Instinct HL and Nitrogen Management Effect on Winter Wheat Yield

Nitrogen (N) additives to control N losses through volatilization, denitrification, and leaching are widely used in the Midwest. Slowing the conversion of nitrogen fertilizers to nitrate may lessen leaching and denitrification losses if precipitation or soil becomes saturated.

Wet Feet in Wheat

Given the widespread wet conditions present this spring, there are many areas in winter wheat fields with both ponding and saturated (or waterlogged) soils. Producers may want to consider soil conditions and evaluate extended weather forecasts when deciding whether or not to retain a winter wheat this spring.

South Dakota Herbicide Damage

As the spray season starts, it is always good to be aware of resources and testing facilities where you can send in possible herbicide-affected plant samples. SDSU Extension offers suggestions on how to handle possible herbicide damage situations as well as recommended labs that receive plant matter samples to test for herbicide residues.

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 Soybeans: Plant Disease and Fungicide Trials

This is a summary of soybean field research studies that were conducted in 2018. The purpose of these studies was to assess efficacies of fungicides for foliar disease management and nematicides/seed treatment products for nematode management. The studies were conducted on growers’ land in Brookings and Volga Research Farm.
