The effects of three doses of Spirodiclofen SC 240 in comparison with three registered acaricides on citrus rust mite in western part of Mazandaran province during period of 2003-2004 studied. The BCR design was used to assign four replications of seven treatments (Spirodiclofen SC 240 at doses 0.1, 0.18 and 0.27 millilitre in 1000cc water, Fenproximate, Pyridaben, Abamectin) including an untreated check plot. Twenty treated fruits from each treatment and number of alive CRM counted under stereo microscope, one day before and three, seven, 14 and 25 days after acaricides application accordingly. The percentage of mortality of immature CRM population indicated that Spirodiclofen of 0.27 percent had maximum control. The effect of all treatments was maximum in 3rd day of the sampling, but mortality rate increased with the extent of interval period. The envidor 0.27 percent due to lower doses among the registered acaricides in Iran and because of the higher efficiency with sustainable effect can be recommended for control of CRM in Mazandaran province.
