• Biotechnology, specifically Bt hybrids of corn,
  is beneficial for farmers
• Increased yields
• Decreased pesticide use/cost
• Less air / water / soil pollution
• Cut production costs

In Defense of Bt Corn

• The Bt toxin as a plant pesticide in corn has no
  known or foreseeable human health hazards (U.S.
  EPA 1995).
• Bt corn was not found to adversely effect
  non-pest insects

Consequences of a moratorium

• Loss of competitiveness with other states
• Loss of revenue for farmer
• Closing of domestic markets
• Loss of international markets
• Lower yields nationwide
• Higher prices for consumers
• Higher production costs for farmers

• Impact of Bt corn on Monarch butterflies is
  negligible (Sears, 2001)
• Between several states and Canada
• Two year long study
• Published in Proceedings of the National Academy
  of Sciences

Results - Pollen count needed to kill larvae
1000 grains/square cm - Pollen count
found 170 grains/square cm - Only dangerous
strain (Bt 176), phased out by 2003

• Grain Benefits of Bt corn (Monsanto 2001)
• - Reduces insect damage to ears by 96
• - Reduces mold in grain
• - Mold causes fumonisin, a toxic mycotoxin
• - YieldGard corn was found to reduce fumonisin
  by 90-93
• - Prevents grain eating larvae by 70-80

• Insect resistance management
• EPA and Corporate seed agreements
• 100 ft. buffer zone
• Non-Bt corn refuge is required on at least 20
  percent of corn acres
• Refuge provides non-resistant mates
• Mating between resistant and non-resistant
  moths/borers dilutes resulting resistance
• Prevents loss of Bt corn as an option for insect
  control

• Environmental Benefits of Bt
• - Reduces need to plow
• - Decreases erosion of topsoil
• - Decreases air, soil, and water pollution
• - Viable alternative to harmful pesticides

- This figure demonstrates the decreasing trend
in herbicide use due to Bt hybrids. - A small
increase in glyphosate can be attributed to the
introduction of a generic brand.

• Farmer Benefits
• - Reduces labor costs
• - Reduces number of trips through fields
• - Reduction in fuel consumption/spillage
• - Increases yield per acre
