IRAC España ha emitido una nueva alerta sobre resistencias de Ceratitis capitata en cítricos. Desde hace varios años están descritos casos de resistencias de Ceratitis capitata a piretroides (MdA nº 3A), básicos en la estrategia de control de la mosca de la fruta en cítricos, tanto en trampas de captura masiva y/o técnicas de “atracción y muerte” sin captura como en cebo durante el periodo de cambio de color de la fruta. La colocación de trampas al inicio de…
The updated Japanese translated versions of the IRAC MoA Classification Scheme, the Classification Table, the MoA Poster showing the chemical structures, the Procedure for classification of new actives and MoA labeling advice has now been posted on the website with links on the Japan and MoA landing pages….
Growers in Canada can get ahead of insecticide resistance with the help of new resources on ManageResistanceNow.ca. The website, which compiles the most up-to-date knowledge on pesticide resistance in Canadian agriculture, now includes best practices for managing insecticide resistance. “More than one-third of Canadian growers are concerned about the rise of insecticide resistance in the next few years,” says Pierre Petelle, president and CEO of CropLife Canada. “It’s critical to adopt best practices to manage resistance, both to protect…
On April 4, 2019, IRAC-BR and the Copacol cooperative (Cafelândia-PR) organized the I WORKSHOP ON INSET RESISTANCE MANAGEMENT (MRI) to discuss the validation of regional MRI recommendations. The event brought together experts on insect resistance and the staff of Copacol. Initially the process of evolution of insect resistance to insecticides and Bt plants and MRI strategies was presented and discussed. The IRAC-BR representatives presented the current susceptibility data to insecticides in the main pest species that attack soybean and…
The new Global Resistance Management (GRM) Mode of Action App, released earlier this year by the Resistance Action Committees (IRAC, HRAC FRAC), has just been updated with additional features. The App combines the information on the Resistance Action Committee’s standalone Mode of Action Apps into one application for ease of access by the user. The individual IRAC, FRAC and HRAC Mode of Action Apps are still available and all applications can be downloaded from the Apple App and Google…
See the poster. Summary of findings: In the majority of countries surveyed, pyrethroid resistant populations of pollen beetle dominate (> 60% are resistant). From the countries surveyed, it is only in Switzerland that susceptible populations dominate but sample size was considered too small to be representative of the overall country situation. During 2014, only 11% of pollen beetle populations surveyed in Europe could be classified as pyrethroid susceptible. After an initial decline in the number of susceptible pollen beetle populations…
Conclusions from the program: An area wide insecticide rotation program is the best long term option to prolong efficacy of available insecticides for FAW management in Puerto Rico Developing and implementing area wide programs requires a lot of effort and coordination Area wide programs are a hard sell, getting 100% compliance on a voluntary basis not easy Enforcing a fallow period may be necessary as rotation alone may not be enough to restore or maintain the efficacy of available…
The 57th IRAC International Meeting was held in conjunction with IRAC Japan and IRAC Asia in Kyoto. This incorporated a visit to the Annual Meeting of Japanese Society of Applied Entomology and Zoology in Osaka where IRAC presentations were given in a seminar sponsored by the Japan Crop Protection Association on 14th March. Further meetings took place during the week as follows: 15th March: Meeting of the IRAC Executive and Crop Protection teams 16th March: Seminar at Kyoto university…
IRAC España ha emitido una revisión de la alerta sobre resistencias de Ceratitis capitata en cítricos. Los insecticidas de los modos de acción 3A, piretroides, y 5, spinosines, son herramientas básicas de las estrategias de control de la mosca de la fruta en cítricos. Debido a la detección de poblaciones resistentes a ellos, se aconseja su alternancia con otros modos de acción, especialmente en las zonas donde se observe reducción de las eficacias de control, además de fomentar el…
The MoA posters with the chemical structures for insecticides/acaricides and for nematicides and the small MoA brochure (now including nematicides) have been updated to correspond with the latest versions of the IRAC MoA Classification. The documents can be downloaded from the website and printed copies will be available in early 2022. The insecticide/acaricide poster is in English but other language version are in preparation….
