Fate

Toxicology
Mammals: Acute oral LD50 for rats and mice >15,000 mg/kg. Acute percutaneous LD50 for mice >5000 mg/kg. In 2-year feeding trials, no-effect level for rats was 600-2000 mg/kg diet.

Methods

MRLs

Uses
Control of scab, Alternaria leaf spot, powdery mildew, Monilia disease, and fruit spot of apples; melanose and scab of citrus fruit, coffee berry disease, and pink disease of rubber.

Notes
There is no ISO common name for fluoromide. The name “fluoroimide” is approved by the Japanese Ministry of Agriculture, Forestry and Fisheries.
The spelling “fluoromide” has also been used.
