Diseases of succulents
Cochineal, aphids and mites can cause significant infestations tosucculent plants, even if grown indoors. Between fungal diseases of succulents we point out the gray mold, the leaf spots and the fumagigne.
Cochineal on succulents
Among the scale insects, the most common to attacksucculent plantsare the cottony and the flocky. In both cases, the infestation shows up with sticky whitish clusters under which the insects hide. Another fearsome cochineal is the "scudetto" one. The symptoms of an infestation by the scudetto cochineal are the small circular and hard encrustations that appear on the fleshy surface of the plant. These incrustations have a reddish-brown color, are hard to the touch.
The scale insects develop more when thesucculent plantsthey are excessively irrigated and are placed in poorly lit environments.
All three types of cochineal, if no treatment is carried out, can lead to the desiccation of the plant.

The treatment of gray mold on succulents must be carried out with specific phytosanitary products based on tebuconazole. If the infestation is minor, you can move the plant to a sunny and airy position, reducing irrigation could limit its development.
Spots on leaves
If you notice round spots on the leaves of your succulents, it is probably the work of a fungus! The spots take on a greyish-brown color and, in the case of an advanced infestation, the area undergoes rot. This fungal disease should be treated with remedies copper based.
Smokiness of succulents
The smokiness is typical of plants already weakened and already tested by aphids and cochineal. In fact, the smoky mushrooms feed on the zuccerini residues produced by aphids and scale insects. The fumaggine manifests itself with blackish and dusty formations. They can cause deformation of the green parts and serious damage to the plant. How is smoking on succulent plants treated? THE natural remedies they can be very effective: try spraying a solution of Marseille soap and water on the affected area.
