On the 4th and 5th of February a meeting of IRAC India was held in Delhi. In addition to the members of the IRAC India team there was active participation from IRAC International, IRAC Asia and Croplife India. The goals of the workshop were to establish working priorities for IRAC India in both the short term and the long term, ensuring that prioritised insecticide resistance issues are being addressed and that IRAC India is providing key technical information to support the implementation of insecticide resistance management.
The IRAC India team agreed that development of supporting materials for resistance management in rice and cotton as well as specifically for the invasive pest fall armyworm (Spodoptera frugiperda) were the key priorities and therefore an action plan was developed. The inclusion of mode of action icons on product labels and development of effective communication pathways to growers and retailers were also identified as key priorities that the team will work upon.
On the second day the group were joined by representatives of the Ministry of Agriculture & Farmer Welfare, the Farmers’ Federation, Indian Agricultural Research Institute and Central Institute for Cotton Research to gain further insights on how to support and communicate the implementation of insecticide resistance management.
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.

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.
