An effective method using liquid chromatography–tandem mass spectrometry (LC–MS/MS) was developed and optimized to obtain a complete separation of five representative plant growth regulators (PGRs) [gibberellic acid, 2,4-dichlorophenoxyacetic acid (2,4-D), thidiazuron, forchlorfenuron, and paclobutr...
