| Abstract:
Toxicity of several acaricides to Panonychus ulmi, Tetranychus urticae and the predatory mite, Amblyseius longispinosus evaluated using slide dip and leaf dip methods in the laboratory. Fenazaquin was found to be most toxic to both species of mite and this toxicity persisted for 15 days under field conditions. There were differences in acaricide toxicities to different populations of mite showing built up of resistance and differences in the two species of mite. | |
