G74-186 Cannas, Donald E. Janssen, Don Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

Cannas are quick growing, vigorous ornamental plants with heavy foliage and large flowers.

Flower colors range from dark red to light green. Leaf colors can be reddish-purple, bronze or green. They are used most effectively for bedding plants in public parks and larger home grounds where they can be planted in front of taller shrubbery and viewed from a distance. Their vigor and size make them less desirable for planting in restricted areas.

G74-113 A Quick Test For Atrazine Carryover (Revised March 1989), Alex Martin, R.N. Stougaard, Patrick J. Shea

University of Nebraska-Lincoln Extension: Historical Materials

How can you tell if you have atrazine carryover in your fields? Plants grown in soil samples can tell.

Residues of atrazine may remain in the soil and affect some susceptible crops the next year. Crops most often affected include soybeans, field beans, sugarbeets, alfalfa, oats, wheat and many broadleaf horticultural crops.

Attempts to predict the extent of carryover and damage to sensitive crops the year following atrazine use have been only partially successful. The rate of atrazine disappearance and, therefore, the amount remaining the next year, is affected by soil texture, pH and organic matter content, as well as …

G74-202 Wheat Soil-Borne Mosaic Disease (Revised October 2001), John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Host range, symptoms, disease cycle, and control options for wheat soil-borne mosaic disease are discussed.

Wheat soil-borne mosaic virus affects wheat (Triticum aestivum L.) growing primarily in central, eastern and west central Nebraska. This disease occurs annually; however, its effect on crop production in Nebraska varies from year to year due to variety selection, cropping practices and environmental conditions favoring disease development. In years when spring temperatures remain cool for extended periods, the virus remains active in infected plants, enhancing symptom development and increasing yield loss. The virus reduces tillering and affects kernel weights and test weights.

This insect is the most serious insect pest of iris in Nebraska and is found virtually everywhere in the state. Damage is characterized by dark, streaked, or watery areas and ragged edges on the developing leaves of iris in May and June and extensive destruction of the insides of the rhizomes in July and early August. Examination late in summer will reveal a large white to pinkish caterpillar from 1 1/2 to 2 inches long in the rhizome, usually accompanied by a foul-smelling soft rot.

G73-60 Working With Wood I. Home Drying Lumber (Revised July 1987), Michael Kuhns, Richard Straight

University of Nebraska-Lincoln Extension: Historical Materials

Avoid the expense of kiln-dried lumber by processing and drying your own lumber at home.

Anyone who has done much woodworking knows how expensive high quality, kiln-dried, hardwood lumber can be. Even kiln-dried construction lumber is expensive. Besides expense, there also may be problems with finding certain species of wood, highly figured wood, or hardwood boards thicker than one inch (4/4).

One way to avoid these problems is to dry your own lumber. Green, unsurfaced, or unplaned lumber can be obtained from many small sawmills in Nebraska and surrounding states. You may also want to obtain your own logs and …
