Rice is tillering in the flood; we’re quickly approaching mid-season and some is already there. We have missed this rain so far, so if you can get the 2-4 leaf rice sprayed, get some nitrogen on it in front of rain tomorrow night.  If we miss rain, we will take it into shallow flood. Keep it moving, we’re burning daylight!

If you are out walking your corn fields and notice silver or dull grey marks on the leaves it’s most likely to be silver leaf. This happens when there is a rapid temperature drop with low humidity, and temperatures dropping into the low 40’s. Making sure your plant is healthy and strong is the only treatment here so it can grow out of it.

Consider not replanting beans in June when the emerged bean stands are above 80,000 and are past V2.  Adding more beans to the field past V2 will not improve yield and may drop it from mechanical loss from the replant.

Evan Zimmerman


With planting still delayed in most of the region, many acres of corn are being converted to soybeans.  Consider planting Enlist E3 soybeans.  Enlist E3 soybeans have three tolerances:  2,4-D choline, glyphosate, and glufosinate, giving farmers multiple, effective options for weed control this growing season.  Also, the Enlist E3 soybeans have a wider application window of no later than R2 (full flower) and no application cut-off date when compared to the R1 (beginning bloom) cutoff in the Xtend soybean crop system with a July 15th cutoff date for Illinois.

Tile makes you money.  The downtime and loss in bushels outweigh the costs of laying tile.  You can often tile into an existing crop and be ahead in expense with lower material costs in the off-season and increase bushels that same season.

Paul Helland


Crops have been growing very rapidly now that the heat has come. This has also caused the plants to take in the herbicides we spray a lot quicker. You may want to tone down the adjuvants that you use with sprays to avoid crop response. For example, use a non-ionic surfactant with Callisto and glyphosate versus crop oil.

Our corn is getting to canopy in places and is really coming around. It is not too soon to be on the lookout for diseases in your corn. We need to protect the corn at V6 and make sure we are giving it plenty of fertilizer at this stage. We are determining ear girth currently.

Dillon Gipson

Tissue sampling is a road map to what your plant is needing and has enough of.  I have had a lot of farmers asking me about getting nitrogen on early. My answer is always the same, “What do your tissue samples say?”

With the tough growing conditions on the corn last year, we had a lot of corn fall over. Because of that, there will be more volunteer corn in soybeans this year. Using a corn killer is a great option. Clethodim at 6 oz will do a great job and be affordable.

Sam Geistfeld

The area had hail over the weekend in spots.  I have noticed some soybeans and corn in pretty tough shape.  If you would like help evaluating your crop damage, call an agronomist to come out and scout fields with you.

We have some reports of white corn or white leaves on corn.  We have found it to be Callisto overload from overlapping over headlands.  Sometimes it is caused by spraying corn when it is stressed from cold and wet conditions. After a few days of sunshine, the corn will come out of it.

Doug Dohlman

Hop Vine Borer. Don’t know what it is? You’re not alone. This was found in southeastern MN and it came in from the ditch area and started feeding on the first couple rows of corn. They enter the plant from below and tunnel up. The plants will look stunted and even die. There are no BT traits for control so an insecticide that has cutworms on the label will control them, but only when they are moving from the grass to the corn. Once they are inside the corn you can’t get an insecticide to come in contact with them. I’m infested areas, mow the grass to try so they can’t overwinter as easily.

Prevent plant acres are getting burndown applications applied over the next few days. Most of the weeds that are out there at the moment will most likely not be removed by a digger. Enlist Duo or Parazone would be two good choices for burndown.  Warmer temperatures and higher water use for better coverage is going to be the key to getting good control.

I have been getting several calls about rainfast times on herbicides. As a general rule, if a product has been on for 4 hours you are likely pretty safe. Every label does have a specific time listed on it to watch, though.

When tissue sampling early stage corn (less than 12 inches tall), take the whole plant except the roots and soil. Mid-season, take the last collared leaf as a tissue sample. Pick one or two spots in the field and mark them with a flag or GPS so you can come back to them throughout the season.

Nikki Schmitz

The early seeded wheat is starting to push out the flag leaf.  With the cool, moist conditions we have been experiencing, fungicide at the flag leaf stage would be very beneficial for a high yielding wheat crop.

Terry Funk

Before you spray your Roundup Ready, Xtend, LibertyLink, or Enlist soybeans, make sure you have checked with your neighbors to make sure what soybean traits they planted this spring. A quick text or phone call could help prevent problems with possible spray drift.

Jeff Bates

Are you having a tough time with Roundup Ready volunteer canola in your soybean fields?  Pursuit is one of the best herbicides to control volunteer canola post-emerge in your soybean crop. Products like Extreme or Thunder Master are pre-mix products of Roundup and imazethapyr (same A.I. in Pursuit) that go on at 2 pts/acre to give you excellent post-emerge control as well as residual control.  One thing to keep in mind is that imazethapyr has a long rotation restriction to crops like potatoes and sugar beets.  If you don’t have those crops in your rotation, this product might be a great tool to use on your farm.

Jordan Swanson


If you will not get your soybean acres sprayed this year with Xtendimax or Engenia, you need to look at other options.  Flexstar or Cobra along with a Roundup application would be the next best options at this time, depending on your weed spectrum. You may also want to add in another residual now to get beans to canopy.

Dean Christiansen

Volunteer corn is really starting to take off around the area.  If you are spraying dicamba this week on your beans, remember there will be antagonism between clethodim herbicide and dicamba, so you will have to increase the rate of the clethodim to get good volunteer corn control.

When putting broadleaf weed chemicals, grass herbicides, fungicides, and other adjuvants in together, the mixture in the tank can cause crop burn. This problem is intensified by warm temperatures, so use caution when spraying with a variety of products in the tank, and in some cases, a second application could be necessary. Barry Holzworth

With delayed planting this year, we are going to have a larger window between our post-emerge herbicide applications and crop canopy in soybeans. Make sure you have the proper programs in place in order to keep the weeds suppressed until canopy. For residual control, include a group 15 such as Warrant at 3 pts/acre or Dual at 1.33 pts/acre.

Be on the lookout for thistle caterpillars!  We’ll be spraying beans this week hard and these caterpillars will be everywhere.  For $2/acre, you can clean this up, and why not if you’re already making the pass?

Jacob Gubbels

Wood River

If you are gearing up to run your soybean post, be sure to scout the fields prior to ensure there are no pests that need addressed. Thistle caterpillar are showing signs of feeding. Even if you had treated soybeans, we are still seeing feeding on the lower leaves. If you are coming with an Xtend-approved dicamba product, check the label for tankmixes as they are limited. In this instance, it might be a good idea to make a sequential application of insecticide if thresholds are overbearing.

Application of a fungicide at the flag leaf on wheat has proven to be really important for keeping the wheat green, protecting the flag leaf, and for head fill.  Nexicor has been an excellent choice.  It is a 3-mode of action fungicide in one package.

If you are spraying Flexstar, remember you cannot use it two years in a row on the same field. Also, check the rotation restrictions.  Flexstar has a 10-month rotation to corn.

Timing is everything, so be proactive when protecting your winter wheat fields from diseases. Prosaro at 6.5 oz/acre or Caramba at 13.5 oz/acre are good fungicide options. Generic tebuconazole products (same A.I. that’s in Folicur) can also be considered as they are very inexpensive and good on rusts.

Even with increased rates of volunteer corn killer in the tank, we are still seeing a lack volunteer corn control in our dicamba systems due to antagonism in the tank.  My advice is to get out there and make another pass on these fields with just corn killers, AMS, and crop oil to make sure to get volunteer corn taken care of before it’s too big.   This would also be a good pass to consider including an early-season fungicide.

Jay Barnett


Corn was planted on many different dates this year.  Some got a pre on early, some just got a pre on, and in others, corn was planted with no pre.  Fields range from spotless to needing to be sprayed as soon as possible.  The question is, “Do I treat the whole farm the same or do I individualize each field?”  In most cases it would be just fine to treat the whole farm the same.  If you can get it sprayed in the next week or two, you can stop the weeds that are already coming, and because products like Callisto and atrazine will offer soil residual as well, you can keep future weeds from coming too.

Tyler Koenig

Volunteer corn has begun to make a push over the last couple of days. Make sure you’re getting out to your fields and scouting. Volunteer corn will lead to more corn rootworm next year and depreciate yield!

Ty Iverson, Travis Petty & Koty Short

Coverage is key! The cheapest component going into your sprayer is water, so make sure to add enough. Products like Liberty require at least 15 gallons of water per acre but perform even better against big weeds at 20 gallons of water.

Ty Iverson

If you’re looking for a good burndown, look at Gramoxone or Parazone. I recommend a rate of 1.5-2 pt/acre and adding AMS at 2.5 lbs/acre plus crop oil concentrate at 19.2 oz/acre.  If 2,4-D could be used, such as in prevent plant, it adds a lot of help on big broadleaf weeds.

Koty Short


You should be out in your soybean fields checking for bean leaf beetles and other pests. Silencer or a generic equivalent will work well on most insect pests for only a couple bucks per acre.

Josh Frost & Eric Butz

If you are using dicamba in your early post corn applications and you don’t get your fields sprayed by V2, plan to switch to DiFlexx. DiFlexx has a corn safener in it to protect larger, faster-growing corn plants from the adverse effects unsafened dicamba can have on them.

Eric Butz

For post-emerge weed control in corn, look at using Resicore. It contains Surpass (Group 15), Callisto (Group 27), and Stinger (Group 4), which gives you 3 effective modes of action.

Josh Frost


This week, our area will have highs of 70 and lows around 50. If small weeds or low weed pressure will allow you to wait on a Liberty pass, you will get better results on warmer sunny days. Also, use no less than 3 lbs/acre of dry AMS added to the tank mixture.

Chris Kassube

Kyle Wiese, Alan Williams & Jason Leyendecker

Alfalfa weevil larvae infestations are heavy.  A pyrethroid chemistry such as Silencer at 3.84 oz/acre is a very good choice for control.

Alan Williams

Kochia has some pretty good size to it, and it might be tough to catch all the growing points with Liberty alone. Adding a deposition aid like Latch at 4 oz/acre will assist the Liberty by penetrating and sticking to the thick mats of kochia.  Also focus on getting smaller to medium spray droplets and using 20 gallons of water per acre to improve coverage.

Kyle Wiese


If you are still finding some patches of kochia that slipped your pre-emerge application, we have options. DiFlexx works well to pick it up in corn.  Liberty for Liberty Link soybeans or Engenia/Xtendimax labeled for use in Xtend soybeans will take it out.

Jeremy Nedved

If you are spraying fungicide on wheat, check for bugs. Aphids have been spotted in the area. Insecticide is cheap and has a great return on investment.

When spraying, watch out for washouts in the fields due to the heavy rains we been having. There have been reports of sprayer damage.

Russ Werning

If you are seeing heavy broadleaf pressure in your conventional corn fields, you can use Status at 5 oz/acre plus 2.5 lbs AMS and 1 quart of NIS/100.

Common root rot and fusarium were detected recently in some lentil fields.  Reduction of plant stresses such as compaction, pH extremes, soil characteristics, nutrient issues, and ideal growing conditions are important for reducing the impact of this root rot/damping off complex.  One more reason why we need to really look at liming our low pH soils.

Jamie Rovey


I’ve been seeing a lot of marestail that is about to bolt. 2,4-D at a high rate with dicamba is a good option. Once it has bolted, Sharpen is a good option at the 2 oz rate.
