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]
An aphid infestation can ruin a garden. Learn what causes aphids and how to identify, kill, and control them naturally for healthy plants with no aphid holes.
Macrosiphum rosae, the rose aphid, is a species of sap-sucking aphids in the subfamily Aphidinae.

Acephate is an organophosphate foliar and soil insecticide of moderate persistence with residual systemic activity of about 10–15 days at the recommended use rate. It is used primarily for control of aphids, including resistant species, in vegetables (e.g. potatoes, carrots, greenhouse tomatoes, and lettuce) and in horticulture (e.g. on roses and greenhouse ornamentals).
Aphids are repelled by strongly aromatic plants such as lavender, marigolds, garlic and mint. Plant these among your more vulnerable plants. Using trap plants is a different approach.

This occurs in, for example, the life cycle of the rose aphid (Macrosiphum rosae), which may be considered typical of the family.
