Question from Raphaël

<< Bonjour, j'ai un problème avec l'une de mes fleurs, un lys asiatique. Les feuilles se désintègrent : elles deviennent marron puis très fines, et finissent par faner. Je pense que ce sont les "petits" de l'insecte rouge qu'on voit sur la photo, il y a ces insectes uniquement sur les lys. Ma plante se trouve à l'extérieur, au soleil. J'ai enlevé au jet toutes les larves noires. >>

Auscultation and diagnosis

The Asian lily presented to Frédéric Marque suffered a fairly widespread scourge: the colonization of the plant by small black clusters, and adult red insects. The latter are called lily beetles, while the former appear to be small larvae that hide under their excrement, and take pleasure in drying the leaves one after the other. This colonization is allowed thanks to the reproductive cycle of insects, which new generations take over to weaken the plant.

Answer: use insecticide

Faced with such an attack, only the heavy solution is possible: insecticides. These will drive out the insects from the plant, and allow it to resume normal life. You too, ask your questions at The Plant Clinic!
