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.

6. SYMPTOMS ( Capnodium citri ) Fruit - Honeydew or sooty mould. Fruit - reduced size. Growing point - Honeydew or sooty mould. Inflorescence - Honeydew or sooty mould. Leaves - Honeydew or sooty mould.

13. Stemphylium: SCIENTIFIC CLASSIFICATION Kingdom : Fungi Division : Ascomycota Class : Dothideomycetes Order : Pleosporomycetidae Family : Pleosporales Genus : Stemphylium

14. Stemphylium solani : Stemphylium solani is a plant pathogen fungus in the phylum A scomycota . It causes grey leaf spot in tomatoes and leaf blight in Alliums and Cotton. Symptoms include white spots on leaves and stems that progress to sunken red or purple lesions and finally leaf necrosis.
