Poinsettia's wild ancestor in the Mexican dry tropics: Historical, genetic, and environmental evidence

American Journal of Botany, 2012
• Premise of the study: The poinsettia (Euphorbia pulcherrima) is the world's most economically important potted plant, but despite its preeminence it is not clear which wild populations are ancestral to the varieties cultivated around the world. Tradition holds that the U.S. envoy to Mexico J. R.

Interference of Wild Poinsettia (Euphorbia heterophylla) with Soybean (Glycine max)

open access: yesWeed Technology, 1994
Field-studies were conducted over two years to determine the area of influence and duration of interference of wild poinsettia in soybean. Soybean canopy width averaged across years was reduced approximately 10% beginning at 6 wk of interference for both the 0- to 10-and 10-to 20-cm distances from the weed.

Growth Response of Wild Poinsettia (Euphorbia heterophylla) Following Foliar Herbicide Applications

open access: yesWeed Technology, 1993
Greenhouse and field studies were conducted to characterize wild poinsettia growth response to imazaquin (140 g ai ha−1), fomesafen and acifluorfen (420 g ai ha−1), and chlorimuron (9 g ai ha−1) applied at 5 to 7 cm (POST1), 8 to 10 cm (POST2), and 15 to 20 cm (POST3). Based on reductions in weed height and lateral branch number 28 DAT, wild poinsettia

Wild poinsettia biology and management – determining optimal control with herbicides and propane flaming

Crop Protection, 2019
Abstract Wild poinsettia (Euphorbia heterophylla L.) is a troublesome weed in irrigated summer crops and orchards. Data regarding the optimal herbicide rates for control of this weed, the impact of phenology on control efficacy, and non-chemical control methods for this weed are scarce.
