What’s Killing My Zucchini and Squash Plants?

For many of us, this time of year is tough for our zucchini, squash and pumpkin plants.

When pushed, the plants typically break and reveal clear evidence of insect feeding through the stem.

Alfalfa Weevil Activity Prediction Update: April 14, 2020

The alfalfa weevil is a major spring insect pest of South Dakota alfalfa. Before 2018, this insect was reported as having large populations throughout much of South Dakota. However, during 2018 and 2019, we received fewer reports of alfalfa weevils, which may have been a result of the cooler and wetter spring conditions that were observed.

Alfalfa Weevil Activity Prediction Update: April 20, 2020

During the last week, the colder weather that we experienced across South Dakota resulted in very little degree day accumulation. However, in some areas enough degree days have accumulated to potentially lead to adult activity within alfalfa fields.
