Abstract:: Three kinds of commonly used acaricides spirotetramat，spirodiclofen diester，etoxazole were used as test materials，their effects against the Panonychus ulmi Koch in field were studied by using randomized block design.The results indicated that the rapidly availability and persistence of 20% spirodiclofen diester and 22.4% spirotetramat suspending agent were good whether they were single dose or mixed with other pesticides.The rapidly availability was very poor when 110 g?L-1 etoxazole suspending agent used alone，and it could not rapidly reduce mites density.It needed to be used with other readily available acaricides.
