G89-925 'Helminthosporium' Leaf Spot And Melting Out Diseases Of Turfgrass (Revised December 1995), John E. Watkins, Roch E. Gaussoin, Terrance P. Riordan

University of Nebraska-Lincoln Extension: Historical Materials

Symptoms and controls for "Helminthosporium" leaf spot and melting out are discussed.

Leaf spot and melting out are two fungal diseases of turfgrass within the "Helminthosporium" leaf, crown and root disease complex. They are the most common and serious groups of cool season turfgrass diseases in North America.

G89-951 Mushrooms, Puffballs, Fairy Rings, And Slime Molds In Turfgrass, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

How do you identify -- and treat -- mushrooms, puffballs, fairy rings and slime molds? Read on.

Some mushrooms and most puffballs are edible; some are foul-smelling, many are considered unsightly, and a few are poisonous; but when they appear on a lawn, most are considered a nuisance.

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.

G89-955 Nozzles — Selection And Sizing (Revised February 2003), Robert N. Klein, William P. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

The proper selection of a nozzle type and size is essential for proper pesticide application. The nozzle is a major factor in determining the amount of spray applied to an area, the uniformity of application, the coverage obtained on the target surface, and the amount of potential drift. This NebGuide covers nozzle description, recommended uses and orifice sizing for sprayers.

Ec89-730 Anti-Pollution Protection When Applying Chemicals With Irrigation Systems, Dean E. Eisenhauer, Delynn R. Hay

University of Nebraska-Lincoln Extension: Historical Materials

Many irrigators apply chemicals such as fertilizers, herbicides, and insecticides with their irrigation systems. This practice, called chemigation, can be an effective applicatio method if the chemical is suited to this practice and the irrigation system is properly engineered. Chemigation is regulated in Nebraska. The Department of Environmental Control (DEC) and the Natural Resource Districts (NRDs) conduct impsection and enforcement programs. This guide describes only the equipment requirements of DEC's regulations.

G89-902 Intensive Gardening Techniques, Betty Besal

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes techniques which will allow the gardener to grow more vegetables where space may be limited.

For some people, a small-sized garden is preferable to a larger one. Smaller gardens require less labor and expense than larger gardens. Decreasing garden size provides more yard space for other activities. The gardener can concentrate soil improvement efforts in a smaller area, and, with careful management, small gardens can produce sufficient vegetables for fresh eating during the growing season, and perhaps extra produce for preserving.

G89-897 Strawberries, Don Steinegger, Donald E. Janssen

University of Nebraska-Lincoln Extension: Historical Materials

Plants, selecting and preparing a site, planting and care of strawberries are covered in this NebGuide.

Strawberries are a popular, dependable fruit for home production. Management of this crop is easier than that of tree fruits.

G89-954 A Guide For Managing Poultry Insects (Revised April 1996), John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Major insect pests of Nebraska's poultry population are identified and treatment recommendations are given.

For many years poultry production in Nebraska has consisted primarily of large operations of layer hens. In recent years, however, broiler production has increased in southeast Nebraska. There are also some large turkey production units. Extreme competitiveness in the poultry industry has resulted in narrow cost-profit margins. Poultry operations cannot allow ectoparasitic and nuisance insects to interfere with production, nor can they afford high pest control expenses. For production to be profitable, poultry production must be managed to reduce the incidence of insect pests.

Poultry are …

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 …

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.
