为了有效控制甘草重大害虫—甘草胭脂蚧,本文开展了甘草胭脂蚧药剂防治与农业防治协调控制技术研究。结果表明,甘草不同种植深度对甘草胭脂蚧的寄生和扩散影响较大,10cm深时甘草胭脂蚧寄生数量最多,为14.8头/株,扩散距离最远,为18.6cm,其次为15cm、20cm深,25cm深甘草胭脂蚧寄生数量、扩散距离均显著少于、短于10cm、15cm深的,分别为2.8头/株和10.4cm。药剂防治结果表明,药后15d,鱼藤酮对甘草胭脂蚧的防效最好,校正虫口减退率可达94.13%,其次为啶虫脒、烟碱,吡虫啉相对较低;药后30d,鱼藤酮的防效为60.56%,持效期较长。可见,甘草深种植结合有效药剂防治,对甘草胭脂蚧起到很好地协调控制作用。
In order to effectively control licorice major pest - licorice rouge, this paper carried out a licorice rouge scale coordination of pesticide control and prevention and control of agricultural technology research. The results showed that the effects of different planting depths on the parasitism and spread of licorice mackerel were significant. The number of parasitism and spread of licorice mackerel at 10cm depth was the highest (14.8 pigs per plant), the spread was the longest, 18.6cm, followed by 15cm and 20cm , 25cm deep licorice carmine scale parasitic numbers, the proliferation distance were significantly less than 10cm, 15cm deep, respectively 2.8 head / plant and 10.4cm. Pharmacological control results showed that Rotenone had the best control effect on Rhizoctonia solani 15 days after drug administration, with a corrected rate of 94.13%, followed by acetaminophen, nicotine and imidacloprid. After 30 days, rotenone Effective for 60.56%, longer duration. Visible, licorice deep planting combined with effective agent control, play a good role in the coordination and control of licorice rouge.
