Sourgrass densities affecting the initial growth and macronutrient content of coffee plants Densidades de capim-amargoso afetando o crescimento inicial e o teor de macronutrientes do cafeeiro [PDF]
Planta Daninha, 2013 The objective of this work was to evaluate the coexistence effects of coffee (Coffea arabica) with densities of sourgrass (Digitaria insularis) on crop macronutrient content and plant growth.

The intensity of non-target site mechanisms influences the level of resistance of sourgrass to glyphosate [PDF]
Communications in Plant Sciences, 2014 Non-target site mechanisms are involved in the resistance of sourgrass (Digitaria insularis) to glyphosate. Studies on the 14C-glyphosate absorption and translocation as well as the detection of glyphosate and its metabolites in sourgrass plants were ...

Differential response of two sourgrass populations to glyphosate [PDF]
Communications in Plant Sciences, 2013 The repetitive use of glyphosate may cause increase on the resistance of sourgrass (Digitaria insularis) through mechanisms of natural selection. The aim of this study was to verify the response of two populations of sourgrass (one collected from ...

Periods of sourgrass interference in the soybean
Revista Ciência AgronômicaSourgrass (Digitaria insularis) is one of the principal weeds in Brazil, and there are reports of its being glyphosate-resistant. The aim of this study was to determine the coexistence period of the TMG7063 IPRO soybean cultivar with a weed community ...

SOURGRASS PHENOLOGICAL STAGE AND EFFICACY OF GLUFOSINATE-AMMONIUM
, 2022 Recently, biotypes of sourgrass (Digitaria insularis) were identified in Brazil with multiple resistance to EPSPs-ACCase inhibiting herbicides, what demands the recommendation of herbicides with alternative mode of action, such as glufosinate-ammonium ...

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.

Applied and Environmental Soil Science, Volume 2023, Issue 1, 2023., 2023 Compacted soils may be negatively affecting the selectivity of herbicides applied in preemergence in the soybean crop. Therefore, the present work aimed to investigate possible negative effects on the morphophysiological characters of soybean plants, as well as on the agronomic and yield performances of this crop.

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
