Book excerpt: Excerpt from Field Guide to the Common Diseases and Insect Pests of Oregon and Washington Conifers Phytophagous plant - eating) insects and tree pathogens (organisms that cause diseases of trees) are important components of coniferous forests in Washington and Oregon. They are most commonly known for causing individual tree-level impacts, such as growth reduction, breakage, deformity, and mortality. However, insects and pathogens do have significant effects on forest structure, species composition, and succession at stand and landscape levels. Insects and pathogens can influence the development and quality of wildlife habitat, watershed values, visual character, nutrient cycling, commodity production, and human safety. This field guide has been prepared to provide forest resource managers with a basic tool for quick field identification of diseases and insects that are commonly found affecting conifers in the Pacific Northwest. It does not attempt to describe or list all insects and pathogens found affecting coniferous trees, only those most commonly encountered. This field guide should be used in combination with other resources such as the books Western Forest Insects (furniss and Carolin 1977) and Diseases of Pacific Coast Conifers (scharpf Written descriptions, identification keys, comparative tables, photographs, and line drawings are used to illustrate and emphasize key characteristics that will help the user identify the common insects and pathogens during field reconnaissance.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Diseases of Pacific Coast Conifers This publication is a major revision of us. Department of Agriculture Handbook 521 first issued in 1978 and slightly revised and reissued in 1979. It has been updated to include new informa tion that will help identify many of the diseases of conifers growing along the Pacific Coast of western North America. The revisions have been made mainly to provide the latest information on diagnosis, nomenclature, and new diseases, and to expand the coverage of important diseases of the Pacific Northwest. The basic format of this handbook remains essentially the same as the original version. The expanded coverage, more and better illustrations, and new informa tion are designed to make this handbook a useful tool in diagnosing diseases of Pacific Coast conifers.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Insect Pests and Diseases of the Pecan But it is often a waste of time and money to apply insect and disease control measures to poor varieties or to trees that lack vigor because of inadequate soil fertility, overcrowding, or general neglect. To produce profitable crops, the pecan grower must adhere to cultural practices that pro mote tree vigor, stimulate fruiting, and minimize the damage caused by pests. For example, trees weakened by inadequate nitrogen fertilization and rank weed growth are more susceptible to damage by some leaf-spotting fungi. Conversely, too much nitrogen, which promotes season-long growth, can produce tender shoots that are highly susceptible to the scab fungus. Many disease organisms thrive under conditions that favor summer growth flushes. Practices that allow good air circulation such as wide spacing of trees, removal of lower limbs, and maintenance of low ground cover and hedgerows in summer facilitate disease and insect control. Ground sanitation is partially effective against most fungus diseases because the overwintering stage can often be eliminated. Ground trash such as broken limbs, shucks, and insect-infested nuts should be removed from the grove during the winter. Disking to turn under trash is not ad visable unless no other means of debris disposal is available. (disking can spread crown gall, and the resulting root pruning can lead to nutrient deficiencies, especially rosette.) This publication is not concerned with specific chemical control; the grower should refer to Stateextension service bulletins, which are updated often, or contact local extension service agents. Rather, our objective is to describe the biology of the insects and diseases and their symptoms in the grove and to outline general control measures.
