Figure 3. The percentage of each size category of orchard that used 0, 1 to 2, 3 to 5, or 6 to 10 IPM 

 practices. Very small = 0-5 acres, small = 5.1-20 acres, medium = 20.1 to 50 acres, and large =

cost of managing such key pests as summer diseases, 

 plum curculio, apple maggot, and mites, and the like- 

 lihood that environmental advocates and regulators

The Tree Fruit Team will continue its efforts, alone 

 and in collaboration with other university special- 

 ists and the private sector, to better understand 

 grower needs relative to IPM, and work diligently 

 to develop and demonstrate apple pest management 

 and production systems for the 21st century.
