Available in PDF, EPUB and Kindle. Book excerpt: Over the last fifty years, there has been an increasing recognition that eucalypts are vulnerable to a wide range of diseases. They have suffered destructive epidemics, particularly of dieback caused by the cinnamon fungus in native forests, of foliar diseases and cankers in plantations, and of dieback of remnant trees on agricultural and grazing land. This has stimulated intensive research into the causes and management of diseases of the eucalypts. This work represents a comprehensive review of our current knowledge of the health and diseases of eucalypts.

Available in PDF, EPUB and Kindle. Book excerpt: Pine forests face a global threat of pine wilt disease, which is being spread by vector beetles carrying pathogenic nematodes from dead trees to healthy ones. Among the host pines there are varying degrees of susceptibility, and nematode strains also contain a variety of virulences, both of which factors help to determine whether infected host trees will die or survive. As well, biotic and abiotic environmental factors influence the fate of infected trees. This book describes the history of the disease, pathogenic nematodes, vector beetles, the etiology and ecology of the disease, microorganisms involved, and control methods that utilize host resistance and biological control agents. Concrete, comprehensive, and the most up-to-date knowledge about this worldwide forest epidemic is presented for readers, enabling them to understand the nature and epidemic threat of pine wilt disease.

Book excerpt: Forest Microbiology, Volume Two: Forest Tree Health highlights a range of emerging microbial phytopathogens of forest trees, along with novel approaches for managing tree pests and diseases in a changing climate. The book provides an overview of selected microbial pathogens of forest trees, with an emphasis on their biology, lifecycle, spreading mechanisms, impact on affected tree species and current and prospective control strategies. At the same time, the impact of tree microbiomes on host fitness is discussed. Beneficial components of tree microbiota are presented, along with their functional role in tree nutrition, immunity and disease resistance. In addition, this volume addresses the many functions of microbial disease agents of trees including fungi, bacteria, viruses and phytoplasma. Strong emphasis is placed on the genetics, biochemistry, physiology, evolutionary biology and population dynamics of the microorganisms involved. This title is a key resource for foresters and forest pathology practitioners, as well as plant biologists.

Available in PDF, EPUB and Kindle. Book excerpt: This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1913 edition. Excerpt: ...for which it has sometimes been mistaken. It appears on the leaves as scattered circular whitish spots, equally prominent on both surfaces, and about-inch in diameter. The leaves soon turn yellow and fall, and sometimes the attack is so severe that the trees are defoliated within a month. In fact, the trees are often seen loaded with fruit but entirely defoliated. On the young shoots the spots are whitish and usually elongated. They become dry, crack, and the 1 Syn. Pistillina jlavida, Speg. fragments of bark break away in flakes, leaving the brown wood exposed. On the berries these spots are usually whitish and almost circular. In fruiting (conidial form) the fungus produces yellowish pin-like structures which stand at right angles to the surface and bear the conidiophores. This fungus was first described by Cooke as Stilbum Jlavidum, with Stilbella jlavida, Lindau, as a variant. But Massee has found the perfect or ascigerous stage and described it as Sphaerostilbe Jlavida, Massee (" Coffee Disease of the New World," in Kew Bull. Misc. Inf. 1909, No. 8). It is frequently confused with mancha, which is due to a small moth, Cemiostoma coffeella, and which is distributed throughout the greater part, and possibly all of the coffee-growing countries of America. The disease also occurs on other plants than the coffee, and this increases the difficulty in controlling it. It has been reported from Central America, Colombia, Venezuela, Dutch Guiana, Brazil, Porto Rico, Dominica, Mexico, Trinidad, and Jamaica. This disease is most destructive where the shade is excessive, and the removal of the excessive shade growths so as to allow access of sunlight and air is the only practical remedy. Cutting out and burning of the diseased parts and...
Download or read book Ganoderma Diseases of Tropical Crops written by Carmel A. Pilotti and published by CABI. This book was released on 2023-11-28 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fungal genus Ganoderma includes around 80 currently recognized species that are widely distributed in temperate, subtropical and tropical regions, and cause disease in a range of economically important perennial crops and tree-like plants. Ganoderma root and lower stem rots have a significant impact on yields from crops including oil palm, coconut, beverage crops, Acacia and rubber. The identification of species responsible for stem and butt rots is often ambiguous as closely related species may only be distinguished by subtle morphological differences. Within species there can be considerable morphological plasticity and this can make morphology-based identification difficult, particularly for species described from a single specimen. Molecular techniques are helping to slowly resolve Ganoderma taxonomy but it will be some time (if ever) before the taxonomy is fully resolved. This book brings together information on Ganoderma species that are reported to be responsible for crop diseases in tropical and sub-tropical agriculture and covers taxonomy, biology, genetics, aetiology, epidemiology and control. This book is an essential resource for researchers in Ganoderma in crop science and tropical agriculture, as well as practitioners and industry.
