What are the common pests of roses
The main pests of roses include red spiders, whiteflies, aphids, and thrips. These pests are extremely harmful to roses, and if not treated promptly, they can cause the plant to die directly. These insects mainly feed on the nutrients inside the flowers, leaves, and branches of roses, so plants affected by these pests will show some adverse symptoms.
1. Red spiders
People who cultivate roses should be aware of the pests that affect them, as this can help roses grow better. Red spiders are probably familiar to many people; they have a strong reproductive ability and can easily be infected in hot and humid environments. This pest causes rose leaves to form webs and develop many spots on the surface.
2. Whiteflies
Whiteflies are also common pests of roses. They mainly feed on nutrients inside the leaves and can breed throughout the year, producing about 8-9 generations annually. If not treated promptly, whiteflies can cause rose leaves to turn yellow and wilt, and in severe cases, lead to the direct death of the plant. The best drug for controlling whiteflies is dinotefuran.
3. Aphids
Aphids are extremely harmful pests that feed on the nutrients in rose buds, tender leaves, and young branches. Their reproductive ability is astonishing, and if not treated promptly, the entire plant can become infested with aphids. The areas where aphids have fed will turn black, and the incidence rate is highest during the summer and autumn seasons.
4. Thrips
Thrips mainly feed on the sap in rose flowers. Roses affected by thrips are prone to flower drop, and some roses in the bud stage may fall before blooming. These pests are very small and can fly or run. Affected plants will have their leaves turn yellow, and various parts will grow abnormally, with severe cases leading to a stop in rose growth.
