Watch Temperature Forecast Before a Burndown Herbicide Application
As planting season approaches, no-till fields will likely need a burndown herbicide application to manage the established winter annual and early emerging summer annual weeds.
Early Preplant or Preemergence Applications for Weed Management in Corn: Which is better?
Preemergence herbicides should be a part of a successful weed management plan, as these applications limit the amount of early-season weed interference to limit yield loss and reduce selection pressure on herbicide-resistant weeds.
Herbicide Carryover and Planting Bare-Root Tree Seedling in New Windbreaks
Guidelines on herbicide carryover when planting bare-root tree seedlings in new windbreaks
2,4-D (Enlist One) and Glufosinate (Liberty) Additively Control Common Weeds in South Dakota Soybean Production
Fact sheet on the experiment to determine how 2,4-D and glufosinate, when applied alone or mixed, control common weeds and affect soybean yield.
Pasture Attacker: Woody Plants are Robbing Your Forage Production
Traditionally, the prairie is home to herbaceous vegetation, such as grasses and broadleaf plant species. Although many woody plants are naturally present in canyon, riparian, or river areas, they are not meant to be a part of the grassland landscape.
Removing Young Trees From Grasslands Will Save Money and Effort
Volunteer trees can hinder the development of desirable wildlife habitat and livestock resources. Early control of volunteer woody species is the simplest and most cost-effective option for maintaining open grassland habitats.
Understanding the Critical Role of Broadleaf Pollinator Plants in Pastures
Understanding the economic role of pollinators is the first step towards understanding their value to grassland and crop systems.
Use Caution When Fall Spraying Noxious Weeds in Pastures To Avoid Harming Desirable Plants
Noxious weed control is often a long-term process. In some cases, chemical application may be deemed necessary, but it should always be considered in the context of appropriate management and an integrated best management framework.
Dense Seeding Can Reduce Canada Thistle in Planted Grasslands
Canada thistle is a common invader in grassland plantings. Over the past decade, researchers and land managers have experimented with controlling Canada thistle in planted grasslands through increasing competition from desirable plants.
Poisonous Plants on Rangelands: Woody Species
Several woody plant species that are poisonous to livestock are found throughout South Dakota rangelands, including ponderosa pine, chokecherry, greasewood and broom snakeweed.
