Sunflowers-How long after herbicide application?

Thanks to the previous comments and posts on planting sunflower seeds. I plan to plant 2 acres worth. In preparation for planting I have mowed down the field and applied, Hi Yeild Killsall to burn down the grasses. Was looking on their instructions and cannot find a clear amount of time a guy should wait to plow/disc/ then plant the seed. It has been 5 days since herbicide application and the grass has stopped growing and starting to turn lime green in its preparation to turning brown. When do you all reccommend plowing/discing and planting the seed. Since sunflowers are technically a "weed" I dont want to put them in too soon, but the window of opportunity says to get them in before mothers day. Also it hasnt rained here for over a week or so and I like to plow when the soil is soft.

I would contact your local Extension Office.

This stuff, or a different formulation? Some things have just a letter or two behind them, making them a completely dofferent formulation, so we need to be exact, and your name of the product wasn't any too clear? I'm not trying to be critical, but the details on this are -important- is all.

If this is just a generic 4lb glyphosate product, then technically once it is sprayed on the ground it attaches to clay bits or kills green plants, but has no activity on any seed in the ground.

So, you could plant an hour after you sprayed it won't affect whatever you are planting. Has no effect at all on the seeds in the ground.

Legally, you need to follow the label.

To make sense, you need to let the weeds die before you work the ground up. Typically folks like to wait 3-5 days for the weeds to translocate the chemical to their roots so the glyphosate takes affect and actually works for you.

So, you could plant right away and not harm your seeds; you probably want to wait 3-5 days so the spray does you some good.

Again, this would be for a generic glyphosate with nothing else in the mix. I'm not 100% sure what you actually used?

If its the label paul showed its just generic roundup which I have used. Like he said, wait about 4-5 days and work the ground. The label should tell you that. Glyphosate is the fancy word for roundup as it states on that label.

That's the one thanks for the advice
