Apple Powdery Mildew

Symptoms: Young leaves breaking from buds which were infected during the previous year will show symptoms. Leaves are covered with a white growth.

Cause: This is caused by the fungus Podosphaera leucotricha. It overwinters in apple buds or on young stem growth - which can be seen as silvery white patches on the bark.

Control: Keep the plants well watered to prevent development. Mulch to preseve soil moisture. Prune out severely affected stems. Ensure the tree is pruned to ensure good air circulation.
