Abstract It is imperative to enhance crop yield to meet the demands of a burgeoning global population while simultaneously safeguarding the environment from adverse impacts, which is one of the dominant challenges confronting humanity in this phase of global climate change. To overcome this problem and reduce dependency on chemical fertilizer, scientists now view the implementation of biostimulant strategies as a cost-effective and environmentally friendly approach to achieving sustainable agriculture. Plant extracts are rich in bioactive phytocompounds, which can enhance plant resistance to disease, pest, and abiotic stresses (e.g., drought, salinity, and extreme temperature), and promote… More >

Abstract The objective to this work was to evaluate the enzymatic activity in the culture of Solanum lycopersicum L. infected with Fusarium oxysporum after the combined application of Beauveria bassiana and plant extracts. Solanum lycopersicum plantlets were transplanted 15 days after the emergency. Five days after transplanting, Beauveria bassiana spores were applied at a concentration of 1 × 10⁷ spores mL⁻¹ onto soil (along with A. indica (N) and P. auritum (H) leaf extracts) where S. lycopersicum plants were planted. Eight days after transplanting, spores of F. oxysporum strain were applied at a concentration of 1 × 10⁶ spores mL⁻¹ to soil where S. lycopersicum plants were growing.… More >

Abstract The beet armyworm (BAW), Spodoptera exigua (Lepidoptera: Noctuidae) is a highly destructive pest of vegetables and field crops. Management of beet armyworm primarily relies on synthetic pesticides, which is threatening the beneficial community and environment. Most importantly, the BAW developed resistance to synthetic pesticides with making it difficult to manage. Therefore, alternative and environment-friendly pest management tactics are urgently required. The use of pesticidal plant extracts provides an effective way for a sustainable pest management program. To evaluate the use of pesticidal plant extracts against BAW, we selected six plant species (Lantana camara, Aloe vera, Azadirachta indica, Cymbopogon citratus, Nicotiana tabacum , and… More >

Abstract Nanoparticles (NPs) have already been widely used in catalysis, antibacterial and coating fields. Compared with the traditional toxic and harmful reducing reagents, green synthesis of NPs by using plant extracts is not only environmental-friendly and cost-effective but also conducive to the multi-level and efficient utilization of wild plant resources. In this study, the aqueous extracts from Sorbus pohuashanensis (SP) and Aronia melanocarpa (AM) fruits were used as the reducing and protective reagents for synthesizing Au/AgNPs, with the characteristics of originality operation and high repeatability. The SP/AM fruit extracts functionalized Au/AgNPs were characterized by UV-vis spectroscopy (UV-vis), transmission… More > Graphic Abstract

Abstract Moringa oleifera is a miracle plant rich in nutrients, antioxidants, and antibiotic properties. Present study was designed to evaluate various biochemical attributes of leaves and flowers of M. oleifera. Plant parts (leaves, flowers) of M. oleifera, collected from different roadsides of Multan district, Punjab, Pakistan, were used as experimental material. Result indicates that alkaloids, saponin, carbohydrates, fats, and protein had a high value in the aqueous extract of both leaves and flowers of M. oleifera. Whereas phenol content was high in methanolic leaves extract and the phenol contents were high in aqueous extract of flowers. The extract yield of… More >

Abstract The aim of this work was to develop an active biopolymer based on chitosan by incorporating natural antioxidants. Five essential oils (ginger, rosemary, sage, tea tree and thyme) and six hydro-alcoholic extracts (from ginger, green and black tea, kenaf leaves, rosemary and sage plants) were tested. Migration assays were carried out to evaluate the films' activity, and total phenolic content and antioxidant activity were monitored in the simulant during storage. Interaction between natural compounds and polymeric matrix was evaluated by FTIR spectroscopy. The diffusion of the phenolic compounds was not detected in the films incorporated More >

Abstract The polyphagous plant pathogen Botrytis cinerea has the ability of growing fast under several conditions, and producing grey moulds in different plant tissues. Because of its adaptive plasticity, resistant strains have made difficult their chemical control. Therefore, new strategies of management and the use of natural compounds could be important control alternatives. The aim of this work was to study the potential value of four Argentine native plant extracts and some of its phenolic compounds as biodrugs on B. cinerea. Aqueous plant extracts of Larrea divaricata, Prosopis strombulifera, Tessaria absinthioides and Schinus molle var. areira, were used. The More >

Abstract Plants contain numerous constituents and are valuable sources of new biologically active molecules. Avocado (Persea americana Mill.) is cultivated and used as food in most tropical and subtropical countries. Its high nutritional value and biological activities, as antioxidant, antimicrobial and analgesic properties, have been thoroughly investigated. Interest in plant extracts with antimicrobial properties has increased as a result of the indiscriminate use of antibiotics, leading to the emergence of resistant bacterial strains. Among bacterial species with clinical importance to multiple hosts, Streptococcus agalactiae is outstanding, as it can cause infections especially in humans, fish and cattle. The… More >

Abstract Species of the genus Psychotria are used for multiple purposes in Brazilian folk medicine, either as water infusions, baths or poultices. This study was aimed to evaluate the genotoxic and antiproliferative effects of infusions of Psychotria brachypoda and P. birotula on the Allium cepa test. Exposure to distilled water was used as a negative control, while exposure to glyphosate was used as a positive control. The interaction of extracts (as a post-treatment) with the effects of glyphosate was also studied. Results showed that glyphosate and the extracts of both P. brachypoda and P. birotula reduced the mitotic index as compared… More >

Abstract We evaluated the in vitro antifungal activity of extracts of peruvian peppertree (Shinu smolle), cherimoya (Annona cherimola), cinnamon (Cinnamomum zeylanicum) and tobacco (Nicotiana glauca) on the mycelial growth and sporulation of Fusarium oxysporum, Fusarium culmorum and Fusarium solani. The research was conducted at the Universidad Autónoma de Aguascalientes (UAA) and the Universidad Autónoma Agraria Antonio Narro (UAAAN). The species of Fusarium were previously identified in the UAA Laboratory of Parasitology. The extracts were obtained in the laboratory of Toxicology of the UAAAN. The methodology of poisoned culture medium was used to determine the (1) inhibition of mycelial growth, (2) average effective dose… More >
