Nf00-411 Seed Treatment Fungicides For Soybeans (Revised January 2004), Loren J. Giesler Jan 2000

Nf00-411 Seed Treatment Fungicides For Soybeans (Revised January 2004), Loren J. Giesler

University of Nebraska-Lincoln Extension: Historical Materials

The most common soybean disease problem in Nebraska is seedling damping off and seed rot caused by several fungi. Early season damping off and root rots are often followed by premature death, which in many instances may be attributed to fungal infections earlier in the season.

This NebFact discusses the seed treatment fungicides for soybeans. These includes protectants (contacts) that are effective only on the seed surface; and systemic fungicides that are absorbed by the emerging seedling, which inhibit or kill the fungus inside host plant tissues.


G00-1412 Daylilies (Revised March 2003), Anne Streich, Don Steinegger Jan 2000

G00-1412 Daylilies (Revised March 2003), Anne Streich, Don Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

Daylilies (Hemerocallis sp.) are a common sight in many of today's landscapes. They are easy to grow, have few insect and disease problems and are available in many colors. In addition, they tolerate heat, drought, salt, compacted soil and various pH's. A daylily is available for almost any landscape condition and are discussed in this NebGuide.


G00-1393 Grazing Alfalfa (Revised September 2004), Jerry D. Volesky, Bruce E. Anderson Jan 2000

G00-1393 Grazing Alfalfa (Revised September 2004), Jerry D. Volesky, Bruce E. Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Alfalfa is the most productive and versatile forage legume grown in Nebraska. Cutting for hay or silage has been the traditional method of harvest, but many options also exist for grazing. With current technology and proper management beef gain can exceed 1,000 pounds per acre with acceptable stand persistence.

Grazing alfalfa may be a cost efficient means of harvest for some producers. This NebGuide explores alfalfa and alfalfa/grass options, varieties and stand establishment, and grazing and bloat management.


Nf00-429 Controlling Pond Algae With Barley Straw, John C. Holz Jan 2000

Nf00-429 Controlling Pond Algae With Barley Straw, John C. Holz

University of Nebraska-Lincoln Extension: Historical Materials

Algae are microscopic, free-floating plants which comprise a critical component of a lake's food web. They are fed upon by tiny animals called zooplankton which are an important food source for fish. Algae color the water green or brown, and uncontrolled growth can lead to nuisance surface scums, poor water clarity, noxious odors and an overall reduction in the lake's recreational value. Excessive levels or "blooms" of algae occur when nutrients, especially phosphorus, are abundant. After taking steps to reduce the amount of phosphorus entering a lake, it may be desirable to control the algae growth directly. Typically this is …


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 Jan 2000

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.


Ec00-1759 Nebraska Register Of Champion Trees 2000, Scott J. Josiah Jan 2000

Ec00-1759 Nebraska Register Of Champion Trees 2000, Scott J. Josiah

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska is famous for its sports champions, but how about Champion Trees? While Nebraska is considered a "prairie state," trees have always played a prominent role in the quality of life of Nebraskans. Native trees were used to build the first pioneer homes. They also were used to heat them and protect them from wind.

The Nebraska Champion Tree program identifies and recognizes the largest living specimen of all native and the most common introduced tree species in Nebraska.


G00-1417 Site Preparation: Key To Successful Conservation Tree Planting In Western Nebraska (Revised February 2002), Doak Nickerson Jan 2000

G00-1417 Site Preparation: Key To Successful Conservation Tree Planting In Western Nebraska (Revised February 2002), Doak Nickerson

University of Nebraska-Lincoln Extension: Historical Materials

Establishing a conservation tree planting can be a challenge in semiarid regions like western Nebraska, where annual precipitation of 20 inches or less is the norm. Tree planting failure commonly occurs as a result of poor site preparation coupled with inadequate weed and grass control the first three to five years after planting. Effective site preparation begins the year before planting. The results help young trees survive and grow in several ways. This NebGuide explains when and how to do site preparation for conservation tree planting in Western Nebraska.


Nf00-410 Fungicide Options For Managing Foliar Diseases On Wheat, John E. Watkins Jan 2000

Nf00-410 Fungicide Options For Managing Foliar Diseases On Wheat, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Stripe and leaf rusts, tan spot and Septoria leaf blotch comprise the four primary foliar diseases of wheat in the central Great Plains. In eastern and south central Nebraska leaf rust and Septoria leaf blotch are common, and in the wheat-fallow-wheat regions of western Nebraska, tan spot is an important foliar disease. Stripe rust occurs statewide.

This NebFact discusses the options of treatment criteria, profitability of treatment, treatment products and timing for managing foliar diseases of wheat.
