Monitor Canola Fields for False Chinch Bug Activity

While scouting canola this week, I came across a field that had plants along the edge that looked like they were suffering from drought stress, but given the recent rain I doubted that to be the case. Closer inspection of the stressed plants indicated that they were covered in false chinch bugs. Although false chinch bugs are not normally an issue in canola, very large populations do have the potential to reduce yield.

Diseases in Winter Wheat Imply High Inoculum for Spring Wheat

Winter wheat is past the need for an in-season fungicide application. However, many spring wheat fields are yet to flower, making them prone to disease development. A few diseases, including leaf rust, stripe rust, and Fusarium head blight have developed in winter wheat. This implies that there is enough inoculum available for these diseases to develop in spring wheat; especially East River, where rainfall has been frequent.

Continue Scouting Wheat for Aphid Populations

Aphid populations in winter wheat continue to be observed in South Dakota. The major questions now are whether or not aphid populations are at economic threshold and if spraying is really necessary.

Storing Wet and Modified Distillers Grains

One of the primary challenges for livestock producers in the coming months could very well be feedstuff cost and availability due to the fact that the corn planted acreage and crop progress are both well behind normal benchmarks. One opportunity that might help cattle feeders proactively secure feed supplies would be storing wet or modified distiller’s grains now to be fed at a later date.

Spot Treatment Options for State Noxious Plants

When controlling grassland weeds, the mindset of row crop weed control may be put into practice too often. In most cases, broadcast control of weeds in grasslands is rarely necessary. Most often, spot treatment can be used more effectively to manage the noxious and invading weeds.

Soybean Gall Midge Larvae Found in South Dakota

Although we have yet to capture any adult soybean gall midges, the reports and observations of soybean gall midge larvae in soybean are pouring in this week. In Clay and Union counties, infested soybeans are now showing signs, with plants beginning to wilt and die in some cases.

Current Weather Conditions Are Conducive White Mold Development in Soybeans

Frequent rains and overcast conditions continue to occur in South Dakota’s main soybean growing counties. These conditions favor white mold development. In some of these counties, soybean is already at R1, which is also the best timing for fungicide application targeting white mold control.

Monitor Soybean for Defoliating Insects

While scouting soybean this week I noticed quite a few defoliating insects that were present in the field. So far, the feeding injury is minimal, but it is a reminder that we need to be diligent in monitoring leaves for defoliation and fields for these insect pests.

Making a Safe Salad Dressing

Have you ever wondered whether a homemade salad dressing is safe when you’re eating it at your local picnic, potluck dinner, or at a family get together? In this article, we will explore what food safety characteristics need to be addressed to ensure that a salad dressing is made safely.
