Foot Rot, Don Hudson

University of Nebraska-Lincoln Extension: Historical Materials

Foot rot (necrotic pododermatitis, foul foot) can be a very annoying problem in cattle. Once started in a herd and "seeded" in the soil, it may persist for quite a long time. Although the incidence of foot rot may not be high at any one time, it requires constant observation to prevent serious economic loss. The bacterium Fusobacterium necrophorum has been reported to cause foot rot. However, researchers have not been able to reproduce typical foot rot lesions with this organism. Recent research at the University of Missouri indicates that a combination of Fusobacterium necrophorum and Bacteroides melaninogenicus are the …

Tolerance Of The Rice Variety Triveni To The Brown Planthopper, Nilaparvata Lugens, D. T. Ho, E. A. Heinrichs, F. Medrano

Department of Entomology: Faculty Publications

Seedling screening and survival and population growth studies on 30-day-old plants indicated similar degrees of susceptibility on Taichung Native 1 (TN1) and Triveni rice to Nilaparvata lugens (Homoptera: Dilphacidae). However, studies in the screenhouse and field indicated that at both the vegetative and mature stage, Triveni possesses tolerance to insect damage, expressed as the ability to survive and produce a higher percentage of productive tillers than TN1 at similar N. lugens populations. Yield reduction caused by feeding of N. lugens was ca. 40% when infested with 400 N. lugens on 35-, 50-, or 75-day-old plants, whereas it was almost 100% …

Effects Of Insecticides On Nilaparvata Lugens And Its Predators: Spiders, Microvelia Atrolineata, And Cyrtorhinus Lividipennis, W. H. Reissig, E. A. Heinrichs, S. L. Valencia

Department of Entomology: Faculty Publications

Thirty-five insecticides used on rice in Asia were tested in the field against Nilaparvata lugens. The most important predators of the pest, Cyrtorhinus lividipennis, Microvelia atrolineata, and predacious spiders, Lycosa pseudoannulata, Tetragnatha, and Araneus species, were also monitored in the test plots. Ten insecticides significantly reduced numbers of N. lugens, but propoxur and ethylan gave the most consistent and effective control. Most insecticides did not significantly reduce populations of spiders and M. atrolineata compared with untreated checks, but they did reduce numbers of C. lividipennis. Fifteen treatments caused resurgence of N. lugens, …

Resurgence Of Nilaparvata Lugens (Stål) Populations As Influenced By Method And Timing Of Insecticide Applications In Lowland Rice, E. A. Heinrichs, G. B. Aquino, S. Chelliah, S. L. Valencia, W. H. Reissig

Department of Entomology: Faculty Publications

Resurgence of Nilaparvata lugens (Stål) after insecticide application is a common phenomenon in rice in South and Southeast Asia. Among other insecticides inducing resurgence, carbofuran, decamethrin, and methyl parathion were selected for this study. Of the various methods of carbofuran application tested, foliar sprays were most active in inducing resurgence. Extent of resurgence was highly influenced by time of insecticide application. Sprays of methyl parathion and decamethrin applied 50 and 65 days after transplanting (DT) induced resurgence in the third generation of N. lugens at ca. 90 DT, whereas earlier applications had little effect. The cause(s) for resurgence was not …

Selection Of Biotype Populations 2 And 3 Of Nilaparvata Lugens By Exposure To Resistant Rice Varieties, P. K. Pathak, E. A. Heinrichs

Department of Entomology: Faculty Publications

The release of an insect pest-resistant variety and subsequent adaptation of the insect species to that variety through the process of biotype selection has occurred on many cultivated crops. The present study was designed to obtain detailed information on some of the processes involved in the selection of biotypes of Nilaparvata lugens (Stål) on two rice varieties with different major genes for resistance. The N. lugens population selected for the study, which had originally been collected in the field and reared on a susceptible variety for 12 years (ca. 140 generations), initially had a low survival on the resistant rice …

Insecticide-Induced Resurgence Of The Brown Planthopper, Nilaparvata Lugens, On Rice Varieties With Different Levels Of Resistance, W. H. Reissig, E. A. Heinrichs, S. L. Valencia

Department of Entomology: Faculty Publications

Three rice varieties, IR29, IR40, and IR42, which are, respectively, susceptible, moderately resistant, and resistant to Nilaparvata lugens Stål in the Philippines, were treated in the field with decamethrin, an insecticide known to cause resurgence. N. lugens populations increased to a significantly higher level in the treated plots than in untreated checks, but the degree of resurgence varied among varieties. The maximum population increases in the treated plots compared with the checks were ca. 74-, 50-, and 5-fold, respectively, for IR29, IR40, and IR42. Decamethrin was toxic to predators, and this reduction of natural enemies of N. lugens may …

1982 Annual Report

Southeast Research and Extension Center: Reports and Administration

1982 was a year of challenges for all the various members of our unit including the researcher, the extension worker, the forester, and all the support staff. Our program year started on October 1, 1981 and ended on September 30, 1982.

From the agriculture standpoint, it has been a difficult year. The fall of 1981 was not favorable to the agricultural producer. Rain, freezing temperatures and even light snow was prevalent in October, 1981. Throughout the winter of 91-82, it was cold and snow was on the ground most of the winter.

It was not uncommon for counties in the …

G82-590 Feeder Cattle Grades, Keith E. Gilster, H. Dwight Loveday

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the ten USDA feeder cattle grades.

The purpose of the USDA Feeder Cattle Grades is to sort feeder cattle into similar groups that will facilitate their selling and buying. These grades can also be used for sorting feeder cattle into similar outcome groups in a feedlot. Differences in frame size and muscle thickness score are the basis for the USDA Feeder Cattle Grades.

Feeder cattle are given a grade score that is coded for both frame size (large, medium and small) and thickness (1, 2 and 3). For example, a large frame, thick feeder steer would have …

Heg82-158 Weatherizing Your Home--Weatherstripping, Kathleen Parrott

University of Nebraska-Lincoln Extension: Historical Materials

This guide discusses the practice of weatherizing your home through weatherstripping. Selection of materials, types of weatherstripping and buying and installing these products are discussed. Insulation is not the whole story for energy conservation! Even if your home is well-insulated, energy may be wasted through air infiltration. Air can leak around doors and windows, foundations, chimneys, exterior plumbing, etc. In the winter, air heated by your furnace is lost to the outside; in summer, hot outdoor air puts an extra load on your air conditioner. If your home is typical, one-half to three-quarters of your fuel bill is the result …

Ec82-1738 Tree Planting Guide, William R. Lovett, Bruce E. Bolander

University of Nebraska-Lincoln Extension: Historical Materials

Site Preparation

Proper site preparation is essential to your tree planting operation, and varies with the different climates and soil types.

Chemical Control: On sandy soils, rough terrain, or other highly erodible sites, tillage is not recommended. Chemical weed and/or grass killers may be applied to the site in the fall or before planting in the spring.

Summer Fallow: This practice is recommended on heavy soil in western Nebraska to conserve soil moisture. This may be accomplished with the aid of occasional disking, subsurface tillage, or chemicals to control weeds.

Fall Tillage: In the eastern areas of the state fall …

G82-600 Chimneys: Their Installation And Upkeep, Rollin D. Schnieder

University of Nebraska-Lincoln Extension: Historical Materials

Anyone who is thinking of putting in a wood stove has a lot of different things to consider. One of the most important is providing a good means for getting rid of combustion gases through some type of chimney. This may be a masonry chimney, some type of prefabricated chimney, or it may mean the repair of a chimney now on the house that may not have been used for many years.

All wood burning stoves need a tight, well-designed and properly constructed chimney to get rid of gases. This chimney must help in the efficient use of the stove …

G82-601 Using Phosphorus Fertilizers Effectively, E.J. Penas, D.H. Sander

University of Nebraska-Lincoln Extension: Historical Materials

For most effective use of phosphorus, the fertilizer needs to be placed to ensure quick contact by growing roots and minimal contact with the soil.

Phosphorus (P) fertilizers are second only to nitrogen fertilizers in importance for growing crops in Nebraska. However, the principles affecting efficient phosphorus use are totally different. Nitrogen is a mobile nutrient both inside the plant and in the soil, while phosphorus moves very little in the soil. In addition, total plant phosphorus requirements are much lower than those of nitrogen. Plant leaves commonly contain ten times more nitrogen than phosphorus. However, phosphorus is concentrated in …

G82-596 Use And Management Of Micronutrient Fertilizers In Nebraska, George W. Rehm, E.J. Penas

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide focuses on the use of the micronutrients zinc and iron.

Of the 16 elements known to be essential for plant growth, 7 are used in very small amounts and are classified as micronutrients. These are zinc (Zn), iron (Fe), manganese (Mn), copper (Cu), boron (B), molybdenum (Mo) and chlorine (Cl).

Micronutrients are supplied to plants from two sources: 1) soil minerals and 2) organic matter. They are released as the soil minerals break down over a period of time by weathering. The major portion of the micronutrients made available to plants, however, probably comes from the breakdown (mineralization) …

G82-587 Understanding Potassium For Crop Production In Nebraska, George W. Rehm

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the availability of and the need for potassium in Nebraska soils

Potassium (K) is an essential nutrient absorbed from soils by crops in relatively large amounts. Therefore, it is classified as a major nutrient. Although large amounts are absorbed, potassium is not necessarily needed in a fertilizer program. Numerous studies conducted with all major crops have definitely shown that adding potassium to a fertilizer program does not lead to yield increases on the large majority of soils in Nebraska.

G82-586 Effects Of Agricultural Runoff On Nebraska Water Quality, Elbert C. Dickey, Phillip Harlan, Don Vokal, C.J. Kisling-Crouch

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the effects of agricultural runoff on Nebraska water quality. Methods of controlling agricultural runoff are also examined.

The Federal Water Pollution Control Act Amendments of 1972 and the Clean Water Act of 1977 were written in response to a national concern for decreasing surface and groundwater quality. These laws set 1985 as a target date for eliminating pollutant discharges into navigable waters. An interim goal of the acts calls for "water quality which provides for the protection and propagation of fish, shell fish, and wildlife and provides for recreation in and on the water," where attainable, by …
