Cicadas are not good for our roses. We reveal how to recognize the pests and how to fight rose leafhoppers naturally. Are you wondering why some of the leaves of your roses show an unusual pattern of light, small spots that eventually merge into white areas? Rose leafhoppers ( Edwardsiana rosae<\/em> ) leave such patterns when they attack roses. We will show you how you can recognize an infestation and fight it naturally.<\/p>\n

How to recognize cicadas on roses<\/h2>\n

The rose leafhopper itself is an elongated insect about three millimeters in size that is white to yellowish-green in color. Rose leaf hoppers usually sit on the underside of the leaves and are therefore difficult to see. They pierce individual cells of the leaves and suck them out. These sucked-out cells fill with air and then appear white on the leaf surface.<\/p>\n

This is why many small white spots appear on the top of the leaf on rose petals that have been infected by the rose leafhoppers. This is the best way to recognize cicadas on roses. The sharp edges of these small points or surfaces are characteristic. Initially, the spots are mainly seen on the leaf veins and then spread over the leaf.<\/p>\n

An infestation by spider mites ( Tetranychidae<\/em> ) can cause similar symptoms, but the webs typical of spider mites are missing in a cicada infestation. In addition, the adult cicadas jump away when touching the infected leaf, which is also a good differentiation from a spider mite infestation. Larval skins of the cicada larvae on the underside of the leaf also help to identify a cicada infestation.<\/p>\n

If the infestation is severe, the leaves dry up and fall off prematurely. Rose leaf hoppers occur mainly in sunny and dry locations from May onwards.<\/p>\n

Tip: If you have climbing roses in your garden in addition to hybrid tea roses, check the climbing roses in particular. An infestation by the rose leafhopper can usually first be recognized by the climbing rose.<\/div><\/div>\n

So you can fight rose leafhoppers of course<\/h2>\n

Often an infestation by the rose leafhopper is not noticed. Unfortunately, the animal transmits the rose mosaic virus by suckling on different plants. This virus also weakens your rose after the leafhoppers disappear, which is why fighting the rose leafhoppers is recommended. In the case of a slight infestation by rose leafhoppers, a nettle brew can be used, the preparation of which we explain in our article on home remedies against aphids.<\/p>\n

If the stinging nettle brew did not help, you should fight the infestation more effectively. Synthetic and biological pesticides are available on the market for this purpose. Synthetic agents use different active ingredients: acetamiprid, fenpyroximate, and flupyradifuron for example. It is not uncommon for them to be offered in conjunction with oils such as rapeseed oil in order to further improve the effect.<\/p>\n

Some bio-agents are based on pyrethrins. These are isolated from chrysanthemums, but their origin says nothing about their harmfulness: Pyrethrins are extremely toxic to beneficial insects and aquatic organisms. In order to protect beneficial insects and the environment from synthetic and natural poisons, we recommend that you combat rose leafhopper in your home garden with gentler means.<\/p>\n
