The invention discloses a composition for preventing and treating celery early blight and a preparation method therefor. The composition contains the following raw materials in parts by weight: 20-30 parts of fenthion, 10-20 parts of Cryogenine, 130-150 parts of glycerol, 350-370 parts of water and 6-8 parts of synergists, i.e., pentaerythritol ester and sodium hyaluronate, wherein the ratio (in parts by weight) of pentaerythritol ester to sodium hyaluronate is (5 to 7): 1. The composition provided by the invention can be used for preventing and treating the celery early blight and can be developed into pesticides for preventing and treating the celery early blight; and the control efficiency is related to the ratio (in parts by weight) of pentaerythritol ester and sodium hyaluronate, i.e., the synergists in the raw materials and is the best when the ratio (in parts by weight) of pentaerythritol ester to sodium hyaluronate is (5 to 7): 1. Furthermore, the composition provided by the invention is low in sprayi
