Yield potential, pest resistance and seed price should be considered when selecting alfalfa varieties in Nebraska.
The most important variety decision for many farms and ranches is the selection of alfalfa. The choice of alfalfa variety affects production for three to 10 or more years, whereas varieties of annual crops can be changed every year.
Varieties that have been tested with commercial seed since 1991 for two or more years at locations in Nebraska and marketed in the state are shown in this 2001 extension circular revision.

Purple loosestrife is a noxious weed quickly invading Nebraska's wetlands. This publication describes the rearing and releasing of insects for biological control of the weed, as one part of an integrated management program. Purple loosestrife is a noxious perennial weed invading thousands of acres of wetlands and waterways in the Midwest. In Nebraska an estimated 18,000 acres are already infested by this plant, mostly along the main rivers and waterways. It has no natural enemies in North America, therefore it is very hard to prevent it from spreading. For years people have tried to eradicate it, especially in the Great …

Description of a rapid and efficient technique for detecting and assessing varroa mite infestations using powdered sugar to dislodge mites from bees.
The varroa mite was first discovered in the United States in 1987. Globally, it is the most important pest of honey bees and it has caused extensive losses in feral and managed colonies. Once introduced, varroa mites have never been eradicated from any country or region, and beekeepers must adopt an integrated pest management strategy to protect their colonies. Early detection and assessment of infestation levels are important components of a varroa management plan. Since varroa mites feed …
