Ag PhD’s Crop Scouting Reports



Check Below for the Daily Crop Scouting Report for Your Area.

Crop Reports are updated daily Monday through Friday, May 1 – July 15.  From July 15 – August 31, the report will run weekly.

South Dakota

Aberdeen, SD

We are starting to see some bean leaf beetles and cutworms show up in soybeans. Silencer (generic pyrethroid) at 3.5oz. per acre will take care of most bug problems.

Tanner Johnson

If you want to give your plants a little boost and promote greener growth try using MegaGro at a rate of 2 oz. per acre tank mixed with Roundup. Area farmers have been saying it also seems to give the Roundup more killing power.

Baltic, SD

Since rotation restrictions have brought an end to using Flexstar to control waterhemp, there are a couple of good alternatives: Cobra at 12.5 oz. an acre or Ultra Blazer at 16 oz. an acre. Both will do a fine job at suppressing late flushes of waterhemp.

Mike Drey

I am starting to see a few grasshoppers show up in some bean fields. Most of the feeding I see going on doesn’t require an insecticide treatment but if the damage exceeds 40% defoliation, a treatment is warranted. There are several insecticides available and all of them do a good job at controlling grasshoppers.

Centerville, SD

With how damp things have been in our area, spraying a fungicide is definitely a good idea. Products like Equation (at 3 ounces per acre) or Evito (at 1 ounce per acre) end up costing just over $4.00 an acre. That’s not too big of an investment, especially when it offers a chance of increased yield and disease prevention.

Kelly Gates

Seeing stalk borers on field edges of biotech and conventional corn fields. Border treatments of insecticide have been effective. Also seeing some European corn borers out in conventional corn fields. Keep a close watch where non BT corn was planted as this corn does not have protection from European corn borer. Spraying an insecticide can be effective if you catch corn borers just as they hatch.

Freeman, SD

Some hail storms have passed through the area recently damaging crops, mostly beans. It will be very beneficial to tank mix a fungicide with your next Roundup pass. Fortix at 5oz. an acre will be a great option.

Gettysburg, SD

If you are around sensitive crops when spraying and want something to help with drift, add Gateway at 3 pints per 100 gallons of water.

Huron, SD


Hail damaged corn can benefit from a timely application of a fungicide, full rates with high pressures and ample gallons per acre are critical as full coverage is important.

Alan Williams

If you are still looking for a product to add to Roundup you can use Cadet at .5 to .9 oz. per acre plus 1 quart of NIS per 100 gals of water. This will help with lambsquarters and waterhemp.

Kimball, SD


With the recent bump in commodity prices, foliar products that have been proven to increase yields are now economical. AC-97 is a blend of plant growth regulators and fertilizer. It has shown to increase soybean yields over the last few years.

New Underwood, SD

With all the rain in the area make sure you put out a fungicide on your corn. Let the corn get to V6 – V7 so there are more leaves on the corn plant that you can protect. Priaxor at 4 oz. an acre should do the trick.

Roscoe, SD

Kochia escapes are tough to bring down in soybeans. A full rate of Cobra or Cadet are your best bets. Next year, use a pre-emerge herbicide program of Prowl + Authority MTZ to stop kochia plants before they emerge.

Bryant Odlund





Watertown, SD

If you are looking for something to try on your soybeans for a yield booster try AC97 at 1qt. per acre. Apply at the R2 to R3 stage when you’re spraying a fungicide.

Jack Beutler

If you have 12 inch tall volunteer corn in your soybeans you may want to increase your rate of generic clethodim to 6 oz. per acre. Don’t forget to add 1 qt of NIS/ 100 gallons water to improve the consistency of performance.

West Point, NE

With increased rates of Roundup being used to kill weeds since Flexstar can no longer be in the plan, we are using MegaGro to keep the beans growing during a very important time in the plant’s life.

Breckenridge, MN

It is becoming late in the season to use Flexstar due to the 10 month rotation restriction to corn and 18 month restriction to sugar beets. Consider using .5 oz. per acre of Cadet mixed with your Roundup and 1qt/100 NIS to control small broadleaf weeds in the soybeans.

Fairmont, MN

Triplet lawn herbicide is working very well on the evil white clover and other broadleaves. Spray now and re-apply this fall to hit the weeds hard and get your lawn back.

Steve Draper

I saw some aphids in a field today. They were not close to threshold levels, but it is definitely something to keep your eye out for in the near future. They can easily and cheaply be controlled with an insecticide like Silencer at 3.84 ounces per acre.

Hancock, MN

Many beet fields have canopied in the last few days. With great yield potential and a very dense canopy, growers just started spraying to protect against Cercospora leaf spot with their first pass of fungicide. Most growers are using Proline this pass as their triazole.

Janesville, MN

We ended June with 547.5 GDU’s. That is 9.5 above the 30 year average.

LeRoy, MN

I have had a report on bacterial blight in soybeans. This will look a lot like brown spot but will have yellow halos around the spot. This also is towards the top of the canopy. It occurs in cool, wet conditions and some dry days and heat will clear it right up.

Marshall, MN

There have been a few farmers talking about armyworms in their wheat this year, and there have also been some signs of early insect damage to soybean fields. Keep your eye out for any more signs of possible pests in your crops.

Aaron Spronk

Iron deficiency chlorosis, also known as IDC, is showing up in large areas of the soybean fields around the Marshall area. Although there is no overnight fix for IDC, one thing you may want to consider to help the soybeans recover faster from IDC is to foliar apply a product called Soygreen. Soygreen is a chelated iron product that get the correct form of iron into the plant helping it recover from the IDC effects.

Dave Timmerman

Soybean spraying is now almost done. It’s time to evaluate the program for the year and figure out what worked and what could have been better. Do this now while it is still fresh in your mind. Take some notes for any adjustments that could be made and talk to your agronomist about what you could do to make it better or more cost effective

Olivia, MN

Now would be a good time to prepare for spraying a fungicide on your corn. You would get plant health benefits and have protection in place in case of a weather event. Ideally applications should be timed after full tassel to reduce issues with pollination and potential stress to the crop.

Ulen, MN

When scouting your bean fields for a 2nd pass of glyphosate and aphid pressure consider tank mixing in a fungicide as many fields are approaching the correct timing for that application (R1-R2). Stratego YLD and Priaxor along with Fortix are all good options.

Winthrop, MN

If you are spraying your soybeans in the next week, it would be a good time to add in a foliar micro nutrient package. TJ MicroMix has shown a yield increase in the past at 1 to 1.5 qts. per acre.

Dean Christiansen

Yellow spots have started showing up pretty early in some bean fields. Unfortunately there isn’t much that will help them at this point. We have seen products like Soygreen and GreenBean applied and it usually helps the beans turn a little greener but we haven’t seen much yield advantage to foliar feeding an Iron product this late. The best option is to know where your high pH spots are in your field and use Soygreen or GreenBean in furrow.

Great Falls, MT

Spotted knapweed is coming on strong. 24 ounces of GrazonNext with an appropriate amount of the adjuvant, Speed, will do the trick with a long residual.

Sidney, MT

Reports from county extension agents from northeast MT are indicating some high levels of wheat midge counts. If the crop is in the just heading to 3/4 flowering and you find one midge per 6 heads it may warrant an insecticide. Mustang Maxx and Lorsban are a couple options.

Rockwell, IA

Northern corn leaf blight has shown up in some corn fields. Scout your fields for disease and consider applying fungicide this year as the wet weather is making the corn plants susceptible to fungal diseases. Tolerance varies greatly by hybrid so scout all your fields.

Sheldon, IA

Liberty Link soybeans have been looking very good so far. The key to spraying Liberty is you want sun, heat, and most of all coverage. 20 gallons per acre will provide very nice coverage with 29 oz. of Liberty. The beans will stay green all year long.

Buhl, ID

Spider mites are starting to show up in corn fields in Northern Utah. Zeal at 2 to 3 oz. will provide long lasting control.

Hillsboro, ND

Kochia can be a yield killer. If you are experiencing resistance to glyphosate, we’ve had good luck adding Flexstar to burn down the kochia. The beans seem to come back faster and choke out most of the kochia. If you have a small area that comes back heavy, tillage may be your only option, but keeping the plants from producing seed is very important.

Hurdsfield, ND

When scouting soybeans keep uniformity in mind. Disease and insect damage progress over time. If an entire field is uniformly affected at the same time, it might not be a disease or insect issue.

Lisbon, ND

I have seen some fields that have been sprayed with Liberty and the weeds were canopied over other weeds. The weeds under were not hit with the Liberty. Make sure to be careful of this and make sure you are getting excellent coverage.

Mohall, ND

If you used a post-plant – pre-emerge herbicide and it’s working great in your soybeans, you should still use at least 24 oz. of Roundup in-crop. If you didn’t use the pre and kochia is an issue, use 32 oz. of Roundup and up your rate of AMS. Be mindful that kochia is becoming Roundup resistant in other areas and could be spreading here as well.

Pembina, ND

A lot of the dry bean fields in the area are starting to develop a few flowers on them. We are probably only 7-10 days away from beginning to spray for white mold. Products like Endura and Topsin have shown good control of white mold in the past few years.

Wilton, ND

Now is the perfect time to begin checking your soybean fields for nodulation. Certain factors can lead to poor nodulation such as higher levels of nitrogen in the soil and the presence of fungi that cause root diseases or even just IDC. A nitrogen rescue treatment might be considered if you are having nodulation issues in your soybean crop.

Bertrand, MO

Most of the corn around here is at full tassel. It’s the perfect time to apply a fungicide like Stratego YLD at the 2.5 – 4.5 oz. per acre rate. To enhance disease control, use the lowest recommended rate of a NIS adjuvant.

Farmington, WA

Stripe rust infection in spring wheat seems to be stable and not spreading too fast with the dry, warm conditions. Susceptible varieties should still be monitored closely for active rust. If it’s








Quincy, WA

We had some pretty high aphid numbers in the alfalfa. Now that second cutting is underway make sure you are checking adjoining fields for insect migration.
