These shots were taken on exactly the same day.The grower above was going to apply his Glyphosate the following day. I asked him why he was in such a hurry.He commented that the corn was going to be getting past the Critical 3 leaf stage and he felt that he shouldn't wait any longer.I remarked that it was true that you should apply your Glyphosate by the 3 true leaf stage but that was based on the prescence of significant weed pressures ( like that showing in the bottom shot). If you don't have significant weed pressures there is no need to rush your application.Apply your Glyphosate based on when weeds start showing up. KEY LEARNING :Though the key to maximizing yield potential is keeping your crop weed free from the 3-8 true leaf stage base your post emerge spray application on weed pressure prescence and not stage of crop growth.
