为明确18%毒·氟防治地下害虫的最佳使用剂量,研究了18%毒·氟CS对玉米地下害虫的防治效果。结果表明:除了18%毒·氟CS药种比1∶50处理抑制玉米生长外,其它药剂处理对玉米生长没有影响。18%毒·氟CS药种比1∶100处理玉米被害率最低,对玉米地下害虫防治效果最好,为94.34%,极显著高于其它处理,其产量最高,比空白对照增产15.19%,比对照药剂60%吡虫啉PS处理增产6.05%。因此,18%毒·氟CS防治玉米地下害虫最佳使用量为药种比1∶100。
In order to clarify the optimal dosage of 18% poison and fluoride to control underground pests, the control effect of 18% toxic and fluorine CS on underground pests of corn was studied. The results showed that except for 18% of the poisoning, the treatment with fluorocarbon CS inhibited the growth of maize at a ratio of 1:50, and the other treatments had no effect on the growth of maize. The ratio of virulent and fluoro-CS with the ratio of 1: 100 was the lowest. The control effect on the underground pests was 94.34%, which was significantly higher than other treatments. The yield was the highest, 15.19% more than that of the blank control Control agent 60% imidacloprid PS treatment increased yield 6.05%. Therefore, 18% of the toxic fluorine fluoride CS optimal application of underground pests for the drug ratio of 1: 100.
