“…However, there are no studies describing the movement of peptides applied by endotherapy along the vascular system, so it should be studied in detail in the future. Additionally, endotherapy has other advantages compared to other application methods, since it allows precise administration and dosage of the active ingredient and avoids pesticide drift in agriculture applications, which result in a lower impact to the environment (Braekman et al 2009 ; Ferreira et al 2022 ; Grandi et al 2023 ).…”

Key message New defense elicitor peptides have been identified which control Xylella fastidiosa infections in almond. Abstract Xylella fastidiosa is a plant pathogenic bacterium that has been introduced in the European Union (EU), threatening the agricultural economy of relevant Mediterranean crops such as almond (Prunus dulcis). Plant defense elicitor peptides would be promising to manage diseases such as almond leaf scorch, but their effect on the host has not been fully studied. In this work, the response of almond plants to the defense elicitor peptide flg22-NH2 was studied in depth using RNA-seq, confirming the activation of the salicylic acid and abscisic acid pathways. Marker genes related to the response triggered by flg22-NH2 were used to study the effect of the application strategy of the peptide on almond plants and to depict its time course. The application of flg22-NH2 by endotherapy triggered the highest number of upregulated genes, especially at 6 h after the treatment. A library of peptides that includes BP100-flg15, HpaG23, FV7, RIJK2, PIP-1, Pep13, BP16-Pep13, flg15-BP100 and BP16 triggered a stronger defense response in almond plants than flg22-NH2. The best candidate, FV7, when applied by endotherapy on almond plants inoculated with X. fastidiosa, significantly reduced levels of the pathogen and decreased disease symptoms. Therefore, these novel plant defense elicitors are suitable candidates to manage diseases caused by X. fastidiosa, in particular almond leaf scorch.

“…Recent studies in nanotechnology present more possibilities for endotherapy as products based on nanoparticles are strong candidates to be more potent agents than active ingredients currently used as antibiotics to decrease bacteria in plants [49,75]. Other types of bioinsecticides and bactericides for applications in sustainable agriculture from an ecotoxicological perspective were used, such as neem oil (azadirachtin) [102,117] and garlic oil (allicin) [118]. A study was conducted using aquatic and terrestrial microcosms and proved that using azadirachtin for endotherapy probably does not pose a significant health risk to aquatic or terrestrial invertebrates when leaves treated with insecticide fall from trees.…”

“…Chromatographic analyses use the physical-chemical characteristics of the molecules, such as polarity and volatility, among others, usually after the extraction of the analytes. Fungicides on leaves and apple fruit used gas chromatography coupled to mass spectrometry (GC-MS) and liquid chromatography coupled to mass spectrometry (LC-MS) [81]; fungicides and insecticides in the coconut stem used liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) [58,[99][100][101][102][103]156]; fungicide in roots and trunk was evaluated by GC-MS [106]; uricosuric agent and anti-inflammatory compounds in leaves, roots, fruit peel, fruit juice samples used LC-MS/MS [59]; bioactive constituents present in plants using GC-MS and HPLC [90]; insecticide in avocados was analyzed by GC and LC, although the authors did not mention the type of detector used [94]. Enzyme-linked immunosorbent assay (ELISA) was used for quantitative and qualitative analysis: insecticide in avocado leaf tissue [9,94]; insecticide in Wiliwili tree leaves [130]; insecticides in avocado leaf and fruit [93]; antibiotics in petiole, midrib, bud or root tissue all used double antibody sandwich-enzyme linked immunosorbent assays (DAS-ELISA) [84].…”

Vegetative endotherapy has shown satisfactory results in replacing conventional techniques for crop production material applications, such as spraying or via soil, in trees of perennial species. This review presents an overview of concepts and classifications for existing injection methods and covers applications from articles published in the last eighteen years on endotherapeutic techniques. An Excel interactive dashboard as supplementary material with data segmentation and filters to facilitate understanding of the data is provided. The indicators more relevant to researchers and producers, including the tree species evaluated, which were deciduous trees (24%), conifers (11%), ornamental (11%), and fruit trees (54%), are outlined. The most used products were insecticides, fungicides, and antibiotics, which are discussed. Pressurized and nonpressurized technologies were evaluated based on trunk opening, interface, and injection methods. And finally, an approach to good practices in precision agriculture is also discussed.
