Capnodium is a genus of sooty molds that form black encrustations on plant leaves, flowers, stems, and fruit. It was first circumscribed in 1849 and includes the type species C. salicinum. Capnodium lives on the sugary secretions of plant-feeding insects and reduces plant photosynthesis, resulting in reduced fruit set and fruit fall. Major host plants include mango, citrus, tea, and coffee. Stemphylium solani is a fungal plant pathogen that causes grey leaf spot in tomatoes and leaf blight in alliums and cotton, with symptoms of white and red/purple leaf spots and lesions leading to necrosis.

4. Scientific Classification:
 Kingdom : Fungi
 Division : Ascomycota
 Class : Dothideomycetes
 Order : Capnodiales
 Family : Capnodiaceae
 Genus : Capnodium

5. SYMPTOMS:
 Black encrustation is formed on leaves, flowers, stem and fruit.
 Mycelium is superficial and lives on the sugary secretion of the
plant hoppers.
 Photosynthetic ability is reduced which results in reduced fruit set
and fruit fall.

 Fruit - Honeydew or sooty mould.
 Fruit - reduced size.
Growing point - Honeydew or sooty mould.
Inflorescence - Honeydew or sooty mould.
Leaves - Honeydew or sooty mould.

14. Stemphylium solani:
Stemphylium solani is a plant pathogen fungus in the phylum
Ascomycota.
