Fall Frost and September Climate Outlook for 2019

September 2019 has been pleasantly warmer than usual, and our crops need every bit of that warmth to reach maturity before our first frost arrives. Fortunately, temperatures have cooled slightly this week but just to near average for this time of year.

Pre-Plant Disease Management Considerations

If the forecast holds true, it looks like it is going to be another year of excessive soil moisture and possible flooding come this spring. The increased level of soil moisture has implications with regards to plant stand establishment as well as root rot and nematode infestations.

Black Grass Bug Activity Expected in Coming Weeks

Spring green-up is the time to be watching for black grass bug activity. Large populations of this early-season pest can cause severe damage to pasture (up to 90% forage reduction) and infest the edges of wheat fields.

Chloride Fertilizers May Be Beneficial in Spring Wheat Production

Chloride, the ionic form of chlorine, although not considered an essential nutrient, has long been observed to be highly beneficial to field crops. Chloride is known to play an essential role in plant development and osmoregulation.

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.

Wheat Streak Mosaic Disease Developing in Winter Wheat

Although the majority of winter wheat in the state is rated good to excellent in the recent USDA-NASS report, a few winter wheat fields in Central South Dakota have been diagnosed with wheat streak mosaic disease (WSMD) caused by wheat streak mosaic virus (WSMV).
