Introduction
With the applicability of OECD guidelines for testing of chemicals and scientific progress and management of the use will be revised periodically proofreading. This standard
OECD208 [1], based on the revised standard, which aims to evaluate the test substance on terrestrial plants out of the ground portion of the potential growth activity
influences. The test itself does not include all the chronic effects and reproductive effects on plants (eg seed, flowering, fruit ripening). Should be considered
Nature of exposure conditions (usage) of the test substance and the test substance in order to ensure the use of appropriate test methods. This standard applies to general chemicals
Quality, biocidal agents and pesticides (also known as plant protection agents or pesticides). Standard is OECD208 [1-2] as well as other existing methods [3-8] as
Developed on the basis, also referred to other plant trial-related literature [9-12].
Chemicals terrestrial plant growth vigor test
1 Scope
This standard specifies the evaluation of the potential impact of the test substance is exposed on the surface portion of the growth vigor of terrestrial plants method, does not include plants
All chronic effects and reproductive effects (such as strong, flowering, fruit ripening).
This standard applies to general chemicals, crop protection agents or pesticides.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Crop protection agents or pesticides cropprotectionproducts (CPPs) orplantprotectionproduct (PPPs) orpes-
ticides
Having particular biological activity, specifically for protecting crops against pathogens (such as fungi, insects, weeds) against the substance.
2.2
Effect or effects concentration ratio xfectconcentrationorxfectrate, ECx, ERx
Relative to the control group, at the end of the observation x% of the affected during concentration or the ratio (e.g., weight decreased aboveground plant, plant survival
Mesh, or the appearance of plant damage by 25% or 50% concentration or ratio, respectively, EC25/ER25 or EC50/ER50).
2.3
Bud emergence
Coleoptile or cotyledon exposed soil surface.
2.4
Preparation formulation
Formulated commercial product containing the active ingredient, known as the final product or the end product.
2.5
Lowest observed effect lowestobservedeffectconcentration, LOEC
It can be observed in the lowest concentration effect of the test substance. In this test, compared with the control, within a given exposure time, which corresponds to
LOEC, a significant effect (p < 0.05) a statistically, but this value is higher than the NOEC values.
2.6
Non-target plants non-targetplants
Plants outside the target range of plants, in terms of the pesticide, usually refers to the area outside of the processing plant.
2.7
No observed effect concentration noobservedeffectconcentration, NOEC
The highest concentration was observed less effect. In this test, the highest concentration was not observed effect is relative to the entire course of the experiment
For the control of a statistically significant (p < 0.05).
2.8
Phytotoxicity phytotoxicity
(By measurement or observation) plant caused by the substance found in abnormal appearance and growth for damage.
