Centerville, SD

Weather this year has led to good conditions for disease and insect growth. Applying a fungicide like Priaxor along with an insecticide like Silencer has a synergistic effect and has been shown to produce a good yield response.

John Shubeck

Continue to scout your bean fields. Septoria Brown Spot is showing up in a lot of fields. With most fields in the general area flowering, beans will soon be at the stage where a foliar fungicide treatment will be beneficial (R2-R3).

Freeman, SD

We’ve had some scattered hail storms come through the last few weeks. Remember that using a fungicide such as Fortix, Priaxor, or Stratego YLD on your corn and soybeans will help protect some of the damaged stem and leaf tissue on your corn and soybean plants. Plus, they will tankmix with about any herbicide out there, so you can do almost everything in one post emergent pass.
Josh Horstman

Growers are mowing ditches and small grasshoppers are starting to move into soybeans fields. Spraying the borders with Silencer can help keep the soybeans looking good.

Make sure you are using the right additives for your mix! If you don’t, you will not be very happy with your results. You could have poor performance or an unnecessary level of crop response.

Huron, SD


Wheat harvest is just around the corner. This is a good time to clean out your grain storage bins and spray them down with Tempo or Malathion for protection from insects. You may also want to put some Malathion dust in the grain while putting in bin depending on the condition of the grain and the length of time you plan to store it.

Kimball, SD


With the hot and dry weather in the area, volunteer corn may be harder to control in soybeans. Switching to crop oil rather than a NIS can help get better control by penetrating the leaf cuticle more effectively.

New Underwood, SD

Stay on top of unplanted fields and be sure to not let the grasses head out. The growth with some warm days under our belts has weeds growing at an alarming rate and some are going back out to see grasses covering the fields.

Roscoe, SD

Sunflowers right now are very susceptible to downy mildew with the current weather conditions. Keep scouting or use a preventative fungicide application.

Bryant Odlund


Watertown, SD

When spraying Laudis and not mixing it with glyphosate, make sure to switch from NIS to COC at 1 gallon per 100 and AMS at 8.5lbs per 100.

West Point, NE

We have been getting a lot of questions on Gray Leaf Spot up to the ear leaf. If you’re less than 10 days from full tassel I would spray ASAP and don’t add adjuvants. You will likely have no need for a second application.

Breckenridge, MN

For a little nitrogen and protein bump on your wheat, use ACLF’s NResponse at 2 gallons per acre with 2 gallons water. The timing works well with your head scab fungicide application at early flowering.

Fairmont, MN

If you are spraying soybeans right now the volunteer corn in the area is getting taller. Consider increasing your rates of corn killer to achieve control.

Evan Oberdieck

Volunteer corn is beginning to get on the large side for regular rates of corn killers. Try increasing the rate by 50% and it should do a nice job with this larger corn.

Hancock, MN

Edible beans are starting to flower. Now is the time to apply your first application of fungicide for white mold. Proline at 5.7oz. per acre or liquid Topsin (Incognito) at 30oz. per acre with NIS.

Janesville, MN

Remember to be out scouting your fields frequently. This recent weather has been favorable for another flush of weeds. While out scouting your fields for weeds, keep an eye out for any disease or insect pressure.

LeRoy, MN

The soybeans are at R1 now. They are just starting to flower. It’s a little too early for the optimum time for fungicide (R3 – First pod) but some growers have had success putting a 1/2 rate of fungicide on now while spraying Roundup and then coming back with the full rate at R3. It might be a beneficial application, since the environmental conditions this year really favor disease.

Marshall, MN

Soybean aphids have been spotted in a few fields around the edges where there is grass in the ditches. The forecast is predicted to be cooler the next couple days, and that may make the aphid population grow.

Aaron Spronk

The volunteer corn in many fields is getting quite large. Large enough to start giving trouble at standard use rates of many of the herbicides. If yours is also getting this large, an additional couple ounces per acre of your herbicide of choice should get you the control you are looking for.

Olivia, MN

We’re getting calls about timing on Warrant in corn and soybeans. You can apply up to 30 inch corn and R2 in soybeans. Anything after that you risk crop injury.

John Scheibel

Tall waterhemp has been particularly problematic in many soybean fields this year. To ensure great results, use the higher rate of Cadet at 0.9 ounces per acre with NIS at 1 qt. per 100 gallons.

Kory Johnson

With spraying season in full swing don’t forget to check any stored grain. Talking to growers the last few days, there have been some issues with insects.

Ulen, MN

If using Extreme remember that the glyphosate it contains is non-loaded 4lb product so you should be adding Durango or PowerMAX and 1pt per 100 of NIS.

Winthrop, MN

For waterhemp in our soybean acres that have started to flower our choices get limited. Cadet at .75 oz. or Cobra at 12 oz. along with 32 oz. of PowerMAX will do a fair job. Try to get weeds before they’re 6 inches high otherwise they can burn off and regrow from the bottom indicating that you used an insufficient rate of product.

Dean Christiansen

When you’re out there spraying your beans, it would be a good idea to jump out of your sprayer in parts of your fields and start checking for bugs. If you start seeing them now, you can likely add an insecticide to your herbicide application.

Great Falls, MT

To clean up weeds and grasses around grain bins and in the drive way, use a dose of Spike-80, but be careful to avoid using it anywhere near trees.

Sidney, MT

It’s a good idea to alternate to different fungicide groups when making multiple applications. Proline 480 SC fungicide is an option to control Ascochyta blight in crops such as lentils (4.3 oz. per acre) and chickpeas (5-5.7 oz. per acre).

Rockwell, IA

Just a reminder, when replanting corn field ponds to beans, check with your retailer on carry over issues that might affect your beans.

Sheldon, IA

Roundup applications on soybeans continue as fields dry up or as a new flush of weeds emerges. Adding MegaGro at 2 oz. per acre can help with the weed kill as well as help the soybean plant work through the Roundup. Cost is around $4.50 per are.

Buhl, ID

Numerous examples have been seen of the Spot Form of Net Blotch, also called SFNB, in Eastern Idaho and Montana. So far, damage estimates for production conditions have not been able to be determined. In other areas where the disease occurs, losses of 50-75% have been reported. Full rates of fungicides are recommended for control in susceptible varieties. The following fungicides have been used for control: Headline (6-9 fl. oz. per acres), Stratego (7 fl. oz. per acre), Vertisan (14-24 fl. oz. per acre),and Priaxor (4-8 fl. oz. per acre).

Hillsboro, ND

Now is the time to begin to scout for bugs. If temperatures stay moderate (high 70′s to 80′s) it will be prime for soybean aphids. Silencer at 3.84oz per acre will do a good job and will often give 2 to 3 weeks of residual protection.

Hurdsfield, ND

When working with glyphosate resistant kochia, there are three modes of action to work with. Group 2 which may not work if the kochia is ALS resistant as well. Group 6 which would be Basagran or Group 14 the PPO inhibitors. Because options are so limited it is important to keep control when weeds are small. You will see crop response when working with a Group 6 or 14 product. Using the correct surfactant is also really important depending on which product you choose.

Lisbon, ND

If you are still trying to spray your soybeans for the first pass, make sure you look closely. Some new flushes of weeds may have come in from the time you last scouted.

Brian Weight

When spraying biennial wormwood in your Roundup Ready Soybeans, be sure to use at least 32 oz. per acre of PowerMAX along with AMS and NIS.

Mohall, ND

Wheat midge are starting to show. When tank mixing Prosaro add it first and then Lorsban 4E. With Caramba use Lorsban Advance and add the Lorsban to the sprayer tank first. Spray late afternoon or early evening when the winds are light.

Pembina, ND

Soybean fields in the area are getting pretty full of weeds. When you finally get a chance to get out there and spray Roundup, strongly consider adding MegaGro or AC-97. These will help the beans overcome all the water stress that they are currently under.

Wilton, ND

Tissue sampling is important to determine nutrient deficiencies. Visual symptoms are helpful to decipher different types of deficiencies but they are not always conclusive. Once you have received the report back it is also imperative to know how to read the results.
