Charles is there any thing in your yard that bees may be getting nectar or pollen from?

I won't get my bees until the tenth of April. But yes. We have several species of flowers.

Actually I was referring to things like henbit, that may actually be sprayed in the yard itself. Some beekeepers have it as I remember a discussion on henbit and one of our keepers having it in his yard. I do not know the specifics of the rules of pre-emergent sprayed in the general area of a beehive.  would not want to spray it on anything my bees may gather from. Even yard henbit or clover etc. You might check with one of the farm leaning Universities in your state for guidance if you do not get a satisfactory answer here. Those folks are usually quick to respond and glad to help.

Ok. I do have quite a bit of henbit. I'll do some more research. I'm leaning towards not using it. Thanks.

Does a chemical have an effect? Yes, they all do at some level.  On the other hand, a pre-emergent works by forming a thin crust on the surface of the soil, and any germinating seed is killed in that crust.  So a pre-emergent doesn't kill weeds, it only kills seeds. It works best obviously on undisturbed soil that is well packed down. 

Birds do eat it, results unknown.  It may kill some desirable plants such as ajuga - read the label for details.  Will it get into plant nectar? Probably not in any significant way.  Will it kill bees? It's not targeted to kill insects, as GMO seed is.  A pre-emergent is not a pesticide, it's a selective herbicide.

I really think Charles is speaking of a Post Emerge, (weed killer), as he stated henbit is present.

Regardless of its description of function, I for one would not want any chemical sprayed on anything my bees may be forging on. For my bees sake as well as my own.

Types of herbicides
After figuring out what weeds need managed, the next step is to understand the types of tools at your disposal. Here are some common categories of herbicides, each for different situations.

Pre-Emergent: Prevents germination to keep weeds from ever growing
Post-Emergent: Kills actively growing weeds through contact
Selective: Targets specific monocots (grasses) or dicots (broadleaf plants)
Nonselective: Kills any plant that it contacts
Total Vegetation: Kills all existing plants and can prevent future growth

I hope this helps.

The OP wrote plainly, "pre-emergent." That's "Preen" product, and the like.  The Original Poster's question is what I responded to. 

It is unknown what is involved in whatever advertisement you are quoting, or why you included it...? because the OP didn't ask about the ad you quoted....?

True but the point is pre emerge is sprayed On the problem area. So if henbit is the problem area then here we are?  I for one do not want my bees 🐝 on that. Only my opinion. Each to his own.

If a plant is visible, it has already "emerged." No PRE-emergent will stop it now. 

It requires an herbicide to kill a seedling already EMERGED.  Herbicide works in a different way.

"Pre" means, "before" emerging from the soil.  The seed may germinate, but it won't make it through the crust formed by the pre-emergent. 

Most home/DIY pre-emergent is granular, such as Preen. 

And yes, I see you are clearly voicing your opinion.  But the OP asked for analysis on the safety of using a PRE-emergent which is a soil-based application, not a foliar application.

Exactly... Adding; If pre emerge is was intended to be added to the yard, then it is too late because henbit is already up and probably other things too. That is why I said what I did about POST emerge. Adding to your description of pre emerge does not kill plants, only stops seeds for germinating. ie.  Which stops undesired plants form coming up in the first place. Isn't that what your post was about? I added to the conversation looking at both sides of the equation. Hopefully you haven't taken offense?   

Quoting you.
ie "So a pre-emergent doesn't kill weeds, it only kills seeds."
