Ec81-1869 Guide To The Identification Of Physiological Disorders Of Landscape Plants, John E. Watkins, Donald H. Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

Physiological disorders are plant diseases caused by non-living agents. Other terms for this group of disorders are abiotic diseases or noninfectious diseases.

Physiological disorders are often confused with pathogen-caused diseases but they do not spread from plant to plant as do diseases caused by living organisms. Landscape plants are often exposed to toxic materials, mechanical damage, nutritional stress, homeowner neglect and other stress factors in the urban environment.

This 4-color extension publication highlights the following physiological disorders of landscape plants: sun scald, drought, lightning injury, winter injury, root girdling, iron chlorosis, salt injury, herbicide injury and air pollution.

Nebraskans are increasing their consumption of fresh vegetables — as appetizers, salads, side dishes, and snacks. Fresh vegetables are an integral part of a healthy, well-balanced diet. Although Nebraska's climate and soil are well-suited for many vegetables, most are supplied from out of the state, even during summer. Growing fresh vegetables can provide higher nutrition and flavor at less expense than buying fresh produce at the grocery store. A garden also can be a source of personal enjoyment and satisfaction.

This extension circular helps the gardener decide when, where, and how to plant and maintain a vegetable garden.
