Abstract:

The increasing resistance to synthetic fungicides and the demand for sustainable agricultural practices have bolstered interest in essential oils (EOs) as antifungal alternatives. However, the lack of an integrated view regarding the evolution and conceptual foci of this field limits strategic advancement. This study maps global research on the mechanisms of action of EOs against phytopathogenic fungi, aiming to guide future investigations towards the development of safe biopesticides. A systematic and bibliometric analysis of 73 documents (2005–2025) from the Web of Science and Scopus databases was conducted. The approach integrated Lotka’s, Bradford’s, and Zipf’s laws, alongside conceptual mapping across four central dimensions: scientific growth, authorship structure, editorial organisation, and conceptual pillars. The results indicate that the field is in a phase of accelerated scientific emergence, characterised by a 14.5% annual growth rate and high citation impact per document. Authorship analysis revealed a strong concentration of specialists, indicating a high degree of specialisation; similarly, the editorial structure proved consolidated within specific journals. Although the term “antifungal activity” predominates, emerging strategic niches were identified, particularly those related to the generation of reactive oxygen species (ROS) and biophysical interactions with the cell membrane. International collaboration was observed to be the primary predictor of scientific impact. It is concluded that essential oil (EO) research is at an inflection point, requiring a transition from predominantly phenotypic approaches to in-depth molecular and mechanistic investigations. Diversifying collaboration networks and investing in emerging conceptual niches are essential to consolidating EOs as viable tools for plant protection.

Abstract:

Potato and coffee crops grapple with pronounced challenges posed by pests, notably the Andean potato weevils (Premnotrypes spp.) and the coffee berry borer (Hypothenemus hampei). These pests inflict significant economic repercussions on both smallholder and commercial farmers by disrupting essential food supply chains. This review delves into the insecticidal potentials of botanical resources against these pests. Notably, extracts and essential oils (EOs) from native flora or commercially available in each affected country have compelled efficacy against Premnotrypes vorax, P. latithorax and Hypothenemus hampei, such as Schinus molle L. and Schinus terebinthifolia Raddi, respectively. Through rigorous laboratory tests, on-site evaluations, and cost-effectiveness assessments, there emerges a strong advocacy for these botanical solutions. They present not only a sustainable countermeasure to these pests but also a greener alternative to conventional pesticides, thereby potentially reducing the environmental degradation and health concerns synonymous with chemical pesticides. The shift towards natural pesticides, especially those derived from plants like S. molle and S. terebinthifolia, is not only environmentally strategic but also economically prudent, aligning with both market trends and long-term sustainability goals.

Abstract:

The results of studies of influence of raspberry plant varieties and new organic fertilizers on the abundance and species composition of the micromycetes in rhizospheric soil in conditions of organic production are presented. The mycobiota of Joan J and Himbo-Top raspberry varieties during plant ontogeny was analyzed and the species composition of phytopathogenic micromycetes, which are presented in the rhizospheric plant soil, was defined. It was revealed that the following fungi species prevail in the population: Botrytis cinerea, Pers, Aspergillus niger, V. Tiegh, Alternaria alternata, (Fr.) Keissl, Fusarium sp. These fungi are producers of mycotoxins that can cause dangerous diseases in animals and humans. There is a stabilizing selection of microorganisms in the phase of separation of buds in inflorescences in the mycobiota of the rhizosphere of plants of raspberry varieties under the influence of the organic fertilizer VITERI with the addition of Basil essential oil.

Abstract:

In search for alternative ways of plant disease control, essential oils from aromatic and medicinal plants were studied for their antibacterial properties. In a preliminary evaluation, steam-distilled essential oils from oregano, sweet-flag, caraway, peppermint, common, fern leaf and willow-leaved yarrow field accessions were investigated against growth of phytopathogenic bacteria. The disc-diffusion method was used for the assessment of inhibitory effects of the essential oils. The antibacterial activity tests were conducted in vitro. Essential oil from oregano was found to have the strongest inhibitory effect against tested phytopathogenic bacteria. Less antibacterial effect was found with essential oils from caraway, peppermint, fern-leaf and willow-leaved yarrow,, while the oils from common yarrow and sweet-flag manifested no inhibition. Xanthomonas vesicatoria 67 was the most sensitive to essential oils tested. A weak antibacterial activity was found against some Pseudomonas spp. strains and Erwinia carotovora subsp. carotovora bacteria.
