Phyllosticta sojaecola is a plant pathogen infecting soybean.
Hosts and symptoms
[edit]Causes Phyllosticta Leaf Spot on soybeans. Forms circular lesions with reddish-brown borders and light brown center. The center of the lesion will drop out over time. Visible pycnidia can be seen in older lesions.[1] A common consequence of infection is reduced yield from the damaged leaves.
Disease cycle
[edit]Phyllosticta sojicola and all other members of the Phyllosticta genus are ascomycete fungi, with pathogenic species forming spots on leaves and some fruit.[2] Phyllosticta sojicola emerges from infected plant debris in spring and spread by wind and rain-splash onto healthy plants. While the infection method for Phyllosticta sojicola are unknown, other Phyllosticta species are known to infect leaves via an appressorium in a process that requires adequate moisture.[3] Within mature lesions, the fungus forms pycnidia to overwinter and repeat the cycle. Phyllosticta sojicola can also survive on seeds and infect new fields through infected seed.[4]
Environment and management
[edit]Phyllosticta sojicola prefers cool, moist conditions, as pycnidia require moist conditions to germinate.[5] The pathogen can be managed by rotating to non-hosts and using tillage to remove infected residue.[6] As infected seed can transmit the pathogen, seed testing is recommended to prevent introduction of disease.[7]
