Abstract: 【Objective】 The test aims to screen out several acaricides which can control tetranychid mite effectively in the sugar beet fields.【Method】A randomized block test was used to investigate the number of tetranychid mite in each plot with seven insecticide treatments and one clear water control. The efficacy of field spraying was investigated by spot sampling on the 3 rd day and 7 rd day after the treatment, the number of tetranychus mites in each treatment area was investigated and the efficacy in controlling tetranychus mites was evaluated.【Result】Seven days after the treatment, the control efficacy to tetranychid mite of 22% avermectin and spirodiclofen SC 4,000 times, 25% azocyclotin WP 10,000 times, 10% avermectin WG 1,500 times, 73% propargite EC 2,000 times and 240 g/L spirodiclofen SC 4,000 times reached up to 93.35%, 93.51%, 93.38%, 91.80% and 89.87%.【Conclusion】5 kinds of acaricides were screened out, which had better control efficacy to tetranychid mite in the sugar beet fields, and their control efficacy was over 89.87% after 7 d. These acaricides are safe to beets and can be used for rotation in the control of sugar beet tetranychid mite.
