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.

One of the many challenges producers face each year is weed control. Leafy spurge, in particular, can be difficult to manage.
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.
Tan spot and powdery mildew as well as barley yellow dwarf were found developing at low levels in winter wheat fields scouted the week of May 24, 2020.
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.
Winter wheat is starting to flower. It is important to monitor weather conditions from when wheat is heading until flowering to decide the need for fungicide application to manage Fusarium head blight.
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.
