I’ve been seeing a lot of aphids and thrips in alfalfa fields. You can take care of these bugs for around $5 with 1 pint of dimethoate.

Tyson Goossen

If you are planning on planting conventional alfalfa this fall and are looking into a pre-emerge, use Eptam at 2 quarts per acre.

Eddie Gonzalez

Is it possible that insects affected my corn pollination? Yes. Corn rootworm adult beetles “clip” corn silks. The clipping then won’t allow silk to carry pollen to the awaiting kernel, resulting in reduced kernels per ear. Now is the time to reduce the number of adult corn rootworm (CRW) beetles that are laying eggs for the 2021 crop. Other damaging pests to scout for are Japanese beetle and corn aphids.

                • Mustang Max at 5 oz per acre OR Cobalt Advanced at 26 oz per acre
                  Tank mix Smart Trio at 1 qt per acre and 1 qt of AC-97 for broad-spectrum nutrition

How can I avoid July/August weed spray in soybeans? The answer is by utilizing pre-plant applications and residual post applications. Avoid late-season weed escapes with pre-plant foundation soybean herbicides. Late season weed escapes are difficult to control due to canopy and size. They are also expensive due to higher rates, with risks of reducing yield.

Todd Robeoltman

It is not too late to be spraying the edges of your fields! Field edges usually have more weed and grass pressure, and in a lot of cases, are easily sprayable and inexpensive. Same goes for your ditches. Keeping field edges and ditches clean will not only look much better but will also help the following year in keeping your fields clean!

Haley Wagenaar

Fungicides can increase plant health which can benefit you come harvest time. Fungicides will obviously take care of diseases, but if your plants are already weak, a fungicide application can help prevent the plant from breaking over and laying on the ground.

Jordan Loewen

After a hailstorm it is a good idea to wait a few days to apply a fungicide especially after an event pictured below. It will help with harvestability.

Travis Parsons

Sudden death syndrome can be a tough yield robber in soybeans. One thing to consider is using a soybean variety that has good tolerance to SDS. You could also consider using a seed treatment like Ilevo or Saltro to control this disease, as it starts from an infection in the roots of the soybean plant. Later in the season, you can use Fortix fungicide for suppression of SDS at R1 for best results.

Sam Geistfeld

We are starting to see a few more aphids in the area. With the cooler conditions, make sure you are scouting often as the aphids may be rapidly reproducing under these conditions. Generic Lorsban can be used for a little over $4 per acre, or generic Warrior for under $2 per acre. Keep in mind, residual on insecticide is drastically reduced after a rainfall event. With the cooler conditions and even a heavy rain event in the last 2 weeks, we are still seeing spider mites. Be sure you are actively scouting for these, as they can cause economic damage in the R4-R5 growth stage. For spider mites, generic Lorsban or bifenthrin will give you control, 2nd generation pyrethroids such as Warrior will not control them.

Nathan Rolling

Wheat is being harvested fairly early in our area when compared to the past couple of years. If you figure October 1st as the potential first frost date, that gives us roughly 60 days of growing season left, giving weeds ample time to germinate, and put on seed. There are a couple of options to consider this fall. A cover crop can be extremely beneficial, and there are many options available. We have also seen nice results doing fall burndown herbicide with added residual herbicide. Just be sure to pay attention to crop rotation when selecting products.

Aaron Giese

I am hearing about several farmers picking up neonicotinoid insecticides and having it applied by ground or air for soybean aphids. So far none of the farmers I talked to were warned by their salesman about the danger of spraying this around beehives. Bees will take this chemical back to their hives and it will kill other bees. Please do not use these products post-emerge! This class of insecticide is very good systemically so it should be only used as a seed treatment. I recommend you use Sefina or Transform within 1-2 miles of beehives. On every other acre, I recommend using 16 oz of Lorsban. Lorsban will give you nearly 100% kill of insects in that field at the time of spraying and not have the residual that will hurt the other beneficial insects that may fly through that field in the days after.

Adam Gibson

Many soybean fields in the area have a large number of grasshoppers, especially in field borders. Some good options to control these grasshoppers would be products like chlorpyrifos or Warrior.

Todd Brinkman

We haven’t seen a lot of bugs in soybeans, but there are some fields that do have some aphids. You’ll need to keep an eye on them until about R6, aphids won’t normally affect soybean yields after that point.

Grant Lunning

In the Canby, Boyd, and Dawson area we are seeing high enough pressure from spider mites to justify an application of 1 pint of Lorsban, or a generic form, to gain control of this generation.

Mike Homandberg

If you are looking at your soybean crop and thinking it might be too late to spray on a fungicide, it probably isn’t. Soybean fungicides can still be beneficial up to the R5 growth stage.

Jeff Gladis

If you are having trouble with newly established alfalfa, try adding RzyUp SmartGrass along with your insecticide and fungicide pass. This will help it grow faster, add tonnage, and improve overall quality. Additionally, you can apply it to your lawn to keep it more lush and green.

Jeremy Jensen

Not everyone is experiencing full thresholds of all one insect alone. Some may have aphids, some may have spider mites, and some may have other insect issues that I haven’t seen myself. But if you group them together equaling an economic threshold, that becomes a sprayable level. In my area we are experiencing spider mite issues. Spider mites are typically only killed with an organophosphate type chemistry, which would consist of Lorsban or Cobalt. Spider mites lay eggs at a rapid pace and even after an application of Lorsban the eggs would hatch days later, and the issue wouldn’t go away. The key with spider mites is to catch it early and get it sprayed quickly. You will first see them start along the edges of fields near grassy areas and often when it is hot and dry.

Dave Timmerman

There are more and more bugs showing up. Keep scouting and treat if necessary. Be sure to check the PHI on any product you may use.

John Scheibel

We are seeing a fair amount of rootworms in corn fields in our area. Make sure you are out scouting your fields for the next seasons, especially where you are planning corn on corn.

Brandon Howard

Soybean aphids are in the region. They are active but not everywhere, make sure to scout near the newest leaves of the soybean plant as populations are changing weekly. Grasshoppers continue to be a problem and are moving into soybeans as ryegrass and spring wheat are matured and being cut.

Scott Younggren

If you are doing any spraying with herbicides or insecticides this late in the season, make sure to check your pre-harvest intervals before spraying. Some products have over 30 days from spraying to harvest.

Dean Christiansen

Aphid numbers continue to remain low while it seems spider mite, grasshopper, and green cloverworm populations are on the rise. All three of these can do some serious damage in your soybean fields. The best way to control all of these species is with a chlorpyrifos product, which is a generic Lorsban. We have seen great control at one pint per acre.

Now is the time to get your fungicide and insecticides on soybeans if you haven’t done so already. Soybeans are pushing very hard with many at R4.

Kody Urwiler

It is important to be scouting your fields once a week for harmful insects. Bugs can hurt yields and need to be addressed when an economic threshold is met. Adding an insecticide with a planned fungicide application can greatly assist in plant health.

Chris Pranger

I’ve had a lot of questions about whether or not a fungicide application will still pay. The answer is not an easy yes or no. Every grower may have a different decision based on harvest decisions and hybrids that were selected. Work with your seed agronomist to determine which hybrids have the greatest risk to disease pressure.

Michael Wiese

We have been seeing southern rust confirmed in several counties around us. Make sure to be out scouting your fields, keeping in mind how early it has shown up this year. If you decide to pull the trigger on spraying a fungicide, make sure you choose a product that will cure and prevent southern rust.

Jared Steffensmeier

We are seeing southern rust creep in the area. There is still plenty of growing season left and it will be critical to treat for this disease as it can cause significant yield loss and hinder the corn’s harvestability. Multiple mode of action fungicides that contain a triazole are ideal for treatment.

Josh Dexter

A lot of the soybeans and edible beans are setting pods. It’s perfect timing to apply 1 – 3 gals of Sure-K fertilizer foliar to these beans for a cost of $5 – $16.

Now is a great time of year to get out and double-check your fertility program on corn by taking a tissue test to see what you missed this year. Also, since a lot of wheat has been harvested you can get a jump start on soil testing right away on your wheat stubble.

Ryan Brick

We are seeing rootworm beetles clipping silks. I recommend spraying these with something like 3.2 oz of Baythroid. Not only will this help with pollination, but it will also help keep numbers down for next year.

Jay Barnett

Be sure to be scouting your soybean fields for insects and mites. Aphid numbers are increasing in certain areas and we are also seeing some two spotted spider mites. Spider mites typically become an issue when we have hot and dry conditions. Not all insecticides are effective on spider mites. For example, applying 2nd generation pyrethroid insecticides (such as Warrior) can cause spider mite pressure to increase in the field. Use bifenthrin or Lorsban instead.

Joe Schieffer

I have seen lots of frogeye leaf spot in soybeans lately. I recommend using a product with two modes of action like Priaxor at 4 oz.

Koty Short

I have been seeing a good amount of rootworm beetles in corn clipping silk. Once you start to see them, it would be wise to consider spraying ASAP before they lay their eggs and go dormant until the next corn crop. Thresholds vary based on how stressed a crop is for the year, but when you’re seeing a couple or more per plant I wouldn’t question spraying it. The attached picture is an adult northern corn rootworm beetle.

Ty Iverson

We are beginning to see a little more bug pressure in the area. Continue scouting your fields as we are looking at a bumper crop this year. Spraying an insecticide will cost you roughly $2 per acre.

Lane Konrad

Consider adding copper sulfate to your water tanks to prevent algae from growing.

Eric Butz

Make sure when doing wheat stubble burndown that you don’t mix RT3 with amine. If you are using RT3, make sure to use LV6, which will eliminate any tank mixing problems.

Kyle Hawkinson

We are not currently seeing much for bug or disease pressure yet in our area. Keep scouting your fields, it is much easier to catch a problem early and eliminate it than to lose yield because you were too late.

Jarid Bechen

Be sure to continue scouting for insects in soybeans. In many cases it doesn’t take high numbers of any insect to justify spraying.

Kyle Wiese

If you plan to put a cover crop in after your wheat harvest, be careful with what you use for a burndown. Use something that will take out weeds but won’t prevent your cover crop from growing. Roundup or paraquat should do a good job and not leave a residual.

Mike Erickson

Make sure you are still going out and scouting your soybean fields, as some late season insects can start to show up.

Tyson Serr

We are seeing a lot of rootworm activity around the area. Rotation is probably the best thing to take care of them, followed by heavy rates of bifentherin if you’re going to plant corn again.

Jeremy Nedved

I have been seeing bean leaf beetles and a few aphids. Any pyrethroid like Warrior, or a generic, will do a good job at 3.84 oz.

Beau Wensing

Remember that if you are looking for plant health fungicides for your soybeans, you can use Delaro up until R4.

Jack Beutler

We are starting to see some insect pressure in our area lately. Be sure to scout your fields often to make sure this isn’t an issue on your farm.
