CIR is great in iowa.
Kanlow is also very good. Kanlow is slightly better on bottom ground but still good on better upland soils. I would avoid kanlow on junk soils.
Liberty is another Great one but hard to find. Easy to find & good: Shawnee, sunburst & usually folks have option for an iowa ecotype. Any of above - I’d do 2, ideally 3 & be in great shape.

Good general article on switch, herbicides, obstacles & solutions. Few things I disagree with based on my experiences but overall pretty good.

Oust ! SFM75
Burned in March because time . Spayed 2 oz acre oust March 1st . Clean as whistle May 1 this area was getting bad with junk . Cleaned up nice . Nothing but switch . This is a 20 foot wide border on a food plot to conceal . Didn’t get the best burn but oust did the trick !!

Agree on this. I’d spray soon out of “safety”. There is some varieties that can germinate earlier than others. You are spot on for varieties like CIR & kanlow. Time yet. But- If mine, I’d probably drop a bomb on it.
Go nuclear !! This is my spraying over the weekend....
Issue you will have is switch needs to stratify (freeze/thaw multiple times). Maybe you have done this an alternative way?
Yes, I’ve been freezing thawing it for awhile.

Super curious on this method. Have you done it before successfully?

I’ve done this several times , soaking in water for 24 hours , fridge for 30 days dry and plant . I did work the ground before I planted went heavy on atrazine 4 qts . Planted June 1 and had a great stand . I mixed in some pearl millet small amount was told if millet takes CIR would don’t know about that but both came up and great clean stand .

I am being advised that I should drill but I already Frost seeded. I haven't mowed the broadleafs yet. It is the first week in May. The areas I Frost seeded were last years beans and last years corn. I did spray Simazine and round up in March.

Id spray again and let it eat . How much simazine per acre did you put on ? Id possibly put a few more quarts per acre on at this point to keep it clean .Worst case it doesn’t come up till next year . Not sure what your seed rate was ?
