Do not spray for mites on a preventative basis. Rotate acaricides to delay resistance. Savey may be applied at the rate of 6.0 oz/A under intense population pressure. Do not apply each acaricide more than twice per season. See Table on REI and PHI.  Predatory mites (Amblyseius fallacis) are available commercially; these have been used effectively. Avoid use of Sevin, Brigade and Danitol if predatory mites are used. Consult distributors on release rates of predators.
