Baltic, SD

Most beans are starting to transition into the R3 stage (begin pod), so now is a good time to foliar feed or apply a fungicide. The aphids are still at bay in most areas, but make sure you scout before you spray in case you need to add an insecticide as well.

Centerville, SD

We’ve definitely seen the outstanding results of using pre-emerge herbicides. Farmers have been big fans of products with multiple modes of action. In soybeans, Authority Assist and Fierce really kept fields clean. In corn, I’ve heard a lot of good feedback about TripleFlex, Surestart, and Verdict.

Freeman, SD

I’ve heard of a few soybean aphid cases around our area here, where the producers didn’t treat their soybean seed with insecticide at planting. The counts averaged around 15-20 aphids per plant. Keep in mind, that’s within the soybean aphid threshold at plant growth stage R2 of 10-20 aphids per plant. In this case, one option would be using Silencer, (generic Warrior), at 3.84 oz. per acre, or $2.25 per acre, which could give you up to 2-3 weeks residual.

When spraying your soybeans check for grasshoppers on the outside edges of the field. Silencer at 3.84 oz. per acre will offer good control.

Huron, SD


Continue to scout your soybeans fields for insects. We are seeing some grass hoppers in roadways and grass areas moving in to bean fields. Treating those areas with an insecticide may be a good idea. Silencer at 3.8 oz. per acre will give good control plus a few days residual.

Kimball, SD


There has been devastating hail in the area this summer. For acres that weren’t a complete loss, it is extremely important to put a fungicide application down as the crop begins recovery. Any lesions on stems or torn leaves give diseases a way into the plant. Make sure you protect the crop that is still in the field.

New Underwood, SD

There are some making some swaths on the wheat crop. After harvest, stay on top of grasses as they are still coming up.

Dane Oman



Roscoe, SD

Keep a close eye out for insects at this time of year. Grasshoppers are beginning to be a problem and others like soybean aphids can increase in population very quickly. Treatment with 3.84 ounces of Silencer is effective on most small bugs and aphids. Large grasshoppers are tougher and require at least 1 pint of Lorsban.

Watertown, SD

Many of the fields that were sprayed with Prowl or Treflan tankmixed with Sencor ( Glory) are very clean. This is definitely something to think about for next year. Many of the older products still work great and are priced right.

Jack Beutler

The soybeans in the Watertown area are approaching the (R-3) (R-4) stage. It would be a good time to apply Domark fungicide at a rate of 5oz. per acre to protect against white mold.

West Point, NE

We are seeing a few common rust lesions appear in corn fields across eastern Nebraska, although seldom economically a problem and reason by itself to apply a fungicide. A fungicide will help control the lesions.

For that tougher to control waterhemp in soybeans, add 0.5 oz per acre of Cadet with your PowerMax.

Fairmont, MN

We found our first significant amount of aphids that might approach threshold numbers.They were in an isolated spot of the field and only on a few plants but under the right circumstances they can double in a very short amount of time. If you do spray bugs don’t forget the fungicide it’s the best combo out there.

Mike Bates

We have started to find a few aphids out in fields. Nothing near threshold but be sure to keep scouting and have your insecticide ready to spray when needed.

Hancock, MN

Make sure you are following herbicide labels. There are many products that are not labeled for application at this time due to crop height or growth stage.

Janesville, MN

This is the time of the year to be out scouting your fields daily. Remember to be looking for other things besides insect pressure, such as disease pressure.

LeRoy, MN

I have been seeing a lot of fireflies out at night. That usually coincides with corn root worm beetle emergence. I don’t think we will have much pressure for CRW this year, but it is still a good idea to dig up your corn roots to see what’s going on down there.

Marshall, MN

Keep a close eye out for soybean aphids. There have been reports of low numbers in a few fields, but that can change quickly this time of year. If you have enough to treat, 3.84 ounces of Silencer is cheap and effective.

Olivia, MN

Silks are starting to emerge in many fields. This when adult rootworm beetles will begin to start showing up. When scouting for them, look at the silks, as this is where most of the feedings will occur. Applying Lorsban 4E at 1 to 2 pints per acre should work great against rootworm adults.

Kory Johnson

As we get close to the end of spraying soybeans it may be a good idea to put a fungicide in with your glyphosate and volunteer corn killer.

Ulen, MN

Aphids are showing up in low numbers. Silencer is a good product to use at 3.2-3.84 oz. per acre.

Winthrop, MN

When applying a fungicide to your crop, be cautious if you add in any foliar fertilizers. By the addition of a foliar fertilizer, the mixture can get pretty hot and do some damage especially if you are using a surfactant. The best bet is to leave out the surfactant unless you know for sure the mixture won’t get too hot for your crop.

Great Falls, MT

It’s time to start thinking about Malathion in the bins with your grain. Beetles, weevils and moths are no match for Malathion at 10 lb per 1000 bushel. Make sure you know who your end user is as some millers and buyers won’t approve.

Sidney, MT

Sharpen helps with both contact burndown as well as residual pre-emergence broadleaf control on weeds such as wild buckwheat, lambsquarters, kochia, and Russian thistle. Sharpen can be used in chickpeas, dry field peas, and wheat (including durum) but don’t forget to include the proper adjuvants: MSO at 1 pt/A and AMS at 12 to 15 lbs/100 gallons of water.

Rockwell, IA

We had our first call from a farmer that has 10 aphids per plant on his soybeans. Please be scouting your fields and looking for these pests. You might want to consider using an insecticide that has both knockdown and residual control such as Cobalt, Lorsban Advanced and Hero.

Sheldon, IA

We are starting to see some Goss’s wilt show up in corn fields. There is nothing you can do now but take note of which fields have it as you can choose more tolerant hybrids next time you have corn in that field.

Buhl, ID

Ear worm in sweetcorn can pose a threat to growers. Spray at 50% silk to reduce chances of the larvae getting into the ear. Pyrethroids at labeled rates will do the trick.

Hillsboro, ND

If the beans are looking good, a foliar feed product like AC97 at 32 oz. per acre is an excellent idea at R2 to R3 stage. It has a growth promoter plus nutrients the plant will take in, that can lead to a nice yield increase. This is the product Brian and Darren Hefty have had the best luck with on their farm, too.

Now is a good time to be looking for leaf disease in soybeans and checking for proper nodulation in soybeans. A fungicide may be good for bacterial blight. If you are not finding good nodules on the roots this may be a good time to review variety and your inoculation program. We are seeing root rot affect nodulation when it does not kill the bean.

Chad Weckerly

Even though we’ve had hot temperatures still be on the lookout for disease and other pests in soybeans. Aphids have yet to be seen, but keep a close eye. It is easier and cheaper to control a problem earlier than later.

Lisbon, ND

There have been reports of aphids starting to come in around the area. Make sure to be scouting your fields for these.

Mohall, ND

When planting cover crops, a good mix is 2-3 pounds of radish and 2-3 pounds turnips per acre. Also adding cereals or soybeans to the mix will help.

A lot of the soybean fields in the area are in the R1 to R3 stages of development. The R1 stage is when the plant begins forming flowers on the main stem and R3 is when the plant is beginning to set pods. Anytime in this window would be a good time to spray a fungicide on your beans. Products like Priaxor or Stratego YLD have shown great returns on investment the past few years. We have consistently seen 3-4 bushel gains and upwards of 10 bushels in certain incidences. When spraying fungicide at this time I would use high water volumes (15-20 gpa) and use a non-ionic surfactant at 1 quart/100 gallons of water. It would also be wise to scout for soybean aphids at this time. If you have populations that are on the rise, I would consider throwing in an insecticide.

Wilton, ND

The soybeans are looking healthy with all the recent rains we have had. Continue to scout for aphids and consider a fungicide at this stage to help with white mold control and some plant health benefits. There are many options so contact an agronomist to visit about your options.

Jamie Schurhamer

With wetter conditions and cooler temperatures this summer, we are seeing some disease in crops such as bacteria blight in soybeans. It can easily be confused with rust so pay close attention to what it looks like on the leaves.

Bertrand, MO

Many farmers are beginning to apply a fungicide on their soybeans, a product like Stratego YLD at 3 oz. per acre might be a good choice.

It might be easy to just sit back and watch the crops finish out, but this is the time to really hunker down and get some planning done. A detailed plan of attack can be instrumental in a successful harvest season. It will also help you remember some of the seemingly less important things that can creep up and cause a genuine problem right when you don’t have the time. Dutiful preparation now leads to success later.

Quincy---Leonard-Lundgren-Ty-Whitaker-Sam-Krautscheid-Ken-WiserNeed to be watching for lygus in our beans, if you find more than 5 per sweep consider Dimethoate. If beans are in bloom adding a foliar nutrient should increase maturity and yield.
