South Dakota

Aberdeen, SD

Make sure you are getting your pre-herbicide on- this is really critical for optimum yields.

Baltic, SD

When looking at a field of corn that had frost, look at what part of the plant was actually damaged. The growing point is below ground until the 5 or 6 leaf stage. The fields I have scouted had minor damage to the first two leaves, but the whorl is healthy and growing so it should not have an impact on yield.

Centerville, SD

If you’re seeing volunteer alfalfa in your corn fields, Roundup spiked with Stinger or dicamba will take care of it. Just be aware of the temperatures when you spray herbicides. With the cool, cloudy weather, plants aren’t growing as actively so herbicide intake will be limited.

Kelly Gates

With cool and damp conditions in the mornings, wait until the leaves are dry and temperature is above 50 degrees. Waiting until mid-morning or until conditions are fit will provide better uptake leading to better results.

Jeff Shumaker

If you are planning to rotate to winter wheat from beans, Warrant may be your better option for early post on beans due to having a 4 month rotational restriction to winter wheat.

Freeman, SD

Thistles are starting to emerge in the pastures around the Freeman, SD area. 24-32 oz. per acre of Grazon Next HL (the old Forefront HL) is a great option for Canada thistle, musk, plumeless, and bull thistle control. No additives or surfactants are needed either—just the product with 10-15 gallons per acre of water.

Huron, SD


Wet weather has made conditions very favorable for a rust breakout in small grains. The best approach to minimize losses from this disease is to protect your crop before the visual signs of rust appear. A fungicide with 2 modes of action is best.

Kimball, SD


With the rush to get soybeans planted, don’t forget to put your pre emerge herbicide down. Many weeds are nearly impossible to control in crop (like kochia) and your only real shot of great control is with a pre like the Authority products or Valor plus metribuzin.

Roscoe, SD

Temperatures are warming up to the degree farmers in the area are resuming spraying operations. Weeds and crop have both been stressed, so be sure to add AMS and Non-Ionic Surfactant to Roundup applications to achieve good uptake by the plants.

Watertown, SD

If you have problem weeds in your pastures such as gumweed, wormwood, or goldenrod, use Chaparral at a rate of 3.3 oz. per acre and don’t forget to add 1 quart of NIS for every 100 gallons of water.

Russ Werning

If you are having trouble with kochia, marestail, or other tough weeds in your spring wheat, take a look at using WideMatch at 1pt. per acre and NIS at 1quart per 100 gallons of water for great control.

West Point, NE

If you have beans planted and they are emerging and you still haven’t gotten any residual out yet, Warrant at 3 pts per acre is a good option.

Breckenridge, MN

Scout your wheat for insects prior to spraying your herbicide and fungicide. A half rate of Warrior II or equivalent will control most pests and will tank mix fine.

Fairmont, MN

Farmers have some concerns in the area about frost on the soybeans. We believe that we are seeing slower emergence because of the cold, wet weather and that we did not actually lose any crop to the frost. In a few days we can better assess if we need to switch gears and consider replant options.

Steve Draper

DiFlexx is a new dicamba chemical that has been paired with Bayer’s CSI safener allowing it to be used on corn much taller than what dicamba has been used on in the past. If you like dicamba and are looking for a product similar, DiFlexx would be a great choice for you. With the safener and a wide spectrum of weed control, DiFlexx is an excellent product.

Mike Bates

Adding Stinger to your post herbicide application in corn at 5 oz. per acre is a great option if you are having issues with giant ragweed in your fields. Keep in mind, however, that if you used SureStart or TripleFlex both those products contain Stinger, which should only be used once per season to avoid carryover and injury of next year’s soybeans.

Hancock, MN

Small grain growers in the area are concerned about higher than normal disease pressure potential this year. A cheap option to boost disease control would be to spike in 2 to 4 oz. of Tilt or Bumper into your planned Headline, Evito or Equation pass for better weed control.

Adam Gibson

When it finally dries up, producers in the area will start planting their dry beans. Start the season out right by incorporating a good pre emerge herbicide into your soil like Sonalan at 2.5 to 3 pints per acre.

Janesville, MN

Remember when you’re spraying pasture ground to consider if it will be turned into crop ground in the future. Some pasture products (like Tordon, Milestone, and Cimarron) have a lengthy carryover to certain crops. Another thing to consider are grazing and baling restrictions.

LeRoy, MN

The sun is shining! However, just because the sun is shining doesn’t mean it’s a good day to spray. Remember that according to the weeds it’s still very cold. Give them a couple days to get back on track before you wipe them out. If you are putting on a pure residual product that’s no problem. Get to it.

Marshall, MN

Gramoxone at 2 pints per acre will take care of any growing weeds in your bare fields that will be soybeans. Gramoxone has no residual but should be left on the field for a few days before digging into the ground again. Coverage is the most important.

Mike Homandberg

feirce soybeans

The past weekend’s hard pounding rain has caused some crusting concerns. Some of the later planted soybeans may be having a tougher time coming through the soil surface. Rotary hoeing may help if the soybeans have not emerged through.

Olivia, MN

If you still have soybeans to plant, consider using a product like TJ Micromix. It supplies a blend of 7 secondary nutrients and micronutrients that are readily available for this cropping season. It may be applied in furrow or foliar at a rate of 1 to 2 quarts per acre. Many trials have shown yield increases at 3-5 bushels per acre.

Troy Walker

Many growers are getting out spraying cover crops and some corn. Don’t forget the adjuvant or cut it to save money. Adjuvants make the chemicals work better, especially in cooler temperatures. Also adding real AMS helps to condition the water and provides some nitrogen and sulfur value.

Ulen, MN

With this recent rain event we’ve had along with the cool temperatures remember to allow a few days for conditions to improve before you spray your herbicides. Herbicides work best on actively growing weeds that are not under temperature or water stress.

Winthrop, MN

Crops are under stress due to cold and wet soil conditions. So, when you start spraying Roundup on early season weeds, adding MegaGro at 2 oz. per acre will get Roundup through plants quicker and increase your overall plant health.

Dean Christiansen

If you used a product like QuickRoots corn or beans, now would be a good time to go out in your fields and do some root digs. There may not be much of a physical difference above ground, but below the surface you should be able to see a significant difference in root hairs and root sizes.

Great Falls, MT

A great tank mix for grass and broad leaf control is 12.8 oz. of Huskie and 3 oz. of Rimfire Max. Remember to remove the MSO and use NIS at a quart per 100 and AMS at 1.5 lb. per acre instead.

Shawn Ostberg

Leafy spurge is very visible now and quite susceptible with it warming up. Some growers like 16 oz. of Tordon 22k with 4 oz. of Distinct. A straight shot of 32 ounces of Tordon on the weed patches will do the trick actually killing leafy spurge for good.

Sidney, MT

Many producers are getting geared up for spring wheat spraying. Some are talking about Russian thistle as their main problem. Using LV6 with your tank mix can improve control.

Rockwell, IA

We’re heard reports of cutworm activity in the area. Moths were blowing up earlier this spring with the strong winds out of the South and laid eggs that are hatching now. Keep scouting your fields and treat with $2 to $3 worth of a pyrethroid insecticide like Silencer when needed.

Sheldon, IA

There are a lot of corn fields that are looking pretty rough from the cold and wind. Don’t get too excited. Take a look at those fields tomorrow, after a few days of sun and they should start to turn around.

Buhl, ID

Weed control in pumpkins can be challenging. Sandea herbicide can be used either pre emerge or early post emerge for control of broadleaf weeds and nutsedge.
Zach Zacharisen

If you have thistles in your corn field add some Stinger to the tank when you spray to control them. Just be cautious of the rotational restrictions.

Hillsboro, ND

With the cold temperatures and frost we’ve had, it’s a good idea to wait until the small grains recover to start spraying herbicide. The chemical will also work much better in warmer temperatures.

Hurdsfield, ND

We know that weeds decrease yields in crops, and the same is true for pastures. Try something like GrazonNext HL, a premix of Milestone and 2, 4-D, at 1.5 to 2 pints per acre to increase your grass production and stocking rates.

Emily Kline

Lisbon, ND

A lot of spring wheat in the area will start getting sprayed soon. Now is the time to scout your fields to see if you need a grass and broadleaf control treatment such as Huskie Complete, or just a broadleaf control product like Huskie. Also, scout those fields for harmful insects so you know whether or not to add an insecticide.

Mohall, ND

With a lot of prevent plant acres from last year, remember to double inoculate soybeans that are going on ground that hasn’t had soybeans for the last 3 years. Tag Team Granular is a good option to go along with a liquid seed treatment inoculant.

Charlie Adams

We’re seeing some small kochia and volunteer sunflowers in barley fields. After the frost give your crop 7 days to get back on the right track and spray with Brox-M, WideMatch and Evito for an effective kill that will be gentle on the crop.

When putting liquid starter down, consider mixing some water with it. This will increase your volume per are and give you more even placement of the fertilizer.

Wilton, ND

Fertilizer losses need to be considered after recent heavy rains. Sulfur losses will occur most likely on sandier soils, hilltops, and inclines. Canola, corn, and small grains are crops that are most vulnerable to deficiencies in sulfur. Even if it was applied pre-plant or at planting, supplemental sulfur should be considered.

Bertrand, MO

Corn in our area doesn’t look too bad, but farmers may consider using a good fungicide right now to help protect their crop. A good time to apply a fungicide on corn is the V6 – V7 growth stage. Fungicides are mainly preventatives so don’t wait too late to spray. Some fungicides to consider are Stratego YLD at 3.5 oz. per acre, Fortix at 3 – 5 oz. per acre or Quilt Xcel at 10 oz. per acre. Remember some rebates may apply with some products.

Farmington, WA

For hard to control bedstraw in spring wheat, Starane Flex at 13.5 oz. will have control with two modes of action. It is best to catch this weed before it gets past the fourth whorl.
