I am new to spraying and working on laying out my own chem plans. I have been trying to wade through as much material as I can to understand all of my options. Located in central IL, focusing on Waterhemp at the forefront of weed control. Corn/Soybean rotation, Conventional tillage ahead of corn, medium texture soils, planting starting mid April, 40" annual rainfall (although this year was very dry around 26"), GMO corn, and enlist soybeans. I really want to focus on crop safety and great weed control (don't we all!) because this will my first year spraying so I cannot afford any mishaps. It seems the coop has sprayed a lot of Callisto and there are some articles from the University of Illinois talking of resistant waterhemp with HPPDs so I want to try and avoid spraying HPPD pre and post ( I think I am best saving it in post?). Looking at a 2 pass program. Here is what I am looking at;

Option #1
Pre - Fulltime NXT (or Degree Xtra) 3qt
*2 lbs Acetochlor encapsulated (Surpass NXT)
*1 lb Atrazine

Post - Kyro 45 oz
*1 lb Acetochlor encapsulated (Surpass NXT)
*0.016 lbs Topramzone (Impact/Armezon)
*0.087 lbs Clopyralid (Stinger)
-0.5-1 lb Atrazine

Option #2
Pre - SureStart 2 (or TripleFlex 2) 2pt
*0.94 lbs Acetochlor (Surpass NXT/ Harness)
*0.095 lbs Clopyralid (Stinger)
*0.03 lbs Flumetsulam (python)
-1 lb Atrazine

Post - Impact Core 30 oz
*1.66 lb Acetochlor (Surpass NXT)
*0.017 lbs Topramzone (Impact/Armezon)
-0.5-1 lb Atrazine

Option #3
Pre - SureStart 2 (or TripleFlex 2) 2pt
*0.94 lbs Acetochlor (Surpass NXT/ Harness)
*0.095 lbs Clopyralid (Stinger)
*0.03 lbs Flumetsulam (python)
-1 lb Atrazine

Post -Armezon Pro 20 oz
*0.82 lbs Dimethenamid-P (Outlook)
*0.016 lbs Topramzone (Impact/Armezon)
-0.5-1 lb Atrazine


Worth noting, one field going to corn had 3 oz Valor fall applied in November, and I think I read you aren't supposed to mix Valor with group 15s from a crop safety perspective, so will this be an issue? If not I was wondering if anyone has run 1-2oz Valor in a corn pre program as generic can be had for about $1/oz.

I would be interested in any feedback (switching in generics where they fit or switching products entirely. I am wanting to save the Zidua for soybeans so that is why I was focusing on Acetochlor based programs. From what I have read Impact/Armezon is very crop safe, that was my reasoning to focusing on that versus Callisto (also because it has been used heavily in years past) but if this is not an issue then it sounds like Callisto would be cheaper. I also made these programs to stay under the 3lb AI/year with Acetochlor, but could I run something closer to 2.5-3 lbs Acetochlor upfront/pre and switch to Outlook or Dual post? I would be happy to use generics as long as they aren't missing safeners etc. Another question about encapsulated Acetochlor, is this worth possible extra cost for residual length and crop safety or not, and go away from Kyro and Fulltime NXT?

I have no idea on pricing, so if anyone has relative pricing to reference that would be great. Thanks in advance, I know there are a lot of questions here.
