Ec02-1565 Biology And Management Of Potato Insects, Robert J. Wright, Gary L. Hein, W. Wyatt Hoback, Alexander D. Pavlista Jan 2002

Ec02-1565 Biology And Management Of Potato Insects, Robert J. Wright, Gary L. Hein, W. Wyatt Hoback, Alexander D. Pavlista

Historical Materials from University of Nebraska-Lincoln Extension

A variety of insects can damage potatoes in Nebraska. Insects may feed directly on the tubers and damage the harvestable crop, or they may indirectly damage the crop by feeding on leaves or stems. If severe enough, indirect damage may reduce harvestable yield and quality. Insect feeding also may be important because some insects (e.g., aphids) may transmit plant diseases such as viruses when they feed, or others (e.g., psyllids) may inject toxins. This publication reviews the identification, biology, and management of common insect pests of potatoes in Nebraska. The basis for a successful integrated pest management (IPM ...

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 Jan 2002

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

Historical Materials from University of Nebraska-Lincoln Extension

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.


Ec02-174 Leafy Spurge, Robert A. Masters, Brady F. Kappler Jan 2002

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

Historical Materials from University of Nebraska-Lincoln Extension

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 ...


Ec02-171 Canada Thistle, Robert G. Wilson Jan 2002

Ec02-171 Canada Thistle, Robert G. Wilson

Historical Materials from University of Nebraska-Lincoln Extension

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.


Ec02-177 Purple Loosestrife, Stevan Z. Knezevic Jan 2002

Ec02-177 Purple Loosestrife, Stevan Z. Knezevic

Historical Materials from University of Nebraska-Lincoln Extension

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 of mechanical ...

Ec02-176 Musk Thistle, Fred Roeth, Steven R. Melvin, Irvin L. Schleufer Jan 2002

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

Historical Materials from University of Nebraska-Lincoln Extension

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 herbicide ...

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 Jan 2002

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

Historical Materials from University of Nebraska-Lincoln Extension

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 ...
