Wild Poinsettia (Euphorbia heterophylla) Control in Peanut (Arachis hypogaea)
Weed Science, 1990Wild poinsettia control in peanut was evaluated following various preplant-incorporated and postemergence herbicide applications. The addition of vernolate or alachlor to a preplant-incorporated treatment of benefin improved wild poinsettia control obtained with treatments of lactofen or paraquat plus alachlor applied at the time of peanut emergence ...

Native polyacrylamide gel electrophoresis was used in the current study to identify polymorphism in α- and β-esterase loci in leaf tissues of wild poinsettia plants for the analysis of genetic diversity and structure of populations. Seeds were collected from different plants in 12 different populations.

Wild poinsettia is a serious weed in several crops, including peanut, grown in the southeastern United States. A study was conducted over 3 yr at Jay, FL, to characterize the growth and development of wild poinsettia grown from seed collected at Plains, GA; Marianna, FL; and Baton Rouge, LA.

BioControl, 2006
Bipolaris euphorbiae (anamorphic Ascomycota: Pleosporaceae) has been studied since the early 1980s as a potential biocontrol agent of wild poinsettia (Euphorbia heterophylla), a noxious invader of soybean fields in Brazil. A new isolate (KLN05) was arbitrarily selected after the aggressiveness of six isolates of the fungus obtained from different sites

Plant extracts could be used as substitutes to synthetic pesticides in the management of fungi and other plant pathogens. The biofungicidal potential of aqueous extracts of wild poinsettia (Euphorbia heterophylla L., a weed) and African ebony (Diospyros crassiflora Hiern, a tree) leaves, and Ashanti pepper (Piper guineense Schumach., a spice) seeds was
