Organic Garden Mulches To Conserve Moisture and Prevent Weeds

If you want to reduce time spent in your vegetable and flower gardens watering or pulling weeds, consider mulching the soil surface with an organic material to improve plant health and your enjoyment of the garden.

Options for Watering Home Gardens and Landscape Plantings

Ensuring that your garden plants receive adequate water throughout the growing season does not have to be overwhelming. There are a variety of water management options available to make the process easier.

Wireworms in the Garden

With warming soil temperatures, overwintering wireworms have become active throughout South Dakota. Wireworms are soil-dwelling insects that can be pests of germinating seeds, seedlings and root crops.

Seedcorn Maggot Degree Day Activity Estimates: May 20, 2021

Seedcorn maggots can be an early-season pest of corn and soybean in South Dakota, typically affecting crops that are emerging or have recently emerged. Seedcorn maggots can cause direct loss by destroying planted seeds.

Alfalfa Weevil Activity Prediction Update: May 20, 2021

This week we accumulated degree days for alfalfa weevils at a rapid rate. As a result, we observed many areas of the state potentially move through more than one larval life stage.

Common Stalk Borer Activity Estimate: May 13, 2021

The upcoming weather forecast looks warmer than the last few weeks, and that means we will begin to accumulate degree days for the common stalk borer at an increased rate.

As temperatures continue to warm up, degree days are beginning to accumulate a little faster for common stalk borers. Most of South Dakota is still between conditions approaching egg hatch and egg hatch occurring.

Common Stalk Borer Activity Estimate: April 22, 2021

In its early vegetative growth stages, corn is susceptible to feeding by the common stalk borer. The hatching and movement of common stalk borer caterpillars can be estimated by using degree days.

Warmer weather is finally here. Although we have accumulated quite a few degree days for common stalk borers, nowhere in the state has reached accumulation levels for common stalk borer caterpillar movement into corn fields.
