Simple in-field test to detect pyrethroid resistance in redlegged earth mites
Guide
Redlegged earth mites (RLEM) resistant to synthetic pyrethroids are an increasing problem across southern Australian grain and pasture growing regions, but new and easy-to-use methods have been developed to identify resistance.
If you have experienced a chemical control failure or suspect insecticide resistance to synthetic pyrethroids, we have developed a simple test that will help confirm whether your local mite population is resistant to this group of chemicals. Pyrethroids includes active ingredients such as bifenthrin and alpha-cypermethrin.
This method can be readily applied in the field using commercially available materials and without the need for training. Download this guide to find out how to detect pyrethroid resistance in your local mite population.
