I have been reading the literature on these two and it seems that you can't put them down together?
You can add Speed Zone to a pre-emergent if it is the proper type.
How about Pre-M 3.3 EC Turf Herbicide to Speedzone?
Pre-M 3.3 EC notta big fan.
PENDULM 3.3 in an AMINE based chemical. SPEDZONE is a ESTER based chemical. buy rule (at least what i've been told) don't mix very well, and will seporate and not stay in suspension, jell-up, etc. just do a jar test and that will answer the compatiblity question. just ues SURGE, it has the same chemical make up as SPEEDZONE, but it is an AMINE based.
I kinda wonder where they use Pre-M 3.3 EC .....since the stuff will stain it surely can't be used around sidewalks and buildings? I guess it must be a cheap pre-m that is mainly used in backpack in beds?
i used to use it on everything, now just on beds and some select commercial/hoa sites that the smell and staining are not that major of a concern. dimension on everything else.
Ester based 2-4-ds don't mix well with all sorts of things, especially Prodiamine (Barricade) and not super well with Pendi. products. If you're going to use Pendi. use the Aqua cap, it only costs a few cents more and doesn't stink or stain nearly as badly.
Can you post a link to the the literature that says you cannot put speedzone and pendimethalin 3.3 ec down together.
All esters need more agitation that amines. With normal agaition, I don't see where their is a problem.
Don't have a link, just experience. You certainly can put down pendi. with esters, but it is harder to keep suspended. Esters with Prodiamine I wouldn't recommend at all. Never met anyone who didn't have serious suspension problems, to the point of clogging filters and such.
