In order to study the optimal period to spray, acetochlor+prometryn 40%EC was used as a soil treatment with a dosage of 3 750 mL/hm2, and sprayed in four different periods. The test results showed that the control effects on weeds were the best when sprayed acetochlor+prometryn 40%EC during the 14th-21th days after sowing. The herbicide was safe to potato and potato plant growth whenever it was sprayed before seedling.
