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.

A Case of Mistaken Caterpillar Identity

Tweets about European corn borer (Ostrinia nubilalis) caterpillars in the stems of conventional corn and feeding in the whorls of corn are crossing my Twitter feed. Unfortunately, there is a problem with some of these tweets. Not all of the caterpillars that are being identified as European corn borer caterpillars are actually European corn borer caterpillars!

Storing Wet and Modified Distillers Grains

One of the primary challenges for livestock producers in the coming months could very well be feedstuff cost and availability due to the fact that the corn planted acreage and crop progress are both well behind normal benchmarks. One opportunity that might help cattle feeders proactively secure feed supplies would be storing wet or modified distiller’s grains now to be fed at a later date.
