多效唑是一种植物生长调节剂，具有延缓植物生长，抑制茎秆伸长，缩短节间、促进植物分蘖、增加植物抗逆性能，提高产量等效果。多效唑适用于水稻、麦类、花生、果树、烟草、油菜、大豆、花卉、草坪等作物，使用效果显著。
多效唑是上世纪80年代研制成功的三唑类植物生长调节剂，是内源赤霉素合成的抑制剂。 也可提高水稻吲哚乙酸氧化酶的活性，降低稻苗内源IAA的水平。明显减弱稻 苗顶端生长优势，促进侧芽(分蘖)滋生。秧苗外观表现矮壮多蘖，叶色浓绿。 根系发达。解剖学研究表明，多效唑可使稻苗根、叶鞘、叶的细胞变小，各器官的细胞层数增加。示踪分析表明，水稻种子、叶、根部都能吸收多效唑。叶片吸收的多效唑大部分滞留在吸收部分，很少向外运输。多效唑低浓度增进稻苗叶片的光合效率；高浓度抑制光合效率，提高根系呼吸强度，降低地上部分呼吸强度，提高叶片气孔抗阻，降低叶面蒸腾作用。
