Soybean Aphid Alert!

Attention! Soybean Aphid Alert! Soybean aphids have started to hit our area. We found out some fields are at threshold. I just visited with a grower whose fields are in Southern Adams county and Northern Columbia county and he has soybeans fields that need to get sprayed. Be sure to use a minimum of 15 gallons of water and a lot of pressure to get good coverage. I have had very good results using Leverage 360 insecticide in the past at the 2.8 oz rate. If you are spraying the field consider tank mixing in a foliar micronutrient package, such as Max in ZMB, and/or a foliar fungicide such as Stratego YLD at 4 oz. Please contact one of our agronomists to find the best recipe for your acres. Thanks and be safe out there!

UPDATE (5:36pm): In talking with our team up in Galesville this afternoon it sounds like the Soybean aphids are very bad up on the Trempealeau Prairie, just west and a little north of our Galesville location. They are ordering in more Leverage to combat this pest. Please check your fields on a regular basis. Typically the threshold is at 250 aphids per plant.

July Crop Update

Potatoes

Late blight has been found in a potato field west of Plainfield last Friday, 6/28. With late blight in the area it is important to step up your fungicide program by shortening intervals and using premium products. Be sure to be scouting shaded East borders as they remain wetter later in the day and are therefore at a higher risk of infection by late blight especially if you are spraying by air only. This week we are fighting 3rd and 4th instar Colorado potato beetle larvae who survived earlier insecticide applications especially on edges.

Corn

In corn, we are making sure that the fields are weed free and continue monitoring for foliar diseases and insects. Our black light trap moth counts have remained low for most corn insects. We are seeing quite a few rose chafer beetles in several fields in the area, yet we are not seeing much feeding from them at all but will continue to monitor them.

Soybeans

In soybeans, we are cleaning up weeds across most of the area this week and monitoring fields for early insects and disease.

More wet weather this week (June 10-14)

More wet weather ahead in the forecast makes for tough hay drying weather, and more rain is the last thing we need on some of the wetter ground that we have been waiting to plant all season long. Also, this cool wet weather favors pythium in the soybeans and we have been finding some dead seedlings in several fields across the area.

In the potatoes, the second hilling is getting finished up and fields should be checked for weed escapes. Also, Colorado potato beetles are laying eggs in full force, expect the first generation of larvae to emerge next week. The black light traps are extremely quiet right now with only a few cutworm moths.

Looking forward into the future, consider doing some nematode testing on your farm this year. Nematodes are microscopic worms that exist in almost all soils and, while many are harmless or even beneficial, there are several plant parasitic nematodes that may be secretly robbing yield year after year. Many of you are probably familiar with soybean cyst nematode, but there are many other nematodes that affect other crops. Nematodes that are particularly damaging in corn are dagger, lance, root lesion, and needle.

At Pest Pros, a division of Allied Cooperative, we sample and test soils for nematodes to measure a fields relative risk for nematodes in the future. Such information can help you identify and begin to manage a nematode problem. Sampling can also help you asses your Poncho/Votivo and Avicta programs. For more information on nematode testing, contact the Pest Pros lab at (715) 335-4046.

On Demand Soybean System

Gerry Fanta and Sally Turpin are seen here treating bulk soybeans with our new On Demand soybean system! This year more than any other it is CRITICAL to have fungicide on your soybean seed. With the wet conditions in the fields, seedling rot diseases are going to be a constant threat this season.

In Galesville today…

Today, our summer agronomy intern, O’Bryan Decker, and I got out in the field to do some crop scouting in Ettrick, WI. We also stopped by the Galesville agronomy division where I took a few shots of the crew working on their equipment. It’s been so wet there that they can’t get out to do any field work. Check out the photos below.

Watch out for pests in corn and potatoes this week (May 27-31)

This week we have soybeans emerging, and we’re on the lookout for black cutworms in the corn. In potatoes, it is mostly weed scouting at this point, but we are finding first generation adult Colorado potato beetles. Also, some of the severe weather has left some crops with wind damage, especially the newly emerged soybeans.
