Therefore, how to master the application technology, determine the field of control, and determine the appropriate period and frequency of pesticide application in order to use pesticides economically and efficiently is an important issue for the current pesticide to control rice stem borers. Now the author’s work results over the years to organize as follows, for reference. One, six hundred sixty-six control borer in order to poison killer insects in the past on the sixty-six governance borer have two different views: Some people advocate to kill moths; others advocate to poison
