The 44th meeting of IRAC International was held at the end of March/beginning of April and consisted of a mixture of concurrent IRAC working group meetings and reviews, a meeting of the Executive Committee, IRAC España and an international session which included presentations from local Spanish experts. The meeting also was an opportunity to celebrate the 25th anniversary of the formation of IRAC and was arguably the most successful ever with an attendance of 45 international delegates. There was an…
IRAC held their 48th International Spring Meeting at Syngenta’s Research Centre in the UK on 18-22 March 2013. There were 12 session held over the 5 days including various working group planning meetings, a meeting of the IRAC Executive, and an “International Day’ with a session of guest speakers covering different aspects of resistance and resistance management. Presentations from the ‘International Day’ can be found on the IRAC website Resources Page and by filtering for Spring Meeting 2013…
After much discussion and debate the final draft of this popular poster is now with the printers and 2000 copies will be produced for distribution by IRAC members. The poster is based on the latest version of the Classifciation scheme (version 6.3) which includes new actives cyenopyrafen and cyflumetofen. Copies of the poster should be available in November.
IRAC International held their 46th meeting in the CropLife International offices in Brussels on 28th – 31st March 2011. This was our biggest ever meeting with 46 participants, including visitors from the European resistance action groups as well as IRAC representatives from around the world. The meeting consisted of a mixture of concurrent IRAC working group sessions, a meeting of the Executive Committee and an International review day. There was an excellent exchange of information with around 40 presentations made…
IRAC International held their 45th meeting in the CropLife America offices in Washington DC on April 26-29th 2010. The meeting was attended by around 35 particpants and consisted of a mixture of concurrent IRAC working group meetings and reviews, a meeting of the Executive Committee, IRAC US and an International Session which included discussions and presentations from invited guests including EPA, EPPO, CropLife international and the NAICC Consultant Association. There was an excellent exchange of information with around 40 presentations…
Urgent research to understand the nature and extent of insecticide resistance in an increasingly damaging pest of peas and beans is underway at Rothamsted Research. The work is in response to reports of failure to control the pea and bean weevil (Sitona lineatus) with pyrethroid sprays, which are a special chemical class of active ingredients found in many modern insecticides used by growers. For further information see the resistance alert on the Rothamsted Research website…
In a situation in which running real-world experiments is impractical (or even impossible), computer simulations offer a powerful solution to understand complex problems. This is exactly the case of resistance-evolution prediction: Although fast from an evolutionary perspective, the time and spatial scales involved in this process are simply too large to be dealt with experimentally. The underlying evolutionary processes of resistance development are relatively well known, however. With this knowledge, researchers can build mathematical models to describe and mimic the…
2000 copies of this latest version of the poster have now been printed and are available for distribution. Copies have been sent to the IRAC Executive members for further distribution to other team members. To view or download the file click here….
At the recent first conference call of the new IRAC Lepidoptera WG it was agreed that the first priority was to investigate the resistance of the tomato leafminer Tuta absoluta and the diamond back moth Plutella xylostella. Initial actions identified were to develop educational posters on both these pests outlining the resistance status, mechanisms and chemistry involved. The objective is to have the posters completed by the time of the IRAC Spring Meeting in April….
The IRAC Lepidoptera WG has just updated the popular Diamondback Moth (Plutella xylostella) poster that outlines the basic biology, resistance mechanisms and management along with general IRM strategies and modes of action available to control this pest. See the poster….
