- - Method of mixing into soil (if used):The control and test item treatments were applied once at the beginning of the study.
Soil amount per test concentration and control: 16.86 kg, divided into two parts, each 8.43 kg
The respective test item amount was weighed out for each test item concentration, demineralised water was added and stirred at approximately 50 °C for 1 hour on a magnetic stirrer. Afterwards the test item solution and an appropriate amount of demineralised water (adjusting the soil to a moisture of 50 % of the maximum water holding capacity (WHC)) was added to the soil. Subsequently the soil was mixed carefully with the soil using a mixer to ensure a homogeneous distribution. The treated soil was transferred to the test container and the seeds were sown

EFFECT PARAMETERS MEASURED (with observation intervals if applicable) :
During the 21 day observation period the plants were observed every 7 days for number of emerged seedlings, number of dead plants and visual phytotoxic effects. The rating of the treated plants was done in relation to the control plants. Observations included all variations, either inhibitory or stimulatory, between the treated test replicates and the untreated control replicates. Such variations were phytotoxic symptoms (chlorosis, necrosis, wilting), formative effects and growth and development rates. At the end of the study shoot height and shoot fresh weight were measured.

(1) Alteration of form and appearance (deformation)
(1.1) Curling / twisting / sticking or other deformation of the leaves
(1.2) Change of appearance

Negative values = promoted growth - Results with reference substance (positive control):
- No reference substance tested
- Reported statistics and error estimates:
- The percent inhibition of biomass growth (shoot height, shoot fresh weight) and rate of emergence were calculated in relation to the control.
One Way Analysis of Variance (ANOVA) was carried out for the determination of statistically significant differences compared to control replicates. When
running a One Way Analysis of Variance a Normality test and an Equal Variance test were done first. P-values for both Normality and Equal Variance test are
0.05. The -value for ANOVA (acceptable probability of incorrectly concluding that there is a difference) is =0.05.
EC10, EC25 and EC50 values were calculated by sigmoidal dose-response regression. Calculation of the confidence intervals for EC-values was carried out using standard procedures.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Potential toxic effects of the test item were assessed on day 7, 14 and 21 by visual observations (phytotoxic effects and number of dead plants) and on day 21 by shoot height and shoot fresh weight determination. After 21 days no test item related phytotoxic effects were observed for all tested plant species at test concentrations up to 1000 mg/kg DW.
The NOEC values as well as the calculated EC-values with confidence ranges are given in the tables below.

- Executive summary:
The phytotoxicity of the test item C18/C18 unsatd.-Glucamide (batch number:SN119/13/3-8) to three terrestrial plant species was determined in a seedling emergence test over a period of 21 days, from 2014 -06 -04 to 2014 -06 -25 according to OECD 208 (July 2006) at Dr.U.Noack-Laboratorien, 31157Sarstedt, Germany.
Test systems were one monocotyledon, oats (Gramineae), and two dicotyledons, rape (Brassicaceae) and soybean (Leguminosae).
The test was conducted with the test concentrations1000 - 500 - 250 - 125 -62.5 mg/kg DW (factor 2).
The test item was incorporated into the soil in which the seeds were sown afterwards. The test containers were bottom watered with nutrient solution as needed. The toxic effects of the test item were determined on day 7, 14 and 21 by visual observations (number of emerged seedlings and phytotoxic effects) and on day 21 by shoot height and shoot fresh weight determination.
After 21 days no test item related phytotoxic effects were determined for all tested plant species up to the test concentration 1000 mg/kg DW (section12.3.3).
The statistically calculated NOEC values, as well as thecalculated EC10-, EC25- and EC50-values, are summarized in the tables below.
The results of the control for all plant species met the required validity criteria. Therefore, the test is considered to be valid.
