Guidelines provided by OECD and EPPO allow the use of data obtained in greenhouse experiments in the risk assessment for pesticides to non-target terrestrial plants in the field. The present study was undertaken to investigate the predictability of effects on field-grown plants using greenhouse data. In addition, the influence of plant development stage on plant sensitivity and herbicide efficacy, the influence of the surrounding vegetation on individual plant sensitivity and of sublethal herbicide doses on the biomass, recovery and reproduction of non-crop plants was studied. Results show that in the future, it might well be possible to translate results from greenhouse experiments to field situations, given sufficient experimental data. The results also suggest consequences at the population level. Even when only marginal effects on the biomass of non-target plants are expected, their seed production and thereby survival at the population level may be negatively affected.
经济合作与发展组织（OECD）和欧洲和地中海植物保护组织（EPPO）提供的指南允许在农药对田间非靶标陆生植物的风险评估中使用温室试验获得的数据。本研究旨在利用温室数据调查对田间种植植物影响的可预测性。此外，还研究了植物发育阶段对植物敏感性和除草剂药效的影响、周围植被对单株植物敏感性的影响以及除草剂亚致死剂量对非作物植物生物量、恢复能力和繁殖的影响。结果表明，在未来，如果有足够的实验数据，很有可能将温室试验的结果转化为田间情况。结果还表明了在种群水平上的后果。即使预计对非靶标植物生物量只有轻微影响，其种子产量以及在种群水平上的存活可能会受到负面影响。
