Distillers’ Grains and Rumen Papillae Growth

Distillers grains are without a doubt one of the most versatile ruminant feedstuffs. Aside from their high concentration of sought-after nutrients (i.e. protein, energy, phosphorus), their impact on the digestibility of other feeds is minimal. In fact, by not interfering with the digestion particularly of structural carbohydrates, they allow for more energy to be obtained from forages.

Soybean Rolling: Yield Effects

Land rolling soybeans has become a common management practice in many areas of South Dakota. The main reason for using a land roller on soybean fields is to push down rocks and level the soil surface for harvest, in theory reducing the amount of rocks and other debris that can potentially damage a combine header.

Common Stalk Borer Activity Update: June 6, 2019

It finally warmed up and the insects have definitely become more active. However, our calculations indicate that not enough degree days have been accumulated for common stalk borer activity to warrant any scouting, but spraying field edges should be avoided through most of South Dakota in the next week.

Alfalfa Weevil Activity: June 7, 2019

Quite a few degree days were accumulated over the course of the last week. Alfalfa fields should be closely monitored for alfalfa weevil activity for the next couple of weeks, even in areas where degree days indicate the alfalfa weevils are pupating.

Watch for Bean Leaf Beetles

Some soybean in South Dakota has emerged and it is already being attacked by early-season bean leaf beetles. So far, observations of adult bean leaf beetles emerging from fields and defoliation of soybean have been in Southeastern South Dakota.

Iron: An Important Mineral

You may have heard or know someone who always speaks about being fatigued, weaker than they once were, or have a difficult time regulating their body temperature. There is a chance that they may be iron deficient.

Cancellation of Several Neonicotinoids

On May 20, 2019, the United States Environmental Protection Agency announced the cancellation of registrations for 12 products that contain neonicotinoid insecticides. The cancellation of the product registrations was voluntarily requested by the companies that had registered the products.

Scout Soybeans for Bean Leaf Beetle Feeding

We are receiving numerous reports and also observing very large bean leaf beetle populations this year. As a result, there is also a lot of concern about soybean defoliation due to the emergence and subsequent feeding by the overwintering adult population.

Aphid Populations Being Observed in Wheat

During the past couple of weeks, reports of aphid populations in wheat fields have slowly been increasing. Typically, the initial aphid populations are observed earlier in the season, but the 2019 spring may have delayed infestations.

Ditch Hay: Harvesting, Quality, and Feeding

Using ditch hay to feed cattle is a common practice across the U.S. It provides livestock producers with a source of readily available forage, which can be very useful, particularly during feed shortages.
