Soybeans

Technologies

All the traits you want. None that you dont.
Glyphosate Tolerant (GT) Soybeans

Overview

  • Still a popular and viable choice in some areas
  • Most economical trait option
  • Waning product lifecycle due to weed resistance

Advantages

  • By far the lowest priced trait option – ~$15+ per unit less expensive than other technologies
  • Still very effective where resistant weeds are not an issue
  • When mixed with residual herbicides, weed resistance can be diminished

Disadvantages

  • Glyphosate-resistant weeds render the technology ineffective
  • No soil activity, must be mixed with a residual herbicide for lasting performance
  • Susceptible to off target movement from dicamba sprayed on nearby crops
LibertyLink®

Overview

  • Moderately priced trait option
  • Continues to increase in market share every year
  • Good choice for glyphosate resistant weeds

Advantages

  • Excellent control of glyphosate resistant weeds, especially Palmer amaranth and waterhemp
  • No known weed resistance in corn/soybean growing areas
  • Nice herbicide rotation compared to other technologies to help reduce resistance

Disadvantages                                                                                                                                                       

  • Herbicide is relatively expensive
  • No soil activity, must be mixed w/ residual for lasting control
  • Contact only, not systemic
  • Requires copious amount of water (20+ gallons per acre)
  • Good weather required for effective kill
LibertyLink® GT27TM

Overview

  • Stacked glufosinate (Liberty®) and glyphosate
  • Moderately priced trait option compared to other technologies

Advantages

  • Two modes of action to help reduce weed resistance
  • Offers more herbicide flexibility than straight GT or LibertyLink® soybeans

Disadvantages

  • Doesn’t bring anything more to the table than straight LibertyLink® when dealing with glyphosate resistant weeds
  • Still must add a grass killer to kill volunteer corn if corn was LibertyLink®
Roundup Ready 2 Xtend®

Overview

  • Newer trait option to help combat glyphosate resistant broadleaves
  • Stacked with glyphosate resistance
  • Has been rapidly adopted by growers

Advantages

  • Good to excellent control of glyphosate resistant broadleaves such as marestail, kochia, Palmer amaranth, and waterhemp
  • Not affected by off-target movement of dicamba sprayed on neighboring fields

Disadvantages

  • Expensive Seed – $20+ more per unit compared to GT soybeans
  • Expensive herbicide program – Only approved branded products can be used, no off-patent products
  • Must be mixed with glyphosate and/or other grass herbicides

Disadvantages (continued)

  • Herbicide contains same active ingredient as most popular corn herbicides, how long until no longer effective?
  • Off target movement is a big concern, future uncertain?
Enlist E3TM

Overview

  • 3 way stack of glyphosate, gluphosinate (Liberty®) and 2,4-D choline
  • Most effective weed control options
  • Seitec will have numerous varieties and good supply once Chinese approval is received

Advantages

  • Clearly a premium weed control product with tolerance to 3 distinct modes of action
  • 2,4-D choline appears to have less drift and volatility concerns than Dicamba
  • Offers a higher degree of weed resistance mitigation compared to other technologies

Disadvantages

  • Price: Both trait and herbicide (EnlistTM One/EnlistTM Duo) will command a premium
  • Residual herbicides will still be important to use
  • Like all other Non-Dicamba traits, Enlist E3TM will be susceptible to Dicamba injury
  • Not yet approved in China
