Accuracy and consistency of grass pollen identification by human analysts using electron micrographs of surface ornamentation [PDF]

Applications in Plant Sciences, Volume 2, Issue 8, August 2014., 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.

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

Growth inhibition of sourgrass as a function of period of darkness after diquat application [PDF]

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.

Ecophysiology of seed germination in Digitaria insularis ((L.) Fedde)

Revista Ciência Agronômica, 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.

Control of Digitaria insularis (L.) Fedde in eucalyptus forests: shading increases sensitivity to glyphosate applied alone and in a mixture with carfentrazone-ethyl

Discover Agriculture
Shading, the predominant condition in most of the eucalyptus cultivation cycle, causes changes in the morphological and physiological weed's characteristics, which can alter their responses to glyphosate and carfentrazone-ethyl, important herbicides for ...

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.
