Why dicamba?
Regulatory status
Use in weed control programs
Stewardship
BOLT™ technology
• More options for weed control
• Zero-­‐day plantback to DuPont™ LeadOff® herbicide
• Rotational flexibility after DuPont™ Finesse® cereal and fallow herbicide
Why dicamba?
Benefits of glyphosate + dicamba weed control program in soybeans:
• Very broad spectrum control of grass and broadleaf weeds, including glyphosate-­‐resistant weeds
• Less spray volume and wider window of application compared to a LibertyLink® system
• Systemic activity within the plant – kills roots and foliage
• Use in a weed control program that includes multiple modes of action and overlapping residuals
Technology regulatory status
Trait:
• Full deregulation for stack in US and Canada for planting
• Approvals achieved in several importing countries
− China approval for RR2Y+Xtend™ stack in early February
• Still awaiting import approvals for stack in EU
− Expected by end of 1st quarter
Dicamba herbicides:
• There is NO dicamba labelled for in-­‐crop use
− 28-­‐day and 1-­‐in rain requirement before planting still in effect
• EPA comment period yet to open
• Labels for 2016?

What is BOLT™ technology?
• New herbicide tolerant trait available exclusively from DuPont Pioneer.
• Contains two non-­‐transgenic mechanisms of tolerance to ALS herbicides.
• All Pioneer® brand soybeans with BOLT technology are stacked with the Glyphosate Tolerant trait.
• Enables growers to use certain DuPont sulfonylurea products with their soybeans in new ways for more weed control options than STS® or other soybeans.
BOLT™ technology benefits
• More ways to control problem weeds
• Zero-­‐day plant-­‐back after key DuPont burndown herbicides such as DuPont™ LeadOff® and other herbicides
• Planting flexibility following DuPont™ Finesse® Cereal and Fallow herbicide use in wheat
• Flexibility to change crops after certain DuPont burndown herbicide use in response to changing market conditions
• Available exclusively in DuPont Pioneer genetics
Zero-­‐day plant-­‐back after DuPont™ LeadOff® herbicide
• BOLT™ technology is the only herbicide-­‐tolerant trait that enables farmers to use LeadOff® with zero-­‐
day plant-­‐back to soybeans following application
• LeadOff®:
– Blend of rimsulfuron + thifensulfuron (1:1 ratio)
– Rate/timing: 1.5 to 2.7 oz/a preplant up to 0 days before planting in BOLT™ technology soybean.
– Also preplant and preemergence in corn, preplant in cotton
BOLT™ technology enables: Plant-­‐back flexibility with DuPont™ LeadOff® herbicide for Pioneer® brand soybeans with BOLT™ technology
