Abstract:
In the late winter of 1988, pairs of slash pine (Pinuselliottii Engelm.) trees were chosen and marked on the Harrison Experimental Forest in Gulfport, Mississippi. One tree of each pair had a blight and the associated fungi Lophodermellacerina Darker on all mature needles, while the other tree had healthy needles. The blight recurred on the same study trees in 1989 and 1990. Analysis of tree cores shows that the blighted member of each pair has had less radial growth than the clean (nonblighted) pair member since about 1971, when a severe needle blight occurred throughout the slash pine region

Abstract:
A field study determined an optimal approach for the remote sensing of a pine needle blight of unknown cause that occurs frequently in the southeastern United States. Needle spectral reflectance was measured in five pairs of slash pines (Pinuselliottii Engelm. var. elliottii), each comprising a blighted and a nonblighted tree. Reflectance of blighted needles generally was greater within the 400–700 nm wavelength range and less in the 720–850 nm range compared with nonblighted needles (p ≤ 0.050). The relative change in reflectance, or reflectance sensitivity to the blight, was greatest near 68

The largest reflectance difference occurred on the shoulder of the near-infrared region at 763 nm. Wavelengths of greatest sensitivity to D. septosporum infection were located in the rang

Abstract:
Dothistroma needle blight is a serious foliar disease in Australian Pinus radiata plantations causing defoliation, decreased productivity and, in extreme cases, tree death. Conventional methods of monitoring forest health such as aerial survey and ground assessments are labor intensive, time consuming, and subjective. Remote sensing provides a synoptic view of the canopy and can indicate areas affected by damaging agents such as pests and pathogens. Hyperspectral airborne remote sensing imagery (CASI-2) was acquired over pine stands in southern New South Wales, Australia which had been ground

The epidemiology of D. septosporum in Britain, from its behaviour and effects in a forest stand to its spread and population biology was investigated in this thesis. The peak infection period for the pathogen was determined to be spring and summer (June to September) albeit with low levels of infection occurring throughout the year. Contrary to previous belief the pathogen was found to have more than one life cycle per year in England. This is undoubtedly a factor contributing to the severity of the disease seen in this country.

The leaf and shoot blight disease known locally as Daño Foliar del Pino (DFP) is the most important problem affecting Chilean Pinus radiata plantations. The disease is typified by needle infections, exudation of resin at the bases of needle brachyblasts and necrotic lesions in the cambium of younger trees, which eventually girdle branches. The disease causes death of seedlings young trees and mature trees can also succumb after a few years of successive infection. DFP emerged very recently and its cause was unknown.

Abstract:
Trees and forests are under increasing threat from pathogens which cause huge economic and ecological damage. The unprecedented global movement of pathogens into new areas creates novel pathosystems, while the changing climate affects the dynamics of endemic pathosystems. Co-evolution within endemic pathosystems affects the genetic composition of hosts and pathogens. Spatial heterogeneity in pathogen pressure leads to genetic variation in disease-related traits among host populations. In contrast, novel hosts or populations are expected to be highly susceptible to exotic pathogens as there has

For them, this was the bright side of the catastrophe of World War II, and they envisioned a thorough modernization of the urban fabric. Consequently planners disliked the term Wiederaufbau—reconstruction—because it suggested a return to prewar conditions rather than a future orientation.
