G90-1007 Pesticide Management And Safety On Home Grounds, John C. Fech, Larry D. Schulze

University of Nebraska-Lincoln Extension: Historical Materials

Pesticides can be valuable tools in controlling lawn and garden pests. They must be used according to the label, with regard for the safety of people and animals.

Pest infestations often develop in lawns or gardens, damage lawns and ornamentals, and reduce the attractiveness of the home setting. When an infestation occurs, gardeners can reach a decision in pest management by answering the following questions: What is the pest? Is the pest causing unacceptable damage? Are controls needed? What pest control method(s) should be used?

There are several methods of pest control. The main methods of pest control and some …

G90-1001 Spray Drift Of Pesticides, Larry D. Schulze, Robert Grisso, Robert Stougaard

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses conditions that cause particle drift, and methods private and commercial applicators may employ to reduce drift potential from pesticide spray applications.

Spray drift of pesticides away from the target is an important and costly problem facing both commercial and private applicators. Drift causes many problems including:

1. damage to susceptible off target sites,

2. a lower rate than intended which can reduce the effectiveness of the pesticide, wasting pesticide and money, and

3. environmental contamination, such as water pollution and illegal pesticide residues.

Drift occurs by two methods; vapor drift and particle drift. This NebGuide focuses mainly …

G90-990 Explosion Venting And Suppression Of Bucket Elevator Legs, David D. Jones

University of Nebraska-Lincoln Extension: Historical Materials

Explosion vents and explosion suppression devices limit the danger and damage associated with grain dust explosions. This NebGuide discusses these devices and design guidelines for application on bucket elevator legs.

The bucket elevator leg has been identified as a major source of grain dust explosions. As a bucket elevator leg conveys grain, the elements necessary for a grain dust explosion are possible. Fuel (grain dust in suspension above the minimum explosive concentration), oxygen and confinement are inherent inside a functioning bucket elevator leg. Introduction of an ignition source will initiate a grain dust explosion.

A Dss For Farm Management, Y Kashi Vishwanadhan

IIMB Management Review

Farm management is a decision process. The tarmer and the state as
decision makers at different operational levels have some what conflicting
objectives to achieve-the farmer has to choose between alternative use of
scarce resources - land, labour and capital and operate his farm to maximize
the net returns; whereas the state has to increase the agriculture production to
meet the demand of the population even at higher levels of input costs. It has to
take decisions relating to Support Prices for various crop products, credit and
input supply in such a manner as to ensure healthy progress in the …

G89-901 Understand Your Soil Test: Sulfur, K.D. Frank, Delno Knudsen

University of Nebraska-Lincoln Extension: Historical Materials

Factors leading to sulfur deficiency, soil and water tests, soil test interpretation and fertilizer materials that contain sulfur are covered here.

Sulfur, one of the macro-nutrients, may be deficient in some sandy soils but usually is plentiful in other soils of the state. The amounts contained by healthy crops are on the same order as phosphorus, ranging from 0.2 percent to .5 percent sulfur. It is a component of certain amino acids, and so is part of several proteins essential for plants and animals.

G89-912 Alfalfa Crown And Root Rots And Stand Longevity, John E. Watkins, Fred A. Gray, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Causes of crown and upper root rot, symptoms and management are discussed here.

Alfalfa (Medicago sativa L.) is the most important forage crop species in North America. It is widely adapted, energy efficient, and produces the most protein yield per acre. Alfalfa is well-suited to both dryland and irrigationd soils of Nebraska.

Many factors contribute to the decline in productivity of an alfalfa stand. Under favorable growing conditions and proper management, alfalfa stands in Nebraska can last over 10 years.

G89-932 Minimum Center Pivot Design Capacities In Nebraska, William L. Kranz, Derrel L. Martin, Greg Lackas

University of Nebraska-Lincoln Extension: Historical Materials

Factors to consider in choosing an appropriate center pivot design are covered here. Irrigators investing in a center pivot irrigation system need to consider this important question: How much supplemental water is required by the crop? Irrigation system capacity needed to meet crop requirements is defined in units of gallons per minute (GPM) or gallons per minute per acre (GPM/AC). If the system capacity is too low, crop stress occurs during some portion of the growing season. If the capacity is too high, surface runoff may result, or capital investment for the pumping plant and center pivot may be greater …

Assuring A Long Term Groundwater Supply: Issues, Goals And Tools, Richard C. Peralta

All Archived Publications

Groundwater is a hidden, but important resource. We can practicably define groundwater as water be· neath the ground surface that can be extracted by wells. Other water in the ground that is not considered to be available for man's direct use is commonly called "subsurface water." Subsurface water includes moisture within the root zone.

G89-937 The Pesticide Label, Larry D. Schulze, Shripat T. Kamble

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the parts of a pesticide label to aid understanding and promote safe and effective use of pesticide products.

Pesticide information can be provided to end users through labels and labeling. Not all pesticide products have labeling. While the words are similar, they have distinctly different meanings.

G89-900 Phytophthora Root Rot Of Alfalfa, John E. Watkins, Fred A. Gray, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Disease cycle, symptoms and management practices for phytophthora root rot are discussed in this NebGuide.

Phytophthora root rot (PRR) is a major cause of seedling death in newly established alfalfa, and causes a progressive decline of established stands in Nebraska. This disease is caused by the fungus Phytophthora megasperma f. sp. medicaginis and occurs in most of the alfalfa producing areas in North America.

The Phytophthora that infects alfalfa is different from the Phytophthora that causes root rot in soybeans. Growers sometimes think the two diseases are the same for the respective crops, but they are two different diseases with …

G89-931 Alfalfa Anthracnose, John E. Watkins, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Symptoms, disease cycle and control of alfalfa anthracnose are discussed here.

Forage crops are grown on and harvested from more acres in Nebraska than any other crop. Of the almost 49 million acres of agricultural land in Nebraska, approximately 24 million acres are in hay. Alfalfa production has stabilized at about two million acres.

High feed and forage production costs and periodic droughts have generated increased concern by farmers and ranchers over forage losses from diseases, insects and environmental stresses. Estimates suggest about one-fourth of the U.S. alfalfa hay crop and one-tenth of the seed crop are lost annually to …

G88-892 Mixing Quality Pig Feed (Revised July 1992), Duane Reese, Mike Brumm

University of Nebraska-Lincoln Extension: Historical Materials

Pig feed quality problems and mixing recommendations are covered here. Feed ingredients represent over 60 percent of the total cost of farrow-finish pork production and 65-70 percent of the variable expenses. Attention to quality preparation, in addition to purchasing decisions, is a component of feed ingredient cost management. Errors in formulation, misuse of feed mixing equipment, use of poor quality feed ingredients or lack of a quality assurance program can have costly consequences.

G88-874 Management Tips For Round Bale Hay Harvesting, Moving, And Storage, John A. Smith, Robert D. Grisso, Kenneth Von Bargen, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses management of hay harvesting with a large round baler. Specific management practices are necessary to maintain hay quality and minimize hay loss during harvest, transportation and storage of large round bales.

Large round bale packaging systems allow one person to harvest, store and feed large quantities of hay for small as well as large acreages. Good management is required to maximize effectiveness. Losses in baling, transportation and storage of large round bales can far exceed the losses of rectangular bales unless the large round bale system is properly managed.

G88-875 Weed Control In Soybeans, Russell S. Moomaw, Robert N. Stougaard, Alex Martin, Fred Roeth, David Mortensen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides information on mechanical and chemical weed control methods, including herbicides to use for preplant incorporated, preemergence and postemergence. Soybeans are a relatively easy crop to grow. Limited insect and disease problems presently are associated with their production in Nebraska. Weeds, however, are a major production problem. Each 100 pounds of weed growth results in a one bushel loss in soybean yield. Weeds that emerge with the crop and remain in the row are the strongest competitors. Those that emerge later than six weeks after planting have little effect on yield, so it is important to focus on …

G88-864 Handling Internal Worm Parasitism In Sheep, Dale M. Grotelueschen, Don Ferguson, Ted Doane

University of Nebraska-Lincoln Extension: Historical Materials

This publication acquaints the reader with methods of preventing, controlling, and treating parasitism in sheep.

Introduction

Parasites or worms affecting the digestive system are a severe health problem in sheep production. The economic losses from parasitism can be extensive, ranging from mortality or death loss to weight loss, reduced weight gain, reduced wool production, decreased milk yield resulting in lower lamb weights, poor reproductive performance, and the cost of medications and handling.

Coccidiosis, another costly intestinal parasite, but not caused by worm infestation, will be discussed briefly.

G88-883 Managing Of Disease To Produce Antibiotic/Residue Free Animal Food Products, Duane Rice, R. Gene White

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the use of antibiotics in animals, approved drugs and extra-label drugs, and ways to test for drug residue. Infectious diseases in livestock are costly, and prevention is the best approach to minimize such losses. Yet despite good management practices and extensive preventive measures, disease outbreaks do occur, and treatments become necessary. To obtain antibiotic residue-free products from food animals, knowledgeable decisions regarding the use of medications are necessary. It is important to realize that antibiotic treatments are used only to eliminate or shorten the duration of existing infections, or to prevent secondary bacterial infections. These infections may …

Commodity-Specific Effective Exchange Rates For U.S. Agriculture, Emilio Pagoulatos, Azzeddine Azzam

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A number of commodity-specific effective exchange rates of relevance to U.S. agriculture have been constructed. It is hoped that data presented in this study will be of use to researchers investigating the interrelationships between the dollar exchange rate and agricultural trade. An examination of the variability properties of the various agricultural trade-weighted exchange rate indices suggests that in modeling the agricultural trade-exchange rate relationship, the volatility of the exchange rate should be considered along with its level as explanatory variables.
