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.
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.
Fungicide Resistance: Risk and Management
What is fungicide resistance?
Fungicide resistance can be defined as when a pathogen population is no longer sensitive or has reduced sensitivity to the fungicide that used to control the same pathogen.
Utilize a Fungicide For Crown Rust Prevention in Oats
If you are growing oats this year for grain, be sure to scout and plan a fungicide application to protect the oats from crown rust.
Determining an Economically Optimal Nitrogen Rate for Corn in 2022
While we can't know what the prices of corn and nitrogen fertilizer will be next year, it is very important to understand how the level of both prices will influence corn profitability for 2022.
Fall Soil Sampling
With fertilizer prices on the rise, it’s more important than ever to understand your soil test levels and crop response to applied fertilizers. Fall is a great time to soil sample before freeze up.
Powdery Mildew: A Disease Concern in Field Peas
Producers of field peas may need to scout for powdery mildew this year. Powdery mildew is a late-season fungal disease that can impact peas if weather conditions are conducive. However, this disease can also occur in early planted fields in South Dakota under the right environmental conditions and when the crop canopy is heavy.
Monitor Canola Fields for False Chinch Bug Activity
While scouting canola this week, I came across a field that had plants along the edge that looked like they were suffering from drought stress, but given the recent rain I doubted that to be the case. Closer inspection of the stressed plants indicated that they were covered in false chinch bugs. Although false chinch bugs are not normally an issue in canola, very large populations do have the potential to reduce yield.
It’s Time to Start Scouting for Red Sunflower Seed Weevils
In South Dakota, sunflower flowering is getting underway. That means it is time to start scouting fields for red sunflower seed weevils.
False Chinch Bugs Are Active in Canola
We have received reports of false chinch bug populations in canola this week. Heavily infested canola fields will sometimes appear drought stressed, but closer inspection reveals that false chinch bugs are the culprits for the wilting plants.
