Pre-Plant Disease Management Considerations
If the forecast holds true, it looks like it is going to be another year of excessive soil moisture and possible flooding come this spring. The increased level of soil moisture has implications with regards to plant stand establishment as well as root rot and nematode infestations.
Current Weather Conditions Are Conducive White Mold Development in Soybeans
Frequent rains and overcast conditions continue to occur in South Dakota’s main soybean growing counties. These conditions favor white mold development. In some of these counties, soybean is already at R1, which is also the best timing for fungicide application targeting white mold control.
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.
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).
SDSU Extension to Host Winter Agronomy Road Show
January 14, 2022
SDSU Extension will offer in-person agronomy clinics this winter at four different locations across the state. Kicking off Jan. 28 in Aberdeen, each location will have content that is customized to growers and agribusiness professionals in that area.
Forecasted Cold Temperatures Can Be Used To Cool Down Stored Grain
If temperatures are forecasted as being well below freezing, it would probably be a good time to start thinking about cooling stored grain. Cooling grain reduces the activity of stored grain insect pests and suppresses any mold growth that may otherwise occur.
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?
Using Weather Forecasts for Extreme Cold Risk to Newborn Livestock
Calving and lambing during a winter season with extreme weather swings can be concerning when caring for newborn livestock. The Cold Advisory for Newborn Livestock (CANL) forecast can be a useful tool for producers when preparing for newborn animals.
