The phyllosphere is colonized by complex microbial communities, which are adapted to the harsh habitat. Although role and ecology of nonpathogenic microorganisms only partially understood, leaf microbiota could have a beneficial in plant growth health. Pesticides biocontrol agents frequently applied grapevines, but impact on nontarget has been marginally considered. In this study, we investigated effect chemical fungicide (penconazole) biological control agent (Lysobacter capsici AZ78)...
To investigate low molecular weight compounds produced in vitro by Lysobacter capsici AZ78 and their toxic activity against sporangia of plant pathogenic oomycetes.Assays carried out showed that L. drastically inhibits the growth oomycetes. Accordingly, preventive application culture filtrates on grapevine tomato plants reduced infections, respectively, caused Plasmopara (Pl.) viticola Phytophthora infestans. The subsequent chemical analysis spectroscopic (essentially 1D 2D (1)H NMR (13)C...
The reduction of pesticide treatments is paramount importance for the sustainability viticulture, and it can be achieved through a combination strategies, including cultivation vines ( Vitis vinifera ) that are resistant or tolerant to diseases such as downy mildew (DM). In many crops, knock-out Downy Mildew Resistant 6 DMR6 proved successful in controlling DM-resistance, but effect mutations genes not yet known grapevine. Today, gene editing serves crop improvement with small specific while...
Abstract This case explores grapevine downy mildew caused by Plasmopara viticola examining its life cycle and impact on viticulture. It also briefly discusses the challenges importance of breeding resistant varieties. Particular attention has been given to use chemical plant protection products their limitations. Finally, this work illustrates potential development bioproducts as an alternative input for management mildew. Information © The Authors 2025
Plants host a complex microbiota inside or outside their tissues, and phyllosphere microorganisms can be influenced by environmental, nutritional agronomic factors. Rare sugars are defined as monosaccharides with limited availability in nature they metabolised only few certain microbial taxa. Among rare sugars, tagatose (TAG) is low-calories sweetener that stimulates inhibits beneficial pathogenic bacteria the human gut microbiota, respectively. Based on this differential effect...
The ability of sage (Salvia officinalis) extract to control grapevine downy mildew under greenhouse and field conditions was tested. persistence rainfastness were also investigated. Sage provided a high level sustained disease in artificially inoculated, potted conditions. However, even small amounts simulated rainfall (10 mm) significantly reduced efficacy extract. In experiment 2006, 94% reduction incidence 63% area the progress curve for severity on berries leaves, respectively, reaching...
Downy mildew, caused by P lasmopara viticola , is one of the most destructive diseases grapevine and controlled with intense application chemical fungicides. Treatment T richoderma harzianum T39 (T39) or benzothiadiazole‐7‐carbothioic acid S ‐methyl ester ( BTH ) has been previously shown to activate resistance downy mildew reduce disease symptoms in Pinot noir cultivar. However, enhancement plant can be affected several factors, including genotype. In order further extend use inducers...
Abstract Plasmopara viticola is one of the most important pathogens infecting Vitis vinifera plants. The interactions among P. and both susceptible resistant grapevine plants have been extensively characterised, at transcriptomic, proteomic metabolomic levels. However, involvement ionome in response against pathogen has completely neglected so far. Therefore, this study was aimed investigating possible role leaf ionomic modulation during compatible incompatible between In cultivars, a...
Powdery mildew caused by Erysiphe necator is one of the most important grapevine diseases in several viticulture areas, and high fungicide input required to control it. However, numerous synthetic chemical pesticides are under scrutiny due concerns about their impact on human health environment. Biopesticides, such as biogenic elicitors, a promising alternative fungicides. Although studies have reported effective elicitors against diseases, efficacy field conditions has not been investigated...
Plant extracts might provide sustainable alternatives to copper fungicides, which are still widely used despite their unfavourable ecotoxicological profile. Larch bark extract and its constituents, larixyl acetate larixol, have been shown be effective against grapevine downy mildew (Plasmopara viticola) under semi-controlled conditions. The aim of this study was reduce the gap between innovation registration a marketable product, namely develop scalable extraction processes evaluate optimise...
Downy mildew, caused by Plasmopara viticola, is a highly significant grapevine disease causing severe yield losses and affecting wine quality. Disease control mainly relies on use of copper synthetic fungicides. Today there growing interest in developing microbial biopesticides for downy mildew integrated organic viticulture. Here, the bacterial biocontrol agent Lysobacter capsici AZ78 (AZ78) was tested following holistic approach including planta efficacy test (large-scale trial) combined...
Survival in the phyllosphere is a critical feature for biofungicides based on non-spore forming bacteria. Moreover, knowledge of their persistence plants important to design effective formulations and application techniques. With this scope, aim work was develop specific method monitor fate environment Lysobacter capsici AZ78, biocontrol agent Plasmopara viticola, evaluate contribution formulation its grapevine leaves. A strain-specific primer pair derived from REP-PCR fingerprinting used...
Powdery mildew is a constant threat to cucumber production in soilless systems requiring the intensive use of chemical fungicides limit yield losses. However, toxicity risks for growers and food safety issues linked fungicide residues represent major concern crops with frequent extended harvest period, like cucumber, create an urgent need eco-friendly alternatives. The objective this study was assess effectiveness foliar root applications rare sugar tagatose, against naturally occurring...
Abstract Crop improvement by means of traditional or molecular breeding is a key strategy to accomplish the European Green Deal target reducing pesticides 50% 2030. Regarding viticulture, this exacerbated massive use chemicals control pathogen infections. Black rot an emergent disease caused ascomycete Phyllosticta ampelicida , and its destructiveness alarming vine growers. Implementing improving effective phenotyping strategies are fundamental preliminary steps breed resistant varieties...
The substitution of synthetic chemical pesticides has become a priority in agriculture and the induction plant resistance by protein hydrolysates may offer sustainable alternative.The source, method degree hydrolysis, as well amino acid peptide composition affect efficacy protecting plants against pathogens.The aim this work was to clarify effect enzymatic hydrolysis on different sources (soybean, rapeseed guar meal), terms powdery mildew courgette (caused Podosphaera xanthii).The were...
Plasmopara viticola is a destructive oomycete that affects grapevines, causing significant economic losses worldwide. This study highlights how the plant Glechoma hederacea might be at basis for development of biofungicides to control P. viticola. The aqueous extract obtained from G. aerial parts showed strong inhibition activity against viticola, comparable copper hydroxide. bioguided purification by chromatographic techniques led isolation six pure metabolites, identified as aromatic...
Background and Aims. Grapevine is susceptible to several diseases requires a large use of fungicides. Sustainable alternatives must be safe for humans the environment also should not interfere with fermentation. The aim this study was implement rare sugar, tagatose, against powdery mildew downy assess possible side effects on Saccharomyces cerevisiae Methods Results. Tagatose evaluated suppression under controlled field conditions its impact S. fermentation synthetic grape musts. applied at...
In the defense against downy mildew, copper is still widely used, particularly in organic management. At any rate, specific investigations are needed to significantly reduce use of and minimize its environmental impact. This study, conducted several farms Friuli-Venezia Giulia (Northeast Italy), aimed evaluate concentration on leaves various climatic conditions, order create an important database for development a rapid control system through image analysis.
