Updated guidelines for rotating seed treated, soil and foliar applied insecticides
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. There are limited insecticide modes of action available for use either as soil or seed treatments, therefore, the judicious use of the available modes of action is essential for sustainable control of the insect pests targeted by these applications. The updated IRAC guidelines provide more information.

Resistance Alert for Cotton Aphid (Aphis gossypii)
Cases of Insecticide resistance associated with the cotton aphid (Aphis gossypii) have been reported since the mid-1960‘s. Resistance to organophosphate, carbamate, cyclodiene organochlorine and pyrethroid insecticides are considered as globally widespread.
More recently there have been substantive reports of resistance to the nicotinic acetylcholine receptor competitive modulators (IRAC group 4). This group of chemistries has provided effective control of the cotton aphid for many years, but now reports of resistance are increasing.

Successful workshop on insect resistance management in Brazil
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 Case for the Canadian Agriculture Industry to Proactively Engage in Pesticide Resistance Management
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. Read the full White Paper.

Report from IRAC India Meeting, Delhi, 4-5th February 2019
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.
