Artificial soils were prepared according to calculation sheets - see Overall remarks, attachments.
Ingredients:
• Sand: Kinderspielsand, Bauhaus, 0-2mm dried under room temperature and humidity on tarp
• Gardening substrate: Propagation substrate Suliflor SF1 (>80% organic matter, NPK 14-16-18). Dried at 105°C
• Test product
• Tap water
.
The soils were prepared separately for each treatment by mixing 3 % of dried gardening substrate (>80 % organic matter), 0–8.1 % test product and 97–88.9 % dry sand (0–2mm) and moistenning the content with tap water (20 % of the dry soil weight). The soil was then filled into pots (approximatelly 0.52–0.54 kg dry soil per pot) before planting the seeds.
For details of the pH and conductivity of the final soils - see Overall remarks, attachments.
- Method of application to soil surface (if used):
Test soil
Seeds will be planted in a sandy loam, loamy sand, or sandy clay loam that contain up to 1.5 % organic carbon (approx. 3 % organic matter). Commercial potting soil or synthetic soil mix that contains up to 1.5 % organic carbon will be used. The type and texture, % organic carbon, pH and salt content as electronic conductivity of the prepared soil will be reported.
- Controls: an untreated soil used as a control
- Chemical name of vehicle: water

GROWTH CONDITIONS
Test was conducted under conditions suitable for normal growth of the species and varieties tested. Conditions recommended by OECD 208 (2006) guideline are the following:
- Day/night temperatures: 22 °C ± 10°C

periodically (range-finding test) or distributed in a way removing effects of any potential gradient (definitive test)
- Air exchange rate: by air conditioning system
- Water source/type: tap water
- Volume applied: whenever necessary (every 1–3 days)
- Interval of applications: every 1-3 days
- Method of application: bottom watering (however, initial top watering can be conducted to stimulate seed germination and facilitate movement of the chemical into the soil)
- Any fertilization (if used): yes

Application: 10g/10l watering water. Applied once per week (approximately 75mL per pot)
Application dates: Range finding test: D14, D120; Definitive test: D6, D14, D20
ACCLIMATION PERIOD: no
EFFECT PARAMETERS MEASURED (with observation intervals if applicable) :
Phytotoxicity At least once a week following 50% emergence in controls (chlorosis, necrosis, discoloration, plant growth abnormalities etc.)
Shoot length End of the trial (Shoot length of each survived plant)
Plant biomass End of trial (Dry weight per pot )
VEHICLE CONTROL PERFORMED: yes
TEST CONCENTRATIONS
- Spacing factor for test concentrations: <3
- Range finding study
The range-finding test was conducted with five rates spaced by a factor 10, with the highest rate 10 g product /kg dry soil (10, 1, 0.1, 0.01, 0.001 g/kg dry soil).
Untreated control was included. The test product was mixed with soil.
- Test concentrations
The test product was be applied at five rates, based on the results of a range-finding test, spaced by a factor <3.
1, 3, 9, 27, 81 g/kg dry soil ( Oat, Corn, Soy bean)
0.333, 1, 3, 9, 27 g/kg dry soil (Sunflower, Tomato, Oilseed rape)
- Results used to determine the conditions for the definitive study:
There were no treatment-dependent differences in emergence and survival in any plant species. Decreased shoot length and/or dry shoot weight was detected in all plant species in one or two highest product concentrations. Test concentrations to be included in the definitive test were therefore moved towards higher concentrations in order to cover ideally 20–80% detrimental effects - Nominal and measured concentrations:
- Nominal concentrations
1, 3, 9, 27, 81 g/kg dry soil ( Oat, Corn, Soy bean)
0.333, 1, 3, 9, 27 g/kg dry soil (Sunflower, Tomato, Oilseed rape)

- Reported statistics and error estimates:
- Statistical analyses of the data were performed using ToxRat 3.2. statistical software. There were no substantial and treatment-dependent differences is seedling emergence and survival. These endpoints were thus excluded from statistical analysis. EC10 EC25 and EC50 for shoot length and dry shoot weight were calculated by fitting the data with the 3-parametric normal cumulative distribution function which was followed by Analysis of variance and Test for lack of fit. NOEC was determined by Williams multiple sequential t-test procedure, Step-down Jonckheere-terpstra test procedure, Multiple Sequentially-rejective Median (2x2-Table) Test After Bonferroni-Holm or Multiple Sequentially-rejective Welsh-t-test After Bonferroni-Holm. The most appropriate method was selected on the basis of results of Shapiro-Wilk’s test (testing normality of distribution), Levene’s test (testing homogeneity of variances) and Trend analysis by Contrasts (testing monotonicity of concentration/response). Datailed statictical outputs are in Appendix VII of study report.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Remarks:
- • emergence >70%; • seedlings do not exhibit visible phytotoxic effects; plants exhibit normal variation in growth and morphology for that particular species • mean survival of emerged control seedlings >90% • environmental conditions identical
- Conclusions:
- Selected plant species exposed to the test product mixed in artificial soil exhibited EC10 (in terms of dry shoot weight as the main endpoint) within the range 0.36–5.45 g product/kg dry soil, and EC50 within the range 3.85–34.96 g product/kg dry soil.
- Executive summary:
A GLP glasshouse trial was conducted to evaluate the effects of a UVCB substance on seedling emergence and early growth of six representative plant species following exposure to the test item. The study was conducted in accordance with the OECD Guideline (208, 2003: Terrestrial Plant Test: Seedling Emergence and Seedling Growth Test).
Seeds of six plants (oat, oilseed rape, tomato, corn, sunflower and soybean) were planted into pots filled with artificial soils containing 5 diferent concentrations of the test item and an untreated soil used as a control. The test item concentrations were selected on the basis of a range-finding test conducted beforehand. Seedlings were observed for 2 weeks after 50% emergence detected in the control and marks of phytotoxicity were recorded. Final assessment conducted 3 weeks after test initiation included determination of mean shoot length and mean dry weight per plant in each treatment as the main endpoints.
No effect of the test item on the seedling emergence and survival was detected in all plant. Effective concentrations causing 10, 25 and 50% reduction of final shoot height and dry weight (EC10, EC25 and EC50) and No Observed Effect Concentrations (NOEC) are summarised below:
