Winter Wheat Disease Update: Wheat Streak Mosaic and Tan Spot Developing at Low Level

Winter wheat fields scouted the week of May 27, 2019 in South Central South Dakota were found with wheat streak mosaic virus and tan spot developing at very low levels. Both diseases were found in non-rotated wheat fields.

Delayed Planting Challenges: Cover Crop Considerations

High waters and saturated soils across many counties in South Dakota have producers worried about getting their crops planted in a timely manner this spring. In many areas, typical cash crops will not be a possibility. Producers may need to develop alternative plans.

Delayed Planting Challenges: Alternative Forages

With the excessively wet planting conditions much of South Dakota is now experiencing, many producers are looking for “Plan B” to meet forage needs for their livestock, or as a commodity that can be marketed to livestock producers.

Effecting Change Towards Economic Growth

During 2018 the main driver for South Dakota's economic growth continued to be agriculture. It is still the number one industry, with almost $20 billion in impact yearly. In today’s uncertain economic environment, two things can help farmers succeed: information and knowledge.

South Dakota Herbicide Damage

As the spray season starts, it is always good to be aware of resources and testing facilities where you can send in possible herbicide-affected plant samples. SDSU Extension offers suggestions on how to handle possible herbicide damage situations as well as recommended labs that receive plant matter samples to test for herbicide residues.

Diagnosing Early Diseases in Winter Wheat

Winter wheat progress is relatively behind the five-year average given the long winter season and low spring temperatures. However, it is important to scout and diagnose early-season diseases in winter wheat to determine the need for an early season fungicide.

Herbicide Considerations for Cover Crop Planting in 2019

Long residual pre-emergent or early post-emergent herbicides may cause stand reduction or complete failure of cover crops. Depending on efficacy of the herbicide, each situation can both affect in-season and/or post-harvest cover crop establishment.

Bacterial Leaf Blight Developing in Winter Wheat

Recent winter wheat scouting found bacterial leaf blight developing in some fields. Bacterial leaf blight is caused by the bacteria, Pseudomonas syringae pv. syringae. The disease develops under frequent rains between 59 and 77 degrees Fahrenheit.
