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.

2018 Field Plot Summaries for Wheat Disease Management Trials
The wheat disease management field experiments conducted in the 2018 growing season evaluated several experimental and commercially available fungicides for managing foliar, head or root diseases of spring wheat. Foliar and spike/head diseases incidence and severity were assessed. The field experiments were implemented at Volga Research Farm and Northeast Research Farm (NERF) near South Shore, SD. Results of the same experiment may vary between Volga and Northeast due to environmental differences between the two locations.
Weeds Around Spruce Seedlings?
I have many producers call wanting a control for the broadleaf weeds coming up around their young Colorado and Black Hills spruce seedlings. At this time of year we are looking at post-emergence herbicides to control weeds that have become established.

Woodpeckers Attacking Bur Oaks
Woodpeckers have been seen across the region chipping away at the bark of young bur oak. The woodpeckers can shred most of the bark from young trees, enough that the trees are killed by this injury.
Woody Weeds: Eastern Red Cedar
While eastern red cedar (Juniperus virginiana) is native to South Dakota, and has many positive qualities, it has become a problem species over large areas of the Great Plains.
