Materials and methods
- Principles of method if other than guideline:
- BASF-Test: In principle, the methods described in OECD Guideline 401 were used. 5 young male (mean body weight: 254 g) and 5 young female rats (mean body weight: 190 g) were used per dose group. The substance was applied as a single oral dose (10 ml/kg bw of an 3.16-31.6% emulsion of the test substance in olive oil). The post-exposure period was 14 days, after which the animals were sacrificed and subjected to a gross-pathological examination. Findings were recorded 1 h, 24 h, 48 h, 7 d and 14 d after application of the substance.

Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- ca. 630 mg/kg bw
- Mortality:
- No animals died in the 316 mg/kg bw dose group. In the 464 mg/kg bw dose group, no animals died 1 h after substance application, one female animal was found dead after 24 h and an additional female was found dead after 14 days. In the 681 mg/kg bw dose group, no animals died after 1 h , 1/5 male animals was dead after 24 h, whereas 5/5 female animals were found dead after 24 h and no additional animals died until the end of the observation period (14 days). In the 1000 mg/kg dose group, 3/5 male and 3/5 female animals were dead after 24 h, but none died after 1 h and no additional animals died until the end of the observation period (14 days). In all other dose groups, no animals died after 1 h but 5/5 male and 5/5 female animals were dead after 24 h.
- Clinical signs:
- other: The animals of all dose groups showed dyspnea, apathy, staggering, atony, tremor, spastic movements, opisphotonus and diarrhea in varying degrees. Some animals assumed a lateral position.
- Gross pathology:
- Gross pathology revealed acute dilatation of the heart, acute hyperemia, acute gastritis and diarrheic content of the intestines with strong injection of the blood vessels in the sacrificed animals of the three highest dose groups; animals of the 1000, 681 and 464 mg/kg bw dose groups had dilatation of the heart, acute hyperemia, diffuse irritation of the stomach (gastritis) and additionally conglutination of the gastric mucosa with the liver, spleen, diaphragm and peritoneum in the 1000 mg/kg bw dose group. Substance precipitation in the abdomen was not observed in the 464 mg/kg bw dose group. Both sexes showed comparable results.
