Pre-Emergent for Dummies....

[OklaBrangusBreeder]

I have never in the past sprayed pre-emergent on my pastures... I think I want to give that a try this year.

So, some basic questions I'd like some help with.

* What products have you used that you would recomend?
* I'm specifically interested in ragweed elimination. Will this do the trick?
* What time of year do you apply?
* How do you apply it (I assume this will be a liquid applicaton?)
* What strength (gallons per acre?) do you usually apply?
* Do you leave the cows on the field or remove them?
* Is it usually a single treatment, or do you do multiple treatments?
* What does the cost per acre typically run?

And, feel free to add anything else you think I might need to know...

Thanks to all in advance.

What are you growing? Grass with broad leafs, or just grass?

Sorry, I should have been more clear...

My pasture is Bermuda grass. My main problem is getting rid of the ragweed...., but other assorted broadleaf type weeds also are present.

The problem with pre emrggrnts is the differtn germination times for different weeds.. The redidual affect will have worn off when some other types of weeds come up. Better to spray as they first start with something like Grazon, that will get the ones that have sprouted and leave a bit of residual for the next batch

I agree with dun, except I will add that the Grazon HL will probably do what you are wanting. it will kill broadleaf weeds, such as thistles, cocklebur, dandelion, broomweed, common mullein, curly dock, ironweed and ragweeds, and some brush.

I like using Diuron 80DF for pre-emergent on established pasture, hay meadows and newly sprigged meadows in NE Texas area. Right now is the best time to apply...then use Grazon Next for post-emergent applications.

If you have not already done a soil test I would recommend one. With proper fertilization the weeds will normally be choked out by the grass. I have heard that ragweed is a sign of low phosphorus.
That being said, I would agree with the Grazon.
