Investigation of Soybean Seed Treatment and Inoculant in Southeastern SD, 2018

Soybean seed treatment products are widely utilized by many farmers in southeastern South Dakota and the surrounding area. These products often consist of an insecticide/fungicide combination, and/or inoculant that is mixed and placed on the seed as a pre-treatment before the grower plants the crop.

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.

Fungicide Seed Treatment Considerations for 2019

With the excessive soil moisture and flooding that has occurred throughout South Dakota, growers may be thinking about using a fungicide seed treatment this planting season.

Sorghum Weed Control

Early competition, especially from grass, is critical for successfully controlling weeds in sorghum. There are preemergence as well as postemergence herbicides available for this crop. Early treatment provides the best control of broadleaved weeds with crop stage also being a critical factor for some postemergence treatments.

Plant Growth Regulator Reduces Height, Lodging in Oats

With the goal of reducing lodging in oats, SDSU Extension and a research team initiated a multi-location trial in 2018 growing season to study the effects of plant growth regulator (PGR) on oat performance.

Keep Your Hands Protected When Working With Insecticides!

One common misconception is that all chemical-resistant gloves provide the same amount of protection from insecticide products.

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.

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.
