I recently met with a grower who wanted to put down a preemergent herbicide to get ahead of winter weeds. The crop he is growing has very limited choices but Surflan A.S. could be used. Surflan and other members of the dinitroaniline class of herbicides act by disrupting cell division in the roots of germinating seeds and resulting in death of the very young seedling before it even reaches the soil surface.
However, to be effective the herbicide needs to be where the root radicle of the seeds are so it either has to be incorporated mechanically or moved into the soil through rainfall or irrigation. The commonly accepted term for this is “activation”.
From the Surflan A.S. label:

Earlier this year, Lynn posted an explanation of herbicide modes of action and what that means for herbicide resistance management in orchards and vineyards.
I thought to myself "Self, we should put this in a table so it would be easy to understand". Then I remembered that we actually did this already in one of the four glyphosate resistance publications that I mentioned in an August posting.
Here's an excerpted table from ANR Publication 8501 "Preventing and Managing Glyphosate-Resistant Weeds in...
