• Plant a disease resistant tree such as
'Liberty.' These apples do not get the apple scab disease.
• Plant a dwarf or semi-dwarf tree
• Plant tree in early fall or spring in a sunny
location with plenty of air circulation
• Apply insecticide Imidan (phosmet) when
all the flower petals have fallen (generally late May) and again
10-14 days later to control the plum
curculio, European apple sawfly, leafrollers, and codling moth.
• Hang sticky red spheres in trees at the end
of June Use 1-6 traps per tree, depending on tree size. Ideally use
1 trap per 150 fruit. Set traps at approximately head-height in the
outer portion of tree canopy where there are plenty of developing
fruits nearby. Remove all fruit and foliage within 1-2 feet of the
trap. Traps can be purchased at garden centers.
• Pick up and remove dropped apples, and rake and
destroy apple leaves in the fall. If you already have
disease-susceptible trees planted, spray a fungicide such as Captan
every 7 days from late April to early June.

sources of disease resistant fruit trees, see "Home Tree and Small
Fruit Pest Management Guide," or visit the URI Apple IPM website at
