Winter Wheat Diseases Update: Fungal Diseases and Barley Yellow Dwarf Developing

Tan spot and powdery mildew as well as barley yellow dwarf were found developing at low levels in winter wheat fields scouted the week of May 24, 2020.

Low Temperature Effects on Winter Wheat

Low temperatures during the early morning hours of May 9–11, 2020 may have had detrimental effects on winter wheat in some areas of South Dakota. However, cooler spring temperatures that have slowed the winter wheat development this year may have actually been beneficial to S.D. producers, as later-maturing wheat is not as susceptible to injury from freezing temperatures.

Does Early Fungicide at Tillering Result in a Profitable Yield?

Tan spot and powdery mildew pathogens are two residue-borne pathogens that can infect wheat early in the season. These diseases can lead to poor tillering, and their continued development can lead to yield loss.

Peas Offer Options in 2020

Current events have made decisions around crop options very difficult this spring. Field peas are an option that may have a fit for some producers.

Prairie Dog Management in South Dakota

Prairie dogs are an important component of the grassland ecosystem. They feed on grasses and forbs, as well as seeds and some insects. They can consume large amounts of vegetation. This is a problem for livestock producers as they compete with livestock for forage.

Prussic Acid Poisoning

As the first frost date approaches, producers often have concerns about the risk of prussic acid poisoning in livestock. Certain forage plants, especially sorghums and related species are associated with an increased risk of death loss because of prussic acid poisoning.

Broad-Headed Bugs in Soybean: Should You Be Worried?

This week we received a report of insects infesting a soybean field. However, they weren’t insects that we generally think of when the term "soybean insect pests" comes up.
