Effects of Late Spring Frost on Alfalfa

Forage research indicates that, although alfalfa is considered to have good cold temperature tolerance, minor frost damage may occur when plants are exposed to air temperatures slightly below freezing for several hours, and more severe damage will be seen when temperatures drop below 25°F for four or more hours.

Low Temperature Effects on Winter Wheat

Low temperatures during the early morning hours of May 9–11, 2020 may have had detrimental effects on winter wheat in some areas of South Dakota. However, cooler spring temperatures that have slowed the winter wheat development this year may have actually been beneficial to S.D. producers, as later-maturing wheat is not as susceptible to injury from freezing temperatures.

Why Those Dandelions in Your Yard Aren’t So Bad

While research has shown that pollinators, specifically honey bees, can’t survive on dandelion pollen alone, this doesn’t mean that the dandelions aren’t still important for pollinators.

2020 Corn Growing Degree Days Update

Spring planting progress of corn in 2020 has been much ahead of a typical year in South Dakota. Crop development, however, seems slow.

Woody Weeds: Common Buckthorn

When considering weed control in tree plantings, the focus is generally placed on the control of herbaceous vegetation (grasses and forbs), particularly during the establishment phase. This focus is appropriate since control of herbaceous weeds is generally critical to establish a successful planting. As these plantings mature, providing perching sites for birds, another weed problem develops – the establishment of competing woody vegetation. These woody weeds are often left unchecked for many years because they look “natural” in a windbreak or other area of trees.

What's That Vine?

One of the most frequently asked questions that I have gotten recently refers to a vining plant that looks like it is going to take over the world, or at least a few trees in the yard or a section of a shelterbelt.
