| Abstract: | Taking 90% Acetochlor,70% Metribnzin,48% Clomazone,72% Metolachlor EC,48% Trifluralin EC and 50% Napropamide as reagents,the weeds in potato field were controlled before seedling emergence with pesticide ready-mixture.The results showed that：all treatment combinations achieved control effects,increased yield and had no phytotoxicity to the potato.The control effect and increasing yield effect of treatment of 90% acetochlor and 70% metribuzin was the best among the 5 treatment combinations.Itsplant control effect was 84.47%~91.90%,fresh weght control effect was 91.75%,and it could increase the yield by 14.57%. |
