- Active ingredient
- Fluopyram (CAS 658066-35-4)
- Chemical class
- Pyridinyl-ethyl-benzamide; FRAC Group 7 SDHI fungicides, which block succinate dehydrogenase (complex II) in fungal respiration.[2][1]

- FRAC Group 7: SDHI fungicides: succinate dehydrogenase inhibitors (pyridinyl-ethyl-benzamides)[2]
- Signal word
- Fluopyram 500 SC: Caution[1]
A fungicide that also works on nematodes
Most fungicides do nothing for nematodes, but this label lists fluopyram as a protectant against damage from certain plant-parasitic nematodes on turf and citrus. Sting nematode is the turf example it names.[1]
SDHI resistance limits
FRAC rates Group 7 SDHI fungicides as medium to high risk for resistance. On ornamentals and crops, the label allows no more than 2 sequential Group 7 sprays before rotating to another group.[2][1]
Where it is used
For nematodes, water the product into the root zone within the label's stated window after spraying. The exception is Anguina pacifica: let the spray dry completely before irrigating.[1]
A vegetated buffer strip between treated turf and ponds or streams cuts runoff, and so does skipping applications when rain or irrigation is due within 48 hours.[1]
Severe patches can get a curative spot treatment at the top rate, repeated up to 4 times, on no more than 10,000 sq ft per acre.[1]
Count every fluopyram product you use toward one yearly total: 13.7 fl oz per acre, or 12.4 fl oz on residential turf.[1]

Safety and environmental hazards
People
Signal word CAUTION: harmful if swallowed or absorbed through skin. Handlers wear long sleeves, long pants, shoes, socks and chemical-resistant gloves such as nitrile or butyl.[1]
Pets
On lawns and other non-farm sites, nobody should enter the treated area until the spray has dried.[1]
Bees and pollinators
This label carries no bee or pollinator warning.[1]
Fish and water
Don't apply to water. The label rates fluopyram as having high potential to reach surface water through runoff for several months, and says it may leach into shallow groundwater under permeable soils.[1]
