SDSU Research Shows Effects Of Volunteer Corn In Corn And Soybeans
In 2007, researchers at South Dakota State University indicated that volunteer corn is much less competitive in corn than soybean. The South Dakota study (Alms et al. 2007) evaluated the full season effect of a range of volunteer corn densities (800-14,000 plants/acre) on both corn and soybean and reported yield losses that ranged from 0% to 13% in corn and 0% to 54% in soybean.

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.
Low-Level Aphid Populations Present in Wheat
Reports of aphid populations in wheat fields have been slowly increasing in the past week. Most of these populations are well below the economic threshold, but there is a potential for them to increase.
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.
Army Cutworm Moths Among the Recently Reported Western Bean Cutworm Moths
Last week, we published an article about the presence of western bean cutworm moths being very abundant throughout Central and Western South Dakota. However, when talking with an entomologist from a neighboring state, they suggested the moths could also be army cutworm moths.
