When weeds are present late, be cautious when spraying during flowering or reproduction. Read the label for pre-harvest intervals and timing on any product being applied. Sometimes it is better to wait for a pre-harvest desiccation of both the crop and weeds to avoid adding additional stress to the crop during reproduction.

-Seth Hanson

Disease management in corn has been a popular topic recently. I have gotten a lot of questions around timing, products, what hybrids to focus on, and many others. If you are only looking at spraying fungicide on select acres – do any corn on corn acres first as they will typically have the most pressure. After that I like to look to past farm history of disease, have you had certain fields with more historical pressure? If, however you are really looking at potential disease and plant health management, I believe there can be some hybrids that may respond to that management more than others, but most all hybrids can and will benefit from fungicide applications. There are a lot of products on the market with pros and cons to all of them, but the biggest difference you can make on your crop is to do something rather than nothing. If budget is a concern, I truly believe there is far more difference between an untreated acre and a second tier product than there is between a second tier product and a premium product.

-John Wiese

When spraying fungicide on corn and soybeans during these hot days, it is best to try to limit your hours of spraying to early in the morning or in the evening to avoid the high temperatures of the day. While most fungicides are labeled for high temperatures, better canopy penetration can be achieved by running 15 to 20 gallons per acre and making these applications in cooler temperatures.

-Glenn Herz

After Roundup applications, we still have a significant number of weed escapes in the sugar beet fields. Volunteer corn is relatively easy to control with clethodim earlier in the season. However, it’s important to consider the water consumption and the potential for corn rootworm infestation in these volunteer plants. As a standard practice, rotating beets after corn and spraying for these weeds should be implemented. Additionally, incorporating Warrant into the herbicide program earlier in the season could provide an extra layer of control against other difficult-to-kill weeds.

-Dusty Danos

The wrinkling on the edge of the corn leaf is often due to boron deficiency. It’s a good time to apply some boron before tassel.

-Eddie Gonzalez

Corn earworm eggs are showing up in some corn fields. Usually, they are on the upper, vertical leaves. When they get into the silk on the ear, it is much harder to get chemical to them, so the best time is before they get there. Brigade does a great job on these if applied at the correct timing.

-Tyson Goossen

Red crown rot in soybeans is an emerging disease in the area. Foliar symptoms of red crown rot are similar to those of SDS and phytophthora. The roots of soybeans with red crown rot will have characteristic red/tan-ish pustules. Unfortunately, there is no rescue treatment, but Saltro and Victrato are labeled seed treatments for Red Crown Rot. This field had lab-confirmed red crown rot 2 years ago, and now it is back, which means rotating away from soybeans for only 1 year is not good enough to reduce inoculant.

-Nicholas Paulsmeyer

It’s time for most farmers to start applying fungicide in the corn. I personally recommend using a drone at 3 gallons/acre and using either Veltyma or Adastrio that has multiple modes of action while also putting a fulvic acid in the tank, like Nutex EDA, to open the plant stomata and act as a transport mechanism for the fungicide.

-Teddy Van Gelder

With humidity levels up, the dew setting overnight, and increased temperatures, it is a great environment for disease to set in. It is still not too late to make a fungicide pass on your corn or soybeans. With fungicide though, remember it is a preventative, not a cure. Soybean timing is at first pod (R3) and corn is tassel to silking (VT- R1) for the best results.

-Alex Geraets

Crops in the area are looking really good. In order to protect your potential yields, consider adding a fungicide to both corn and soybean fields. Corn will be protected from diseases like southern rust and tar spot as well as helping with standability. Soybeans will get protection from frogeye leaf spot as well as increasing overall plant health for better yield. You can add an insecticide to this pass to improve your protection on any pests like rootworm beetles.

-Adam Sauer

According to NDSU researchers, winter survival rates for soybean aphids were high throughout eastern North Dakota and the Red River Valley, despite cold winter temperatures. We are not seeing aphid pressure currently but will need to keep monitoring for infestations.

-Jonah Sylvester

Not much has shown up in the area for diseases on corn or soybeans but many farmers are still inquiring about fungicides. Most are going to spray just based on potential since the crop looks so good. There are multiple agronomic benefits of a fungicide application beyond yield that can help mitigate stress and lead to a better crop.

-Mike Bates

While looking at soybeans in eastern Pope County, I am seeing a low number of aphids (10 to 40) on a few plants on untreated seed. On treated soybeans, numbers were zero on most and up to 10 on very few. While thresholds are low for now, keep checking in multiple places in fields because populations can rise quickly. Also consider an application of a plant health fungicide toward the end of July. The timing for aphid threshold and ideal fungicide timing may match up.

-Adam Gibson

Are you trying to get ahead and take care of those pesky woody trees along your fence lines and fields? Remedy is a great product that works very well on the woody type plants that many other herbicides struggle with. I personally like to make a tank mix of Duracor and Remedy, so you get an all-in-one tank mix for whatever comes in front of you while you are out trying to clean up some areas.

-Jesse Lundebrek

When you are spraying your fungicide, strongly consider adding Nutex EDA to your tank mix. Nutex EDA at 6-8 oz/acre helps transport the fungicide into the plant. Increasing intake into the plant enhances the plant’s response to the fungicide.

-Cody Dobberstein

There are a lot of rootworm beetles in the corn. Adding a cheap pyrethroid will work well to kill them, but using a product like Steward will give you much longer control and be safer to beneficial insects that could help you throughout the rest of the season.

-Grant Lunning

When applying your fungicides to corn and soybeans, be sure to add Nutex EDA to the mixture at 6 to 8 ounces per acre. Nutex EDA is a fulvic acid that really helps drive fungicides into the plant faster and more efficiently!

-Jeremy Jensen

We are already seeing corn rootworm beetles showing up in fields. If you’re out applying fungicide, now is a great time to add an insecticide to the tank mix. It’s a relatively inexpensive addition that can help reduce beetle pressure and protect pollination by limiting silk clipping where populations are high.

-Brandon Howard

Corn fungicide spraying is in full tilt. Be scouting for rootworm beetles or other bugs in the corn to add in a cheap insecticide while you’re going up with the plane.

-John Scheibel

If you’ve had white mold in your fields the last couple of years, now is about the time for a fungicide on soybeans. The best fungicide for this would be Zorina. It also is going to give you the longest residual. Another product that is effective is Topsin, but it doesn’t last nearly as long as Zorina. Spraying either of these while your soybeans are flowering is a great way to prevent white mold.

-Ross Hanson

When deciding to spray a fungicide on corn before the brown silk growth stage, make sure to use an NPE/APE-free adjuvant. By utilizing these adjuvants, you eliminate the risk of causing arrested ear development. Precisive is a great option to have in the tank with an early fungicide application.

-Matt Nowak

There have been a few reports of tar spot found in the area. Be sure to check your fields as soon as possible. There have also been a few fields with infestations of rootworm beetles and not all of them have been corn-on-corn.

-Kody Urwiler

Spraying fungicides on soybeans is a really easy way to boost plant health during pod fill. Best timing for this typically comes from an R3 application or spraying in the last week of July or the first week of August.

-Wyatt Mach

As we push into the month of July, I’m seeing lots of soybeans across the countryside starting to flower. I want to talk about a few different ways to treat Sclerotinia White Mold (SWM). A combination of Topsin and Domark works quite well, and depending on the rates it should only cost about $20/acre and provide good residual too. In double crop or late planted beans, if they haven’t flowered yet or are just starting to flower, use a 6 oz/acre rate of Cobra. Although it’s not a fungicide, it has been proven to be very effective at reducing SWM and it only costs about $4/acre. Finally, in the worst spots where the pressure has been the worst in the past, use Endura at 11 oz/acre. Please note this strategy is very costly (roughly $40/acre) but quite effective.

-Casey Doernemann

Corn is just starting to push toward reproductive stages. During these stages, the corn is the most susceptible to damage from fungal infections and pests. I would recommend spraying an early round of fungicide/insecticide before tasseling and another round later in the reproduction. This will give your corn the best chance of survival and maintain your high yield potential.

-Tristian Niles

We are seeing tassels begin to push through all over the place. Reproductive stages are high time for pests to destroy crops. As the silks begin to emerge and the corn begins to pollinate, make sure to have your insecticides and fungicides on before to ensure that your crop has maximum protection.

-Blake Beiber

Now would be a good time to treat your known problematic white mold spots in your soybeans with Endura. By just doing the known bad spots, it makes the overall cost more manageable and makes a better ROI across the field.

-Spencer Schultz

Are you looking to put a fungicide on your fields this year but don’t want to spend top dollar? Using 14 oz of Quilt XL and adding in 6 oz of FulFour and 7 oz of Vacciplant is a great option at an affordable price.

-Edwin Pluimer

Fungicide passes will be starting soon in the area. Adding FulFour to your fungicide will improve the plant’s ability to move the fungicide and nutrients through the plant.

-Brady Anderson

Soybean/Edible bean growth stages range from vegetative to R2. This is a perfect time to take tissue samples to see if Potassium, Zinc and Boron may be lacking. Diseases such as white mold, septoria, and blight need to be watched for as well.

-Matt Elder

Corn and soybeans are shifting into their reproductive stages. It can be a crucial time for nutrients and mitigating stress. The extended forecast shows a lot of heat, so make sure your crops have everything they need to maximize yield potential.

-Michael Duch

Corn is just starting to tassel in our area and now is a great time to get your fungicides on. With how hot we are getting during the day, I would recommend getting your fungicide sprayed in the early mornings or at night when it is cooler. Make sure the wind is calm while spraying so you can get good coverage.

-Brayden Hansen

Starting to see spider mites out in corn fields. They are very small, but you can use a magnifying glass to see them. They will produce webs, which are easier to spot. To control them, use a miticide like Zeal SC to take care of the adults, larvae, and eggs.

-Zach Hefty

I have started to see more Northern and Western corn rootworm beetles emerging and feeding on silks in conventional corn. Spraying bifenthrin will knock out these bugs before they eat more silks and lay eggs. Consider using an insecticide at planting or adding below ground traits next year.

-Lauralee Eaton

We have been receiving some reports of corn rootworm beetles showing up in the area. Be sure to scout fields to evaluate bug pressure and add an insecticide with your fungicide application if needed.

-Joe Schieffer

When spraying soybeans late, be careful to not hurt next year’s crop. Late season Flexstar can hurt next year’s corn crop since there is a 10-month plant back restriction. Cadet, Resource, Harmony SG, Classic, Fusilade and Clethodim all have a 60-day pre-harvest interval that you should be cognizant about when making a late season pass.

-Zach Polzin

As everyone should be finishing up on their last round of Liberty clean up passes, it is important to note that soybeans can only have two shots of a 43 oz rate of Liberty and a total of no more than 87 oz for the year.

-Dylan LeBrun

Corn fungicide season is upon us. With this hot, dry weather and winds coming from the south, it would be a good idea to plan on spraying corn. If you do decide to put out fungicide it would be a good idea to add insecticide and a fulvic acid product.

-Mark Swanson

There are some millet fields where I’ve been getting asked about chemical options. Amine is labeled, but before adding any other herbicides, talk with an agronomist to see if there are other options with the variety of millet seeded.

-Matthew Petersen

I have been seeing a lot of corn rootworm beetles in fields, and they are starting to clip the silks. I recommend spraying with a good insecticide, such as Steward or bifenthrin, to get rid of them and protect the corn.

-Travis Petty

Be sure to scout your fields for insects before spraying your fungicide. If harmful insects are present, consider adding an insecticide. I have found grasshoppers and aphids in most soybean fields in my area, and both can cause significant soybean damage.

-Emma McLnerney

While scouting for a fungicide pass, don’t get tunnel vision and forget to look for other symptomology that you can address while you are already going across the field. A tank mix partner like Silencer at 3.84 oz/acre is a cheap way to address grasshoppers and other insects while saving an additional trip across the field.

-Hayden Houdek

Continue to scout your corn and soybean fields for diseases and insects. The damp mornings we’ve been having are notorious for causing higher disease pressure. Applying fungicide along with a product like Nutex EDA will enhance the uptake and control these diseases.

-Lane Konrad

Keep an eye out for insect feeding in your corn and beans. Spider mites are moving into both crops, along with a few other insects. If insect pressure gets bad enough, we are still early enough in the growing season that it could warrant an insecticide application.

-Blayne Martinez

I’m starting to see increased pressure of spider mites in corn. I would recommend spraying if you have significant pressure in the lower canopy moving its way up to the ear leaf. Zeal SC is a great option for control.

-Conner Edelman

Most soybeans are in that R1 stage. If you have fields that have had white mold in the past, now is the time to treat for it. This year has been a good year for white mold growth. I would recommend spraying a full rate of Endura for the best protection. If you want to save some money, I would switch to Prabha at 13.2 oz/acre. This is a generic Endura and Proline premix. I also recommend running 6 oz/acre of a fulvic acid like Nutex EDA with each application. This will aid the plant in absorbing the fungicide.

-Spencer Frost

As we continue to maintain control over resistant weeds like kochia and waterhemp, it is important to monitor the effectiveness of your application. A waterhemp plant can produce over 1 million seeds that will cause problems in the upcoming growing seasons.

-Logan Scheel

While making fungicide passes in soybeans, take note of the insect pressure. There are multiple bug species being found in areas that may require the addition of an insecticide.

-Kyle Wiese

There have been questions regarding spraying Liberty and the appropriate weather for that application. Add temperature plus humidity together; we want that number to be at or close to 150.

-Jeremy Nedved

No crop report available

Be on the lookout for soybean aphids. I anticipate seeing them show up in larger numbers in the next few weeks.

-David Mack

We are seeing more acres of fungicide getting applied this week on corn and soybeans. With the high heat in the day, try to get your fungicide applied earlier in the morning when it is cooler out to help spray droplets stay wetter longer and reduce evaporation before it can penetrate the canopy.

-Preston Barragan
