Maps for the 22 weeds with “official” resistance in France have been updated and are now online! They are available here.
This note was elaborated by ACTA, Arvalis, INRA, ITB, Terres Inovia, FNAMS and Agrosolutions with the participation of COLUMA (Végéphyl) for field data. In addition to a brief summary of resistance mechanisms and a description of good weed control practices (those that do not facilitate the evolution of resistance!), it is accompanied by 17 technical […]
This classification proposed by R4P makes it possible to assign a unique code to all active substances sharing the same mode of action, regardless of their use. All details here. Files are also archived online at this address, with the classification of insecticides, acaricides and fungicides : https://osf.io/ubhr5/
The poster of the main cases of herbicide resistance has just been updated (March 2019). It is available in the section “Resistance watch”.
NORBARAG is a collaborative network between Scandinavian and Baltic countries. Its work focuses on pesticide resistance and efficacy evaluation. The network includes representatives from Denmark, Estonia, Finland, Latvia, Lithuania, Norway and Sweden. Its objectives and functioning converge with those of R4P. In order to inspire each other, the R4P network presented the activities it carries […]
Registration for the two days of training and exchanges on resistance to plant protection products (JÉR 2019) is extended until noon on 6 March 2019. There are only a few places left, so register here as soon as possible. We hope to meet many of you in Versailles!
This note, drafted by a working group of experts from Anses, INRA and Terres Inovia, reviews the current status of resistance of Sclerotinia sclerotiorum to the main fungicide families currently authorised and makes recommendations for sustainable management to limit the risks of resistance evolution and maintain the efficacy of the available solutions. This note (in […]
This note, written by representatives of INRA, Anses and Arvalis – Institut du Végétal, provides an overview, by disease and mode of action, of resistance to fungicides used to control diseases in cereals and makes recommendations to limit the risk of resistance evolution and maintain sufficient efficacy. This note (in French) can be downloaded here […]
For the first time, the training and exchange days on pesticide resistance (Journées d’Échanges sur les Résistances or JÉR) will also be held in Québec on February 14 and 15, 2019. This Québec edition is made possible thanks to the collaboration with the IRDA (Institut de Recherche et de Développement en Agroenvironnement) in Saint-Bruno-de-Montarville. This […]
Gestion durable de la flore adventice Chemical-based weed management is being questioned just like intensive agricultural model. Under societal pressure, public authorities are encouraging the agricultural sector to develop more sustainable production methods that are not as dependent on herbicide use. This collective work explores ways of controlling and regulating weed that integrate all environmental […]
