Late Plant Crop Insurance Dates

Crop insurance late plant dates are fast approaching for planting small grains in South Dakota. Late plant dates for corn, soybean, and sunflower are nearing as well. Producers will want to work with their crop insurance agent to explore planting options and reporting of prevent plant areas.

Instinct HL and Nitrogen Management Effect on Winter Wheat Yield

Nitrogen (N) additives to control N losses through volatilization, denitrification, and leaching are widely used in the Midwest. Slowing the conversion of nitrogen fertilizers to nitrate may lessen leaching and denitrification losses if precipitation or soil becomes saturated.

Be on the Lookout for Black Grass Bugs

It’s time to begin scouting pasture and wheat for the presence of black grass bugs. Last year, we saw the highest populations in areas of Central and Southwestern South Dakota. If left untreated, black grass bug populations tend to increase year after year.

Wet Feet in Wheat

Given the widespread wet conditions present this spring, there are many areas in winter wheat fields with both ponding and saturated (or waterlogged) soils. Producers may want to consider soil conditions and evaluate extended weather forecasts when deciding whether or not to retain a winter wheat this spring.

Herbicide Considerations for Cover Crop Planting in 2019

Long residual pre-emergent or early post-emergent herbicides may cause stand reduction or complete failure of cover crops. Depending on efficacy of the herbicide, each situation can both affect in-season and/or post-harvest cover crop establishment.

South Dakota Herbicide Damage

As the spray season starts, it is always good to be aware of resources and testing facilities where you can send in possible herbicide-affected plant samples. SDSU Extension offers suggestions on how to handle possible herbicide damage situations as well as recommended labs that receive plant matter samples to test for herbicide residues.

July 2019 Climate Outlook: Challenges Continue

This year’s seasonal pattern of wetter than average conditions is projected to continue through July and the rest of the summer season. The latest climate outlook, released June 20, 2019, shows an increased chance of wetter than average conditions in the next one to three months for the state of South Dakota.

Soybean Production: Cost-effective pest management practices

Chemicals were one of the most expensive individual costs in soybean production, behind only to seed in the non-land cost category. The average cash-rent soybean production farms incurred a crop chemical cost of $39/ac in 2015, an 88% increase from 2010.
