Corn Programs

All our Fall Burndown programs, for acres to be planted to corn in the spring, include the following baseline chemicals: 24oz/acre of 5# glyphosate + 16oz/acre of 2,4-D LV6. (Referred to below at “Baseline”).

PROGRAM #1
Baseline + 2oz/acre of Generic Valor WDG (Flumioxazin 51WDG- Dry Product) OR
Baseline + 2oz/acre of Generic Valor SC (Flumioxazin SC- Liquid Product)
Non-ionic Surfactant at 0.25 v/v OR Crop Oil Concentrate at 0.25-1% v/v OR Methylated Seed Oil (MSO) at 1% v/v

PROGRAM #2
Baseline + 32oz/acre of Simazine 4L (Simazine- Liquid Product) OR
Baseline + 16oz/acre of Simazine 9-0 (Simazine- Dry Product)
Non-Ionic Surfactant at the rate of 0.25% v/v.

PROGRAM #3
Baseline + .3oz/acre of Autumn Super
Crop Oil Concentrate (COC), Methylated Seed Oil (MSO) or equivalent oil blend at 1% v/v
1.5-3.0 lbs/acre Spray Grade AMS

PROGRAM #4
Baseline + 1.5oz/acre of Leopard (Generic Basis Blend)
Crop Oil Concentrate (COC) at 1% v/v OR Modified Seed Oil (MSO) at 0.5% v/v OR Non-ionic Surfactant at 0.25% v/v

Other options include: Baseline + 4oz/acre of Metribuzin, Baseline + .6oz/acre of Panoflex, and Baseline + 1oz/acre of Elevore

Our approach to building an in-furrow program for corn might look a little different than your standard 10-34-0, 6-24-6 or 3-18-18 fertility program. We have pulled our traditional NPK starter blends out of our mix. Our in-furrow program consists of biologicals, humic/calcium blends, fulvic acids and amino acids. For growers running a 2x2x2 program we will utilize UAN 28/32%, ATS and boron. See a breakdown of our in-furrow program below:

In-Furrow Standard Program
16oz/acre of Environoc 401 Biological Consortium
64oz/acre of Humical
16oz/acre of Amino
10oz/acre of BLG

How It Works

• Environoc 401 contains 28 unique bacteria strains that release phosphorus, potassium & zinc. Enhances soil cycling processes for optimal symbiosis between soil & crops. Improves water retention and soil drainage, nitrogen fixation & mineralization. Enhances seed germination and vigor.
• HumiCal™ is an essential product created to keep your soil healthy and rich with nutrients. Specially formulated to help improve nutrient uptake which leads to increased yields and better crop quality. Calcium is an essential nutrient for proper soil structure which aids in porosity & oxygen to the soil, benefiting root growth & soil microbes.
• AmiNO™ helps the plant create vital sugars for better retention of yields in the face of stress.Increases uptake of other nutrients because amino acids create enzymatic reactions, your crop will uptake more nitrogen, phosphorus, potassium and other minerals from the soil.Decrease nitrate demand on your crops and improve growth & yield.
• BLG™ helps maintain the relative leaf water content and enhances nutrient transport. Greatly increases the carbon dioxide assimilation rate necessary for photosynthesis. Increases antioxidant enzymes which improve the plant's ability to defend against oxidative stress caused by abiotic stress.

PROGRAM #1
One-Pass Pre-emerge
20oz/acre Intrava DX (Amicarbazone + Metribuzin)
32oz/acre Moccasin II Plus (S-Metolachlor)
6oz/acre Argos (Mesotrione)

WHAT WE LIKE ABOUT THIS PROGRAM – Intrava DX (UPL) contains amicarbazone, a brand new active to the corn market that has no know resistance issues, making it effective in providing control over atrazine-resistant Amaranth species and HPPD-resistant pigweed. We had success in utilizing this program last year in Southern Illinois and anticipate this program being our lead seller in 2027. Intrava DX is a pre-emerge product only, without the need for atrazine.

TWO-PASS CONSIDERATIONS – If you intend to utilize Intrava DX as part of a planned two-pass corn program, I would run the following rates Pre-emerge: 16oz/acre of Intrava DX, 26oz/acre (~ 1.67pts) of Moccasin II PLUS and 4oz/acre followed by (Post-Emerge) 16oz/acre Atrazine 4L + 21oz/acre (~ 1.33pts) of Moccassin II PLUS + 3oz/acre of Argos (Mesotrione) + 32oz/acre of 5# Glyphosate. We include a Non-ionic Surfactant at 0.25% v/v. We also recommend a water conditioner.

PROGRAM #2
One-Pass Pre-Emerge
64oz/acre Atrazine 4L
4oz/acre Anthem Maxx (Pyroxasulfone + Fluthicet)
4oz/acre Argos (Mesotrione)

WHAT WE LIKE ABOUT THIS PROGRAM – We’re a big fan of the Pyroxasulfone active found in both Zidua and Anthem Maxx. This program is essentially building a better generic Lexar utilizing this active. Both Anthem Maxx and Argos (Mesotrione) are low volume products that free up space on the spray trailer. We also like the fact Pyroxasulfone is off-patent, and we anticipate a significant price drop in 2027 as many generic chemical manufacturers will have a Pyroxasulfone offering.

TWO-PASS CONSIDERATIONS – We utilize this program as part of a planned two-pass program. Our post-program is 16oz/acre of Atrazine 4L + 21oz/acre (~1.33 pts) of Moccasin II PLUS + 3oz/acre of Argos (Mesotrione) + 32oz/acre 5# Glyphosate. We include a Non-ionic Surfactant at 0.25% v/v. We also recommend a water conditioner.

PROGRAM #3
One-Pass Pre-Emerge
82.56oz/acre Brawl II ATZ
4oz/acre Argos (Mesotrione)

WHAT WE LIKE ABOUT THIS PROGRAM – Brawl II ATZ is a two-way blend of Atrazine & S-Metolachlor. Add Mesotrione and you have a generic Lexar product. There are two reasons I like Brawl II ATZ. First, Brawl II ATZ is formulated so that 2.58qts gives you 64oz/acre of Atrazine 4L (2lbs) & 26oz/acre (1.67pts/acre) of S-Metolachlor. Essentially maxing out your single pass Atrazine and S-Metolachlor load. Second, since Brawl II ATZ isn’t formulated with Mesotrione, therefore, you can dial up or down the Mesotrione oz/acre. This provides flexibility when utilizing as a one-pass or two-pass program.

TWO-PASS CONSIDERATIONS – In a planned two-pass program, the Brawl II ATZ label recommends 1.6-1.7qts/acre pre-emerge followed by .8-.9qts/acre post-emerge. In this scenario, we add 4oz/acre of Mesotrione pre-emerge and 3oz/acre of Mesotrione post-emerge (Maximum Mesotrione rate per/acre/year is 0.24lbs or 7.7oz/acre/year). We also include 32oz/acre of a 5# Glyphosate with our post-emerge pass. If you elect to run the maximum rate of Brawl II ATZ (2.58qts/acre) as a one-pass program and have weed control issues requiring a second-pass you still have head space to run another 0.5lbs/acre or 16oz/acre of Atrazine 4L, along with 3oz/acre of Mesotrione, and 1.33-1.67pts/acre of S-Metolachlor + 32oz/acre of 5# Glyphosate. Non-ionic Surfactant at 0.25% v/v. We also recommend a water conditioner.

PROGRAM #4
One-Pass Pre-Emerge
96oz/acre of Stalwart 3W (Atrazine + Metolachlor + Mesotrione)
Optional: Add 24oz/acre of Atrazine 4L to give you 2lbs atrazine/acre

WHAT WE LIKE ABOUT THIS PROGRAM – 3qts/acre of Stalwart 3W (Generic Lexar) has been the economic go-to program for years. Cheap & Easy. Based upon the formulation of Stalwart 3W, a 3qts/acre pre-emerge rate gives you the following active equivalents/acre: 40oz/acre of Atrazine 4L + 21oz/acre (1.33pts) of Metolachlor + 5oz/acre of Mesotrione. To increase its effectiveness, we encourage our growers to add 24oz/acre of additional atrazine to bring the total to 2lbs/acre. We are also looking at potentially adding generic pyroxasulfone to deliver another Group 15 active for increased residual control similar to a product like Storen® that contains two Group 15 chemistries.

TWO-PASS CONSIDERATIONS – Stalwart 3W is my least favorite product to run in a two-pass program. I just don’t like the overall formulation ratio of atrazine, metolachlor and mesotrione. I believe this product is meant as a true one-pass program at the 96oz/acre rate. With that said, if I were to use this product in a two-pass program, I would run the 96oz/acre rate as a pre-emerge followed by 16-40oz/acre of atrazine, 1.33-1.67pts of S-Metolachlor and either Shieldex, Centavo or Tough 5EC + 32oz/acre of 5# Glyphosate. I would not run mesotrione on the post-pass because I would only have 2.7oz/acre of headspace before maxing our my mesotrione load (7.7oz/acre/year). With the 96oz/acre pre-emerge rate we already applied 5oz/acre of mesotrione. Alternatively, you could run 1.5-2.0qts/acre as a pre-emerge followed by 1.25-1.75qts/acre post as suggested within the label. Adding 32oz/acre of 5# Glyphosate. We include a Non-ionic Surfactant at 0.25% v/v. We also recommend a water conditioner.

We listed several one-pass corn programs under our Pre-Emergence Program section that could also be used as a two-pass program (pre + post). In this section, we are focusing on our go-to post-emergence programs independent of what we utilize as a pre-emergence program. In our area, the old standard post-emergence program (PROGRAM #1) utilizing 3oz/acre of Mesotrione is not near as effective as it once was; We are struggling to consistently get a kill on waterhemp. As a result, we are utilizing other HPPD chemistries as a replacement and/or supplement to Mesotrione.

PROGRAM #1
16 oz/acre of Atrazine 4L
21oz/acre (~1.33pts) of S-Metolachlor
3 oz/acre of Mesotrione
32 oz/acre of 5# Glyphosate
2 oz/acre of Fulltec Adjuvant
16 oz/acre of Relax Rx OR 14 oz/acre of Fulltec Nitro (Foliar Stress Reliever)

WHAT WE LIKE ABOUT THIS PROGRAM – This has been a standard go-to program for our corn post-pass over the years. Cheap and generally cleans up anything that gets through our pre-emergence residual. We will continue to utilize this type of program where we have very little weed pressure or waterhemp is 3” or less at time of application. We believe the labeled rate of 3oz/acre post for Mesotrione is not effective when weed pressure is high or when waterhemp is dense and greater than 3-4”.

PROGRAM #2
16oz/acre of Atrazine 4L
21oz/acre (~1.33pts) of S-Metolachlor
1.0-1.35oz/acre of Shieldex (Tolpyralate)
32oz/acre of 5# Glyphosate
2 oz/acre of Fulltec Adjuvant
0.5-1.0 v/v Methylated Seed Oil (MSO)
16 oz/acre of Relax Rx OR 14 oz/acre of Fulltec Nitro (Foliar Stress Reliever)

WHAT WE LIKE ABOUT THIS PROGRAM – Shieldex is a different class of HPPD (Group27) chemistries. It is like Impact (Topramezone) HPPD (Group 27) in the fact it has some control of grasses. Regardless, we still add 5# glyphosate to the tank-mix. Shieldex 400SC is a replacement for mesotrione. We have had good luck utilizing the 1oz/acre rate of Shieldex in fields where waterhemp pressure is high and less than 5”. I’d recommend running the higher rate of 1.35oz/acre if you are battling larger weeds. Label recommends Shieldex 400SC Herbicide prior to weeds exceeding 5 inches in diameter and/or height. Shieldex 400SC Herbicide can be applied up to the 6 leaf collar (V6) stage or up to 20 inches tall, whichever is more restrictive. Keep in mind, when utilizing Shieldex 400SC with atrazine, you are restricted to up to 12” tall corn.

PROGRAM #3
16oz/acre of Atrazine 4L
21oz/acre (~1.33pts) of S-Metolachlor
3oz/acre of Mesotrione
8oz/acre of Tough 5EC (Pyridate)
32oz/acre of 5# Glyphosate
2 oz/acre of Fulltec Adjuvant
16 oz/acre of Relax Rx OR 14 oz/acre of Fulltec Nitro (Foliar Stress Reliever)

WHAT WE LIKE ABOUT THIS PROGRAM – Tough 5EC has been a go-to product when our pre-emergence chemistries don’t quite provide the control we were hoping for. Tough 5EC (Pyridate) (Group 6) is a bolt on product that we use in conjunction with mesotrione. Labeled rates are 8-24oz/acre. We generally run 8oz/acre with our post-program, however, in fields with dense waterhemp pressure and where we are dealing with waterhemp greater than 4-6”, we have run up to 12oz/acre with success. Corn may be treated up to the 8-leaf stage of corn growth. Keep in mind, when utilizing Tough 5EC with atrazine, you are restricted to up to 12” tall corn.

PROGRAM #4
16oz/acre of Atrazine 4L
21oz/acre (~1.33pts) of S-Metolachlor
9oz/acre Centavo™ (Clopyralid + Mesotrione)
32oz/acre of 5# Glyphosate
1% v/v Crop Oil Concentrate (COC) (PREFERRED) OR 2 oz/acre of Fulltec Adjuvant DO NOT USE MSO
16 oz/acre of Relax Rx OR 14 oz/acre of Fulltec Nitro (Foliar Stress Reliever)

WHAT WE LIKE ABOUT THIS PROGRAM – We like the fact this premix is easy and we are automatically partnering our mesotrione with another mode of action. Label recommends utilizing Centavo on actively growing weeds less than 3” tall. To minimize weed competition effects on the crop, apply this mixture to 1 to 2-inch tall weeds and before the corn reaches 24 inches in height.

Since we are in Southern Illinois, our actual fungicide recommendation might be slightly different than what we might recommend if we were a little further north in the state. The main reason, we experience Southern Rust every year and our focus is on blends that provide control of that disease. To date, we have very little Tar Spot in our geography.

PROGRAM #1 – Our Go-To Program
14.0 oz/acre of AzoxyProp Fungicide (Azoxystrobin + Propiconazole)
7.0 oz/acre of Sivora (Flutrifol)
2.7oz/acre of Fulltec Cube
32 oz/acre of Phycoterra FX
3 oz/acre of Lambda Cy
2 oz/acre of Fulltec Adjuvant

WHAT WE LIKE ABOUT THIS PROGRAM – We’ve been successfully utilizing this program for 2 years now. Essentially, we are building our own TrivaPro using generic Quilt Excel and Sivora (Generic Top-Guard) at about 2/3 the cost. Flutiafol, the active in TopGuard, is the most mobile and longest lasting residual fungicide in the marketplace. We also include Phycoterra FX, a micro-algae bio-stimulant, and Fulltec Cube, a Becks PFR Proven product. When we are dealing with budget constraints, we will substitute Fulltec Cube for 16-24oz/acre of Born 7%. We also include lambda cy insecticide and Fulltec Adjuvant, another Beck’s PFR Proven product. For additional information on these products check out their individual product pages on our site.

PROGRAM #2 – Branded TrivaPro Program
13.7 oz/acre of TrivaPro Fungicide (Azoxystrobin + Propiconazole + Benzovindiflupyr)
2.7 oz/acre of Fulltec Cube
32 oz/acre of Phycoterra FX
3 oz/acre of Lambda Cy
2 oz/acre of Fulltec Adjuvant

NOTE - The only difference between these programs is the actual fungicide itself. For those who prefer a branded fungicide we utilize TrivaPro as our go-to branded fungicide.
