Low level resistance of wild poinsettia biotypes to glyphosate and alternative chemical control
Bioscience Journal, 2019 In the State of Rio Grande do Sul (RS), Southern Brazil, glyphosate has not been capable of controlling wild poinsettia (Euphorbia heterophylla L.) in soybean fields, thus, suggesting resistance to this herbicide.

Formulation and pathogenicity of a bioherbicide for wild poinsettia control [PDF]
African Journal of Microbiology Research, 2020 Adequate formulation of bioproducts represents one of the most challenging aspects of bioproduct development. The incorporation of adjuvants with bioagents can positively influence product development. However, it is indispensable to evaluate the sensitivity of bioagents to these adjuvants.
