Determination of photosynthetic pigments in fleabane biotypes susceptible and resistant to the Herbicide Glyphosate [PDF]
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.

Auxin herbicide-resistant soybean technologies: a tool for managing susceptible and resistant Sumatran fleabane [PDF]
: Sumatran fleabane (Conyza sumatrensis) is one of the main herbicide-resistant weeds in Brazil posing challenges for soybean management. As an alternative to reduce its interference, genetically modified soybean cultivars resistant to auxinic herbicides,

Influence of spray volume on the control of Conyza spp. in soybean pre-sowing with burndown [PDF]
The herbicide mixture diclosulam + halauxifen appears to be an alternative for the control of Conyza spp.; however, the spray volume may result in different spray deposition effects on the target and, therefore, on the control.

Does the Glyphosate Treatment Interfere Negatively on RNA Integrity in Glyphosate-Resistant and -Sensitive Conyza bonariensis? [PDF]
: The hairy fleabane ( Conyza bonariensis (L.) Cronq.) is among the most problematic glyphosate-resistant weeds to manage around the world. In weed science, molecular approaches such as RNA sequencing (RNA-Seq) and quantitative reverse-transcription ...
