Roses (Rosa species) are susceptible to a number of pests, diseases and disorders. Many of the problems affecting roses are seasonal and climatic.[1] Some varieties of roses are naturally more resistant or immune than others to certain pests and diseases. Cultivation requirements of individual rose species and cultivars, when observed, often assist in the prevention of pests, diseases and disorders.[2]
