Poplar Tree Diseases

 

Cryptodiaporthe Canker

 

  • Symptoms

    • At first, a few twigs are killed. The fungus spreads rapidly to cause many variously shaped cankers and kill large branches as it does so. Perennial Canker formation leads to leaf Poplar Tree Disease - Cankeryellowing, premature defoliation, and water sprout formation. Green-Brown material filled with spores oozes out of the canker during wet weather and dries to a brown color. When the tree walls off the canker, the bark covering the canker may crack, fall away, and thereby expose inner wood to decay fungi. Trees most susceptible are those under drought or other stress.

 

  • Management

    • Irrigate to prevent drought stress in the late Summer and Autumn. Remove infected trees.

 

Cytospora Canker

 

  • Symptoms

    • Twigs and larger branches die. Brown, circular, sunken cankers form on the bark. During wet weather yellowish threads of spores ooze out of fruiting structures in the canker.

 

  • Management

    • Remove infected branches cutting well below the canker. Remove severely infected trees.
