The deposition index of acaricide was measured using water-sensitive paper, and the relationship between this index and mite mortality was examined by laboratory and field tests. The acaricide deposition index and mortality of an acaricide-susceptible strain of the Two-Spotted Spider Mite, Tetranychus urticae KOCH were observed in laboratory tests. The results indicate an exponential relationship fenpyroximate. On the other hand, in direct observations using directscarlet liquid, the relationship between the deposition index and the actual deposition of droplets is exponential. In field tests with tebufenpyrad on eggplants, higher deposition indices resulted in higher mortalities of the Kanzawa Spider Mite, T. kanzawai KISHIDA. When the deposition index was 5 or more the mite mortality reached more than 70%. We propose that a deposition index of more than 5 measured by water-sensitive paper is a requisite condition for effective spraying.
