“…Despite the pharmacological potential, B. pilosa is also known as a noxious invasive weed species. The species is native to tropical America and has naturized in over 60 countries of tropical, subtropical, and warm temperate regions in Europe, Africa, Asia, Australia, and North and South America [1][2][3]. Many of the invasive plant species potentially threaten the native flora and fauna in the introduced ranges [16][17][18].…”

“…Many of the invasive plant species potentially threaten the native flora and fauna in the introduced ranges [16][17][18]. B. pilosa has infested a wide range of habitats such as grasslands, forest margins, secondary forests, wetlands, streamlines, coastal areas, roadsides, railway sides, disturbed lands, pasture, plantations, and agriculture fields [1,2,[19][20][21].

“…The ecosystems of these islands are very vulnerable to alien species [23,24]. B. pilosa is listed as a noxious agricultural and environmental weed in more than 40 countries [1,2,[19][20][21]. According to the accumulated publications, the species is highly invasive and potentially causes serious negative impacts on natural ecosystems and agricultural crop production.…”

Bidens pilosa L. is native to tropical America and has widely naturized from tropical to warm temperate regions in Europe, Africa, Asia, Australia, and North and South America. The species has infested a wide range of habitats such as grasslands, forests, wetlands, streamlines, coastal areas, pasture, plantations, agricultural fields, roadsides, and railway sides and has become a noxious invasive weed species. B. pilosa forms thick monospecific stands, quickly expands, and threatens the indigenous plant species and crop production. It is also involved in pathogen transmission as a vector. The species was reported to have (1) a high growth ability, producing several generations in a year; (2) a high achene production rate; (3) different biotypes of cypselae, differently germinating given the time and condition; (4) a high adaptative ability to various environmental conditions; (5) an ability to alter the microbial community, including mutualism with arbuscular mycorrhizal fungi; and (6) defense functions against natural enemies and allelopathy. The species produces several potential allelochemicals such as palmitic acid, p-coumaric acid, caffeic acid, ferulic acid, p-hydroxybenzoic acid, vanillic acid, salycilic acid, quercetin, α-pinene, and limonene and compounds involved in the defense functions such as 1-phenylhepta-1,3,5-trine, 5-phenyl-2-(1-propynyl)-thiophene, 5-actoxy-2-phenylethinyl-thiophene, and icthyothereol acetate. These characteristics of B. pilosa may contribute to the naturalization and invasiveness of the species in the introduced ranges. This is the first review article focusing on the invasive mechanisms of the species.

To develop models capable of predicting the emergence of hairy beggarticks and assist integrated management, it is fundamental to have knowledge of the environmental factors that influence the germination of the species. The objective of this study was to estimate temperature and water potential cardinals for hairy beggarticks germination, the longevity of its seed bank, and to develop a model of its emergence in the field. Experiments were carried out in the laboratory to determine the temperature and water potential base for seed germination. Eight different temperatures (10.0, 15.0, 20.0, 25.0, 30.0, 35.0, 40.0, and 45.0°C), and 10 different water potentials (0, -0.05, -0.1, -0.2, -0.4, -0.6, -0.9, -1.2, -1.5, and − 2.0 MPa) were tested. The field experiments were conducted between 2014 and 2019 using three monitoring seedling emergences. To evaluate the longevity and persistence of the seed bank, a factorial experiment was conducted with three burial depths (0, 3, and 6 cm) and five seed retrieval moments (0, 1, 4, 10, and 16 months). Base, optimal, and maximum temperatures for hairy beggarticks germination are 10.4°C, 24.7°C, and 41.8°C, respectively. The base water potential for the emergence of hairy beggarticks is -0.85 MPa. The thermal and hydrothermal time models are adequate to predict the emergence of hairy beggarticks in different soybean sowing dates. The species has a transient seed bank, however, the greater the seed burial depth, the greater the longevity of the soil seed bank.
