Safety and quality have always been top priorities for Vermont apple growers. IPM is an important component in producing high quality fruit and in reducing pesticide risks in apple production.

We are in the process of examining Organic IPM using organically approved materials, reviewed and approved by the Organic Materials Review Institute (OMRI) and the state's certifying agency. Thresholds used in standard IPM orchards should be viewed as provisionary in organic apple orchards until more experience is gained.

The Organic IPM checklist was developed to serve as a quick reminder of IPM considerations during different times of the year. As such, it does not go into details. It is a "work-in-progress" and will be modified as the authors gain more experience in organic apple production. Details can be found in other publications.

It is the grower's responsibility to ensure that any crop production practice or material used in the orchard is acceptable in their particular state's organic certification program.

Some materials deemed organically acceptable on the National List may not be acceptable in some states. Contact your certifier to know what is acceptable and to ensure compliance with regulations in your state.
