Early Season Insecticide Applications in Wheat
Many wheat producers in South Dakota have adopted more intensive management practices in the last few years, including an early season application of fungicide and, in some cases, insecticide.
Herd Inventory Centers on Feed Available
With drought conditions continuing across the state, livestock producers will be making hard decisions on livestock inventory numbers as pasture and feed availability become an even more significant factor.
New Multi-State Extension Publication: Managing Insecticide-Resistant Soybean Aphids
The first pyrethroid resistant soybean aphids were reported in Minnesota in 2015. Since then, pyrethroid resistant soybean aphids have been reported in Iowa, North Dakota, and South Dakota. In an effort to address resistance, researchers from those states have put together a new extension publication.
Overwintering S.D. Bean Leaf Beetles: 2017 predicted mortality
The overwintering generation of bean leaf beetle adults emerge in the spring and can cause serious defoliation injury to seedling soybean plants. However, the abundance of overwintering bean leaf beetles is negatively affected when the air temperatures get too cold. Therefore, an estimate of the emerging populations can be made based on how cold the winter was.
Soybean Pests: Bean Leaf Beetles and Bean Pod Mottle Virus
With the number of bean leaf beetle observations in soybean fields during 2016, the need for monitoring soybean for Bean pod mottle virus (BPMV) development increases. Bean pod mottle virus was first identified in South Dakota in 1998, and is recognized as a very economically important disease in soybean due to the potential for it to cause devastating losses to soybean yields.
Small red maggots under your soybean plants’ epidermis? We have answers.
In 2015, we received plant samples of soybean that had small red maggots under the epidermis. Now, in 2017, we are starting to receive reports of these same insects being found under the epidermis of soybean in different parts of South Dakota.
Crop Hour
SDSU Extension will deliver a series of virtual Crop Hour webinars starting January 9 through March 7, 2024, every Tuesday, Wednesday and Thursday from 10:00 a.m.-11:00 a.m. CST.
Fall is a Good Time to Test Your Soil for SCN
Is your yield monitor indicating low yielding areas in your soybean field? Soybean Cyst Nematode (SCN) could be the problem. Get to the root of the problem by testing your soil for the soybean cyst nematode. SCN management starts with a soil test to determine the presence or absence of this nematode in the soil. Absence may indicate either the SCN has not established in the field or could be present in non-detectable levels.
Ready, Set, Manage Hay Differently
Feed is expensive and sometimes hard to find. Pasture prices, harvest expenses, hauling and waste add to the total feed bill. Evaluate your forage situation this winter and make changes that improve your profitability.
