The compound also showed a high acaricidal activity against Tetranychus urticae, Tetranychus kanzawai and Rhizoglyphus echinopus and showed a high nematicidal activity against Meloidogyne incognita. Residual activity by foliar spray of TIA-230 was shown to be higher than those of prothiophos, acephate, methomyl, demethylvinphos, chlorpyrifos-methl, dicofol, fenbutatin oxide and cyhexatin. In field tests, the sprays of 0.017% and 0.035% solution of TIA-230 (wettable powder) were highly effective in controlling the damage to cabbage by Spodoptera litura, Mamestra Brassiase, Plutella xylostella, Pieris rapae and Myzus persicae.Originating text in Japanese.Citation: Sato, Yasuo, Kono, Yoshiaki, Nagano, Masayoshi, Manabe, Yukiaki, Oguchi, Hiroaki, Yamamoto, Yasuhiro.
