“…Así mismo, el extracto de cola de caballo (Equisetum sp.) y canela (Cinnamomum zeylanicum) han sido utilizados para el control de varias especies de hongos fitopatógenos con resultados variables (Cruz et al 2013, Silva-Espinoza et al 2013, Radojević et al 2012, Rogozhin et al 2011. Investigaciones previas señalan que extractos de cola de caballo contienen una saponina tóxica para los hongos llamada Equisetonina y ácido silícico que favorecen el engrosamiento de las paredes celulares, lo que impide la penetración de los hongos (Velastegui & Niera 2014, Latorre et al 2001.…”

“…To screen for antifungal activity in vitro, we selected plants used in traditional medicine: greater celandine ( Chelidonium majus ), PE-Cm; elecampane ( Inula helertium ), PE-Ih; common horsetail ( Equisetum arvense ), PE-Eqi; sweet bay ( Laurus nobilis ), PE-Ln; green tea ( Camellia sinensis ), PE-Cs; touch-and-heal ( Hypericum perforatum ), PE-Hp; and a mixture of the three plants combined (elecampane, greater celandine, and common horsetail), PE-Pm. Initially, all plant raw material was collected manually [ 35 , 68 ].…”

We report the inhibitory effect of peptide extracts obtained from seven medicinal plants against a causative agent of late blight disease Phytophthora infestans. We find that all the extracts possess inhibitory activity toward the zoospores output, zoosporangium germination, and the development of P. infestans on potato disc tubers at different quantitative levels. Based on the biological effects detected, an extract of common horsetail (Equisetum arvense) biomass is recognized as the most effective and is selected for further structural analysis. We perform a combination of amino acid analysis and MALDI-TOF mass spectrometry, which reveal the presence of Asn/Asp- and Gln/Glu-rich short peptides with molecular masses in the range of 500–900 Da and not exceeding 1500 Da as the maximum. Analytical anion-exchange HPLC is successfully applied for separation of the peptide extract from common horsetail (E. arvense). We collect nine dominant components that are combined in two groups with differences in retention times. The N-terminal amino acid sequence of the prevalent compounds after analytical ion-exchange HPLC allows us to identify them as peptide fragments of functionally active proteins associated with photosynthesis, aquatic transport, and chitin binding. The anti-oomycete effects may be associated with the conversion of ribulose-1,5-bisphosphate carboxylase/oxygenase to produce a number of biologically active anionic peptides with possible regulatory functions. These data inform our knowledge regarding biologically active peptide fragments; they are the components of programmed or induced proteolysis of plant proteins and can realize secondary antimicrobial functions.

“…There are also studies on the antimicrobial properties of extracts from E. arvense [15,16] and other Equisetum spp. [10,[17][18][19], and Urtica spp. extracts [20][21][22][23][24].…”

Assessment of Conjugate Complexes of Chitosan and Urtica dioica or Equisetum arvense Extracts for the Control of Grapevine Trunk Pathogens

et al. 2021

In the work presented herein, we analyze the efficacy of three basic substances that comply with European Regulation (EC) No 1107/2009, namely chitosan, horsetail (Equisetum arvense L.) and nettle (Urtica dioica L.), for the control of grapevine trunk diseases (GTDs) in organic farming. The E. arvense and U. dioica aqueous extracts, prepared according to SANCO/12386/2013 and SANTE/11809/2016, have been studied by gas chromatography–mass spectrometry (GC-MS), identifying their main active constituents. The three basic substances, either alone or in combination (forming conjugate complexes), have been tested in vitro against eight Botryosphaeriaceae species, and in vivo, in grafted plants artificially inoculated with Neofusicoccum parvum and Diplodia seriata. A clear synergistic behavior between chitosan and the two plant extracts has been observed in the mycelial growth inhibition tests (resulting in EC90 values as low as 208 μg·mL−1 for some of the isolates), and statistically significant differences have been found in terms of vascular necroses lengths between treated and non-treated plants, providing further evidence of aforementioned synergism in the case of D. seriata. The reported data supports the possibility of extending the applications of these three basic substances in Viticulture beyond the treatment of mildew.
