Three soybean fields with yellowing issues due to potassium deficiency, iron deficiency chlorosis and soybean cyst nematode.

What Is Causing Soybeans to Yellow at This Time?

Recently scouted soybean fields were observed with yellowing plants, and one field was found to have plants dying prematurely. Learn some of the factors that may cause soybean plants to yellow at this time in the growing season.

Drought Conditions May Increase Soybean Cyst Nematode Population in Soil

Moisture stress coupled with above-normal temperatures have been linked with increased soybean cyst nematode populations in the soil. In order to keep populations in the soil below the yield-reducing levels, there are a few management practices which can be used.

Scout for Charcoal Rot in Early Senescing Parts of the Field

The drought conditions in the past few weeks have led to some soybean fields senescing early. However, some of the early senescing may be due charcoal rot.

Drought Stress or Stem Canker Killing Soybean Plants?

Several soybean fields scouted in a number of Eastern counties have plants dying or dropping leaves prematurely. While the majority of these fields have drought stress causing early senescence, a few fields have also stem canker developing

Brown Wheat Mite Affecting South Dakota Wheat

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.

Avoiding Field Fires During Fall Harvest

With dry and drought conditions in the late summer and fall, crops dry down rapidly and harvest starts early. The climate outlook may be favorable for an uninterrupted run at harvest. However, the risk of fires during harvest is always a concern for farmers.
