Title DFO + FLU 375 SC:Acute Oral Toxicity Up-And-Down Procedure in Rats

Date 12-NOV-20

2. a) Is an extension needed to translate the document?


3. Type of incident identified in the study

Increased health or environmental risk

4. Describe the incident identified in the study (e.g. study demonstrates an increased risk to non-Hodgkin's Lymphoma after exposure to pesticide X)

In the acute oral up -down -procedure the oral LD50 of this formulation was estimated to be 1030 mg/kg of body weight. This is a US EPA Toxicity Category III. The oral LD50 for difenoconazole is 1453 mg/kg (Category III) and the oral LD50 for fluopyram is 2000 mg/kg (Category III). These actives are mixed with other actives in other formulations and the oral LD50 for all are a Category Ill. While there was no change in the Category there were deaths in the study. Given the formulation LD50 is lower than for each of the active ingredients this may be potentially reportable.
