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 Test Methods for Myzus persicae nymphs (No. 023) and for Aphis gossypii nymphs (No. 024), both for use with the MoA Group 28 active, cyantraniliprole, have been developed and posted on the website by the IRAC Methods Team. The methods are available for downloaded from the IRAC website via the links: Method No. 023 and Method No. 024.
IRAC Test Method (No. 019) for aphids has just been finalised, approved and posted in the Methods Team area of the IRAC website. The method is suitable for monitoring resistance in a number of different aphid species and product classes, the details of which along with a method description are outlined in the Test Method document.
