We got a few early planted corn fields on the books for pre-tassel nitrogen application today; maybe we can get it out in front of the rain Saturday night.  With more soybeans getting planted today and more rice going to the permanent flood, we are moving ahead with our crop here in Arkansas.  It’s been slow and wild, but we are making progress now!

With the forecast for June calling for cooler and wetter than normal weather, now is a great time to sit down with an agronomist and discuss options for fungicide. Fungicide and insecticide in soybeans is something we have seen a great response from on our farm. I would recommend every farmer to at least try it a little bit on their farm in a side-by-side trial to see the results.

Tyler Smith


6 oz/acre of Zidua Pro was applied on April 24 in the picture taken a month later on May 24.  You can tell right where I ran out half a pass short.  That is unworked/unplanted ground that has been continually getting the rains as well.


Kyle Bickett

If you run row cleaners on the planter as we do, be sure to scout your fields even if you have a good dose of pre-plant applied. In some cases of softer ground, the row cleaners will “furrow” and move the chemical out of the row. This leads to weeds in the row which are hard to see from the road.

Mike Denton

Many beans will be going in the ground as soon as fields are fit.  A recent study from the University of Arkansas points to a substantial yield increase from using inoculant even in late planted beans.  If your beans have been treated longer than 30 days, we would encourage you to add a dry inoculant, like ROOTastic, at planting time.  After 30 days, about 90% of the rhizobia bacteria have died on unplanted seed regardless of the brand of inoculant or extender used.

Soybeans in the area are showing signs of pythium root rot.  This is caused by having soils that are cool and wet for an extended period of time.  Some fields only have a few spots, but other fields may require replanting.  Be sure to go out now into your fields and evaluate the stand while you have time to react.

Adam Sauer

With fields starting to dry, I’m seeing quite a few farmers out in fields doing root digs on the crop. Most are looking to see how the root system is starting to take shape, but don’t forget to check to see if there are any insects like cutworms, wireworms, or rootworms around yet. Make sure you do multiple digs per field, in different rows, and check places in between the rows to get a better visual of the whole field rather than one point.

When spraying before a rain, be aware of the rainfast time for the chemicals you are using. Some products need to be applied at least an hour or more before rain comes.

Tia Johnson


It appears that it will take a few more days of warmer (hopefully much warmer) temperatures to get some better emergence showing up. Farmers in the area are noticing that bean fields with treated seed are definitely showing better performance through this cold, wet planting season. Pre-emerge herbicides are looking very good this year as well.  If you did not get a pre down on your fields, there are still some options for good knockdown and residual weed control but they must be done soon for best results when weeds are very small.

Now is the time to add 8 oz/acre of dicamba with your TripleFlex and SureStart on spike to V2 corn.  This corn that has been planted for 2 -3 weeks has many tiny weeds just ready to explode.  Banvel is an option that not only provides knockdown, it is very water soluble and provides short-term residual until a rain can activate your other pre-emerge chemical.

Adam Gibson


I have been seeing a few thistle patches on the edges of fields.  A lot of growers will spot spray with a combination of 2,4-D and Stinger for control in these areas.

Ray Johnson

Dave Lunning & Grant Lunning

The big thing on a grower’s mind now is, “Can I spray the yellow corn?”  I tell most of them no. Wait until the corn or soybeans get some color back. The crop is already under enough stress, and the herbicide will only add to it.

Grant Lunning


Your nitrogen levels could be less than you think because of the recent rain. High moisture amounts can cause nitrogen levels to move out of the plant root zone.  Side dressing 28% at the V5 stage might be a good idea this year. Soil or leaf tissue tests can give you a more accurate reading of nutrient levels to ensure you are not over-applying.

Aaron Spronk & John Scheibel

Are you planning on using Xtendimax or Engenia on your Xtend soybeans this year? Most growers planting into last year’s corn stalks are finding some volunteer corn and will need to treat for that as well.  If you are planning to tankmix a volunteer corn killer in the tank, make sure to check and  There are only a few products that are currently approved for tankmixing.

John Scheibel

With moderate to heavy weed pressure this spring, we’re fielding a lot of calls about adding a dicamba product to early corn tankmixes.  You can spray Clarity from spike to 8-inch tall corn.

Aaron Spronk

Growers who did not put a pre down in their corn are starting to see some weed emergence. If this is you, start getting ready for an early post application and including a residual product such as Harness or Outlook.

Tony Hagen

Thief River Falls

If you are planning on spraying Huskie or Huskie Complete, keep in mind that they both have a rainfast of 1 hour and restricted entry interval (REI) of 24 hours.  If you are going to spray Rimfire, that has a rainfast of 4 hours and an REI of 12 hours.

Rachel Klein

When scouting spring wheat in our area, I have come across white cockle in a few fields.  There are not many herbicide options to control it.  One option is adding Affinity Tankmix at 0.75 oz/acre in your wheat herbicide portfolio to control white cockle.

Fields in our area are now starting to dry out. When you can, scout your fields for a stand count to see if replanting is needed in any areas.  Contact your seed agronomist to make sure you can get varieties of corn or soybeans needed.

Dean Christiansen

I’ve noticed a lot of yellow looking corn while driving along the countryside. This is mostly due to the cooler weather and lack of sunshine. No need to panic, if you notice that your corn is on the yellow side, with a little heat and sunlight, the corn should turn take off and start turning green.

Tyler Gasow

When you are switching herbicides in your sprayer tank, the most important thing to do is to make sure the previous product gets completely cleaned out to avoid any crop injury.  Farms I’ve visited are often using a tank cleaner such as Erase to help in getting those hard to clean chemicals out of the spray tank and booms.

Matt Vogel


Albert Duenne & Kara Wolford

A few farmers are still applying a burndown for their soybeans. There are a ton of different combinations they are spraying.  Some are using Afforia at 2.5 oz/acre, Powermax at 32 oz/acre, and Gateway Plus at 1 gal/100gal of water.

Albert Duenne


When applying your fungicides in peanuts, remember to always use sufficient water volume (15-20 gal/acre) to penetrate the canopy.  Also, applications at night when leaves are folded have been shown to improve fungicide penetration into the lower canopy.

Barry Gilmore

Thrips are showing up in cotton fields around our area, 0.5 lbs/acre of acephate applied when damage is noticeable should answer the problem.  Avoid tankmixing acephate with certain herbicides such as Staple, Warrant, Dual, and Liberty as foliar burn may occur.

Eric Luye


Danny Stevens, Christie Irions, Eric Luye, Barry Gilmore, and Keith Griffin


Heavy cutworm damage was noticed on peas at certain locations in the Sunburst and other Golden Triangle areas of Montana. Cutworms are the larvae (caterpillars) of numerous species of night-flying moths in the family Noctuidae, which are usually active for feeding during the night. The larvae are called cutworms because they cut down young plants when feeding on stems at or below the soil surface. Cutworm damage occurs early in the season when plant seedlings are small and have tender tissue. On a regular basis, monitor your fields, particularly during late afternoon and evening when cutworms are active, so you can notice their movement when they are initially present.

Chester Hill

Pea leaf weevil has been reported in Eastern MT this spring, below is a link to learn more.  Be out scouting fields.  Insecticides can be used to control the weevil.

I’m seeing some corn that has come up before the pre-herbicide was applied.  You may need to change your plan to a different program to make sure you don’t have crop injury. Resicore is a nice fit we’re seeing area growers utilize in these situations for good burndown and residual.

If you have fields that are tilled and still need a pre on, Anthem Maxx is an option for residual and some burndown on any small weeds that are starting to come up.

Jared Steffensmeier


Dry conditions have resulted in growers questioning their soybean pre’s.  Soybean pre-herbicides depend on at least 0.5 inches of rainfall to fully activate and reach their full potential.

Adam Ladwig, Brian Weight & Spencer Schultz

Many guys are busy spraying soybean pre-emerge herbicides, but they say they’ll have to turn right around and spray their corn fields as soon as they’re done.  Some corn fields are already starting to dirty and will require a herbicide application in the next few days. When spraying this early, farmers prefer to use a residual product such as Resicore along with Atrazine that will get them through to crop canopy. Without the residual, the weed control has not been good enough.

Spencer Schultz


I looked at a field that was sunflowers last year.  The intention of the farmer this year was to spray an SU (sulfonylurea) herbicide for broadleaf control, but there are enough volunteer sunflowers out there that an alternate mode of action is called for.  A tankmix of Quelex and WideMatch really do a nice job at controlling volunteer sunflowers.  Make sure you’re changing the mode of action for killing last year’s volunteer crop.

I was recently out in a corn field that had some patches of hairy vetch growing. The field was sprayed with Verdict as a pre-emerge, but Verdict has no activity on vetch. A product that is a growth regulator, such as Stinger or Banvel, will more than likely have to be used to control this weed.

Tanner Johnson


The ditches and pastures are loaded with leafy spurge this year – as identified by the yellow flowers in patches as they spread by pressurized ejection of seeds from the flowers and rhizomes underground.  The best product to hit them with is Tordon 22K at a labeled rate.   It provides residual and knockdown against spurge and thistles, too.  If you want the best long-term control, you need to follow this fall with another application as that will weaken the plants and give the best reduction in stand.

I have had several farmers this week ask about what their options are if they do not get their pre-emerge herbicide on their beans.  The pre-emerge herbicides along with a burndown to kill any weeds that may be up is still your best choice. I know it will be hard to let the planter sit and spray on the pre now, but that’s what needs to be done.  The post soybean products are ok at best, especially if you are not using Xtend or Liberty traited beans.  Plus, there are some restrictions going to corn next year if the timing is late.  Get your spraying done now and then put your seed in the ground.

Ryan Kusser


I am getting questions on Liberty. When using Liberty, make sure you have a lot of water, as coverage is critical. 15-20 gallons of water, 2-3 lbs/acre of AMS along with 29-36 oz/acre of Liberty will give you good control over most of those tough to kill weeds.

I had a grower ask if it is still necessary to put on a fungicide and insecticide seed treatment. I would say yes, it is important because it protects the seeding and helps with insect control in early growth.  Growers are finding wireworms and other insects when digging, and wet fields are showing injury from pythium and other diseases right now, too.

Norland Hofer

With a substantial amount of wind in the forecast, growers are picking up drift retardants in addition to the other adjuvants needed.  One product that seems to be growing in popularity is Intact, which is a drift retardant as well as a deposition aid.  It’s designed to help reduce surface tension between the cuticle and the herbicide, and help the herbicide remain on the leaf.  The use rate for Intact is 2 qts/100 gal of solution, and from what I’m hearing it’s working well with a variety of herbicides this year.

If you have not sprayed your wheat acres yet, make sure you determine the growth stage before applying any herbicide program.  Huskie, for example, can be sprayed up to but not including the flag leaf, while WideMatch can be sprayed up to AND including the flag leaf.

Tyler Price


When you are getting ready to spray your post-emerge herbicides, be sure to have all the proper adjuvants. The adjuvants play an important role in product utilization and getting a good kill. There have been several farmers who have had to miss out on some good spray hours because they had to run back to town to pick up the adjuvants they forgot.  Also, cool weather may require a different adjuvant than when things warm up.

Beau Wensing

When spraying Liberty soybeans, farmers who have been using the system for years say to keep your rates at 32 oz/acre and always use AMS at 3 lb/acre with very warm weather for best results.

Jack Beutler

Rust has been spotted in some fields around Liberty Butte.  Growers that applied fungicide a month ago need to apply another time as the residual protection from their previous application has worn off.  With warmer conditions over the next few days, rust could continue to spread quickly.

Jamie Rovey


Cheatgrass is starting to show its ugly head this time of year, and although it’s too late to do anything about it in-crop, if it’s headed out, it’s a great time to showcase the advantages of Clearfield technology. There continues to be more Clearfield wheat varieties that are well suited to our area. With the 2 gene varieties, there is no reason to have dockage for jointed goatgrass or feral rye anymore. 6 oz/acre of Beyond with MSO (on 2 gene wheat) is a potent combo when going after rye in winter wheat and will smoke any cheatgrass that is there as well. Coverage is important.  Growers I talk with have best results with 15 gallons/acre minimum.
