Late-Season Soybean Diseases: Know what’s killing your soybeans

Late-season soybean diseases can sometimes be mistaken for natural senescence. A closer look at the stems and roots of dying plants and the pattern displayed by dead plants in the field may reveal root or stem rots going on. In order to devise effective management practices for future soybean seasons, it is important to determine the cause of early soybean plants death.

Soybean Pests: Bean Leaf Beetles and Bean Pod Mottle Virus

With the number of bean leaf beetle observations in soybean fields during 2016, the need for monitoring soybean for Bean pod mottle virus (BPMV) development increases. Bean pod mottle virus was first identified in South Dakota in 1998, and is recognized as a very economically important disease in soybean due to the potential for it to cause devastating losses to soybean yields.

Forecasted Cold Temperatures Can Be Used To Cool Down Stored Grain

If temperatures are forecasted as being well below freezing, it would probably be a good time to start thinking about cooling stored grain. Cooling grain reduces the activity of stored grain insect pests and suppresses any mold growth that may otherwise occur.

Gall Midge Larvae in Soybean Stems

Gall midge larvae were observed recently in soybean stems from a field in South Dakota. These insects were found under the epidermis of the stem that was slightly above the soil line.

Bacterial Leaf Streak Developing at Low Level in Winter Wheat

A few winter wheat fields were found with bacterial leaf streak starting to develop at low levels. Bacterial leaf streak is usually observed starting from flag leaf growth stage. It can be severe on the upper leaves when there is prolonged leaf wetness resulting from frequent rains.

Map of South Dakota showing Fusarium head blight risk. Green indicates low risk, yellow moderate risk, and red high risk. Most of the state is green except for scattered, yellow areas within Edmunds, Faulk, Hyde, Hand, Buffalo, Jerauld, Brule, Aurora, Turner, Lincoln, McCook, Lake, Brookings, and Kingsbury counties. Some red, high risk areas are in Buffalo, Brule, Hyde, and Minnehaha counties.

Fusarium Head Blight Predicted Risk for Spring Wheat

Most of the spring wheat is at or will soon be at flowering. One disease that can develop in wheat at this growth stage is fusarium head blight (FHB or scab).
