South Dakota State University will host the third Edgar S. McFadden Symposium on Wheat Improvement on May 1- 2, 2018.
When precision agriculture comes into a conversation a few questions arise. Three of those questions might be: What is precision agriculture? How does precision agriculture make our farm more profitable? What do I do with all this data?
Recent USDA data shows that during the past 3 years acres devoted to wheat production continue declining in both South Dakota and North Dakota (USDA, 2018). South Dakota wheat acres experienced a remarkable decrease of 31.5% during the past 3 years, compared with a relatively mild drop of 16.4% by North Dakota.

Due to wheat streak mosaic disease showing up in wheat fields across South Dakota in 2017, many wheat growers wonder if they need to worry about the disease spreading this winter and wheat streak mosaic virus showing up in their fields spring 2018.
While scouting wheat fields throughout South Dakota, we have started noticing the presence of bleached heads scattered throughout many different fields. These discolored heads are the result of an infestation of the wheat stem maggot.
Barley yellow dwarf is starting to develop in winter wheat. Barley yellow dwarf is caused by the Barley yellow dwarf virus (BYDV). This disease usually becomes more distinct at flag leaf emergence. A typical symptom of Barley yellow dwarf is the purplish-yellow color of infected leaves, especially the flag leaf.
Many wheat producers in South Dakota have adopted more intensive management practices in the last few years, including an early season application of fungicide and, in some cases, insecticide.
In South Dakota, the most commonly encountered mites in wheat are wheat curl mite and brown wheat mite. In addition to feeding, wheat curl mites are vectors of Wheat streak mosaic virus. Brown wheat mites can build up large populations and injure wheat through feeding. There are other species of mites that may also be observed in wheat, but generally do not reach populations large enough to cause significant injury.
Recently, there have been reports of brown wheat mites throughout central and western South Dakota. The brown wheat mite is generally more of an issue in the drier parts of the state, or in areas experiencing drought. The feeding injury caused by these mites leaves white or brown spots that are referred to as stippling.
