Red spider mite
Red Spider Mites breed rapidly under warm conditions and there are strains of this pest that have gained resistance to certain pesticides. The incidence of red spider mite can be more of a problem on roses that are grown in a sheltered, sunny site or on those grown against a sunny wall.
Cultural measure: Remove affected leaves at first signs of damage. Keep plants moist at all times and spray the plant, and surrounding environment regularly with a fine misting of water. Red Spider Mite do not like damp or humid conditions. Discard badly affected plants.
