G94-1220 Controlling Ticks, John B. Campbell, Gustave D. Thomas

University of Nebraska-Lincoln Extension: Historical Materials

Identification and control of ticks common to Nebraska.

Ticks are members of the same phylum (Arthropoda) of the animal kingdom as insects, but are in a different class (Arachnida). The main difference is the body of a tick is composed of only two sections while insect bodies have three sections.

There are over 800 species of ticks, 100 of which are important to man and animals because of economic losses or disease transmission. Fortunately in the United States, only about 12 species are economically important because they transmit disease organisms (viral, bacterial, protozoan, and rickettsial) or cause economic losses to …

Ec94-138 Pigweed Identification: A Pictorial Guide To The Common Pigweeds Of The Great Plains, M.J. Horak, D.E. Peterson, D.J. Chessman, L.M. Wax

University of Nebraska-Lincoln Extension: Historical Materials

Several pigweed species are found in the Great Plains. Pigweeds commonly reduce crop yields and interfere with harvest. One means of controlling these weeds is through the use of herbicides. Recent research indicates that some pigweed species respond differently to various herbicides; therefore, proper identification is needed for good control.

This extension contains a generalized distribution map; photographs of seeds, seedling, and mature plants; and text describing other identifying features for each pigweed species. The species are grouped with others that have similar shape and form. The pigweed species listed in this publication are: redroot pigweed, smooth pigweed, Powell amaranth, …
