Spirotetramat resistance in Australian green peach aphids
7 August 2023
The resistance of green peach aphid (Myzus persicae, GPA) to numerous chemical mode of action groups makes it an ongoing management challenge. In Australia, GPA has evolved high-level resistance to synthetic pyrethroids and carbamates, and low-level resistance to organophosphates and neonicotinoids. Quite recently, low-level resistance to sulfoxaflor has also evolved in some Australian field populations.
Research published in 2022 found populations of GPA with resistance to spirotetramat, the active ingredient in Movento® 240 SC Insecticide, as well as several generic products containing the same active ingredient. Spirotetramat, a Group 23 insecticide, is an important tool in GPA management in vegetable crops in Australia.
