Many growers are finding a heavy second flush of weeds coming after their first Glyphosate application.In some fields like that shown above this second flush is very dense and lush.In fields that have already canopied a grower will have no choice but to drop pipe another application of glyphosate.

An overall application of gyphosate at the 8th true leaf stage will not hurt the corn crop but the canopy makes its extremely difficult for the spray to reach its intended target.Glyphosate is a contact herbicide.Several growers have indicated to me that they will not be caught again using Glyphosate as a stand alone product.Instead they will be applying either a residual grass or broadleaf herbicide to go along with their glyphosate when its applied at the 3-4 true leaf stage.
