Sooty mold – Symptoms and treatment

sooty-mold-plants

Sooty mold can be found on the organs of the plants along with the presence of sweet excrements, “honeydew”, which appear as a result of pests attacks. Sooty mold manifests on the branches, leaves and fruits of stone fruits, pome fruits, indoor or outdoor ornamental plants, flowers, vegetables, etc.



Symptoms

On the organs of plants attacked by pests that leave sweet excrements appears a blackish layer, similar to soot. This layer represents the fructification of the Capnodium mushroom and it forms on the surface of the organs covered with these excrements, which represent a sugary substance. Insects that secrete sweet excrements can be aphids, cicadas, greenhouse whiteflies, European fruit lecanium or wooly apple aphids.

The plants are indirectly affected by sooty mold, since the layer formed prevents the photosynthesis process, a process indispensable to plants. Decreased photosynthesis reduces the development and fruiting of the plants. Sooty mold also leads to an unpleasant aspect of the plants, thus decreasing the value of ornamental plants and the fruits are difficult to sell.
