South Dakota Overwintering Bean Leaf Beetle Predicted Mortality: 2021-2022

Bean leaf beetle emergence is approaching, so it’s important to start thinking about this pest. Knowing the number of days that the air was cold enough for bean leaf beetle mortality allows us to estimate the emerging populations in the spring.

South Dakota Overwintering Bean Leaf Beetle Predicted Mortality: 2023-2024

Every year we evaluate the overwintering success of bean leaf beetles in South Dakota. At emergence, the overwintering population of bean leaf beetle adults will move into soybean fields and begin feeding on the seedlings.

South Dakota Overwintering Bean Leaf Beetle Predicted Mortality: 2024-2025

Each year we evaluate the overwintering success of bean leaf beetles in South Dakota. For adult bean leaf beetles that successfully overwintered, emergence will begin in the spring and they will move into soybean fields.

Grasshopper Activity Is Ramping Up

We have already observed increased grasshopper activity in many areas of the state and, depending on the 2022 season, they may become problematic in crops.

Double-Crop after Wheat?

Two crops in one year may sound tempting, and for some crop species is possible, but before doing so, producers should consider possible crops and compare the potential benefits with the drawbacks.

Wind and Rain May Have Delayed Preemergence Herbicide Application: What Now?

With recent winds and rain, preemergence herbicide applications may be further delayed. Scouting to determine if crops and/or weeds have emerged is critical to ensure effective and safe application of preemergence herbicides.

Spotted Wing Fruit Fly Damaging Fruit Crops

The spotted wing fruit fly is a new pest problem that originated in Asia and was only first identified here in the United States in California in 2008. It was first seen in South Dakota in 2013.

Harvesting For Maximum Soybean Yields

Numerous studies have been conducted over the last 40 years on soybean combine losses which show that yield loss can be as high as 15 percent.

Understanding Contract Language and Restoring Native Grassland Damage after Energy Development

Energy development on private lands can result in locally heavy land manipulation. Of particular concern is the manipulation of native grasslands and other sensitive areas and how it will affect those areas in the short-and-long-term.

South Dakota Overwintering Bean Leaf Beetle Predicted Mortality: 2022-2023

With bean leaf beetle emergence rapidly approaching, it’s important to start thinking about early-season management of the overwintering population. View our latest recommendations based on observations from winter 2022-2023.
