Nf02-518 Management Of Phytophthora Diseases Of Soybeans, Loren J. Giesler, Jane A. Christensen, Christopher M. Zwiener

University of Nebraska-Lincoln Extension: Historical Materials

Phythophthora diseases of soybean, caused by Phytophthora sojae, are present wherever soybeans are grown in Nebraska. The pathogen survives primarily as "resting" spores in the soil or in association with infested crop debris. Symptoms associated with Phytophthora sojae, infections include seed rots, pre- and post-emergence dampin goff of seedlings and stem rot of plants at various growth stages.

Knowledge of the races present in the state and how varieties with different resistance genes have performed in a grower's field is critical to variety selection for maximum profitability.

Nf02-506 Plant Disease Central Web Site, Jim Stack

University of Nebraska-Lincoln Extension: Historical Materials

Disease is a natural part of every crop production system. This is true for all crop species and for each type of production system; irrigated or rain-fed, conventional or conservation tillage, and continuous or rotational cropping. In any given year, the question is which diseases will occur in Nebraska's field crops and at what incidence and severity.

To help producers, consultants, and other agricultural professionals diagnose and manage field crop diseases in Nebraska, the Plant Disease Central (PDC) web site was developed. The home page includes instructions on navigating the site under the "About This Site" link.

Ec02-177 Purple Loosestrife, Stevan Z. Knezevic

University of Nebraska-Lincoln Extension: Historical Materials

Purple loosestrife (Lythrum salicaria) is an introduced invasive weed that isover running thousands of acres of wetlands and waterways in the Midwest. Once purple loosestrife invades a wetland, natural habitat is lost and the productivity of native plant and animal communities is severely reduced. These losses in turn interfere with various levels of the ecosystem and area recreational activities such as fishing, boating and hunting, diminishing revenue from tourism and impairing the social and economic well being of local communities. A single control measure cannot provide long-term, sustainable control of this weed. An integrated approach, using a variety …

Ec02-174 Noxious Weeds Of Nebraska: Leafy Spurge, Robert A. Masters, Brady Kappler

University of Nebraska-Lincoln Extension: Historical Materials

Leafy spurge is an invasive weed that infests over three million acres in the northern Great Plains and the prairie provinces of Canada. It is commonly found in rangelands, pastures, roadsides, rights-of-way, and woodlands. Leafy spurge can reduce rangeland and pasture carrying capacity by as much as 75 percent because it competes with forages and cattle avoid grazing areas infested with this weed.

This Extension Circular discusses the biology, identification, distribution and control of leafy spurge.

Ec02-179 Managing Livestock Manure To Protect Environmental Quality, Michael A. Reynolds, Brian L. Benham, Richard B. Ferguson, Christopher G. Henry, Charles A. Shapiro, James P. Stack, Charles S. Wortmann

University of Nebraska-Lincoln Extension: Historical Materials

This book covers the land application part of manure management. With increasing regulations, the livestock producer needs to understand the scientific principles that affect manure transformations and how to use these principles to manage the manure for maximum fertilizer value with minimal environmental impact. Improved land application of manure is one part of the solution, but we suggest that the producer evaluate the quantity of nutrients arriving on the farm as feed, animals, and fertilizer compared to the total that is exported. Achieving a nutrient balance will reduce potential environmental hazards often associated with animal agriculture.

Ec02-173 Spotted And Diffuse Knapweed, Neil L. Heckman, Ryan M. Goss, Roch E. Gaussoin, Stevan Z. Knezevic, John L. Lindquist

University of Nebraska-Lincoln Extension: Historical Materials

Spotted knapweed (Centaure amaculosa Lam. = C. biebersteinii DC.) and diffuse knapweed (C.diffusa Lam.) are two of Nebraska’s seven noxious weeds. They are also noxious in at least 17 other states. These are closely related species that are well adapted to a variety of habitats including open forests, rangelands and pastures, Conservation Reserve Program lands, roadsides, and ditch banks. Centaurea is a large genus of over 400 species, 32 of which are common weeds of the United States and several of which [e.g., yellowstar thistle, C. solstitalis L, and Russian knapweed, C. repens L. =Acroptilon repens (L.) …

Ec02-172 Plumeless Thistle, Kara L. Hilgenfeld, Alex Martin

University of Nebraska-Lincoln Extension: Historical Materials

Plumeless thistle (Carduus acanthoides L.) is one of seven noxious weeds in Nebraska. An introduced invasive broadleaf weed native to Europe and Asia, plumeless thistle currently infests about 65,000 acres in Nebraska. Infestations of plumeless thistle may reduce productivity of pastures and rangeland, where infestations tend to be the largest. Plumeless thistle competes with and suppresses growth of desirable species. Heavy infestations prevent livestock from grazing the area and lighter infestations prevent livestock from eating plants growing near the thistle. Estimates place the annual loss in Nebraska agricultural production due to plumeless thistle at $162,000. Although plumeless thistle is …

Ec02-171 Canada Thistle, Robert G. Wilson

University of Nebraska-Lincoln Extension: Historical Materials

Canada thistle [Cirsium arvense (L) Scop.] is one of the seven species defined by Nebraska law as a noxious weed. At least 35 other states also have determined by law that Canada thistle poses a threat to the economic, social, and aesthetic well-being of the residents of their state. Canada thistle is probably the most widespread of all the thistle species and many land managers consider it the most difficult thistle to control. In Nebraska, Canada thistle is estimated to infest 460,000 acres.

Ec02-176 Musk Thistle, Fred Roeth, Steven R. Melvin, Irvin L. Schleufer

University of Nebraska-Lincoln Extension: Historical Materials

Musk thistle (Carduus nutans L.) is an introduced invasive broadleaf weed native to Europe, North Africa, and Asia. In these areas it is a minor weed because natural enemies keep its population low. When the plant was introduced into North America, its natural enemies were left behind. Without these natural checks, the thistle is able to thrive and compete with native vegetation.

Musk thistles aggressively invade all lands in Nebraska. Typical cropland weed control methods are very effective against them; however, land with permanent cover (pasture, range, roadway ditches and wasteland) that is not tilled or treated with a …

Ec02-174 Leafy Spurge, Robert A. Masters, Brady F. Kappler

University of Nebraska-Lincoln Extension: Historical Materials

Leafy spurge is an invasive weed that infests over three million acres in the northern Great Plains and the prairie provinces of Canada. It is commonly found in rangelands, pastures, roadsides, rights-of-way, and woodlands. Leafy spurge can reduce rangeland and pasture carrying capacity by as much as 75 percent because it competes with forages and cattle avoid grazing areas infested with this weed. In North Dakota where leafy spurge infests about 900,000 acres, estimates of direct and indirect losses exceed $100 million each year. In Nebraska, the direct loss in forage value attributed to leafy spurge has been estimated at …

G02-1465 Crop Water Use In Western Nebraska, C. Dean Yonts

University of Nebraska-Lincoln Extension: Historical Materials

Whether your water originates from the ground or the river, water for irrigation is becoming limited due to diminishing supplies and increasing environmental needs. In many areas of the Nebraska Panhandle, groundwater levels are dropping due to over development of the aquifers. In river valleys, water shortages occur during periods of drought.

This NebGuide provides information on average weekly crop water use values for the major crops grown in western Nebraska. The information is best used for planning decisions before the season begins or for long term irrigation system planning.
