- key study
- Study period:
- Study initiated/completed: 01 March-2001 to 01 April 2001.

- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: OECD TG 208 - Based on the Draft Document - Proposal for update, July 2000
- Deviations:

- Remarks:
- Data were generated in a non-GLP efficacy screening. However, the screening was performed according to standardised study protocols.
- Analytical monitoring:
- no
- Details on preparation and application of test substrate:
- Spray treatments were applied in an automatic spray chamber for primary screening tests. The spray chamber was adjusted as follows: pressure 3 bar; height of spray boom 45 cm; nozzle type: 8003E; water application rate to the target area 1000 litres/ha; the material was applied in single applications of 180; 360; 720 and 1080 g a.s./ha. For spray treatments the test solutions were briefly shaken and then directly applied through a spraying nozzle. Each application was automatically performed by touching a button. Prior to each application of new test material, the spray nozzle was cleaned at the rinsing station. The adjustments of the spray chamber were recalibrated every six months.

- Remarks:

- Total exposure duration:

- Test temperature:
- The plants were kept at a day/night cycle of 22°C/15°C, respectively.
- Moisture:
- The relative humidity in the test chamber was set at 50%.
- Details on test conditions:
- Growing Conditions: The plants were kept at a day/night cycle of 22°C/15°C, respectively. The relative humidity in the test chamber was set at 50 % and the duration of illumination (8000 lux) was 14 hours to 10 hours in a day/night rhythm. Plants used for pre-emergence treatments were sown, sprayed with the test material and directly placed under the specified growing conditions. The final evaluation was done 21 days after treatment initiation.
Horticultural conditions:
Pre-emergence: Seeds of all mentioned plant species were planted together into soil (sandy loam, organic matter of 2.5%-3%) in greenhouse pots. Typically 10 seeds of each of the 11 species were sown 24 hours prior to application of the test substance. The soil allowed good germination. Growing plants were watered as needed.
Post-Emergence: Seeds of all mentioned plant species were planted together into soil (sandy loam, organic matter of 2.5%-3%) in greenhouse pots. Typically 10 seeds of each of the 11 species were placed. Plants were grown in the greenhouse for about 14 days prior to application of the test material.
Rating scale for visual observations and data evaluation: Evaluation of phytotoxicity was done by visual observations using a rating scale of 0 to 100 %,
where 100 % represented complete destruction of above ground parts and 0 % represented no visual damage (normal growth) as compared to untreated plants. - Nominal and measured concentrations:
- The material was applied in single applications of 180; 360; 720 and 1080 g a.s./ha (nominal).

- Remarks on result:
- other: no effects
- Details on results:
- In the pre-emergence- and the post-emergence-test all tested plants showed no phytotoxicity up to the highest application rate of 1080 g a.i./ha.
Based on the NOEC of 1080g/ha, this was converted to mg/kg dw soil using the defaults of default values of soil depth of 10 cm and soil density of 1500 kg/m³.
The calculated NOEC is 0.72 mg/kg dw soil - Validity criteria fulfilled:
- yes
- Conclusions:
- In the pre-emergence- and the post-emergence-test all tested plants showed no phytotoxic up to the highest application rate of 1080 g a.s./ha

Description of key information
In the pre-emergence- and the post-emergence-test all tested plants showed no phytotoxicity up to the highest application rate of 1080 g a.s./ha. This was calculated to be 0.72 mg/kg dw soil using the default values of 10 cm soil depth and 1500 kg/m³ soil density.
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for terrestrial plants:
- 0.72 mg/kg soil dw
