Ec00-153 Selecting Alfalfa Varieties For Nebraska, Bruce Anderson, Michael Trammell, Patrick E. Reece

University of Nebraska-Lincoln Extension: Historical Materials

Yield potential, pest resistance and seed price should be considered when selecting alfalfa varieties in Nebraska.

The most important variety decision on 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 change every year.

This extension circular lists the alfalfa varieties that have been tested in Nebraska with commercial seed for two or more years since 1997 and marketed in the state. These are the 2000 results.

Nf00-425 Resistance Management For European Corn Borer And Bt Transgenic Corn: Refuge Design And Placement (Revised October 2002), Thomas E. Hunt, G.W. Echtenkamp

University of Nebraska-Lincoln Extension: Historical Materials

One of the key issues surrounding the use of Bt transgenic corn hybrids is resistance management. These corn hybrids have been engineered to produce a version of the insecticidal protein from the naturally occurring soil bacterium, Bacillus thuringiensis (Bt), that is toxic to European corn borers and a few other insects.

This NebFact discusses the important principles of resistance management for European corn borer and Bt corn and refuge considerations.
