Scope
This standard specifies the method for evaluating the potential effects of test substances on the vegetative vigour of the above-ground parts of terrestrial plants, excluding all chronic effects on plants and effects on reproduction (e.g., seed setting, flowering, fruit maturation). This standard is applicable to general chemical substances, crop protection agents or pesticides.
本标准规定了评价受试物对陆生植物露出地面部分生长活力的潜在影响的方法，不包括对植物的所有慢性效应及对繁殖的影响(例如结实、开花、果实成熟)。本标准适用于一般化学物质、农作物保护剂或农药。

It provides critical data for environmental risk assessment of chemicals, ensuring the safe use of pesticides and other substances in agriculture.
环境毒理学实验室、化学品登记机构以及农药生产企业使用该标准来评估化学物质对陆生植物地上部分生长活力的潜在影响。该标准通过标准化的试验方法，为化学品环境风险评估提供关键数据，确保农药等化学物质在农业生产中的安全使用。
AI Summary AI generated
This standard specifies a test method for evaluating the potential effects of chemicals on the vegetative vigour of above-ground parts of terrestrial plants, applicable to general chemical substances and pesticides. After plants reach the 2-4 true leaf stage, the test substance is sprayed, and over 21-28 days, biomass, height, and visible damage are measured to calculate effect concentrations (ECx) or no-observed-effect concentrations (NOEC). The standard details test design, conditions, data processing, and reporting requirements, providing a standardized procedure for environmental risk assessment of chemicals.
本标准规定了评价化学品对陆生植物地上部分生长活力潜在影响的试验方法，适用于一般化学物质和农药。试验在植物长出2-4片真叶后喷洒受试物，通过21-28天的观察，测量生物量、高度及可见损伤，计算效应浓度(ECx)或无效应浓度(NOEC)。标准详细规定了试验设计、条件、数据处理和报告要求，为化学品环境风险评估提供标准化程序。

本标准规定了评价受试物对陆生植物露出地面部分生长活力的潜在影响的方法，不包括对植物的所有慢性效应及对繁殖的影响(例如结实、开花、果实成熟)。
本标准适用于一般化学物质、农作物保护剂或农药。
受试植物从种子到长出2片～4片真叶期后，将受试物按适当的比率喷洒到植株及其叶子表面。
在用药后21 d～28 d的试验间隔中(对于附录C中列出的10种植物，试验周期为21 d)，以未喷洒受试物的植株为对照，在不同的间隔时间点，评价受试植物的生长活力。
试验结束时测量幼苗的干重或鲜重。
This standard specifies the method for evaluating the potential effects of test substances on the vegetative vigour of the above-ground parts of terrestrial plants, excluding all chronic effects on plants and effects on reproduction (e.g., seed setting, flowering, fruit maturation).
This standard is applicable to general chemical substances, crop protection agents or pesticides.
After the test plants have grown from seeds to the stage of 2 to 4 true leaves, the test substance is sprayed onto the plants and their leaf surfaces at an appropriate rate.
During the test interval of 21 d to 28 d after application (for the 10 plant species listed in Annex C, the test period is 21 d), the vegetative vigour of the test plants is evaluated at different time intervals, using plants not sprayed with the test substance as controls.
At the end of the test, the dry weight or fresh weight of the seedlings is measured.
