Know Soybean Cyst Nematode, Numbers Matter!
Have you noticed parts of your soybean field turning yellow earlier than expected? Are some of the plants stunted or showcasing a roller coaster appearance? Soybean cyst nematode may be to blame.
Redheaded Flea Beetles Are Active in South Dakota
Redheaded flea beetles are now active in soybean. Although they haven’t caused significant defoliation yet, their activity should be monitored, as other defoliating insects are also present in soybean.
Soybean Aphids Active in South Dakota
Soybean aphid populations have been observed in South Dakota. Although populations are still very small and not widely dispersed, it is a good reminder that soybean aphid scouting should occur throughout the growing season.
Soybean Gall Midge Larvae Detected in South Dakota Soybean
Soybean gall midge larvae have been detected in southeastern South Dakota. Although the infestations probably won’t result in plant death in many fields in 2022, the infestations could be a source for soybean gall midge adults in 2023.
Bean Leaf Beetles Showing Up in Soybean
We have been observing an increasing number of bean leaf beetles active in soybean during the last week. See our latest observations and management recommendations.
Soybean Gall Midge Adults Detected in South Dakota
Soybean gall midge emergence was first detected in South Dakota two weeks ago, during the week of June 13 -17, 2022. Emergence continues to be slow, with the only observations in southeast South Dakota.
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.
Tiger Beetles: Beneficial Predators and Ecosystem Health Indicators
Tiger beetles are generalist predators, meaning they prey on a wide variety of pests. Observing them in a landscape is a great sign that an ecosystem is healthy and supporting a diversity of both prey and predators.
