Diseases woody plants

If you have space, woody items can just be stacked in an out-of-the-way corner and left to decay over a period of years. They will make a valuable wildlife habitat (see also pp.108-111). Some may be suitable for use around the garden, as plant supports, for example. Your local waste disposal site may recycle woody items if you cannot. Avoid bonfires, which cause pollution and nuisance, unless you need to dispose of diseased woody plant material.

Reforestation. With tissue culture and rapid mass multiplication of stocks of woody plants, reforestation following disturbance has become more targeted. The forester can readily access seedlings adapted to the site, with built-in insect and disease resistance. Species such as the American chestnut, eliminated from most of its original range by blight in the early... 

Many of the compounds are rather common and are widely distributed among woody plants. However, they rarely occur in abundant quantities. Some of the compounds possess significant biological properties - e.g. they contribute to the resistance of plants to disease, pest insects, or grazing and foraging animals. The roles that many of the compounds play in the plants are, however, to a large extent unknown. None of the compounds included in this section has commercial use, but some of them contribute to the properties of the wood and influence the properties and the processing of forest products. 

Only live, clean plants free of insects, disease, molds, bryophytes, etc. are included. The collection of sample parts depends on plant habit, characteristics, and abundance. Woody species may be divided into several samples of leaves, twigs, bark, wood, roots, and fruits. Herbaceous plants, when abundant, are divided into aerial and below-ground parts otherwise they are collected as whole-plant samples. Samples are weighed fresh, before freezing.

Crop Rotation—Pathogenic organisms nearly always can be carried over from one growing season to the next in the soil or in plant debris. Continual production of the same or closely related crops on the same piece of land leads to a disease buildup. Crop rotation reduces the buildup of pathogens, but seldom provides complete disease control. Obviously, crop rotation is not always possible, practical, or desirable. Perennial crops such as trees, woody ornamentals and turfgrass must remain in one location for many years. Some crops, such as com, cotton, or wheat, often are more practical to grow on the same land year after year despite the potential for a buildup of plant disease pathogens. 

Plants Affected A wide range of woody and herbaceous plants. This disease is a serious problem on grapes. 

The typical dictionary definition of herb includes the fact that it is a plant that does not develop persistent, above-ground woody tissue and that it is used for both medical reasons and for flavoring foods. Professor Varro Tyler, a world-famous pharmacy educator, takes this definition a step further and presents it in a fashion truly relevant to pharmacy crude drugs of vegetable origin utilized for the treatment of disease states, often of a chronic nature, or to attain or maintain a condition of improved health. 1...
