I picked up a used Ritchie Bestway 100G sprayer to try to get milkweed & thistle under control. Bought 24D and cimmarron and surfactant.
Looking for advice. My supplier tells me .375 oz Cimmarron/acre and 1-qt of 24d.
He said I should be spraying about 20 gallons/acre.

Sound right? Any suggestions?

Cimarron can be very hard on Timothy, so follow the directions closely. I have had better results spot spraying milkweed moreso than broadcast spraying. Of course, if you have alot of milkweed then you will need to broadcast spray. 20 gallons to the acre would be a good amount. It is better to put plenty of water downthan not enough and at this time of year weeds begin to get pretty tough. Surfactant is a big help for tough weeds and at least a quart per 100 gallons should do fine. Sounds like the mixing advice is good.

Should i just do 2-4-D and skip Cimmarron?

Cimmarron will kill some weeds that 2-4d won't....just read and see what it says is the safe dosage is for Timothy.

I farm in Pa. also I would not worry about the Timothy, If the field is very weedy I doubt if any Timothy exisits

It's a nice plot of thick dark green grass, but invaded with milkweed on about 1/3 of it

see if u can find interlock to go with other chemicals helps absorb dont skimp on the suf

[JD3430]

sprayer has .40 nozzles. Is that OK for chemicals I'm spraying/

[dubltrubl]

Is that the capacity #? If so, you can, but you'll have to be hoofin it in the field at about 6 mph to get an application rate of 20 gal/ac. At 4 mph you'll be applying 30 gal/ac. Either adjust your mix accordingly, or get a smaller nozzel if your shooting for less gal/ac. By the way, Tee-jet has a cool nozzel chart that lets you look up nozzel sizes and capacities. Might help.

I was shooting for a 5mph application rate of speed. Looked like it said 18 or 19 gallon per acre with 40 nozzles.

HERE.Milkweeds are not a problem in hay if it is cut 2-3 times per yr.The cutting gets rid of them.They don't come back the next yr.

Sooo,Why are they a problem farther east?Maybe a different milkweed variety?

[slowzuki]

Here further east we only get 2 cuttings max, but the milkweed need about 4-5 cuttings a season to kill them. So to get rid of milkweed you need to take the field out of production for second cutting and find time to keep mowing it every 3 weeks or so. No one owns batwings here either so its dragging your hay mower over it.

Probably could make it work if you lowered your pump pressure. Just keep in mind that a lower pressure will affect droplet size. May or may not be a concern, just gotta use some common sense. Good luck!

Supposedly milkweed kills horses. Don't want anything to do with that. Learning that cows like it, though.
This crap is in my good timothy stands.

Keep me posted on your results JD3430, I have it coming out in my O grass fields at spots and i already sprayed once after 1st cut w/ 24D, now it needs a shot again after taking my 2nd cut off. My local ag store told me 24D is just a temporary fix it will not kill is to the roots, that i need to go w/ Cimmaron and Surfacant you mention to try and knock it out to the roots, but they also now is not the time needs to be growing for this stuff to work, and we have been pretty dry here in PA and lots more heat on the way this week. 3rd cut on my O grass doesn't look promosing less we get some more rain. Good luck keep me posted

[slowzuki]

I don't think anything will kill milkweed in one pass application, it has a massive root stock system if it establishes more than one year. I know to kill it without chemical requires frequent mowings, basically turning your hayfield into a lawn after first cut.

[JD3430]

Yellow and wilted. Going into the tan/brown stage, but still standing. I ended up mowing a patch of it on another lot.
