Degree day accumulations continue to approach the peak emergence of the second generation of seedcorn maggots. See our latest management recommendations based on this activity.
For most of South Dakota, peak emergence of the overwintering seedcorn maggot population has passed. See our latest activity estimates for the second generation.
Warmer weather during the last week resulted in fast accumulation of degree days throughout South Dakota. See how it impacted activity estimates for the common stalk border.
For agroecosystems and gardens struggling with weeds and insect pests, ground beetles can be a beneficial predator. Learn the benefits they can bring to your landscape this growing season.
