Ageratum conyzoides L. (Asteraceae) is an invasive aromatic herb with immense therapeutic importance. The herb is distributed in tropical and subtropical regions. A. conyzoides has imparted numerous ethnomedicinal uses because it has been used to cure various ailments that include leprosy, skin disorders, sleeping sickness, rheumatism, headaches, dyspnea, toothache, pneumonia and many more. A number of phytoconstituents have been scrutinized such as alkaloids, flavonoids, terpenes, chromenes, and sterols from almost every part of this plant. These phytoconstituents have shown diverse pharmacological properties including antimicrobial, anti-inflammatory, analgesic, antioxidant, anticancer, antiprotozoal, antidiabetic, spasmolytic, allelopathy, and many more. The plant A. conyzoides has provided a platform for doing pharmaceutical and toxicological research in order to isolate some promising active compounds and authenticate their safety in clinical uses. A. conyzoides provides principal information for advanced studies in the field of pharmaceutical industries and agriculture. Present review article describes the cytogenetics, ethnobotany, phytochemistry, pharmacology, and toxicological aspects of A. conyzoides.

L., an invasive plant originating from South America, is characterized by rapid growth and strong ecological adaptability, posing a threat to China's ecosystems, agricultural industry, and biodiversity. In this study, we optimized the MaxEnt model using the ENMeval package and constructed an ensemble model using the Biomod2 package based on global geospatial distribution data of and considering climate, soil, and topography factors.

L. is native to Tropical America, and it has naturalized in many other tropical, subtropical, and temperate countries in South America, Central and Southern Africa, South and East Asia, Eastern Austria, and Europe. The population of the species has increased dramatically as an invasive alien species, and it causes significant problems in agriculture and natural ecosystems.

Papaya leaf curl China virus (PaLCuCNV) is a damaging plant pathogen causing substantial losses to crop. The complete genomes of three PaLCuCNV isolates from Ageratum conyzoides were obtained and combined with the 68 reference isolates in GenBank for comprehensive genetic diversity analyses using specialized computational tools. Sequence alignment revealed nucleotide sequence similarity ranging from 85.

This work employed a green approach utilizing natural deep eutectic solvent (NADES)-assisted hydrodistillation for EO extraction from the aerial part of Ageratum conyzoides. Out of seven deep eutectic combinations used, glycerol-lactic acid (GLY:LA) (1 : 1) mixture significantly enhanced the yield from 0.78 mg/g (water as extraction media) to 1.

To examine the effects of the recent invasion on plant community and diversity in invaded habitats, the composition, density, species richness, diversity indices, and evenness index of the soil seed bank community of two different habitats (wasteland and cultivated land) in Yunnan Province, China, were analyzed through field sampling and greenhouse germination tests. A total of 28 species of plants belonging to 15 families and 28 genera, all annual herbs, were found in the soil seed bank. Seed densities and species number in the seed bank tended to be greater in April than in October; cultivated land also featured higher seed densities and species numbers compared to wasteland.
