Spider mites are considered to be the most important invertebrate pests of commercial field-grown rose plants, but sampling methods and treatment thresholds have been subjective. This study shows that roses exhibit a higher tolerance for spider mites than previously thought. Quality rose plants were produced with fewer acaricide treatmentsby using a rapid presence/absence field sampling method and treatment thresholds for spider mites.
