What is Sulfaxaflor?
Sulfoxaflor is a sulfoximine, a newer insecticide class that was first registered by EPA in 2013. It is effective against pests that are becoming resistant to carbamate, neonicotinoid, organophosphate and pyrethroid insecticides.
Sulfoxaflor is an important and highly effective tool for growers that targets difficult pests such as aphids and tarnished plant bugs (lygus). These pests can cause significant economic loss leading several states to request emergency exemptions in recent years. There are few viable alternatives for sulfoxaflor. In many cases, alternative insecticides may be effective only if applied repeatedly, whereas sulfoxaflor typically requires fewer applications resulting in less risk to non-target pests and plants.

Excerpt from the EPA release dated July 12, 2019…
“Today, the U.S. Environmental Protection Agency (EPA) is issuing a long-term approval for the insecticide sulfoxaflor ̶ an effective tool to control challenging pests with fewer environmental impacts. After conducting an extensive risk analysis, including the review of one of the agency’s largest datasets on the effects of a pesticide on bees, EPA is approving the use of sulfoxaflor on alfalfa, corn, cacao, grains (millet, oats), pineapple, sorghum, teff, teosinte, tree plantations, citrus, cotton, cucurbits (squash, cucumbers, watermelons, some gourds), soybeans, and strawberries.”
To further protect pollinators from potential exposure, EPA requires the following crop specific restrictions:
- Citrus: Only one application is allowed between 3 days before bloom and until after petal fall per year
- Ornamentals: Do not make more than one application during bloom. The single application during bloom must not exceed a rate of 0.071 lb ai/acre.
- Pome Fruit, Stone Fruit, Tree Nuts and Pistachio: Do not apply this product any time between 3 days prior to bloom and until after petal fall.
- Small Fruit Vine Climbing & Low Growing Berry, Tree Plantations: Do not apply this product any time between 3 days prior to bloom and until after petal fall.
