The appearance of glyphosate resistant weeds along with the availability of the multiple stacked herbicide resistant seed will be a motivating factor for using herbicide combinations. Historically, herbicides used in combination have shown the mode of action of one herbicide which may antagonize the other's effectiveness. The underlying hypothesis is that soybean producers will continue using glyphosate and when/if glyphosate resistant weeds appear they will apply herbicide combinations commensurate with any herbicide resistant seed trait.
