USDA’s weekly crop progress report, due for release Monday afternoon, will be scrutinized for any sign of weather stress. Last week’s publication contributed to a rally in wheat prices by indicating a sharp decline in spring wheat crop conditions.
Disease watch is on in the Dakotas, now that crops are emerging. Environmental conditions influence which diseases may be present each growing season. With razor thin margins in 2017, careful analysis of fungicide inputs for corn and soybeans is crucial.
Growers should assess some of the risk factors for disease when determining whether a fungicide application is likely to deliver a return on investment.
Jeff Spieler, DEKALB Asgrow Technical Agronomist, based near Lennox, South Dakota, suggests that growers should keep field history in mind – along with weather – which has been highly variable for the region. In soybeans, for example, some of the usual disease suspects include Frog Eye Leaf Spot and Septoria Brown Spot.

For corn, fungicides can help protect stalk integrity, which is especially critical for late planted, late-harvested corn. Spieler says now is the time to keep an eye out for disease pressure – and scout early.

Most fungal diseases in corn and soybeans develop when conditions are wet or humid with moderate temperatures.
