    Regional Copper-Nickel Study : Plant Diseases Affecting Forest Trees in Northeastern Minnesota's Regional Copper-Nickel Study Area
    (1978) Zeyen, Richard J; Groth, James V
    This report presents a series of tables of tree diseases in the region, as well as factual narrative descriptions. The document contains a table of common plant diseases for the region. The remainder of the report describes a variety of tree diseases and their symptoms and appearance. No conclusions or recommendations are included. The abstract and summary points are extracted and reproduced below. "This report is based upon lists of major vegetation community types, compiled for a preliminary study of the Regional Copper-Nickel Study Area. Only dominant plant species, as determined by releve techniques, have been included in the discussion of diseases. The intent of this report is to present a brief survey of the major diseases caused primarily by biotic agents. The information was obtained from general references and from personal observations of the diseases of the area over the past 11 years. The report is divided into two parts: (1) a comprehensive table of diseases recorded in the area and their causal agents (Table 1), and (2) brief descriptions of 25 diseases of exceptional economic or aesthetic importance."
