The Fall Advantage of Kochia Control

Kochia is a problem in row crops in North Central South Dakota. New Post-emergent options in corn and soybean have helped alleviate Kochia competition from many fields, but these herbicide options shouldn’t be completely relied upon for a long-term plan for control.

Fall Noxious Weed Control

September 30, 2019

Fall is the time to control tough perennial broadleaf lawn weeds. Good moisture in most places in August will have set up good fall growth of perennial weeds.

Marestail Fall Control

No-till crop production in South Dakota is on the rise. Marestail is a native plant to the United States and is considered either a winter annual or biennial species that is often difficult to identify at the rosette stage. In the Dakota’s, the Marestail population will germinate in the fall and bolt in the spring.

Low Temperatures During Soybean Maturity

This year, we had a slow soybean planting due to high rainfall in spring. This was followed by below normal temperatures for most of the growing season, which delayed soybean growth and development. This brings up a question about what these low temperatures will do to soybeans that are in the field.

Fall Lawn Weed Control

October 02, 2019

Fall is the time to control tough perennial broadleaf lawn weeds. Good moisture in most places in August helped contribute to significant fall growth of perennial weeds.

Estimating Corn Yield in the Field

As a result of late planting and inconsistent weather, both in-field and across-field variations have been significant this year in South Dakota. Even on highly productive land, it is expected for corn yields to vary significantly. Estimating corn grain yield prior to harvest can help growers make management decisions, especially storage and marketing.

Weaning Calves on Cover Crops

What do we do if it is time to wean calves, but the pen isn’t ready? That can be a real concern during wet fall seasons, such as 2019. Putting calves into muddy pen conditions is far from desirable, but holding calves on the cows deep into fall increases the risk of adverse winter weather and tends to pull body condition off the cows.
