They were evaluated under laboratory conditions using onion (Allium cepa L.) as a test material. The phytotoxic effects on root were determined after 7th days. Surfactants used in study were tested at three different surfactant concentrations, 5.00, 2.50 and 1.25 g/L (w/v) concentrations. The phytotoxicity results were based on the effective concentration that reduced root growth I I by 50 % (EC50). Some differences were observed between the effects of three types of surfactants. Stimulatory effects only occurred in I Triton X-405 while inhibitory effects occured in Triton X-100 and Triton X-114 at all concentrations. It was observed that inhibitory effects increased with increasing concentrations of Triton X-114 and Triton X-100.eninfo:eu-repo/semantics/closedAccessOnionEffectTriton X-100Triton X-114Triton X-405Non-Ionic SurfactantAdjuvantsToxicityEfficacyGrowthConference Object241257465748Q4WOS:0003107712000892-s2.0-84867266847Q4
