The initial objectives of the team will be to investigate the resistance risk of nematicides and to develop a mode of action classification scheme similar to that available for insecticides and acaricides. Information will be posted on the website under Nematode Team.
The application of an insecticide to the soil, either as a seed treatment or as a direct application, is designed to either control soil borne insect pests or provide systemic control of pests above the ground. The general principles of resistance management apply to seed and soil treatments, as with foliar applied insecticides, however there are some additional factors that should be considered as outlined the the latest statement from IRAC titled: IRAC International statement on the resistance management considerations of utilizing soil & seed applied insecticides
The new IRAC leaflet has been designed in conjunction with CropLife International providing growers with essential information on insect resistance management and the significant benefits for growers. The leaflet is in English at the moment but an editable version will be available shortly so that it can be translated into the local languages and targeted for specific countries and sectors.
The MoA Classification has been updated by the IRAC MoA Team and the updates approved by the IRAC Executive. The latest version of the Classification Scheme can be downloaded from the IRAC website. The English version of the IRAC Chemical Structures Poster and the small IRAC MoA Booklet have also been update and can be downloaded from the website.
The popular IRAC Mode of Action Classification mini-booklet and the poster showing the chemical structures has been updated and reprinted. The previous printed editions related to earlier version of the classification scheme but these latest editions are based on the most recent classification version 7.3. In addition the format and layout has been improved and many of the chemical structures on the poster have been redrawn to standardise the nomenclature. Both the booklet and the poster can be downloaded from the website.
If you would like printed copies please contact your IRAC Member Company representative or Alan Porter, the IRAC Coordinator ([email protected]). You can also use the contact form link at the bottom of the website pages.
Chemical insecticides can be applied to conventional and transgenic crops expressing insecticidal proteins. When conducting a pest management program, it is important to take into account IRM considerations for both the transgenic trait (i.e. refuge adoption) and the chemistries being employed (both foliar applied and seed treatments). The IRAC Statement lists the key factors that should be considered when assessing the IRM value of applying the chemical insecticide.
IRAC held their 49th International Spring Meeting at the Hamner Conference Center, Research Triangle Park, NC hosted by BASF and Bayer CropScience on 17-20 March 2014. There were 9 sessions held over the 4 days including various working group planning meetings, a meeting of the IRAC Executive, and an “International Day” with four invited guest speakers. Presentations from the ‘International Day’ can be found on the IRAC website Resources Page by filtering for Spring Meeting 2014. In addition to the normal topics it was also a celebration of the 30th anniversary since the formation of IRAC in 1984.
The IRAC International Plant Biotechnology Committee has just published two position papers for insect resistance management in transgenic crops. The papers, available on the IRAC website, are titled: “Seed Blends for Resistance Management of Insect-Protected Transgenic Crops” and “IRM for Transgenic Crops in Small-Holder Agricultural Systems”
