This NebFact discusses the rhizomania virus in sugar beets.

G93-1158 Questions And Answers About Atrazine, Fred Roeth, S.D. Comfort

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide addresses some of the current concerns about atrazine and water quality. Included are some questions and answers about atrazine regarding toxicity, EPA guidelines, presence in water supplies, weed resistance and best management practices. What is atrazine? Atrazine is a herbicide that selectively controls broadleaf (dicot) weeds, such as pigweed, cocklebur, velvetleaf and certain grass weeds in fields of corn and sorghum. Selective control means that the target weeds are controlled, with little or no injury to the crop. Atrazine is well tolerated by actively growing corn and sorghum, which absorb and metabolize the herbicide and thereby detoxify it.

G93-1150 Rinsing Pesticide Containers, Larry D. Schulze, Clyde Ogg

University of Nebraska-Lincoln Extension: Historical Materials

It is estimated that every year one million plastic agricultural pesticide containers are used in Nebraska. Effective rinsing of these containers saves money, protects the environment and meets federal and state regulations on pesticide use.

Proper rinsing of pesticide containers is easy to do, saves money and helps protect people and the environment. It also helps prevent potential problems with unrinsed containers and storage of the rinse solution (rinsate). Even during a busy season, the few extra minutes it takes to properly rinse empty pesticide containers is time well spent.

G93-1157 Testing Irrigation Water, Delynn Hay, K.D. Frank

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains some of the reasons irrigation water should be tested and provides guidelines for collecting and submitting water samples. All irrigation water contains essential plant nutrients. These nutrients are free bonuses from a crop production standpoint. However, some nutrients can be present in amounts that will be toxic or damaging to crop growth. The nutrient content of Nebraska irrigation water can be highly variable from one location to another. The purpose of this guide is to provide guidelines for collecting and submitting irrigation water samples to laboratories for analysis. Reasons for having irrigation water tested are discussed. The …

G93-1171 Using A Chlorophyll Meter To Improve N Management, Todd A. Peterson, Tracy M. Blackmer, Dennis D. Francis, James S. Schepers

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to use a chlorophyll meter as a tool to improve nitrogen management by detecting nitrogen deficiency and determining the need for additional N fertilizer. Fertilizer nitrogen (N) is increasingly recognized as the source of nitrate contamination in much of Nebraska's groundwater. Improving the efficiency of fertilizer N use reduces the amount of N that can potentially contaminate water resources. Effective management of fertilizer N is a major challenge for grain crop producers. Many factors that affect its efficiency are beyond a producer's control. Weather, equipment limitations and breakdowns, and availability of labor and fertilizer during critical …

Nf93-140 Water Management For Irrigation In Nebraska, Norman L. Klocke, Joel E. Cahoon, Dean E. Eisenhauer, Delynn R. Hay, Glenn J. Hoffman, William L. Kranz, Derrel L. Martin, Darrell Watts, C. Dean Yonts

University of Nebraska-Lincoln Extension: Historical Materials

This NebFact discusses water management for irrigation.

G93-1183 Butterfly Gardening, Dale T. Lindgren, Stephen M. Spomer, Amy Greving

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide outlines planting schemes and arrangements that will help attract butterflies to a garden area.

Butterflies can be found in almost any part of Nebraska, from the Pine Ridge's coniferous forests and across the grasslands of the Sandhills to the deciduous forests along the Missouri River. Watching butterflies, much like bird watching or observing wildflowers has become a popular and enjoyable pastime. Since many natural butterfly habitats have been lost to urbanization and other development, some environmental organizations have incorporated butterfly conservation into their programs. Many people are taking a personal interest in attracting these fascinating insects to their …

G93-1180 Horn Fly Control On Cattle, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide identifies ways to control horn flies on cattle.

The horn fly is a blood-feeder that feeds 20 to 30 times per day. A population of several thousand horn flies may be present on one animal. When large numbers of these flies are on cattle, the cattle bunch and expend considerable effort fighting the flies. They will often stand in water or seek shade trying to get relief from the flies. When they do this, they fail to graze normally.

Studies in the United States and Canada show that during the grazing season yearling cattle free from horn flies …

G93-1153 Stable Fly Control On Cattle, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Control of stable flies in feedlots and dairy operations is covered here.

Description

The stable fly is about the size of a house fly but is dark gray and has dark irregular spots on its abdomen. The proboscis (mouthpart) protrudes bayonet-like in front of the head. The larvae are typical whitish fly maggots. The pupae are chestnut brown and about 1/4 inch long.

G93-1168 Moisture Testing Of Grain, Hay And Silage, Bruce Anderson, Rick Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide offers methods to help producers test moisture content of grain, hay, silage and other feeds.

Knowing the moisture and dry matter (DM) content of feeds is important to farmers for several reasons:

1. Livestock performance depends on DM consumed; thus, DM content must be known to accurately formulate rations.

2. Knowledge of moisture content is needed for harvest decisions during haying and silage chopping and for safe storage of grains, hay, and silage.

3. Moisture content is a major factor related to the value, or price, of forages and grain.

Every producer should be able to test for …

G93-1191 Glossary Of Water-Related Terms, William L. Kranz, Delynn Hay, James W. Goeke, David Gosselin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide is a glossary of water quantity, quality and human health related terms involving water. Terms are defined in contexts that could affect Nebraskans. We depend upon water for our very existence. The impact of water quality and quantity issues has never been greater. Yet the terminology used to describe the water we drink, the water we provide to plants and animals, the water stored underground, in lakes, rivers, and oceans, is not well understood by many Nebraskans. This listing of water-related terms is intended to reduce the potential for misunderstanding presentations made by elected officials, environmental agencies and …

G93-1133 Estimating Percent Residue Cover Using The Line-Transect Method, David P. Shelton, Roger Kanable, Paul J. Jasa

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to use the line-transect method to estimate the percentage of the soil surface covered with crop residue.

Crop residue left on the soil surface is one of the easiest and most cost-effective methods of reducing soil erosion. Research in Nebraska and other midwestern states has shown that leaving as little as 20 percent of the soil surface covered with crop residues can reduce soil erosion by one-half of what it would be from residue-free conditions. Greater amounts of residue cover will further reduce erosion.

G93-1181 Evaluating Your Landscape Irrigation System, Don Steinegger, Roch E. Gaussoin, Garald L. Horse

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide addresses irrigation techniques and methods that can improve water usage.

In the summer months, most water used in residential areas is applied to landscapes. By learning how much water to apply to your landscape and when to apply it, you simultaneously support four landscape irrigation goals: reducing costs, conserving water, reducing non-point pollution (contamination from a broad geographical area such as fertilizer, run off from urban landscapes), and maintaining an attractive landscape.
