I was just in an alfalfa field with a bunch of alfalfa weevil larvae. The larvae will suppress new growth, causing fewer tons with the next cutting. Products like Silencer, Declare, Warrior, Lorsban or Baythroid will knock them out. Scout your alfalfa fields.

With the warm weather we have had, these soybeans will pop through fast. Make sure you check your fields for emergence before spraying pre-emerge herbicides like Valor.
Chris Robinson
A number of questions are coming in regarding no-till soybean fields that have not been planted yet. The fields are quite weedy, and some of the weeds are large. The general consensus is that the fields should be sprayed first. After spraying, wait two days before planting. Use a higher rate of glyphosate with a pre-emerge herbicide that will address your weed spectrum.

Make sure you are out scouting your alfalfa fields! We have been seeing high populations of weevil larvae around the area. Spraying an insecticide like Silencer at 3.2 oz./A will give you great control before new growth appears.

Things have dried out significantly in western South Dakota due to the warm, windy weather over the past week. Winter wheat development has slowed as a result. A few growers are still planting spring wheat, hoping to get it in before this weekend’s expected rains.
Dane Oman
Roscoe, SD

SDSU has confirmed Roundup resistant kochia in the area. There are no good options to control it post-emerge in soybeans. Use pre-emerge herbicides like the Authority products to wipe most of them out before they can hurt your crop.
Bryant Odlund
Watertown, SD

Pastures are getting dirty. If you see leafy spurge, make sure to use some Tordon at a 1/2 to 1 quart per acre on patches.
Jack Beutler
Looking for a great pre-emerge herbicide in your beans? Use Valor at rate of 2 oz./acre. Valor will do a great job on your small-seeded broadleaves.

Be on the lookout for leafhoppers. We have been getting many reports about them in wheat fields. A shot of insecticide will take care of them with your first pass.

Time is running out to get your soybean pre-emerge herbicide applied before the expected poor weather conditions arrive for this weekend. Remember that the seed must not be poking through or you will surely kill the plants.

There are some sugar beet fields in the area that are being replanted due to crusting. Make sure you are doing stand counts because there may be more fields that need to be replanted. Less than 150 beet plants in 100 feet of row is getting questionable. Nathan DuHoux
It’s a good time to spray an extra residual herbicide on end rows, along waterways, and in those weedy crop lines. Outlook can be sprayed pre-emerge and post-emerge in the following crop situations:
1. Corn up to 12 inches tall.
2. Soybeans from the first to the third trifoliate stage.
3. Dry beans from the one-leaf to the three-leaf stage.
4. Sugar beets in the two-leaf to the eight-leaf stage.
Outlook will not kill emerged weeds, but it should kill germinating annual grasses and small-seeded broadleaf weeds.

With the recent heavy rainfall, some fields have crusted over, creating poor emergence. Make sure you are out checking your fields to see if a replant is needed.

LeRoy, MN

If you spray your pre-emerge chemical (e.g. SureStart, TripleFlex, Verdict, OpTill, or Valor) and it’s dry, you don’t need to worry about it disappearing. It will stay there until it rains and give you later residual.

Most of the corn in the area is at or near the two-leaf stage, which is the perfect timing for an application of Halex GT. Halex GT fits the field that has emerging weeds and gives you lasting residual. AMS and NIS are required when applying this product.
Dave Timmerman
There are a few producers looking at some replanting in both corn and soybeans due to heavy crusting. Some of these areas can be helped by rotary hoeing, but there are a few cases where replanting will be necessary.

Olivia, MN

We’re getting a lot of questions about slow-emerging corn after the hard rains we had on May 5th. If the corn is not leafing out under the surface, I’d urge you to have a little more patience and wait a few more days before using the rotary hoe. Chances are you would be doing more harm than good going out at this stage.
Jeff Keltgen
Post-emerge spraying on early planted corn should start very soon. Use Laudis at 2-3 oz. to help with your broadleaf weeds. Tankmix with Roundup and make sure you use MSO at a minimum of 1/2 gallon per 100 gallons of water and AMS at 17 pounds per 100 gallons of water.

With the wind blowing 40 miles per hour today, spraying is not a good idea.

Winthrop, MN

If your corn has emerged, you can still apply your TripleFlex or SureStart in corn up to 11 inches tall. It will be beneficial to tankmix Roundup in with these products to help clean up any emerged weeds.
Dean Christiansen
If you missed the window of opportunity to apply pre-emerge soybean herbicides, Warrant can be applied post-emerge and still give you the residual of a pre-emerge herbicide.
Dave Worth
We’re starting to see cutworms in sugar beets. Apply Silencer at 3.2 oz. to control this pest.

Many guys are done spraying in crop, but don’t forget to continue to scouting for bugs and diseases. Now is also a great time to do some tissue sampling to see if your crop needs any additional nutrients.

A lot of producers are still considering using a fungicide on their winter wheat. One thing to remember is that if the crop is past the flag leaf stage, do not use a strobilurin product like Headline. If the head is out, you could increase DON levels.

When adding Impact, Callisto, or Laudis to Roundup, always add 1 quart of nonionic surfactant per 100 gallons of water. These products respond well to higher surfactant loads, and the NIS will also complement your Roundup uptake.

RyzUp SmartGrass is now labeled on silage corn. Adding 0.3 oz. per acre in with your Roundup will give it an early jump.

Spraying WideMatch and Everest, Accurate Extra and a gallon of Impact on winter wheat will control rattails.

At this time, we are not advising spraying wheat herbicides because of the high temperatures and lack of moisture. However, Monday looks cooler. Hopefully, we will get some rain this weekend.

In the wheat and barley fields, tan spot is showing up everywhere. Aster leafhoppers are thick, along with cutworm moths. We need to tankmix fungicide and insecticide in every application of our wheat spray. Evito, Stratego or Headline would be the best choice for longevity control.

Soybeans are going in the ground, so start thinking about getting your pre-emerge herbicides ready to go. Most have to be on before the crop is up.
Gene Mittleider

Considering the rapid rate at which soybeans are being put into the ground, your chance of getting pre-emerge herbicide down is passing by. A good post-emerge chemical to add to your tank mix would be Cobra at a rate of 12.5 oz./ac to help control many broadleaf weeds.

Foxtail barley seems to be a problem in some winter wheat fields. Rimfire Max at 3 oz. tankmixed with two quarts of NIS per 100 gallons of water plus 28% at two quarts per acre can be applied up to flag leaf emergence.

There have been lots of reports of insects around already. When spraying your wheat for weeds, throw in a pyrethroid insecticide like Warrior, Mustang Max or Silencer. These products are relatively inexpensive and will provide you good residual insect control.

Bertrand, MO

There is a high concentration of corn earworm moths in Southeast Missouri. A product like Prevathon would be a good choice at a 20 oz. rate applied with your fungicide at full tassel.
Albert Duenne
With rainfall nowhere in sight, farmers are trying to beat the odds and are planting beans in dust. We’re not anticipating much of a crop unless it rains soon.
Darryl Wolford
Reports are coming in from Arkansas that high insect numbers continue to be an issue in corn and soybeans. With soybean planting in Missouri running behind, farmers should continue to monitor for worms in their fields. The soybeans that have been planted are between the emerging and V3 stages now and are very vulnerable to insect damage at this time.

We’re hearing reports of wireworms in winter wheat, but it shouldn’t be anything to be too worried about. They generally are more damaging in spring crops when the roots are small and vulnerable. These warm days should drive them deeper into the soil. Seed treatments like Cruiser and Gaucho at high rates are best for spring crops.

When spraying alfalfa with Roundup prior to cutting, remember to watch the weather pattern because it needs to be cut three days after the application. If rain is in the forecast, your hay will get rained on.
