Neonicotinoids such as Admire Pro, Platinum, etc., are often used at-planting and should not be followed by a foliar application of a neonicotinoid due to resistance development in Colorado potato beetle. The Colorado potato beetle has developed resistance to more than 50 insecticides. Switching among IRAC groups is a good resistance management strategy to slow the development of resistance. Instead of another neonicotinoid, select an insecticide from the options below if needed.
