Resistance Management Insecticide Compatibility chart
Editor’s note: This article is from the archives of the MSU Crop Advisory Team Alerts. Check the label of any pesticide referenced to ensure your use is included.
To use the Resistance Management Insecticide Compatibility chart, find the cell that intersects the row and column from two compounds of interest.
The shaded code in the intersecting cell represents the compatibility of the two compounds for generational rotation.* (For example, if you plan to use Imidan for first generation codling moth, to check the compatibility of using Warrior for second generation you will follow the column of cells down from Imidan until you reach the cell in the row directly across from Warrior. This intersecting cell is “” thus is NOT a good rotation partner, because of a history of known cross-resistance between these two classes of insecticides.)
The following codes are relevant for lepidoperan pests of fruit crops, including codling moth, Oriental fruit moth, and obliquebanded leafroller:
- The red square represents insecticide chemistries with the same mode of action, thus should NOT be used in a preceding or subsequent pest generation.
- The shaded square represents insecticide chemistries with known cross-resistance, thus should NOT be used in a preceding or subsequent pest generation.
- The white square represents insecticide chemistries that are known to be good rotation partners for a preceding or subsequent pest generation.
* - Recommendations are based on current published resistance studies from Michigan pest populations.
** Insecticides within a given chemical class have the same or similar mode-of-action (MOA).
Key to names of insecticide classes and associated MOA:
- OP - Organophosphates (Acetycholinesterace inhibitors)
- Carb. - Carbamates (Acetycholinesterace inhibitors)
- Pyrethroids - (Sodium Channel Modulator)
- Neonic. - Neonicotinoids (nicotinic acetylcholine receptor agonist/antagonist)
- Spinosyns - (nicotinic acetylcholine receptor agonist)
- MAC - Molt Accelerating Compounds (ecdysone agonist molting disruptors)
- CSI - Chitin Snthesis Inhibitors (benzoylurea and buprofezin)
- JH - Juvenile Hormone Mimic
- Av. - Avermectins (chloride channel activators)
- Ox. - Oxidiazines (sodium channel blockers)
- Vi. - Granulosis virus (viral infection)
- Diamides - (rianodine receptor modulators)
- Pre-mix: products that are formulated with two or more active ingrediants of different MOA
- -Voliam flexi contains the neonicotinoid thiamethoxam and diamide chlorantraniliprole
- -Leverage contains the neonicotinoid imidacloprid and pyrethroid cyfluthrin
- -Tourismo contains the CSI buprofezin and diamide flubendiamide
