In the east, crops look amazing, considering the tough start we had, and timely rains have helped get them in a great spot to finish. Currently, we’re applying some fungicide on corn and R3 treatment on soybeans.

The biggest question lately is, why is waterhemp popping up in my soybeans? Even after the best spray programs, we’re still seeing some here and there. Well, residuals like Warrant and Dual are starting to run out. The thing that we must understand is that waterhemp can germinate and survive with almost no sunlight, so we’re going to have some come up.

Over the last part of July and the start of August, we have been applying fungicides like Endura, Delaro, and Miravis Neo to preserve yield potential in soybean fields that exhibit mold invasion. It is important to continue to scout for mold development through the season, since the fungicide application is effective for only a couple of weeks. Additional fungicide application may be warranted in some fields.

Most of the timely planted corn is exhibiting brown silk, and aerial application of fungicide is being made to enhance yields. Incorporating Masterlock with the fungicide is recommended to enhance the effectiveness of the application.

Late summer seeding of alfalfa can be a viable option for growers where small grains or other early harvested crops are now off. Complete your seedings as early as possible in August to allow for establishment of the stand ahead of frost.

In addition, you should plan now for fall application of fertilizer so that you can save money on materials and prepare the soil for next spring’s early planted crops. Fertilizer products are generally priced favorably at this time of year and applications can be made as harvest is completed. Contact your agronomist to discuss favorable financing options for these applications through Verity as well.

With pollination in full swing, there are a couple of things to keep in mind with your corn and soybean crops. First, make sure you know what stage your crops are in. Second, be able to identify yield-robbing disease and insect pressures. Apply fungicide and add insecticides where needed. Contact a Landmark agronomist to help identify any issues so we can help maximize your yields. I’m providing a few slides to help with distinguishing growth stages of crops and as well as the identification of insects that you’ll see this time of year and the damage they cause.

We made it to the finishing stretch—corn and soybeans are in their reproductive development stages and look exceptional, for the most part. This doesn’t mean it’s time to take a vacation until harvest; there are still risks in the fields we need to keep an eye on. In corn, a few things we have started to see in fields are disease and insect feeding.

Gray leaf spot and tar spot are a couple of diseases we’ve seen popping up these past few weeks, and both can cause 50% or greater yield loss with severe infection. We still have time to set up an aerial fungicide application where we can apply a fungicide to help that corn reach its full yield potential. Another important thing to keep an eye on is insect silk feeding from adult corn root worm beetles and Japanese beetles. If corn is still pollinating and silks are full of insects, or silks are clipped a half an inch or less from the ear, contact your local Landmark agronomist to access what steps can be taken.

On the soybean side, insects continue to be at the top of our radar. We expect soybean aphid numbers to continue to grow. For that reason, we recommend that when a soybean field is treated with herbicide or fungicide, an insecticide should also be added for residual protection. In addition, we expect to start seeing soybean disease showing up in fields. When the fields canopy, it creates a microenvironment suitable for disease. Fortunately, Landmark has great options for fungicide treatment to protect your soybean health.

As always, have a safe week and contact your local Landmark agronomist with any inquiries.

Corn is beginning to tassel across the state and planes are beginning to fly on fungicide applications. Now is the optimal timing for R3 fungicide applications on soybeans as well as VT applications on corn. Tar spot in corn has been frequent topic since it first hit hard in 2018. The graphic below shows confirmed tar spot incidence by county the last five years. We can see that tar spot has consistently spread to most southern Wisconsin counties each year. Scouting fields has shown us that infection may start in the upper leaves because of how easily the spores travel by wind. At this stage in the corn plant, top leaves are the most crucial to the photosynthesis process leading to grain fill. These top leaves can be protected by an aerial fungicide application. When selecting a fungicide from the many options available, it’s important to choose one with a broad spectrum control, multiple modes of action, and solid residual.

Talk with your local Landmark agronomist if you have questions about whether fungicide will be a good fit.

The crops in the far eastern part of the state are really starting to take off and are looking good. We had a stretch of weather in mid-June through early July when we were short on moisture; since then, the east has caught some rain that really pushed the crops along.

A large portion of our corn is at VT or almost there. Fungicides have been a hot topic with growers; there is a high potential for yield on this year’s corn crop and the weather has been conducive to disease issues. Commodity prices are still suppressed, but protecting or improving yield potential is an easy way to overcome lower prices. Lower crop prices have driven some growers to purchase more cost-effective types of seed, but lower-traited corn appears to have increased the incidence of disease.

While walking some corn fields for disease, I found fields that had a lower trait package of corn. While walking, I also found severe silk clipping, goose-necking, and extreme ear tissue feeding on this corn. These three things introduce plant health issues as well as fall standability and harvesting issues. The images below illustrate the aforementioned health issues as well as the culprit: western corn rootworm and northern corn rootworm beetles. These fields will need to be sprayed by air with both an insecticide and fungicide to preserve what crop is left. I know that prices are low and a lower-traited corn may be cheaper, but talk to your agronomist before making a decisions based on price, as it’s not always the best agronomic choice.

Our Stine dealership has been a great thing this year when it comes to soybean weed control. The Stine E3 beans have given our agronomists multiple tools for controlling weeds, especially waterhemp, this year. Having the ability to use Enlist, Liberty, and RoundUp on these beans has allowed many of our fields to be extremely clean while not having the application constraints that the Xtend beans have. Moreover, the Stine beans look extremely good, with a very bushy bean that is dark green in color. If you didn’t use these beans this year, I recommend talking to your agronomist about how the Stine beans and E3 herbicide package can help your bottom line in the upcoming growing season.

Our third crop hay is moving right along to cutting maturity. The alfalfa caught a couple of timely rains and it looks like it may outyield our second crop. Fungicide applications on hay are becoming popular on hay in our area again. We did a few fungicide trials for growers for this crop and they can already see the increased leaf retention all the way down the plant. This increased leaf retention will increase quality as well as tonnage per acre. If you’re not using fungicide on your hay, contact your local Landmark agronomist about the benefits of it.

Lastly, wheat yields seem to be spread across the board with some in the 80s and 90s, with some in the 50s. Straw yields seem to be lower than normal, with most growers getting as low as they can when cutting to increase the yield.

From the Field 7-14-2020

The first week of July has brought us some strong storms with some well-needed rain, and with these storms I have seen some lodged corn. In most cases the corn is trying to straighten back up, but I have come across a few plants that have green snapped. It’s getting close to the start of applying aerial corn fungicides, and I’m seeing fields with a wide range of crop development.

A few fields started showing tassels last week and may not finish for another ten days. With the uneven tassel and silk emergence, I would recommend monitoring rootworm beetle activity. The rootworm beetle can be very mobile, and when it moves to these late pollinating plants, it can cause silk clipping. I am seeing a few Japanese beetles in the soybean fields, but nothing close to threshold levels. However, the potato leafhopper pressure in alfalfa is as bad I have seen in years. The leafhopper pierces the leaf and sucks the sap from the plant, causing it to turn yellow. This is referred to as hopperburn. With the right weather conditions we can see several generations of this pest. I am recommending to spray once regrowth has started.

With heat, heat, and more heat—and a good drink of water—corn was able to really kick it into gear. After the slow start in the spring, the summer heat wave gave us an abundance of GDU’S and now we are ahead of the norm. As I drive around the countryside, I see a lot of great corn growing. Each field holds the potential for high yield, so let’s protect those bushels.


From the Field 7-8-2020

Many of the corn fields are nearing or at VT. I think we, potentially, are on our way to another very good crop. Pre-tassel or early tassel is prime time to apply fungicides to help protect the crop from diseases and help with stress mitigation. In the next week or two, it will be time to contact your Landmark agronomist to get your fungicide application scheduled.

Many of the bean fields that were still looking rough a few weeks ago have really turned around and look good. Still a lot of spraying going on as the pre-emerge herbicides are breaking. Most beans are at that R1 or R2 stage, nearing R3. R3 is the time we usually see the biggest responses to fungicides and micro packages.  I have not found any aphids, yet but have reports of a few very low populations being found. The bigger concern going forward with the heat we’ve been enduring, is the concern about spider mite infestations. Keep an eye on field edges for yellowing or wilting plants.

Second cutting alfalfa is pretty much done. It’s been a few years since we’ve seen potato leafhopper numbers as high as they are right now. Populations grew fast, with some hopper burn showing in some fields that didn’t get treated after first cutting. Again, get a hold of your Landmark agronomist and have them sweep your fields.

Wheat fields are nearing maturity and I expect to see some wheat harvest starting here within a week.

Thanks, and have a safe summer.
