A pesticide is defined as any substance or mixture of substances intended for preventing, destroying, repelling or mitigating any pest, or intended for use as a plant regulator, defoliant or desiccant.

All university personnel (includes faculty members, staff members, students, and any other university- affiliated individuals) who label, store, use, transport, dispose of, or clean up spills of pesticides are responsible for adhering to federal and state regulations, as well as Cornell Health & Safety Policy 8.6.

It is essential that teaching, research, extension, exterior ground maintenance and structural pest control involving pesticide use be conducted properly and legally for the protection of the pesticide applicator, other employees, staff, students, public health, and the environment.

The responsibility for ensuring that all work with pesticides at Cornell is conducted properly and legally rests on the individual user.
