Abstract A description is provided for Lophodermella cerina. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus contorta, Pinus elliottii var. elliottii, Pinus ponderosa, Pinus taeda. DISEASES: Needle cast of pines. Symptoms on first-year needles have been reported to appear in November on southern pines, with the ascomata visible by late February and prominent by the end of March. Czabator et al. (1971) stated that two years' needles are affected, though it is not clear whether this means there are two sets of infected needles on a tree at the same time. All ages of pines in the southern USA have been reported to be infected, though the disease was more common in older stands, and while the infection was scattered within a stand, whole crowns of individual trees are affected. Severe and repeated attacks by L. cerina on pine species in the western USA did not cause significant mortality. GEOGRAPHICAL DISTRIBUTION: USA (Alabama, Arizona, California, Colorado, Florida, Louisiana, Mississippi, New Mexico). TRANSMISSION: By airborne ascospores in wet or humid conditions.

HOSTS: Pinus contorta, Pinus edulis, Pinus flexilis, Pinus monophylla. DISEASES: Needle cast of pines. Little is known of the biology of B. pini, but the fact that this species fruits mainly on needles more than two years old suggests that it is unlikely to be a serious pathogen.

Abstract A description is provided for Lophodermella montivaga. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus attenuata, Pinus contorta. DISEASES: Needle-cast of pines. This fungus has been reported to have a 1-year life-cycle, with ascospores mature from July to October, and germinating by a short germ tube to produce an appressorium from which an infection peg was thought to penetrate the cuticle of new needles. In Colorado the first symptoms have been reported in September: the needles turned brown, and ascomata developed in them over winter. The influence of this species on individual trees and on stand growth has not been assessed. GEOGRAPHICAL DISTRIBUTION: USA (California, Colorado, Idaho, Montana, Oregon, Washington, Wyoming). TRANSMISSION: By airborne ascospores in wet or humid conditions.

Abstract A description is provided for Davisomycella ponderosae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus ponderosa. DISEASES: Needle cast of pines. The fungus fruits on dead needles, or on dead portions between green parts of otherwise living needles. Trees from 1.5-9 m high have been affected, those in the higher range being affected only in the lower crown, while foliage throughout the crown of smaller trees showed symptoms. Most observations have been of the fungus fruiting on needles still attached to the tree, frequently attacking only one or two needles of a bundle. Needle bundles with attacked needles were often observed to be shed prematurely. Ascospore discharge has been observed between mid-July and mid-August, though ascomata containing spores which could germinate have been collected as late as mid-October (44, 892). GEOGRAPHICAL DISTRIBUTION: USA (Colorado). TRANSMISSION: By airborne ascospores in wet or humid conditions.

Abstract Herbicide treatments were used at four flatwood locations in north Florida and south Georgia to compare early pine response to control of herbaceous and shrub vegetation following bedding. Treatments consisted of three levels of shrub control (none, first year, repeated) with and without first year herbaceous vegetation control. All studies were located on spodosols planted with either loblolly (Pinus taeda L.) or slash (Pinus elliottii Englem.) pine. Responses due to shrub control were about twice that of herbaceous control with height responses of 2.2, 5.0, and 6.9 ft due to first year herbaceous control, shrub control, and the combination of both herbaceous and shrub control, respectively. Pine response did not differ due to duration of shrub control because the difference in shrub cover between first year and repeated shrub control treatments was minor in these young stands. Pines averaged 18.3 ft in height and 3.2 in. in dbh 5 yr after planting when both herbaceous and shrub vegetation was controlled with these operational-like site preparation treatments that combine bedding with first year herbicide applications. Shrub occupancy was highest on treatments that did not include shrub control and continued to increase through the first 5 yr. Operational site-preparation treatments that combine bedding with herbicide applications should be considered in situations where shrub vegetation is present because of the long-term impact that shrubs have on pine yield.

Abstract A description is provided for Lophodermella concolor. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus banksiana, Pinus contorta, Pinus contorta var. murrayana. DISEASES: needle cast of pines. Lophodermella concolor is a strong pathogen with a 1-year life cycle (12, 254). New needles are infected in June and July, and turn reddish-brown about nine months later, becoming somewhat greyish brown when the ascomata start to appear in May. Infected needles are dwarfed and appear tufted. Infection is more or less even on young crowns, but on older trees the lower crown is most heavily infected, with often only the current year's needles remaining. Needle-cast occurs 12-14 months after initial infection at, or slightly before maturation of the ascomata. The disease leads often to almost entire defoliation, which may result in shoot and branch death (12, 254; Mielke, 1956). Where tree mortality due to L. concolor occurs, it is most likely to be in highly susceptible, low-vigour or stressed trees in overstocked stands (Williams, 1976). Root diseases and bark beetles may be contributory factors. Severe infection occurs in areas where fog or mist are common, and high precipitation probably increases disease incidence (Mielke, 1956). Resistant trees, which come from among the tallest and most vigourous, have been selected for inclusion in a P. contorta improvement programme, but results of any further work on resistance have not yet been reported. GEOGRAPHICAL DISTRIBUTION: Canada (Alberta, British Columbia, Ontario, Saskatchewan), USA (Colorado, Idaho, Montana, Oregon, Wyoming, Utah). TRANSMISSION: by airborne ascospores in wet or humid conditions.
