The paper reports on the sensitivity monitoring executed by DuPont and collaborators in Italy, Spain, Greece since 2009 in order to detect possible sensitivity shifts of T. absoluta from baseline sensitivity to the diamide insecticide chlorantraniliprole (MoA group 28). The results of the 2014 bioassays revealed the first cases of T. absoluta resistance to diamide insecticides in South-East Sicily. The potential integrated control strategies are discussed, aiming to prevent further directional selection of resistance alleles via the adoption of stringent…
A video from CropLife International and the Insecticide Resistance Action Committee (IRAC) that explains the importance of mode of action as the basis for effective and sustainable resistance management to preserve the utility and diversity of available insecticides and acaricides. The video can be viewed in English or watch it in Spanish, Mandarin or Portuguese….
…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…
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…
The IRAC Plant Biotechnology Working Group has completed a short poster brochure discussing the use of Bt corn to manage fall armyworm, Spodoptera frugiperda, in the Asia-Pacific region. The brochure complements IRAC’s poster and brochure developed in 2021 entitled “Manage fall armyworm in 3 steps”. The 3 steps are 1) Incorporate agronomic actions, 2) Identify pest and decide when to treat, and 3) Control FAW using IRM principles. The main IRM principle relayed in this brochure is the rotation in modes of…
The IRAC video explaining the importance of mode of action as the basis for effective and sustainable resistance management is now available in Spanish, Portuguese and Chinese…
An easy to use database that allows you to identify all insecticides in any given mode of action group. The app allows the user to filter and search by either MoA group or insecticide and is free to download from the iTunes Apple Store or the Google Play Store. Suitable for use with tablets and phones….
The Tomato Leafminer Tuta absoluta is a pest of great economic importance with high reproduction capabilities and short generation life cycle which makes it at risk of developing resistance. The pest has spread from L. America, where there is already resistance to a range of MOA groups, to Europe, the Middle East and N. Africa. Using the Tuta absoluta poster IRAC is taking pro-active steps to advise on key management strategies to evaluate and reduce the spread of resistance….
The IRAC Methods Team have produced another video in their series of test method videos. This video shows how to carry out Method No.030 evaluating the susceptibility of stinkbugs to insecticides from mode of action groups, 1A (carbamates), 1B (organophosphates), 3A (pyerethroids), and 4A (neonicotinoids). The method has been validated for Euschistus heros and can be used for susceptibility baseline testing and resistance monitoring….
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….
