2018 Field Plot Summaries for Oat and Sorghum Foliar Disease Management Trials
An oat crown rust integrated management trial and a sorghum foliar fungicide trials were conducted to determine the efficacy of fungicides to manage crown rust and fungal diseases in oat and sorghum respectively. Crown rust is one of the most devastating diseases of oat in the state. Stragego fungicide was applied at three different timings to determine the most effective timing for crown rust management. For sorghum, the study investigated the efficacy of two different rates of Nexicor for managing sorghum foliar diseases. The oat field experiment was maintained at Northeast Research Farm (NERF), Southeast research farm (SERF) and Volga research farm. The sorghum experiment was at Volga.
Utilize a Fungicide For Crown Rust Prevention in Oats
If you are growing oats this year for grain, be sure to scout and plan a fungicide application to protect the oats from crown rust.
SDSU Extension to Kick Off Crop Hour Webinar Series in January
January 10, 2022
SDSU Extension will, once again, deliver a series of virtual Crop Hour webinars this winter. Starting Jan. 11, every Tuesday through Thursday from 10:00 a.m.-11:00 a.m. CST, participants are invited to take their coffee break online to hear the latest in crop management and agronomic research from SDSU Extension.
Creating Management Zones Using Electrical Conductivity
The first step to practicing zone management is to identify the variations that control yield. There are various methods for characterizing soil variations within a field, and among them, electrical conductivity measurement is one of the most-reliable.
Midwest Cover Crops Council Releases Third Edition Cover Crops Field Guide

Cover crops are used to slow erosion, improve soil health and capture nutrients. From planting to termination, growers face many production decisions, however.
Determining an Economically Optimal Nitrogen Rate for Corn in 2022
While we can't know what the prices of corn and nitrogen fertilizer will be next year, it is very important to understand how the level of both prices will influence corn profitability for 2022.
Fall Soil Sampling
With fertilizer prices on the rise, it’s more important than ever to understand your soil test levels and crop response to applied fertilizers. Fall is a great time to soil sample before freeze up.
Understanding Hay Inoculants and Preservatives on ‘Dry’ Hay
As haying season approaches, producers across South Dakota will begin preparing to get out the baler. In recent years, it has been quite difficult for many producers to put up quality, dry hay. This often results in growers considering using inoculants and hay preservatives.
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.
How Late is Too Late for the Last Alfalfa Cutting?
With a very challenging growing season and flooding across parts of South Dakota, many growers have struggled to harvest high quality forages in-between rains this summer.
