Powdery Mildew: A Disease Concern in Field Peas

Producers of field peas may need to scout for powdery mildew this year. Powdery mildew is a late-season fungal disease that can impact peas if weather conditions are conducive. However, this disease can also occur in early planted fields in South Dakota under the right environmental conditions and when the crop canopy is heavy.

Precision Agriculture and Zone Management

Precision agriculture tools can address the variations in a production system to enhance plant growth and crop yield. Zone management controls the variable rate of inputs for optimal performance within a defined field zone.

Left: Soil from long-term no-till field, exhibiting good soil aggregation through clumping and smaller pieces of soil. Right: Soil from conventionally managed field that included tillage and crop residue removal. Notice the soil is lighter brown, indicating lower organic matter, and the pieces of soil are in larger chunks with no visible indication of clumping or structure.

Organic Agronomy Starting to Impact

For decades scientists have known that a handful of soil contained more micro-biological organisms than the number of humans on earth. Science is just beginning to discover these organisms and learn about their functions and contribution to their soil ecosystem.

White Mold and Sudden Death Syndrome Starting to Develop

White mold and sudden death syndrome are starting to develop in a number of soybean fields. These two diseases develop starting at the soybean flowering growth stage and can occur throughout the rest of the soybean growing season.
