Ec05-185 Grazing Winter Wheat In Nebraska, Tom Holman, Drew J. Lyon, David D. Baltensperger, Ivan G. Rush, Ray Weed

University of Nebraska-Lincoln Extension: Historical Materials

Grazing cattle on winter wheat, often prior to grain harvest, is common throughout the southern Great Plains. Grazing generates about $50 million in income for Texas wheat producers and reduces the risk of growing wheat by providing a substantial income source other than grain. Benefits can be realized by grazing prior to the primary environmental risk period for drought, heat stress, and hail, all of which frequently reduce grain yield while having limited impact on forage production. Cattle also are grazed on winter wheat fields in western Nebraska and the surrounding region. Typically in Nebraska, fall forage would be used …

Nf560 Wheat Disease Fact Sheet No. 2: Management Program For Foliar Leaf Spot Diseases Of Wheat, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

This NebFact addresses symptoms and management of foliar leaf spot diseases in wheat.

Foliar leaf spot diseases in wheat occur in spring and summer. Tan spot is characterized by small brown, oval lesions with tan centers early on. Later large tan blotches have a yellow halo. Septoria leaf blotch is characterized by tan irregularly shaped blotches with black specks and a yellow margin. Septoria leaf and glume blotch is characterized by brown irregularly shaped blotches on leaves, purple-brown lesions on glumes and black specks absent from lesions.

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 …

Ec02-173 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 …

G99-1389 Cultural Practices To Improve Weed Control In Winter Wheat, Gail A. Wicks, Alex Martin, Drew J. Lyon

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains the influence of cultural practices on weeds in winter wheat. Precipitation and temperature greatly influence crop and weed growth in the semiarid areas of the central Great Plains. Precipitation in Nebraska varies from 14 to 24 inches where fallow is practiced. The purpose of fallow is to control weeds and, when not cropping a field, to store water and stabilize winter wheat fields. With good prewheat-fallow techniques, sufficient soil moisture is usually available to establish winter wheat. Peak rainfall occurs in May and June during the pollination and grain-filling period of winter wheat. The latter part of …
