Sp341-G Corn Earworm On Sweet Corn, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

The corn earworm, Helicoverpa zea (Boddie), is the most serious insect pest of sweet corn in Tennessee. This pest feeds directly on the market product.

Sp341-K Common Stalk Borer In Field Corn, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

The common stalk borer in Tennessee is reported to attack several crops in addition to field corn. However, the preferred host of the insect is giant ragweed. This preference is due to the largeness of the stem in which the larvae can mature. Fields of corn planted into a no-till situation are preferred by the moths because of the grassy weeds in those fields. The adult moth deposits eggs on grassy weeds in the early spring. Later, the larvae will migrate to any corn planted in the fields.

Sp341-Y Western Corn Rootworm, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Three species of corn rootworms are found in Tennessee. The Western corn rootworm is the most destructive of the three species. This insect is now prevalent from Texas to the Dakotas, and has moved into Tennessee within the past 10 to 15 years. Until 1955, this rootworm was found in Nebraska, Colorado, Kansas, South Dakota and Iowa. The Western corn rootworm has traditionally moved into the territory of the Northern corn rootworm, which is also found in Tennessee.

Effects Of Grazing Residues Or Feeding Corn From A Corn Rootworm-Protected Hybrid (Mon 863) Compared With Reference Hybrids On Animal Performance And Carcass Characteristics, K. J. Vander Pol, Galen E. Erickson, N. D. Robbins, L. L. Berger, C. B. Wilson, Terry J. Klopfenstein, E. P. Stanisiewski, G. F. Hartnell

Department of Animal Science: Faculty Publications

One grazing and two feeding experiments were conducted to compare the feeding value of corn residue or corn grain from a genetically enhanced corn hybrid (corn rootworm-protected; event MON 863) with nontransgenic, commercially available, reference hybrids. In Exp. 1, two 13.7-ha fields, containing corn residues from either a genetically enhanced corn rootworm- protected hybrid (MON 863), or a near-isogenic, nontransgenic control hybrid (CON) were divided into four equal-sized paddocks. Sixty-four steer calves (262 ± 15 kg) were stratified by BW and assigned randomly to paddock to achieve a stocking rate of 0.43 ha/steer for 60 d, with eight steers per …

Do Arctic-Nesting Geese Compete With Sandhill Cranes For Waste Corn In The Central Platte River Valley, Nebraska?, Gary L. Krapu, David A. Brandt, Robert R. Cox Jr.

Proceedings of the North American Crane Workshop

Numbers of arctic-nesting geese staging in spring in the Central Platte River Valley (CPRV) of southcentral Nebraska increased dramatically from the 1970s to the 1990s, raising concerns that geese may be competing with the mid-continental population of sandhill cranes (Grus canadensis) for waste corn. From late February to mid-April 1998-2001, we measured temporal patterns of cropland use, evaluated habitat preferences, and compared numbers of geese using the primary crane-occupied parts of the CPRV area with numbers of sandhill cranes. Numbers of Canada geese (Branta canadensis), lesser snow geese (Chen caerulescens)/ Ross’ geese (Chen …

Evidence Of A Decline In Fat Storage By Midcontinental Sandhill Cranes In Nebraska During Spring: A Preliminary Assessment, Gary L. Krapua, David A. Brandt, Deborah A. Buhl, Gary W. Lingle

Proceedings of the North American Crane Workshop

When an ice storm killed an estimated 2,000 sandhill cranes (Grus canadensis) in the Central Platte River Valley (CPRV) in Nebraska on 24 March 1996, we retrieved the fresh carcasses of 118 adults to test for a decline in the condition of spring-staging cranes from that date in 1978 and 1979. We first conducted a principle component analysis on 3 morphological variables (tarsus, exposed culmen, and wing chord [flattened]) and used the first principal component (PC1) as an index of body size. Then, to account for variation in body mass due to size, we regressed body mass on …

University of Nebraska-Lincoln Extension: Historical Materials

This report contains historical price data for the major crops and livestock commodities produced in Nebraska. Prices received by producers are reported for 1960-2005 for most of the commodities.

The data was compiled from Nebraska Agricultural Statistics Service and Agricultural Prices, National Agricultural Statistics Service, USDA; Oil Crops Situation and Outlook, Economic Research Service, USDA; Cotton and Wool Outlook, Economic Research Service, USDA; and Livestock and Grain Market News, Agricultural Marketing Service, USDA. Sources of prices for each commodity are indicated on the tables.

Ec05-130 Guide For Weed Management In Nebraska, Roch E. Gaussoin, Brady F. Kappler, Robert N. Klein, Stevan Z. Knezevic, Drew J. Lyon, Alex Martin, Fred Roeth, Gail A. Wicks, Robert G. Wilson, Robert A. Masters, Patrick J. Shea, Larry D. Schulze

University of Nebraska-Lincoln Extension: Historical Materials

One of the major thrusts of all University of Nebraska weed science faculty is the Guide for Weed Management in Nebraska. This guide is not just the work of one or two people, rather it is a joint effort of all the authors to produce a comprehensive, information-packed resource. Each weed science faculty member is responsible for particular sections of the guide. The process of reviewing the current content, checking labels and research data and updating the content can be an extensive process. Each year new herbicide active ingredients and trade names are introduced and figuring out what a herbicide …
