Field tests of insecticides for spruce budworm control have been run

annually since 1974 in Maine. The goal is to provide data for registration

of new insecticides or new¡ formulations of presently-registered insecticides,

or in some cases, the goal is to refine the recommended dosage to the

least amount which will produce satisfactory results.

Economic and environmental benefits from reducing dosages are obvious.

There are similar benefits derived from registering new chemicals. New

registrations provide for competitive bidding in the purchase of insecticide

and allow assignment of particular chemicals to particular areas where there

are special environmental considerations.
