In South Africa, it will be critically important to have a harmonised approach to IRM for FAW across the industry and across technologies. This approach should combine a clear and simple structured refuge policy which does not confuse growers between the requirements for FAW and maize stalk borers in South Africa, and which enables a high grower compliance. There are several commercialised Bt-products in South Africa which are very similar. This approach is in the best interests of the seed industry, growers and South African consumers. The new guidelines have now been published on the IRAC website.
Conclusions from the program:
The IRAC Mode of Action App in IOS and Android has been updated to include the latest changes to the MoA Classification (Ver. 9.3, June 2019). This incorporates some additional MoA Groups including bio-insecticides. The update also includes some additional features such as an active ingredient search and links to the latest IRAC News on the IRAC website.
Fall armyworm (FAW) (Spodoptera frugiperda) is a serious pest in corn, if uncontrolled; this pest can cause a severe damage of the breeding materials of the seed industry at Puerto Rico. One of the tools to manage FAW is the use of insecticides of different modes of action. However, FAW has a tremendous ability to develop resistance. Therefore, monitoring the susceptibility or resistance of FAW to insecticides is critical to establish a successful insecticide resistance management plan (IRM). Monitoring of resistance requires the knowledge of specific methods of insecticide bioassays and analysis of data. Consequently, Michigan State University, IRAC International, and Corteva Agriscience in partnership with PRABIA offered a training course in methods of bioassays for FAW.
The training consisted of classroom training and hands-on laboratory and field experience and reviewed concepts associated with insecticide mode of action and resistance to synthetic compounds. A review of the theory and practice of laboratory bioassays methods for detection of insecticide resistance including leaf disc (IRAC Method No. 007) and insecticide incorporated diet (IRAC Method No. 020) was performed by the participants. In addition, evaluation of the larval mortality was performed by the participants of this training. Probit procedure from SAS and/or POLO program were used to analyze mortality data of the laboratory bioassays, and results of the data analysis were discussed.
IRAC España ha emitido una alerta de aviso de resistencia de Cydia pomonella a diversos modos de acción en frutales de pepita. En los últimos años se están produciendo numerosos casos de problemas de control de Carpocapsa (Cydia pomonella) en el valle del Ebro. Además, se ha detectado un incremento de las poblaciones tanto de esta especie como de Grapholita molesta en manzano, dificultando la protección del cultivo.
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 corn crops, such as: Spodoptera frugiperda, Chrysodeixis includens, Helicoverpa armigera, Euschistus heros and Bemisia tabaci.
For the practical part of the Workshop, the participants were divided into working groups for case studies looking for solutions to regional problems, with a view to MRI. Among the pest insects of regional importance are the management of the brown bug (Euschistus heros), the belly-green bug (Dichelops melacanthus) and the carpiaceous caterpillar (Spodoptera frugiperda). The current management of these species was discussed and how it could be improved, taking into account the production system of the region, in order to delay the evolution of resistance. The possibility of implementing MRI strategies at regional level and monitoring the susceptibility of populations of these sites in partnership with IRAC-BR consultants was also discussed, since Copacol has a large area of coverage in the western region of Paraná. The I Workshop on MRI was very productive, as it allowed discussion on the approach of IRAC-BR with the technical staff of Copacol. on the current management practices of the main soybean and corn pest insects in the western region of Paraná, as well as, what MRI strategies can be put into practice at the regional level to delay the evolution of resistance. IRAC-BR thanks Copacol for the reception and organization of this Workshop.
The Ontario Pest Management Conference (OPMC) Steering Committee commissioned this White Paper as a call to action, to stimulate focused dialogue and set in motion a compelling strategy to proactively engage Canadian agriculture stakeholders in pesticide resistance management (RM).
Its intention is to set out a coherent approach to align Canadian agriculture stakeholders in RM engagement. It is an agenda for renewing government, university, industry and producer investment in a RM framework — to strengthen the commitment, communication and implementation of RM at the farm level.

IRAC España ha emitido una Alerta sobre resistencias de Tuta absoluta a diamidas (MoA 28) en tomate. En los últimos meses se están produciendo muchos problemas en el control de Tuta absoluta en las principales zonas productoras de tomate de invernadero de Almería y Murcia, detectándose un claro incremento de la presión de la plaga y dificultando una protección correcta de este cultivo.
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.
