives of this study were to evaluate the influence of glyphosate

ACCase inhibitor fractionation and glyphosate addition improve perennial sourgrass control
Semina: Ciências Agrárias, 2022 Glyphosate-resistant sourgrass is difficult to control, particularly when perennial, and strategies that improve the control efficiency against this grass and preserve the useful life of graminicides are warranted.

Growth inhibition of sourgrass as a function of period of darkness after diquat application
Bioscience Journal, 2022 Photosystem-inhibiting herbicides, such as diquat, act by inducing oxidative stress. However, oxidative damage impairs translocation, resulting in regrowth of the plants.

Sensitivity and resistance level of sourgrass population subjected to glyphosate application
Journal of Plant Protection Research, 2021 The intensive use of glyphosate in agricultural areas has increased the frequency of weeds that are resistant to herbicides. Thus, this study was aimed to assess the sensitivity and resistance level of Digitaria insularis (L.) Fedde (sourgrass ...
