So. IL | Before cover crops were planted we would plant into what ever was growing and spray the burndown with the pre-emergence immediately after planting. Typically gramoxone, atrazine, crop oil and something for grass. The quick activity of gramoxone made it easier to respray if a skip happened.
With cover crops such as annual ryegrass we are applying a burndown ahead of planting. The goal is at least two weeks ahead of the planter. We then apply the pre-emergence herbicides immediately after planting. Weather dictates when we plant. Have seen a month and more after the burndown that we finally got to plant. Damn glad in those instances that we applied a burndown ahead of time.
No matter which method you choose there will always be a year or two where just the opposite of what you decide to do would have been better. Gotta love farming when that happens.
