For most of us, wheat is wheat. However, there is a distinct difference between spring and winter wheat, even though the vegetative characteristics of these two wheat types are very similar.

With many flooded and saturated fields in South Dakota this fall, harvesting silage before corn dries past desired moisture levels or frost occurs may be a challenge for some producers.
The chances of a wet October increased with the latest climate outlook update, released on September 30, 2019. In the first few days of the month, rain or snow has scattered across much of the state. There hasn’t been a heavy rain or snow event this month. The outlook shows odds leaning towards much of the same pattern in the weeks ahead.
Corn marketed at the standard moisture content of 15.5% and 56 pounds per bushel typically contains 47.3 pounds of dry matter and 8.7 pounds of water. At harvest, a producer has to decide whether to sell (or even store) his corn at ‘as is’ moisture content or mechanically dry it before taking it to the buyer.
Several corn fields are beginning to show stalk rot and top dieback symptoms. Stalk rots cause the entire plant to die prematurely, which can lead to plants lodging under windy conditions making harvesting problematic.
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.
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.
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.
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 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.
