Use the Scab and Leaf Disease Forecasting Tools to Decide on Fungicide Application in Wheat

Fungicide application in winter wheat has consistently shown to prevent yield loss caused by fungal diseases. However, in some cases, a fungicide application may not always result in a profitable yield when disease pressure is low. Disease forecasting tools can aid fungicide application decisions and hence improve on the profitability of fungicide application.

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.

Implications of Excessive Soil Moisture for Disease Development in Winter Wheat

Although it is too early to start thinking about disease issues in winter wheat at this time, current flooding in some areas may have implications on diseases that may develop on winter wheat.

Seeing Dead Soybean Plants in a Circular Pattern? Could Be Due to Lightning

While quite uncommon for lightning to damage row crops, it does happen. Thunderstorms can have lightning that can burn soybeans plants leading to their death.

Winter Wheat Breaking Dormancy Early

A threshold indicator for winter wheat emergence is to consider average temperatures over a 14-day period. When that 14-day average temperature is equal to or above 5°C, or 41°F, then hard red winter wheat can break dormancy.

The Small Grains Disease Forecasting System Could Save Producers Money

The South Dakota State University Small Grains Plant Pathology program has partnered with the Small Grains Plant Pathology program at North Dakota State University to deploy a small grains disease forecasting system for South Dakota. The system uses weather variables including rainfall, temperature, and relative humidity to predict the likelihood of disease development. This new tool has the potential to save growers money by helping them avoid unnecessary fungicide applications, or knowing when to apply a rescue fungicide treatment.

Updated National Fusarium Head Blight (Scab) Prediction Center

The new Fusarium (Scab) Head Blight Prediction Center is now up and running. The purpose of this Assessment Tool is to provide producers and crop consultants with a Fusarium Head Blight (FHB/scab) risk assessment tool which leads up to and includes flowering (anthesis).

La Niña Expected to Influence 2021-22 Winter Climate

November 23, 2021

La Niña conditions have been officially declared this season by the National Oceanic and Atmospheric Administration (NOAA), but what does that mean for South Dakota’s winter climate, and this year’s outlook in particular?

Newborn Lamb Care Management

Proper newborn lamb care is a critical component of flock profitability. In the U.S. lamb mortality from all causes is approximately 20% with more than 80% of those losses occurring in the first two-weeks following lambing.

Minimizing Hay Storage Loss From Heating or Fires

Successful hay storage is essential to preserving high quality forage, while ensuring desired performance from livestock and deterring economic losses from unwanted hay storage fires.
