An ambitious plan to anticipate the withdrawal of plant protection products, backed by the public authorities

Abstract

Faced with the likely withdrawal of commercial specialities from use in the short to medium term, france has decided to implement an ambitious action plan to anticipate and avoid withdrawal without alternative solutions. The French wine industry (CNIV and IFV) has been heavily involved in this action to define priorities. Faced with the risk of the withdrawal of multi-site fungicides (folpel, dithianon, copper) coupled with the probable reduction in single-site fungicide solutions, mildew and black rot have been identified as the priority uses. In addition, the use of flavescence dorée leafhoppers (a single authorised chemical family) was also identified as a use where action should be taken to manage this mycoplasma differently. Finally, herbicide use remains a priority in view of the recent restrictions on the use of glyphosate in France. At the end of 2023, an action plan was drawn up by the winegrowing sector to define the avenues to be explored to maintain innovative solutions and technical approaches to managing mildew and black rot. This action plan provides a 360° vision, from research to transfer and from knowledge acquisition to solution evaluation at plot and landscape level. The joint desire of the stakeholders (industry and public authorities) is to work on solutions for the short to medium term, but also for the longer term. For example, there are plans to increase our knowledge of the sexual cycle of these two fungal diseases in order to evaluate alternative control solutions based on monitoring the winter phase (prophylaxis). In addition, this action plan aims to ensure the sustainability of resistant varieties by monitoring plots and searching for new resistance genes. Finally, of course, the evaluation of alternative solutions (biosolutions or physical methods) will be worked on. The aim of all this work, which will receive financial support from the French ministry of agriculture, is to develop innovative techniques that will ultimately lead to a new technical and economic approach. The aim is to combine levers at plot and regional level. The projects submitted by the various players in the sector will be assessed by a scientific and technical committee co-chaired by INRAE and Acta. The entire withdrawal anticipation plan (Parsada) is scheduled to run for 3 years (2024-2026).

Un plan d’anticipation des retraits d’usage des produits phytosanitaires ambitieux porté par les pouvoirs publics

Face aux enjeux du retrait d’usage probable de spécialités commerciales à court ou moyen terme, la France a souhaité mettre en œuvre un plan d’action ambitieux d’anticipation pour éviter le retrait d’usage sans solutions alternatives. La filière viticole française (CNIV et IFV) s’est fortement impliquée dans cette action pour définir les priorités. Ainsi, face au risque de retrait d’usage des substances fongicides multisites (folpel, dithianon, cuivre) couplée à la réduction probable des solutions fongicides unisites, le mildiou et le black ont été identifiés comme les usages prioritaires. En complément, l’usage cicadelle de la flavescence dorée (une seule famille chimique autorisée) a également été identifiée comme un usage sur lesquels des actions devaient être entreprises en vue de gérer différemment ce mycoplasme. Enfin, l’usage herbicide reste une priorité au regard des récentes restrictions d’emploi du glyphosate en France. Fin 2023, un plan d’action a été élaboré par la filière viticole pour définir les pistes à explorer pour maintenir des solutions et des approches techniques innovantes pour la gestion du mildiou et du black. Ce plan d’action apporte une vision à 360° de la recherche au transfert et de l’acquisition de connaissance aux évaluations de solution à l’échelle de la parcelle et du paysage. La volonté conjointe des parties prenantes (filière et pouvoirs publics) est de travailler sur des solutions à court moyen terme mais aussi sur des perspectives à plus long terme. Ainsi, il est prévu de renforcer l’acquisition de connaissance sur le cycle sexué de ces deux maladies fongiques pour évaluer des solutions alternatives de lutte basé sur le contrôle de la phase hivernale (prophylaxie). En complément ce plan d’action ambitionne d’assurer la durabilité des variétés résistantes par le suivi des parcelles et la recherche de nouveaux gènes de résistance. Enfin, bien entendu l’évaluation de solutions alternatives (biosolutions ou méthodes physiques) seront travaillés. L’ensemble de ce travail, sera accompagné financièrement par le ministère de l’agriculture, a pour ambition de développer des travaux innovants pour s’inscrire à terme dans une nouvelle approche technique et économique. Il s’inscrit dans une volonté de coupler les leviers à l’échelle de la parcelle et du territoire. Les projets déposés par les différents acteurs de la filière seront évalués par un comité scientifique et technique co-présidé par l’INRAE et l’Acta. L’ensemble de ce plan d’anticipation des retraits (Parsada) est prévu pour une durée de 3 ans (2024-2026).

Un ambicioso plan para anticipar la retirada de productos fitosanitarios, respaldado por las autoridades públicas

Ante la probable retirada de las especialidades comerciales a corto o medio plazo, Francia ha decidido poner en marcha un ambicioso plan de acción para anticiparse y evitar la retirada sin soluciones alternativas. El sector vitivinícola francés (CNIV e IFV) ha participado intensamente en esta acción para definir las prioridades. Ante el riesgo de retirada de los fungicidas multisitio (folpel, ditianón, cobre) y la probable reducción de las soluciones fungicidas monositio, se han identificado como usos prioritarios el mildiu y la podredumbre negra. Además, el uso de saltahojas de la flavescencia dorada (una única familia química autorizada) también se identificó como un uso en el que se debería actuar para gestionar este micoplasma de forma diferente. Por último, el uso de herbicidas sigue siendo prioritario a la vista de las recientes restricciones impuestas al uso de glifosato en francia. A finales de 2023, el sector vitivinícola elaboró un plan de acción para definir las vías que deben explorarse para mantener soluciones innovadoras y enfoques técnicos para gestionar el mildiu y la podredumbre negra. Este plan de acción ofrece una visión de 360°, desde la investigación hasta la transferencia y desde la adquisición de conocimientos hasta la evaluación de soluciones a nivel de parcela y de paisaje. El deseo conjunto de las partes interesadas (industria y autoridades públicas) es trabajar en soluciones a corto y medio plazo, pero también a largo plazo. Por ejemplo, está previsto aumentar nuestros conocimientos sobre el ciclo sexual de estas dos enfermedades fúngicas con el fin de evaluar soluciones de control alternativas basadas en el seguimiento de la fase invernal (profilaxis). Además, este plan de acción pretende garantizar la sostenibilidad de las variedades resistentes mediante el seguimiento de las parcelas y la búsqueda de nuevos genes de resistencia. Finalmente, por supuesto, se trabajará en la evaluación de soluciones alternativas (biosoluciones o métodos físicos). El objetivo de todos estos trabajos, que contarán con el apoyo financiero del ministerio francés de agricultura, es desarrollar técnicas innovadoras que conduzcan en última instancia a un nuevo enfoque técnico y económico. Se trata de combinar palancas a nivel parcelario y regional. Los proyectos presentados por los distintos agentes del sector serán evaluados por un comité científico y técnico copresidido por el INRAE y la Acta.  El conjunto del plan de anticipación de la retirada de tierras (Parsada) tiene una duración prevista de 3 años (2024-2026).

Use of glutathione and a selected strain of metschnikowia pulcherrima as alternatives to sulphur dioxide to inhibit natural tyrosinase of grape must and prevent browning

The enzymatic browning of grape must is still a major problem in oenology today [1] being particularly serious when the grapes have been infected by grey rot [2]. Browning is an oxidation process that causes certain foods to turn brown, which often leads to them being rejected by consumers [3]. This is a particular problem in the case of wine, because grape must is very vulnerable to enzymatic browning [4].

Study of the transfer kinetics of 2,4,6-Trichloroanisole (TCA) between cork and wine – first results

The last step in winemaking is packaging the wines for market placement, while preserving the quality attained during vinification. Since the 1980s, 2,4,6-trichloroanisole (TCA) has been recognised as an incidental and random contaminant of cork, with its migration into wine thought to contribute to ‘cork taint’. This molecule is not a cork component and little is known about how it is formed on trees. Its formation from the chlorine used to wash the cork stoppers, long suspected, has been excluded by the abandonment of chlorine washing.

Characterization of a strain of lachancea thermotolerans, microorganism of choice when facing the climatic challenges of the wine sector

Current climatic challenges in the wine sector require innovative solutions to maintain the quality of wines while adapting oenological practices to changing conditions. This article presents the detailed study of a lachancea thermotolerans strain on matrices typical of the French mediterranean area.

Acceptance of fungus-resistant grape varieties from the perspective of producers and consumers in Germany

Fungus-resistant grape varieties (frgv) are an important field of research in viticulture, as they represent a way of reducing the use of copper-containing pesticides and thus minimising the environmental impact. The literature suggests that resistant grape varieties are a promising solution to the problem of using copper-containing pesticides in viticulture and that their quality has improved in recent years. However, there are still challenges in the acceptance and dissemination of FRGV by wine producers and consumers.

Mousy off-flavor detection: a rapid LCMS/MS method

These days, consumers are interested in food products linked to the environment and the concept of naturalness. They prefer “free” products, such as those with no pesticide residues or no added sulfur dioxide (so2) in wines. In fact, so2 is the most widely used preservative in winemaking, as it has multiple properties at low cost: it is antioxidant, antioxidasic and antimicrobial.
