Question from the user

<< Bonjour, je possède un lierre et un ficus qui présentent des taches et de la poussière sur les feuilles. La maladie semble avoir débuté sur une plante et s'être transmise à d'autres. Les plantes sont placées sur une petite terrasse intérieure dans une zone ombragée. J'ai d'ores et déjà essayé d'utiliser un spray anti-pucerons mais rien n'y a fait. >>

Auscultation and diagnosis

Both plants have cottony clumps and dust on the leaves. We also know that symptoms have spread over time. There is therefore no doubt, we are in the presence of a colonization of insects. The ones that create this black dust on the leaves are scale insects. The latter hide behind shells and give off sugary juices on which fungi called sooty mold develop.

Some recommendations

The mealybug is an insect that is difficult to eradicate because it manages to repel water. This is why it is necessary to turn more to oily products in order to create a film around the insect which will suffocate it. Once the mealybugs are removed, the black dust on the leaves will disappear on both plants on its own. If it persists, you can wash the leaves with a damp cloth.
