Dispersal and Spread
The spores of P. teres are usually carried by wind. Growth of the organism on a host plant causes symptoms including necrosis, senescence and eventually cell death. In countries like Australia, damage from Pyrenophora can have serious economic consequences and reduce farm yields by up to 50%. Host tissue is obtained by penetration of the cell with an appressorium, a bulbous formation produced by the fungus that allows the uptake of nutrients.

Famous quotes containing the word spread:
“none
Thought of the others they would never meet
Or how their lives would all contain this hour.
I thought of London spread out in the sun,
Its postal districts packed like squares of wheat:”
—Philip Larkin (1922–1985)
