Ec03-177 Noxious Weeds Of Nebraska: Purple Loosestrife, Stevan Z. Knezevic

University of Nebraska-Lincoln Extension: Historical Materials

Purple loosestrife is an introduced invasive weed that is overrunning 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. This Extension Circular discusses the biology, identification, distribution and control of purple loosestrife.

Ec03-176 Noxious Weeds Of Nebraska: Musk Thistle, Fred Roeth, Steven R. Melvin, Irvin L. Schleufer

University of Nebraska-Lincoln Extension: Historical Materials

Musk Thistle 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. This Extension Circular discusses the history, biology, identification, distribution and control of the musk thistle.

G03-1526 Prevention And Control Of Rabbit Damage, Dallas R. Virchow, Scott E. Hygnstrom, Dennis M. Ferraro

University of Nebraska-Lincoln Extension: Historical Materials

Cottontail rabbits (Sylvilagus spp.) and jackrabbits (Lepus spp.) are found in most of Nebraska. The eastern cottontail (S. floridanus) lives throughout the state while the desert cottontail (S. audubonii) lives only in western Nebraska. Black-tailed (L. californicus) and white-tailed jackrabbits (L. townsendii) are most common in the western two-thirds of Nebraska.

This NebGuides describes how to identify rabbit damage and recommends proper methods of control, such as fencing, habitat modification, repellents, trapping, and shooting to reduce damage to tolerable levels.

G03-1522 Damping Off Of Seedlings And Transplants, Laurie Hodges

University of Nebraska-Lincoln Extension: Historical Materials

The shift toward more ecological means of pest control is a driving force in research and in growers' fields. Growers need to understand how the various pathogens causing plant disease respond to environmental conditions and cultural practices — what keeps the level of disease below an economic threshold and how these conditions can be developed and maintained for more sustainable production.

This NebGuide provides information on two common pathogens that cause seedling disease (damping off) in many crops. Although vegetable production is used in the examples, the principles apply to many cropping systems.

Hotcaps are covers used to protect individual plants from low temperature stress early in the season. There are three common hotcap designs: opaque plastic milk jugs, waxed paper, and plastic water-filled tubes. They are usually used by home gardeners or market gardeners with limited production. Growers with more acres or more extensive production tend to use row covers or high tunnels that protect more than one plant.

This NebFact discusses the study methodology, findings, and conclusions to using hotcaps in the garden.

Nf03-571 Aspergillus Flavus And Aflatoxins In Corn, Jim Stack, Michael Carlson

University of Nebraska-Lincoln Extension: Historical Materials

The severe weather conditions of the 2002 growing season resulted in an increase in the incidence and severity of aflatoxin contamination of both food grade and feed grade corn in Nebraska.

The mycotoxin called aflatoxin is produced by the grain mold Aspergillus flavus. Not all isolates of A. flavus produced aflatoxin and isolates that are capable of producing aflatoxin do not always synthesize the toxin. Many factors including environmental conditions and host suscepbitility, determine the incidence and severity of grain mold and subsequent mycotoxin contamination.

This NebFact discusses the cause and occurrence of aflatoxin in corn; the effects it has …

Nf03-570 Fumonisins In Corn, Jim Stack, Michael Carlson

University of Nebraska-Lincoln Extension: Historical Materials

During the past two years, millers have rejected some Nebraska food grade corn because it was contaminated with the mycotoxin fumonisin. Most of the contaminated samples and the highest levels of contamination were detected in corn from counties in the eastern half of Nebraska.

Fumonisins are mycotoxins produced by the grain molds Fusarium verticillioides and Fusarium proliferatum. These fungi are commonly found in corn throughout the United States.

G03-1521 Using Corn Hybrid Yield Data To Improve Selection Of Rapidly Changing Hybrids, Robert N. Klein, Lenis Alton Nelson, Roger Wesley Elmore

University of Nebraska-Lincoln Extension: Historical Materials

Choosing the proper hybrid can greatly enhance crop production profitability. This NebGuide illustrates how to use corn hybrid test data and adjust it to your farm when selecting seed. How often should you change hybrids? An Auburn University study compared the top corn hybrids from a 3-year regional trial (114 bushel average) with the top hybrids from the previous year's test (119 bushel average). Since the yields went from 114 to 119 bushels - a 5 bushel increase - using data from 11 locations and 8 years, should we expect twice that difference - a 10 bushel increase - with …
