“…On the other hand, other species are considered weeds but because of their toxicity. In addition to the risk to human health, the poisoning caused by the ingestion of toxic plants is one of the main causes of mortality of livestock animals and causes great economic losses (Gallo 1979, Acamovic et al 2004, Campos et al 2016.…”

Currently, in Argentina 368 species of true ferns (i.e. Polypodiopsida class) are distributed throughout the country, however, only four of them have been mentioned until now as weeds and ruderal species. The goal of this work was to generate an update of weedy ferns from Argentina, including morphology, distribution, and type of weed according to their impact on natural habitats and/or human activities. All Argentinian fern species were analyzed based on references, herbarium specimens, and field trips. As a result of our study 25 species were recorded from Argentina and classified as segetal, ecological, or aquatic weeds, and ruderal and/or toxic species. Current taxonomic identity, diagnostic characters, origins, habitats, geographical distribution, common names, and impact and potential risks were indicated by species. In addition, we provide a dichotomous key to species, presence of these species in southern South American countries, as well as and photographs in natural habitat. This work represents the first review on native and exotic ferns from Argentina that cause an impact on human activities or disturbe native habitats. The results provide information for the development of weed management tools and priority areas to implement them.

“…Os efeitos adversos associados ao uso de fitoterápicos e plantas medicinais ocorrem comumente, mas no Brasil a notificação dos eventos toxicológicos não é obrigatória, o que favorece a subnotificação (CAMPOS et al, 2016). A hipersensibilidade é um dos efeitos colaterais mais comum causado pelo uso de plantas medicinais (PERHARIC et al, 1993).…”

The present work is a contribution to the advancement of the scientific knowledge of vegetal species of the Amazon and training of professionals in the area of vegetal and related sciences in the use of alternative methods and techniques more coherent with the context of the socioeconomic and environmental reality of the region. This work aimed to evaluate the effect of extracts prepared from bioprocessed remaining (BR), seeds of fruit of Myrciaria dubia (caçari) from the northern Amazon, applied to biological assay with Lycopersicon lycopersicum (tomato) seeds. To obtain and classify the degree of phytotoxicity were utilized samples of control and different aqueous extracts, with and without treatment, assessing their physical and chemical quality via pH analysis, electrical conductivity and total of dissolved salts. Thereafter, monitoring of bioassay was held for five days in closed glass plate, with samples incubation at 25 ± 1°C in a dark environment. It was obtained preliminary knowledge about four extracts prepared from T1 and T2 in proportion to 1:10 and 1:100. The methodological process applied allowed the quick examination, up to 120 h, of the effect of the extracts on seed germination and root growth of tomato. Of the four extracts evaluated, those who were previously treated T2D1 and T2D2, regardless of the applied concentration, showed no phytotoxicity to the plant tested and classified according to Germination Index (GI) obtained, 90.2 and 96.6%. The results show an important information about the influence of treatment of the bioprocessed compounds on their chemical and physicochemical characteristics, which can alter their effects on the development of other plants. Therefore, there is possibility of availability of finished products and raw materials from the M. dubia seeds, since previously sterilized.
