Phytotoxin produced by Bipolaris euphorbiae in-vitro is effective against the weed Euphorbia heterophylla [PDF]

Brazilian Archives of Biology and Technology, 2002
Four virulent strain isolates of the fungus, Bipolaris euphorbiae (previously identified as a Helminthosporium sp.), isolated from host plants in four states within Brazil were screened for the production of phytotoxins that promoted wilting and defoliation of the Brazilian weed, Euphorbia heterophylla, commonly found growing among soyabean crops. Only

Fitness Cost of Imazamox Resistance in Wild Poinsettia (Euphorbia heterophylla L.) [PDF]

Agronomy, 2020
Wild poinsettia (Euphorbia heterophylla L.) is a difficult-to-control weed in soybean production in Brazil that has developed resistance to herbicides, including acetolactate synthase inhibitors. We investigated the potential fitness cost associated to the Ser-653-Asn mutation that confers imazamox resistance in this weed.

PHYTOCHEMICAL STUDY OF EUPHORBIA HETEROPHYLLA L. CULTIVATED IN EGYPT [PDF]

Bulletin of Pharmaceutical Sciences. Assiut, 1990
A phytochemical study of Euphorbia heterophylla L. cultivated in Egypt is presented. b-amyrin, b-sitosterol taraxasterol acetate, b-sitosterol glucoside and hydrocarbon with ketonic group were isolated from pet. ether extract of the herb. While lupeol acetate, teraxasterol, b-sitosterol and b-sitosterol glucoside were isolated from ether extract of the

Sixty Years of Sugarcane Monoculture Alters Carbon Preservation in Large Soil Macroaggregates in Tropical Soil

Land Degradation &Development, Volume 36, Issue 12, Page 4056-4067, 30 July 2025.
ABSTRACT Frequent and intensive tillage in conventional agriculture disrupts soil aggregates, engendering significant depletion of soil organic carbon (SOC) stocks. Long‐term studies are essential for assessing the impact of sustainable practices on aggregate dynamics and carbon sequestration in sugarcane monocropping in tropical ecosystems.

Aminoisothiazolamides, a new class of potent inhibitors of lysyl‐tRNA synthetase

Pest Management Science, Volume 81, Issue 7, Page 3956-3983, July 2025.
The present work covers a series of novel herbicidal lead structures that possess an aminoisothiazolamide scaffold as a structural key feature. Lysyl‐tRNA synthetase 1 (KRS1) was identified as the biochemical mode‐of‐action. Based on optimized and tailored synthetic approaches, a broader SAR study was carried out delivering some lead structures that ...
