DOWNLOAD EBOOKThe bean crop of the Southwest suffers severe injury from the bean ladybird, which sometimes ruins entire crops. It is restricted to beans for food and attacks all kinds. Both beetles and their larvæ devour all parts of the plant -- leaves, flowers and pods -- but the chief injury is to the foliage. The pest can be controlled in small areas by hand-picking the overwintered beetles and by brushing the larvæ or young from the plants during hot, dry weather. On a larger scale it may be controlled by spraying with arsenite of zinc, arsenate of lead, or arsenate of lime. Clean cultivation should be practiced and early and late planting." -- [2]

DOWNLOAD EBOOKIntroduction to Forestry and Natural Resources, Second Edition, presents a broad, completely updated overview of the profession of forestry. The book details several key fields within forestry, including forest management, economics, policy, utilization and forestry careers. Chapters deal specifically with forest regions of the world, landowners, forest products, wildlife habitats, tree anatomy and physiology, and forest disturbances and health. These topics are ideal for undergraduate introductory courses and include numerous examples and questions for students to ponder. There is also a section dedicated to forestry careers. Unlike other introductory forestry texts, which focus largely on forest ecology rather than practical forestry concepts, this book encompasses the economic, ecological and social aspects, thus providing a uniquely balanced text. The wide range of experience of the contributing authors equips them especially well to identify missing content from other texts in the area and address topics currently covered in corresponding college courses. - Covers the application of forestry and natural resources around the world with a focus on practical applications and graphical examples - Describes basic techniques for measuring and evaluating forest resources and natural resources, including fundamental terminology and concepts - Includes management policies and their influence at the local, national and international levels
