Potentialisation de l’efficacité d’un stimulateur de défense par un biostimulant contre le mildiou de la vigne

2022

L’induction de résistance des cultures aux maladies par des Stimulateurs de Défenses desPlantes (SDP) est l’une des stratégies envisagées pour réduire l'utilisation des pesticides de synthèse.Cependant, la variabilité de son efficacité au champ freine son développement. L’une des raisons estque, contrairement aux fongicides qui agissent directement sur les agents pathogènes, les SDP sollicitentl'immunité de la plante, dont la performance peut dépendre de son état physiologique. Outre les SDP,d'autres produits utilisés en agriculture, les biostimulants (BS), sont décrits pour améliorer certainesfonctions de la plante. Dans ce contexte, l'objectif de ce travail était de vérifier sur vigne si …

An ethoxylated surfactant enhances the penetration of the sulfated laminarin through leaf cuticle and stomata, leading to increased induced resistanc…

2016

International audience; Some β-1,3-glucans and particularly sulfated laminarin (PS3) are known as resistance inducers (RIs) in grapevine against the downy mildew. However, their efficacy in vineyard is still often too low, which might be caused by a limited penetration through the leaf cuticle following spray application. We used (14) C-sucrose uptake experiments with grapevine leaves in order to select a surfactant as saccharide penetration enhancer. Our results showed that though sucrose foliar uptake was low, it was strongly enhanced by Dehscofix CO125 (DE), a highly ethoxylated surfactant. Fluorescent saccharides were then produced and laser scanning microscopy was used to analyze their…

Le champignon mycorhizien Funneliformis mosseae comme agent de biocontrôle de la septoriose du blé

2022

International audience; La septoriose, maladie causée par le champignon hémibiotrophe Zymoseptoria tritici, est l’une des maladies les plus dommageables pour la culture du blé. Dans un contexte de transition agroécologique, le développement des stratégies de lutte respectueuses de la santé humaine et de l’environnement est une priorité. La colonisation racinaire des plantes par les champignons mycorhiziens à arbuscules (CMA) est connue pour induire la MIR (Mycorrhiza Induced Resistance), correspondant à un état de résistance de la plante à divers bio-agresseurs. Nous avons ainsi testé l’efficacité du CMA Funneliformis mosseae à protéger le blé contre la septoriose dans le cadre du projet Bi…

In situ Phenotyping of Grapevine Root System Architecture by 2D or 3D Imaging: Advantages and Limits of Three Cultivation Methods

2021

International audience; The root system plays an essential role in the development and physiology of the plant, as well as in its response to various stresses. However, it is often insufficiently studied, mainly because it is difficult to visualize. For grapevine, a plant of major economic interest, there is a growing need to study the root system, in particular to assess its resistance to biotic and abiotic stresses, understand the decline that may affect it, and identify new ecofriendly production systems. In this context, we have evaluated and compared three distinct growing methods (hydroponics, plane, and cylindric rhizotrons) in order to describe relevant architectural root traits of …

Les biostimulants ont-ils un impact sur la résistance induite par des éliciteurs contre le mildiou de la vigne ?

2017

SPEINRAUBIPM DOCT; La culture de la vigne constitue un intérêt économique majeur, mais la plupart des cépages sont sensibles aux maladies cryptogamiques telles que le mildiou. Protéger les vignobles contre ces maladies requiert souvent des fongicides de synthèse dont certains posent des problèmes environnementaux et sanitaires. Une stratégie potentielle serait d’utiliser des éliciteurs, molécules capables d’activer les réactions de défenses et d’établir un état de résistance face à une future attaque d’agents pathogènes. Cette stratégie est efficace sur des vignes cultivées en serres, mais reste non maîtrisée en conditions extérieures. Notre objectif est donc d’identifier des solutions susc…

Biostimulation of grapevine and wheat : mode of action and possible agronomic uses

2015

SPE IPM UBSPEIPMUB; Downy mildew, caused by Plasmopara viticola, is one of the most important grape pathogen in Europe and North America. Although the control is traditionally performed with fungicides, the appearance of resistant pathogen populations and the possible adverse effects on human and environment health are spurring the search for alternative means. In the present investigation, two protein hydrolysates of soybean (soy) and casein (cas) origin were successfully tested against P. viticola. On Vitis vinifera cv. Marselan plants, the application of soy and cas reduced the infected leaf surface by 76 and 63%, as compared to the untreated control, respectively. Since both hydrolysate…

A new tool for assessment of biostimulants effects on grapevine

2018

National audience; Despite an increasing interest for the use of biostimulants (BS) in agriculture, methods allowing a precise description of their effects on plants remain rather limited. In the IRIS+ FUI project, two major and highly different worldwide crops, wheat (annual, monocotyledon) and grapevine (perennial, broadleaf) were chosen to deepen our knowledge of such compounds and explore their potential additional interest. One objective was to develop a tool adapted to the screening and study of the impact of a series of BS on the development and physiology of these crops in controlled conditions. We managed to develop such a tool adapted to grapevine herbaceous cuttings. It allows a …

Impact of biostimulants on the resistance induction level of grapevine to downy mildew by elicitors

2018

The protection of vineyards against cryptogamic diseases such as downy mildew is mainly ensured by synthetic fungicides, which cause serious environmental and health problems. The induction of resistance by elicitors could allow to reduce their use. However, even if their efficacy is demonstrated in greenhouse conditions, it remains quite variable in field conditions. Indeed, the efficacy of an elicitor depends on the plant’s ability to respond, or more generally, on the latter’s physiological status. In this context, part of the FUI project IRIS+, the aim of this present work is to evaluate whether biostimulants, through their effect on the plant’s physiology, would be able to increase the…
