Damping off covers a range of fungi that cause plant death in establishing pasture. Causal pathogens are Pythium and Fusarium spp.

 

Species affected

Ryegrass, clover.

 

Identification

Young plants wilt and die from lesions at and below soil level.

 

Spread

Infection is common in autumn and winter particulary during cold wet weather. Fungal spores are widespread in the soil and can become very active when climatic conditions are suitable.

 

Prevention and management

All the fungi are soil-borne and spores can build up over successive years. AGRICOTE Grass seed treatment provides early control.
