Spider Mites

Spider mites are persistent pests of numerous specialty ornamental crops, such as hibiscus, palms, viburnum, orchids, marigold, dracaena, and roses. These pests cause a significant reduction in marketable product quality and yield. Heavy infestations may also cause leaf drop and, ultimately, the death of entire plants.
