Augusta, AR
Armyworms in wheat at this time are below threshold. We are getting good emergence on corn and soybeans. There is scattered hail damage to varying degrees in all crops. — Perry Galloway

Rice is up 1-2 leaf, 80% planted. Residual herbicides are working well where applied; barnyard and broadleaf signal grass are coming thick where herbicides were not applied. Will have to spray and cleanup when surface rain water runs off with Propanil and a residual herbicide. — Joey York



Buhl, ID
With the cooler ground temperatures, it is a good idea to run a seed treatment like invigor8 on your corn seed. This will give your seed more energy to get out of the ground and aid with uniform emergence. — Van Wiebe



Georgetown, IL
Seed treatment, in-furrow fertilizer, and in-furrow fungicide are making farmers money this spring with the recent cold weather and heavy rains. Apply 1-2 gal/acre of AgroLiquid’s Pro-Germinator plus Sure-K, along with 1-2 qt/acre Micro500. Root zone banding in 30 inch row beans can result in seedling injury at rates above 3 gal/acre in light textured soils. The risk goes down in 15 inch rows, and there is little chance of seedling injury with soybean fertilizer programs in drilled soybeans. — Evan Zimmerman

Princeton, IL
It is not uncommon for corn to take 2-4 weeks or more to emerge. Soil temperatures and ambient temperature all play roles in the time it takes. As long as the seed is not damaged and the soil is not crusted, the plant will likely emerge just fine. — Mike Denton

Don’t be discouraged about the cold and wet weather lately. There still will be good days for planting once the fields dry up. Take this time to check in with your agronomist to go over the crop planting plan or even get a head start going over situations on your post-herbicide plan. That way once fields are fit again, everything is in place to have a less stressful spring since the planning is already done! — Matt Denton

With corn planting wrapping up quickly, soybeans will be going into the ground. Hefty Complete seed treatment will help ensure beans get off to a great start in the cold damp conditions we are having. — John Becker



Rockwell, IA

Don’t skip the pre-emerge herbicide this spring! Resistant weeds are on the rise and the best solutions for control often come in the pre-emerge herbicides. Even before Xtend and Liberty Link soybeans, the pre-emerge herbicide offers a major advantage in weed control and yield. — Tim Nuehring

Sheldon, IA
With the colder soil temperatures, many farmers are concerned about their seed. By doing the little things right like adding a fungicide seed treatment, QuickRoots seed treatment, pop-up fertilizer, and a fungicide in the furrow, you will help that seed emerge much quicker and with more vigor. — Adam Sauer

Marestail flushes are starting to bolt on no-till acres. Get yourself prepared and ensure your burndown recipe is adequate for aggressive plants that overwintered. For burndown, consider using 2 modes of action if resistance has been observed or plants get 4+ inches in height. This spring, Sencor; 2,4-D; Gramoxone; Roundup; and Dicamba are all potent options. Read labels and know your plant back restrictions before spraying. — Connor Majerus

One misconception about seed treatments is that you are only protecting the seed. Seed treatments also protect seedlings as they start to emerge. Soybeans in particular have some diseases that set in early and can rob yield before a plant reaches V1 growth stage. Phytophthora and sudden death syndrome are two examples of diseases that can have a major impact on yield, but can be greatly reduced if seed is treated at planting time. — Nathan Kloft



Breckenridge, MN
With all the cold, wet weather this spring, make sure to throw some fungicide in on your first wheat spray to protect against disease! Tilt at 2 oz/acre, or a generic Tilt, is a great way to start protecting your wheat! — Tia Johnson
Fairmont, MN
With the early, warm temperatures, a lot of weeds have emerged already. Most should be taken out with the field cultivator in conventional tilled fields. If in no-till or strip-till, a burn down should be used. — Evan Oberdieck

Hancock, MN
There are a few growers in our area putting corn in the ground now. With the cold and wet conditions we are seeing, it is important to consider putting a fungicide and insecticide in-furrow to protect your seed. Products such as Temitry LFR or Manticor would be two very good options. — Aaron Giese

There have been widespread reports in the area about winterkill in existing alfalfa stands. The worst cases are in 3 to 4 year old stands in low lying areas of the fields where alfalfa may have had standing water suffocate it. Evaluate your alfalfa by digging up one square foot of plants and count the “good” healthy stems. Damaged crowns and roots may have short regrowth of stems (count only half of these). A count of 50 stems/square foot is the minimum you should have for a good crop. — Adam Gibson

Janesville, MN
With the cooler soil temperatures we are seeing this spring, here are a few tips to consider before planting. Pick a good variety with an excellent seed treatment, use a biological like QuickRoots, and an in-furrow fertilizer with a fungicide for a great way to get your corn off to a great start. — Todd Traynor

LeRoy, MN
We have seen some amazing results with RyzUp SmartGrass in pastures. With these cold temperatures, it really promotes fast growth. The grass grows so fast it looks lighter in color, but it is an easy and cheap way to get some growth early if some of your pastures are having a hard time taking off. — Grant Lunning

Olivia, MN
Root growth and nutrient uptake are important for good emergence and vigorous plants. Fertility is key but microbial activity also plays an important role. Nutri-Cycle is a new product that contains 21 biological organisms and can be applied in-furrow with water or starter. Amongst other benefits, these organisms improve nutrient uptake, increase germination rates, and release organic acids. This is a good product for your farm, especially on areas of high pH. — Tony Hagen

There are many acres of sugar beets planted already and a percentage of them have emerged. Be scouting them for vigor after these cold nights so you know if you have any frost damage. Also be looking for cutworms and other insects that may be chewing on the leaf tissue as we have heard reports of chewing already. An earlier than normal insecticide treatment may be warranted this year. — John Scheibel

If you are concerned about having giant ragweed in your soybean fields this summer, consider using Authority First as your pre-emerge herbicide. — Aaron Spronk

Ulen, MN
This year our corn planting dates will be later than the last couple of years. With that in mind, planting as fast as you can when you get in is not the answer. Be patient when you get going, seed depth and ground speed will be your greatest asset for quick emergence in corn. A general rule is 1.75 to 2.25 inches for depth. I would like to be no deeper than 2 inches. Slower speed will give you accuracy and consistency; your best yields come with emergence of all plants within 12 to 24 hours of each other. — Greg Peterson

Winthrop, MN
With very cold and wet soil conditions this spring, you may want to add a microbial soil inoculant such as QuickRoots or NutriCycle to your corn acres. This will help decrease stress and increase early nutrient uptake leading to the potential for higher yields. — Dean Christiansen

With the cool and wet temperatures we have been experiencing, it would be a great idea to put a fungicide in-furrow with your corn. Products like Capture LFR + VGR, Temitry, and Manticor will really help with seedling vigor and also protect against insects. Each of these can also be mixed into your liquid starter. Protecting the seedling in these conditions is very crucial. — Tyler Gasow

With temperatures looking to stay on the cold side for the next week, putting an insecticide and fungicide in-furrow will help to protect the seed while it sits in the soil. Capture LFR + VGR is a great option for an insecticide plus a biological for about $8/acre. Temitry LFR and Manticor are premixed products containing Capture LFR plus the active ingredient from the fungicide Headline for $14/acre. All of these products will mix with your starter and should have a good return on investment as it doesn’t take many bugs or much disease pressure to start seeing a loss of up to 10 bushels. — Matt Vogel



Bertrand, MO
For an early post-emerge application in Roundup Ready corn, you might consider using PowerMAX at 32 oz/acre with Impact at 0.5 oz/acre for early weed control. — Albert Duenne

Most of the area wheat has completely headed. Insects are present in a number of fields. An application of fungicide plus insecticide has been (or will be) applied when the head is at about 10 to 15% flowering. — Albert Duenne

Hayti, MO
When burning down behind your rice planter, it may be good to add 2 oz/acre of Sharpen to your Roundup and Command. It will help with pigweed, marestail, and morningglory control. Remember to add 1 pt/100 gal of MSO to the acre for best results. — Eric Luye



Sidney, MT
With the cool and freezing conditions at night, weed control may not be the best. To improve weed control with glyphosate, increase the glyphosate rate by as much as 50% (follow the label for max rates), increase the amount of AMS used from 8.5 lbs/100 gal of water to 17.5 lbs/100 gal of water, wait 48 hours from last frost, and allow the daytime temperatures to get above 50 degrees. — Chester Hill



Laurel, NE
Winter annuals like marestail have gotten off to a good start this season. There also seems to be more downy brome than in the past. Be sure if you are no-tilling you know what kind of weeds you are after before you load the sprayer. — Kody Urwiler

With the cooler temperatures you may want to consider adding some Sharpen or Aim to your burndown. — Rusty Reifenrath

West Point, NE
With a cool and wet spring, make sure you are using complete seed treatments to protect the seed and achieve faster emergence. — Jared Steffensmeier

Marestail week: I will be focusing on marestail this week. I will be trying to cover all your options each day this week starting from the best to worst options. Soybeans: The best option is to plant Xtend or Liberty beans! You can use Xtendimax and Liberty, respectively, for burndown with no planting delays. Corn: Verdict – I like 12-14 oz/acre with 1 pt/acre of MSO. This is the easy choice in corn. — Jacob Gubbels




Hillsboro, ND

Even though it is later in the season, we still recommend putting some type of seed treat on your small grains while starting up the planting process again. Cool, wet soils are ideal for diseases, so at the very least put a fungicide seed treatment on. — Ryan Pierce

Hurdsfield, ND
Right now is prime time for RyzUp SmartGrass applications in pastures. RyzUp will get the grasses growing despite the cool and wet conditions we’ve been experiencing. A 0.5oz/acre rate paired with 1 gal of 28% and some NIS can be applied by ground or air. — Emily Kline

Lisbon, ND
When planting corn into cold, wet soils, using a fungicide plus adding insecticide in-furrow along with a pop-up fertilizer will help get your corn off to a great start. — Adam Ladwig

Mohall, ND
In early seeded spring wheat, we noticed Japanese brome in sunflower stubble. Even though our area temps are still cold, spray 22 oz/acre of Roundup and 0.2 oz/acre of Olympus. It is important that you do this in order to suppress the Japanese brome or cheatgrass as early as possible. — Ron Hefta

Wilton, ND
With these extremely cold soils we are planting into, please consider a seed treatment program for all crops. This is such a small insurance policy for your whole crop income. — Jamie Schurhamer



Aberdeen, SD
For those of you planting corn in these cold conditions, protect your seed with biologicals and in-furrow fungicides. Products like Xanthion at 4.8 oz/acre give you 4 oz of Headline and 0.8 oz of Integral, and can provide seedling protection and a positive ROI in these cold, stressed conditions. — Kalen Kjellsen

Small weeds and grasses are beginning to show through, especially on ground blackened in the fall. Be sure if you are a ways out from planting that you do some quick burndown with 24 oz/acre of PowerMax and 1-2 oz/acre of Sharpen. — Justin Hanson

Baltic, SD
May has officially arrived and weeds are starting to pop out of the ground like gangbusters! If you are planning on doing a burndown with 2,4-D, Banvel, Sharpen, Gramoxone, or Roundup, wait for warmer weather. These products are cold sensitive and will lose activity in cool to cold conditions. It is in your best interest to wait to spray these products until the temperature warms back up later in the week. — Tyler Koenig

Winter annuals and biennials are getting some size to them. When applying burndown products, make sure you adjust the rates to account for the larger plants in order to get great control. — Mike Drey

Once corn planting gets back into full swing, we will be dealing with cooler and wetter soils. Products like Manticor LFR and Temitry LFR that contain both an insecticide and a fungicide will help that young seedling through this stress. — Lee Fischer

Centerville, SD
With cold soils and corn planting starting in the area, the seed could be off to a slow start. To help protect your investment, I recommend Temitry LFR. This product contains Capture LFR to protect against insects in the soil and Headline to protect against early season disease. — Travis Petty

Make sure you are watching for emerged weeds in fields that have been tilled. With spring rainfall, some are rooting back down which happened last spring as well. You may want to consider a burndown now so they do not get too big to control later on. — Tim Brouwer

Cool wet weather in some areas has plagued corn planting and made conditions conducive to seedling diseases. If you’re not putting a fungicide in-furrow with your starter this year, you might want to consider it. Headline, for one example, helps protect your seed and typically increases yield to boot! — Ryan Kusser

I’ve noticed a few stands of field pennycress in the area. A pre-emerge herbicide program with glyphosate would be a great option in either corn/soybeans, along with conventional tillage. Please note when this winter annual heads out, it can produce up to 20,000 seeds and remain in soil for many years. The rosette stage in the fall is the best time to kill it with a good burndown application. — Peter Strom

Freeman, SD
When burning down no-till acres, make sure you are spiking in another product with your Roundup. On the tough to get weeds like kochia, pennycress, and mustard species, use Aim at 0.75 oz – 1 oz/acre + 1 gal/100 gal of COC/MSO for additional burndown. — Matt Zilverberg

Gettysburg, SD
If you are doing burndown and seeing lots of little kochia, throw in Aim at 1 oz/acre plus MSO. — Kyle Hawkinson

Huron, SD
Before applying your soybean or corn pre’s this spring, make sure to do a field scouting trip. Many different weed species are starting to emerge besides just kochia. Winter annuals, broadleaves and grass pressure may warrant adding a burndown component to your pre-plant herbicide. Knowing the pressure and type of weeds will make your burndown choices easier and add value to your application trip. — Garritt Dykstra

With the corn planters starting to roll in the Huron area, remember to check planting depth often. 1.75 to 2 inches is the ideal planting depth. — Norland Hofer

Kochia is growing with a vengeance! If the acre is going to a no-till Xtend soybean seed, your choice of control can be 22-44 oz/acre of Xtendimax with VaporGrip, NO AMS/nitrogen source in the tank EVER with this product and control will be great. — Alan Williams

Kimball, SD
It’s always important to get a pre-emerge herbicide on any crop you are growing. Not only does it stop weeds before they can come up, it also helps fight resistant weeds. Some of our favorites for the Kimball area are Authority MTZ or Valor on beans and Resicore or Balance Flexx on corn. — Jeremy Nedved

New Underwood, SD
We’re starting to see a little disease show up in our wheat. To prevent it from getting any worse, 2 to 4 ounces of propiconazole is both effective and inexpensive. — Tyler Price

Watertown, SD
Fungicide seed treatment is a must this year for preventing diseases in your spring wheat. Applying Stamina at a rate of 0.4 oz/100 lbs of seed will provide great control against fusarium seed rot and fusarium crown rot as well as other diseases. — Russ Werning

Putting a seed treatment on your soybeans is very important for their early growth. Diseases like pythium, rhizoctonia and phytophthora are known to rob yield in this area. You can control them with products like Apron, Acceleron and Intego seed treatments. — Beau Wensing



Farmington, WA
For the first time in a month, the weather looks good for the 10 day forecast. Let’s make the most of it while it lasts. — Jamie Rovey

Quincy, WA
In cool wet soils, starter mix formulations become a growers best ROI. Phosphorous is important, but balanced nutrition will provide a successful environment for your seed. — Dave Dye
