Crops

As South Dakota’s farmers know, many factors go into raising successful crops. SDSU Extension’s team works to boost farmers’ yields and profits by providing access to research-based information, resources and local agronomic information.

Collaborating with South Dakota Agricultural Experiment Station at SDSU throughout the growing season, our team showcases local data collected from test plots in a field near you.

Variety Trial Results

Crop performance testing results are released annually through the activities of SDSU Extension and the South Dakota Agricultural Experiment Station at SDSU.

Fusarium Root and Crown Rot Developing in Corn

A few corn fields scouted in Brookings County were found with Fusarium root rot at low levels. Infected plants were wilting and upon splitting of the lower nodes revealed brown discoloration of the pith. Root and crown rots developing in corn after the seedling stage are usually caused by Fusarium spp. and can be enhanced by injury to the roots or crown, mainly by insect feeding.

Watch for True Armyworms in Wheat

This week we observed some true armyworm caterpillars in winter wheat fields. The caterpillars were still relatively small, which means they will continue feeding for some time. So far, the true armyworm caterpillars were still feeding on the leaves of the nearly mature wheat, but they have the potential to also clip heads off of the plants.
