A leafhopper(cicada) is not good for our roses. We reveal how to recognize the pests and how to fight Leafhopper On Roses in a natural way. Do you wonder why some leaves of your roses show an unusual pattern of bright little spots that eventually merge into white areas? Leafhopper On Roses (Edwardsiana rosae) leaves such patterns when they infest roses. We will show you how to recognize an infestation and fight it naturally.
How To Recognize Leafhopper On Roses
The Leafhopper on roses itself is an approximately three-millimeter small elongated insect, which is white to yellowish-green colored. Leafhopper usually sits on the underside of the leaves and are therefore difficult to recognize.
They bite individual cells of the leaves and suck them out. These sucked out cells fill with air and appear white on the leaf surface. Therefore, rose petals infested by the Edwardsiana rosae show many small white spots on the upper side of the leaf.
This is the best way to recognize Leafhopper on roses. Characteristic are the sharp edges of these small dots or areas. Initially, the spots are mainly visible on the veins of the leaves and then spread over the leaf. In Central Europe, the Leafhopper on roses passes through two generations with the following sequence:
|October of the previous year||April||May/June||June||August||October|
|Development status||Eggs||Larva||Adult animals migrate partially||Adult animals lay eggs||Adult animals lay eggs for overwintering|
|Generation||Generation 1||Generation 1||Generation 1||Generation 2||Generation 2|
Spider mite infestation (Tetranychidae) can cause similar symptoms, but the webs typical of spider mites are missing in a Leafhopper infestation. In addition, the adult cicadas jump away when touching the infested leaf, which is also a good differentiation from a spider mite infestation.
Larval skins of the Leafhopper larvae on the underside of the leaf also help to identify a cicada infestation. In case of a heavy infestation, the leaves dry up and fall off early. The Leafhopper on roses occurs mainly in sunny and dry locations from May onwards.
How You Can Fight Leafhopper On Roses Naturally
Often an infestation by the Leafhopper on roses is not noticed. Unfortunately, the little animal transmits the rose mosaic virus by sucking on various plants.
This virus also weakens your rose after the cicada has disappeared, which is why fighting the Leafhopper on roses is recommended. In case of a slight infestation by cicadas, a nettle broth can be used, the preparation of which we explain in our article on household remedies against aphids.
If the stinging nettle broth does not help, you should fight the infestation more effectively. Synthetic and biological pesticides are available on the market.
Synthetic agents use different active ingredients: Acetamiprid, Fenpyroximat, and Flupyradifuron for example. They are often offered in combination with oils such as rapeseed oil to further improve their effectiveness. Some bio-agents are based on pyrethrins.
These are isolated from chrysanthemums, but their origin says nothing about their harmfulness: Pyrethrins are highly toxic to beneficial organisms and water organisms. In order to protect beneficial organisms and the environment from synthetic and natural toxins, we recommend that you combat Leafhopper on roses in your home garden with more gentle products.
Preparations based on neem are particularly effective and environmentally friendly in combating Leafhopper on roses. Neem preparations are made from the seeds of the Neem tree and the active ingredient Azadirachtin is absorbed by the Leafhopper when they suck.
The small insects lose their appetite within a few hours. In addition, the development of the larvae is disturbed, which is why ultimately all generations of Leafhopper on the plant suffer damage and die.
