Crop Protection
Overview
Inter company project teams are set up in response to local, national or international insecticide resistance issues. The Crop Protection Project Teams typically comprise of relevant company representatives and local experts and have specific resistance management objectives and timelines and are set up and disbanded as needed and agreed by IRAC.
Pollen Beetle
The pollen beetle working group was set up early in 2007 and includes representitives from Syngenta, Bayer CropScience, Dow Agrosciences BASF. Makhteshim, DuPont and FMC as well as European regulators. European monitoring data from the different companies and countries has been shared to provide an overall picture of pollen beetle resistance in Europe.

Codling Moth
The Codling Moth Team has been operating for 2 years and consists of IRAC members and local experts. The focus of the team so far has been in developing standard monitoring methods. The Team leader is Max Angst from Syngenta based in Basle, Switzerland.

CFC Project (Completed)
The Common Fund for Commodities project was "Sustainable Control of the Cotton Bollworm (Helicoverpa armigera) in small scale Cotton Production Systems" This was a large international effort with work being carried out in number of countries and research establishments.
The Components of the project were as follows:
- Reviews of insecticide impact on targets/beneficials
- Regional resistance monitoring
- Cross resistance patterns
- Principles of mixtures
- Lab resistance v. field control
- Spray practices
- Insecticide quality kits
- Resistance detection kits
- Field demonstration of control in Asia
- Handbook-Economic control of H.armigera in Asia
Further information on the project can be found below:
Acaricide IRM (Completed)
In-house research and contemporary publications indicated that 4 acaracides acted at the same rotenone site in the mitochondrial electron transport chain 5-9. With a long history of resistance development, the potential for spider mites to develop cross-resistance to these mitochondrial electron transport inhibitors (METIs) was recognised.
IRAC responded to this challenge by recommending a radical solution. Member companies agreed to limit applications to one METI application per location in any one year. In order to gain maximum compliance, it was agreed that competitor products should be referred to by name on each other's labels.
This unprecedented level of inter-company co-operation was made possible by IRAC and provides an important benchmark in the history of resistance management as it was in place before resistance had developed in Europe.
IRM for Colorado Potato Beetle (Now Completed)
|
In the years 1994-1997, following a commission of IRAC, monitoring of the susceptibility level of large numbers of a CPB population was carried out in Poland in different regions of the country. The study revealed a high degree of susceptibility variation to each of the two insecticides tested. This indicated the potential for the development of resistance in the CPB. To combat this situation, an IRM strategy was worked out by Polish research institutes in co-operation with IRAC.
