WARNING: WHITE MOLD FOUND in soybean fields!

We have found areas of white mold starting aggressively in area soybean fields. It is too late to use the herbicide Cobra®, but you could us a fungicide such as Domark®, at 5 oz. per acre, to help slow down the progression of this devastating disease. It is also recommended to add in 6.4 oz. per acre of MasterLock® (a new premix of Interlock® and Preference®) to aid in the dispersal of the fungicide on the soybean plants. Below are some photos to assist you in determining if you have any white mold in your fields. (Click photos to enlarge them.) Please let us know if you need any help scouting your fields.

Pockets of soybean aphids found…

We were out scouting some soybean fields north of Galesville today and found some pockets of aphid pressure. Please remember to be checking your fields on a regular basis.

On a related note, here is a pop quiz for the day: Is the insect pictured below a friend or foe?

Lady beetle Larvae

The answer? Friend! This little guy is actually the larval stage of the lady beetle. The lady beetle eats soybean aphids. Remember with the insects the stages are egg, larvae, pupa, and adult.

Mauston Grain Plant Fully Operational

The Mauston Grain Plant is up and running and ready to meet all of your needs during the upcoming fall harvest.  While we did close the plant recently to make repairs, the site is once again fully operational.  Customers shouldn’t notice any changes or delays.

We look forward to working with you during the busy harvest season ahead.  If you have any questions or concerns regarding the Mauston Grain Plant, please call Ray Demaskie at (608) 847-5212 or David Rappa at (608) 372-2090.

Insect activity found today…

Near Galesville today I found my first Western Bean Cutworm Egg Mass. The moth counts are very low this year. We put out 5 pheromone traps and have found very few this season. I also found a fair number of Corn Rootworm beetles feeding on the fresh silks today. Please keep a watchful eye on your corn fields during the critical pollination phase. The published threshold is “when silk clipping is occurring on 25% or more of the plants during pollen shed.” Also, if this field will be corn next year, it is best to plan your management strategy to combat this pest now due to the fact that they will be laying eggs now to attack next year’s corn crop. Please let us know if you have questions on any of these issues. Thank you.

Mauston Grain Plant Temporarily Closed

Due to unforeseen circumstances, the Mauston grain plant will be out of service for an indefinite length of time. We hope to have the plant up and running as soon as possible. We are sorry for any inconveniences this may cause you. Please check back here for further updates on when the plant will re-open.

Due to the Mauston location being closed, we will be handling grain services for Mauston out of our other locations. We will be accepting wheat at our Adams location and oats at our West Salem location. Please call our marketing staff at 608-339-0357 to arrange transportation, or if you have any questions on pricing at the other facilities. If you have any other questions or concerns, you can contact David Rappa at 608-547-6149.

Crop Update


Our black light traps are showing low to very low levels of western bean cutworm moths, European corn borer, and corn earworm, especially compared to the levels we were finding this time last year. We have found a few corn leaf aphids on some of the heavier ground in our area so be sure to be monitoring your fields for this pest as the summer progresses. Much of the corn in our area is at the tail end of pollination and is looking good. Low levels of rust can be found in most all of the fields in our area. Anthracnose leaf spot is common in fields that are corn after corn. We have only found a few fields with trace amounts of Northern corn leaf blight to date, but with wet weather on the forecast it is likely to spread.


Japanese beetle, green clover worm, aphids have been the main insects we have been finding these past few weeks, but no fields have reached economic thresholds yet. Be vigilant in scouting for aphids as the extended forecast of cool weather will be very conducive to aphid reproduction. University thresholds are 250 aphids pre-plant which may sound like a lot, but when the population can double every few days it does not take very long for a field to become infected. Septoria brown spot is slowly building in the lower canopy of many of the soybean fields in our area. Consider a foliar fungicide if you have moderate or heavy disease pressure at this time. The key time for fungicide on soybeans is the R1 (beginning flower) to R3 (beginning pod) stage. Many of our fields are in the R3 stage to R4 (full pod).


Late blight continues to be a problem and is slowly but surely spreading with each week, bringing one or two more fields found to have been infected. So continue to apply fungicide on your scheduled interval being sure to add premium late blight material especially on the weeks of cool wet weather like we have been having. We are currently in the midst of second generation Colorado potato beetles with adults already laying eggs and larvae hatching. Some of the petiole numbers are starting to crash as the crop begins to pour energy into the tubers. We have been checking tubers for shape and size last week and this week to see if an MH30 application is needed to correct the shape of the tubers.
