I say you're fine. If you disced in, you're good, N not going anywhere. If atrazine had clean soil to stick to, you are fine.
Don't matter a lick then. The Urea/N is happy as a clam under the soil. Seeds are patiently waiting for a rain (very well could germinate without a rain to be honest). Atrazine is stuck like glue to that soil - you have a recipe for a good stand unless something else went wrong or goes wrong. sounds good to me though. time & lack of rain for a couple weeks isn't your problem. Sounds great
Hmmmm. I'd research post emergent herbicides for sorghum or milo see what come up with. What type of grasses? There's a "chance" u could spray it all with atrazine, crop oil & even add 2,4-d (broadleaf killer but would stress those annual grasses u don't like.). This combo has potential to kill. Depending on what's there. I know a little research may help as well for specific post emergents. Now- off the top of my head- I'd see if ur grass is killed on the Qinclorac label. If it is- if u had all the time in world & effort.... I'd do quinclorac, atrazine, crop oil, possibly 2,4-d and spread some treated urea on it. Likely your weeds have been eating up the N and it sure would help.
EW Likes "dry" so if we get drier, u very well could still see it blow past the weeds. Purely depends on what type and how bad though. What type of weeds & a pic always help if able. Good luck.
I will see if I have time to take one tonight. Grass is grass. A few other people are having problems with it in the area. I agree on the heat.
I looked up Quinclorac label on my phone to recall some old memories on weed species targeted.. Really quick glance.... I'm thinking that's the ticket. FOX TAIL for example - BAM. Grabgrass, etc, etc, etc . No - grass isn't grass but I'd bet you 75% sure it's killable with Quinclorac if I was a gambling man - based on what types of grasses like to grow through Atrazine, almost sure. For example, foxtail is a common one to go through atrazine. Quinclorac, atrazine, crop oil and I'd do 2,4-d & last... I'd either put on treated urea, slow release OR just go to any hardware store/lawn store & buy "weed & feed" which essentially has treated urea with 2,4-D in it. Remember, with EW - usually guys are planting "strips", 1/50th to 1/10th an acre for example is fairly common. Well, babying that is CHEAP. That's what I'd do if it were me. Heck, you could even bring some water tanks and possibly knock a big strip out with a back pack sprayer with a little finesse.
Quinclorac, I'm sure can be bought online. It's a granular soluble that comes in containers you mix in sprayer. Easy, cheap, effective and just mix with some atrazine & crop oil & possibly 2,4-d and replace N that's been robbed by weeds. Sounds complicated but it's not. Good luck though.
Thanks Skip. Depending if my ATV gets fixed or not I will try it. How much of each are you thinking?
I'd just go labeled rates on everything. Very light if you go with 2,4-d with the heat. Possibly skip it if heat is bad. Actual N to ground, I'm gonna guess if EW is light green in color (lacking N), it could use ACTUAL 40-75/lbs to acre. Atrazine, not that big of deal, unless you're planting something different there BUT most won't reach soil anyways so I'd also go heavy on that. Crop oil, varies on type, some is hotter than others- read label as crop oils vary for rates. Quinclorac, I'd go max rate on that, IMO. High water volume to drench everything. Good luck!
