Abstract: The present disclosure relates to a sprout inhibitor composition containing dihydrocarvyl acetate and use thereof. The sprout inhibitor composition contains the active ingredient dihydrocarvyl acetate or isomers thereof. In sprout inhibition tests for the sprout inhibitor in tobacco and potato, when the dosage of the active ingredient is equivalent to carvone, the sprout inhibitor exhibits a significantly better sprout inhibition effect than that of carvone. The sprout inhibitor provided by the present disclosure is effective on tobacco and potato plants in low dosage with long effective duration. Moreover, no phytotoxicity of the sprout inhibitor on the tobacco or the potato is found within the application range.
