| A new supplemental label allows the use of Valor before field corn emergence in no-till or minimum tillage. Apply in the spring 14 to 30 days before planting at a rate of 2 oz/A. Valor will provide residual and some burndown activity, if used in a burndown treatment it is recommended to be applied with an appropriate burndown partner such as 2,4-D, Gramoxone Inteon, or a glyphosate product. Do not apply irrigation until field corn is at least at the 2-leaf stage. Do not incorporate crop residue. Valor has good to excellent preemergence activity of black nightshade, lambsquarter, pigweeds, horseweed/marestail, and waterhemp. | |||||||
