Selectivity and control of Euphorbia heterophylla in sugarcane by herbicide in post-emergence

Journal of Environmental Science and Health, Part B, 2023
To obtain good control of wild poinsettia (Euphorbia heterophylla) in post-emergence in sugarcane crop, we evaluate the herbicides association on post-emergence of E. heterophylla and the ratoon cane selectivity. The experimental scheme was in randomized blocks with 6 treatments and 4 replications.

Influence of temperature on the retention, absorption and translocation of fomesafen and imazamox in Euphorbia heterophylla

Pesticide Biochemistry and Physiology, 2021
Climate change will be an additional issue to the challenge to manage herbicide resistant weeds. This work investigated the impact of three temperature regimes (10/5, 20/15 and 30/25 °C) on the efficacy, foliar retention, absorption and translocation of fomesafen, protoporphyrinogen oxidase (PPO) inhibitor, and imazamox, acetolactate synthase (ALS ...

The phytotoxic effect of exogenous ethanol on Euphorbia heterophylla L.

Plant Physiology and Biochemistry, 2009
This study investigated the effects of exogenously applied ethanol on Euphorbia heterophylla L., a troublesome weed in field and plantation crops. Ethanol at concentrations ranging from 0.25 to 1.5% caused a dose-dependent inhibition of germination and growth of E. heterophylla. Measurements of respiratory activity and alcohol dehydrogenase (E.C. 1.1.1.

Germination of Wild Poinsettia(Euphorbia heterophylla)

Weed Science, 1978
Germination studies were conducted on seed of wild poinsettia(Euphorbia heterophyllaL.) collected in 1974 and 1975. Significant differences in germination existed between the seedlots. An alternating temperature regime of 25/35 C was optimum for germination, and no effect of light was noted at this temperature regime.

Accumulation of non-utilizable starch in laticifers of Euphorbia heterophylla and E. myrsinites

Planta, 1978
Starch biosynthesis and degradation was studied in seedlings and mature plants of Euphorbia heterophylla L. and E. myrsinites L. Mature embryos, which lack starch grains in the non-articulated laticifers, develop into seedlings that accumulate starch rapidly when grown either in the light or the dark.

The Control of Milk Weed (Euphorbia Heterophylla) In Soybean with a Mycoherbicide

1992
Milk weed (wild poinsettia)(Euphorbia heterophylla) may be a classical example of a weed species that, in few years, evolved to a major problem, being selectively favored by the herbicides that controlled the other weeds but left it unaffected. An alternative biological method of control has shown great potential for practical use.

Wild Poinsettia (Euphorbia heterophylla) Germination and Emergence

Weed Science, 1995
Wild poinsettia germination was at least 95% when exposed to solution pH of 2.5 to 10 or solution osmotic potential of up to −0.8 MPa. No germination was observed at pH 12 or osmotic potential of −1.5 MPa. Light was not required for germination. Seed germinated at temperatures ranging from 20 to 40 C with maximum germination of 97% at 35 C.

Euphorbia heterophylla:a Review of Distribution, Importance and Control

Tropical Pest Management, 1981
Abstract Euphorbia heterophylla Linn., commonly known as wild poinsettia, is widespread in the tropics. It occurs as a major weed in six tropical countries, an important weed in 22 tropical countries and is present in a further 37 countries. It causes serious loss of yield and quality in a wide range of crops as it competes successfully by growing ...
