Soybean Aphids Active in South Dakota
Soybean aphid populations have been observed in South Dakota. Although populations are still very small and not widely dispersed, it is a good reminder that soybean aphid scouting should occur throughout the growing season.
Wheat Streak Mosaic Virus Showing Up in Fields
Wheat streak mosaic virus is a viral disease, which has been found in samples recently sent into the SDSU Plant Diagnostic Clinic. Learn how to identify it before it takes a toll on wheat crops.
Preparing Spray Solutions: Mixing Order
Before mixing any pesticide always check the pesticide label for instructions on compatibility of two or more pesticides. Some herbicides and carriers require a compatibility agent, some are not compatible with a compatibility agent.
Best Management Practices for Sunflower Production
This is your unbiased, research-based guide to sunflower production, providing the latest recommendations to help increase yield, reduce input costs and protect your investment.
Monitor Soybean for Bean Leaf Beetle Activity
Some of the bean leaf beetles we are currently observing in South Dakota may make up the population of overwintering adults. While these adults are in soybean, they can cause significant amounts of defoliation to the leaves.
What Is Causing Soybeans to Yellow at This Time?
Recently scouted soybean fields were observed with yellowing plants, and one field was found to have plants dying prematurely. Learn some of the factors that may cause soybean plants to yellow at this time in the growing season.
Drought Conditions May Increase Soybean Cyst Nematode Population in Soil
Moisture stress coupled with above-normal temperatures have been linked with increased soybean cyst nematode populations in the soil. In order to keep populations in the soil below the yield-reducing levels, there are a few management practices which can be used.
Differentiating Between Wheat Head Diseases and Disorders
Several diseases and disorders can develop in wheat heads. Learn the symptoms of several common disease and insect issues being observed in South Dakota wheat this growing season.
Cover Crop Considerations When Dealing With Soybean Cyst Nematode
With the soybeans being harvested a little earlier than usual this year, some producers are finding themselves making management decisions that include cover crops. For soybean producers dealing with soybean cyst nematode in their fields, selection of cover crops is important since some of these can be hosts for soybean cyst nematode.
Soybean Cyst Nematode Management Plans Should Include Proactive Weed Management
While soybean cyst nematode can be managed through use of resistant varieties and crop rotation, presence of alternative weed hosts can negate the benefits of these practices by providing a host for soybean cyst nematode to continue to accumulate in the soil.
