Gibberella and Fusarium Ear Rots Developing in Corn
Corn ear rots are one of the last diseases to scout for in the corn growing season, and sometimes they are ignored or forgotten entirely. Ear rots can cause yield loss in the form of grain quality at harvest, but also cause losses during storage.
Assess for Corn Stalk Rots
Several corn fields are beginning to show stalk rot and top dieback symptoms. Stalk rots cause the entire plant to die prematurely, which can lead to plants lodging under windy conditions making harvesting problematic.
Southern Rust Developing Late in Corn
Southern rust was found in a few corn fields scouted last week. This rust is developing very late in the season and therefore its impact on corn yield will be minimal.
Early Yellowing in a Soybean Field May Indicate Presence of the Soybean Cyst Nematode
Some portions of soybean fields may show clusters of plants yellowing while the rest of the field is still green. One of the factors that could lead to soybean plants showing early yellowing in clusters is soybean cyst nematode (SCN).
Sudden Death Syndrome Starting to Develop in Soybeans
Sudden death syndrome of soybean is starting to develop in soybean fields in South Dakota. Fields currently being found with sudden death syndrome have symptomatic plants scattered within the field, but continued disease development may lead to larger clusters of infected plants.
