Herbicide Resistant Weeds, Alex R. Martin, Fred W. Roeth, Chad Lee Jan 2000

Herbicide Resistant Weeds, Alex R. Martin, Fred W. Roeth, Chad Lee

University of Nebraska-Lincoln Extension: Historical Materials

The development of herbicide resistant weeds is described along with strategies to prevent development. Herbicide resistance refers to plants within a weed species that, after repeated use of a herbicide, are no longer controlled by normal rates of that herbicide. Herbicide resistance often develops in fields that have been sprayed with herbicides with the same site of action for several years. Herbicide resistance is usually attributed to slight genetic differences between resistant and susceptible plants. These changes occur at a frequency of one plant in a million or even a billion. Herbicide resistance is not dependent on the environment or …


Nf422 Sunflower Head Moth Management, Ronald C. Seymour, Gary L. Hein, Ray Weed Jan 2000

Nf422 Sunflower Head Moth Management, Ronald C. Seymour, Gary L. Hein, Ray Weed

University of Nebraska-Lincoln Extension: Historical Materials

Sunflower head moth identification and biology, management, and chemical control.

Sunflower head moth, Homoeosoma electellum (Hulst), can cause substantial economic loss to commercial sunflowers in Nebraska and the surrounding region. Populations of sunflower head moth vary tremendously from year to year. Consequently, pest monitoring is important each growing season to determine when moths first appear and the extent of the infestation. Field scouting in confection sunflower fields is critical because of their higher value and the importance of maintaining quality.

Topics include sunflower head moth identification and biology, management, and chemical control.

G00-1404 Radon In Nebraska Homes: Healthy Indoor Air For Healtlhy Nebraskans (Revised October 2003), Rebecca L. Versch, Shirley Niemeyer Jan 2000

G00-1404 Radon In Nebraska Homes: Healthy Indoor Air For Healtlhy Nebraskans (Revised October 2003), Rebecca L. Versch, Shirley Niemeyer

University of Nebraska-Lincoln Extension: Historical Materials

Radon is a colorless, odorless, radioactive gas emitted from uranium, a naturally occurring mineral in rocks and soil. Normally, radon rises up through the soil and then dissipates in the air outside. Radon becomes a concern, however, when it seeps in through openings such as cracks, loose-fitting pipes, sump pits, dirt floors, slab joints, or block walls and accumulates in the home.

This publication will help householders understand radon — what it is, its effect on heatlh, how to test for it, and some remodeling or new building techniques that can reduce radon levels in the home.

G00-1395 Soybean Seeding Rates, Roger Wesley Elmore, James E. Specht Jan 2000

G00-1395 Soybean Seeding Rates, Roger Wesley Elmore, James E. Specht

University of Nebraska-Lincoln Extension: Historical Materials

The soybean stand looked horrible late that May. The field had a good seed bed at planting, but rain after planting crusted the soil over the seed furrows. Rain was in the short-term forecast. All other row crops were planted and looked fine, but this field concerned the producer. Should the producer replant? Recommended soybean seeding rates, stand assessment and replanting rates based on Nebraska field research are addressed in this NebGuide.


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 …

Ec00-1879 Sorghum Ergot In The Northern Great Plains, Jim Stack Jan 2000

Ec00-1879 Sorghum Ergot In The Northern Great Plains, Jim Stack

University of Nebraska-Lincoln Extension: Historical Materials

Sorghum is grown throughout Nebraska on approximately 0.6 million acres of land. It is grown as a forage crop as well as a grain crop. There is no significant commercial seed production in Nebraska. Grain sorghum is used domestically as livestock feed, in ethanol production, and to a limited extent as a food crop.

Grain sorghum is also exported to several countries. All sorghum hybrids (grain and forage) are susceptible to ergot disease. Ergot is a disease that impacts sorghum production directly by infecting unfertilized flowers and preventing seed development. Ergot also impacts sorghum production indirectly. Affected fields with honeydew-covered …

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.


Ec00-1564 A Guide To Identifying Nebraska Bumble Bee Species, Marion D. Ellis, Doug Golick Jan 2000

Ec00-1564 A Guide To Identifying Nebraska Bumble Bee Species, Marion D. Ellis, Doug Golick

University of Nebraska-Lincoln Extension: Historical Materials

For more people, pollen means allergies and bees mean stings. However, you should thank a bee, butterfly, bat, bird, or other pollinator for one out of every three bites of food you eat. There are 95 crops grown in the United States that require insect pollinators. In addition, many bee-pollinated plants provide food for wildlife, increase soil fertility, and beautify our landscapes.

This extension circular discusses the importance of bees, capturing bees, making a reference collection, identification guide, and glossary.

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how managers can tailor recognition to individuals, thus increasing its effectiveness.

The Importance of Rewards

If there's one thing in life that everyone wants it's to be appreciated, rewarded and recognized for their contributions. Studies indicate that employees find personal recognition more motivational than money. Results of a recent Council on Communication Management survey confirms this. According to a recent Gallup poll of people who stopped volunteering, 42 percent said they felt their work was unimportant or was unappreciated at the work place or in a volunteer setting, appropriately rewarding people is important to retention and job …
