Glyphosate Applied at the Early Reproductive Stage Impairs Seed Production of Glyphosate-Resistant Hairy Fleabane [PDF]
Planta Daninha, 2019 : Glyphosate-resistant hairy fleabane [Conyza bonariensis (L.) Cronq.] is one of the most important weeds in the world. Among the factors that make this weed species widely distributed in the most diverse environments is the high seed production capacity

Determination of photosynthetic pigments in fleabane biotypes susceptible and resistant to the Herbicide Glyphosate [PDF]
Planta Daninha, 2014 Chlorophylls and carotenoids are the main photosynthetic pigment in plants. In the weeds, the greatest amount of photosynthetic pigments can result in high competitiveness of the species.

Herbicide Resistance in Summer Annual Weeds of Australia’s Northern Grains Region
Agronomy, 2023 For more than two decades, glyphosate has been relied on to control summer annual weeds in fallow systems in Australia’s northern grains region. With numerous cases of glyphosate resistance reported in weed species collected from this region, there are ...

Glyphosate-resistant hairy fleabane competition in RR® soybean [PDF]
Bragantia, 2014 Weed competition in the soybean causes changes in morphological and physiological characteristics that reduce the competitive ability of the crop. The objective of this study was to determine the control periods and coexistence of glyphosate-resistant hairy fleabane and its interference in morphological and photosynthetic variables and RR soybean yield.

Glyphosate translocation in hairy fleabane (Conyza bonariensis) biotypes [PDF]
Planta Daninha, 2008 The objective of this work was to evaluate the translocation of glyphosate in C. bonariensis plants resistant and susceptible to that herbicide. The 14C-glyphosate was mixed with commercial gyhphosate (800 g ha-1) and applied on the center of the adaxial face of a third node leaf, using a micro syringe, and adding 10 µL of a solution with specific ...
