a pre-plant application of glyphosate + 2,4-D Ester 700 (left) is adequately controlling giant ragweed in soybean that is resistant to glyphosate (right)
From left to right and at the back. Post emergent applications of Lontrel, Banvel II, MCPA and 2,4-D ester. Contrast that to the front where the same four herbicides were applied pre-emergent, but due to no precipitation since application, no injury or weed control has been observed.
red clover control in the spring following a fall application of glyphosate + 2,4-D
control of red clover in the spring following a fall application of 2,4-D
Typical leaf distortion as the result of 2,4-D applied prior to soybean emergence but ignoring the pre-plant interval specified.
