Notes:
New methods have been developed
that reduce costs by more than 50 percent while maintaining
effectiveness and reducing environmental impact.
See Reduced
Agent and Area Treatments (RAATs) Brochure.
Pesticide registrations change frequently. As of 2004,
Acephate is no longer registered while Dimilin is registered by EPA
for rangeland grasshopper control.

For blocks of rangeland in the thousands
of acres, aerial application of insecticides provides
one of the most cost-effective methods of grasshopper
management. Research has shown that aerial application
of bait in the form of treated wheat bran can also be
cost effective, especially in environmentally sensitive
areas. (APHIS photo by Mike Sampson.)
