South Dakota Pest Management Guides
The South Dakota Pest Management guides are now available for free. The guides offer recommendations for controlling weeds, insects, and diseases in a variety of South Dakota crops.

Crops
During the growing season, SDSU Extension provides weekly production recommendations.
Corn
Nearly one out of every three dollars generated by South Dakota agriculture starts in a corn field. Two of every three rows of corn become ethanol.
Effects of Spring Flooding on Weed Seed Movement
How does spring flooding impact weed seed movement and dispersal? The flooding that is occurring from spring snow melt may cause weed seeds that are on the soil surface or eroded soil to move, and possibly long distances.
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.
Herbicide Rotation Restrictions
This is a quick reference guide to common herbicides and their rotation restrictions for selected crops.
Timely Control of Kochia
Warm temperatures across South Dakota could allow Kochia to get a head start this spring. Kochia control, like all weed control, takes proactive farm management to prevent weed establishment from occurring, rather than reacting to the latest problem.
Herbicide Residual Effects on Cover Crops After Corn Silage
As cover crop usage has increased in recent years, managing weeds through a longer residual herbicide program has become more complicated. Learn some considerations for cover crops following corn silage.
Weed Control in Sweet Corn
When growing sweet corn on a large scale, weed control can be challenging, and certain steps need to be taken before choosing an herbicide.
Crop Tolerance to Soil Herbicide Residual
Some herbicides can persist in soil, especially dry soil. Herbicide carryover could be an issue in 2021 across the state depending upon last year’s moisture levels and field conditions.
