absolutely..
i think preen is merely trifluran,
there are lots of other pre-M's that will work very well

I checked the CDPR website and it's still registered.

actually greenfrog...
as much as sheshovel's sig line is quite accurate.... this time i think she is right...(oh my gosh... i actually said that :) )

when i googled preen to try and verify that it was trifluran, on the preen website it says "NOT FOR USE IN CALIFORNIA"

I didn't see it on the label and the registration for CA is still current.

This is the link I used for the label and my previous post has the link for CA registration.

I will admit that I still could be wrong especially since I have never used Preen. I did see it last spring at Costco though.

Granular pre-emergent chemicals work very, very well. Use it in rock, under bark, and on any beds where the customer is too cheap to want bark. There are other products besides Preen. Make sure whatever you want to use is not banned in your state, first. Always keep everything legal and you'll sleep nights.

Of course you can use it over stones, but be aware of the increased run off and dig down and see if there's any WB or plastic. These will affect absorbtion. Granular is good. Liquid is better. Especially on hills.

It's the same thing (AI)...just a different concentrate. Both contain Trifluralin and Isoxaben (atleast that's how I THINK it's spelled) lol:)
