<br/><br/> Three essential oil plant extracts, of chamomile; chamomilla recutita (L.), Marjoram; Marjorana hortensis (L.), and Eucalyptus (Eucalyptus sp.) were screened to study their ability for controlling Tetranychus urticae Koch. Different concentrations of essential oil extracts (0.5, 1, 2, 3 and 4%) of C. recultita, M. hortensis and Eucalyptus sp. were used as acaricidal activity against Tetranychus urticae
