Abstract: A new standard for measuring acaricide virulence that can be applied to all kinds of acaricide is proposed to rectify the limitations of the current standard. An example of the application of the new standard is provided in which the Potter spray method was used to test acaricide virulence on 4 different stages of Tetranychus urticae Koch raised on groundnut leaves in a laboratory. The results indicate that the proposed new standard can not only accurately evaluate the effectiveness of acaricides but is also practical to use.
