  • A new IRAC International Statement has been published on considerations for the IRM value of using insecticides on transgenic crops

    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
