| Abstract: | Four inner-absorbed insecticides which were omethoate, phorate, Yangleqingju, Jin-dan and four methods which were spraying drug on the trunk, spraying drug after pricking bark, binding up after pricking around and binding up after husking the bark were used to control the Cryptorrhynchus Lapathi L. . The results showed that the controlling effect of omethoate and jindan on the insect which were below the trunk of 2 m could reach 95. 13 % and 94. 31 % , better than that of others . The method of spraying drug after pricking had the best effect which could reach 97.23% . The average effect of omethoate, Jindan or binding up after husking the bark on the Cryptorrhynchus lapathi L. over the trunk of 2 m could reach more than 90 % . |
