Pitch Canker of Slash Pine in Florida
Journal of Forestry, 1977Abstract Pitch canker is reducing growth and deforming stems of large numbers of planted slash pines (Pinus elliottii Englem. var. elliottii) in Florida. In fall, needles on cankered shoots turn yellow to reddish. New shoots often wilt and die the following spring because the pitch-soaked cankers have girdled the branches.

The Epidemiology of Pitch Canker of Monterey Pine in California
Forest Science, 2002Abstract The progression of pitch canker disease, caused by Fusarium circinatum, was followed over 4 yr (1992–1996) in urban stands of Monterey pine, Pinus radiata, with initially zero, light, moderate, and severe disease intensity. The disease progressed from a few to many branch tip symptoms, followed by the appearance of cankers on ...

Effects of Fertilization on Healthy and Pitch Canker-Infected Pines
Southern Journal of Applied Forestry, 1981Abstract The addition of large amounts of nitrogen plus phosphorus fertilizer to a slash pine (Pinus elliottii var. elliottii Engelm.) stand infected with pitch canker increased mortality and decreased tree growth. The addition of nitrogen or phosphorus alone, small amounts of nitrogen plus phosphorus, or nitrogen, phosphorus, potassium,

A LAMP Assay for Rapid Detection of the Pitch Canker Pathogen Fusarium circinatum
Plant Disease, 2023The pine pitch canker pathogen Fusarium circinatum is endemic in the southeastern United States and Central America and represents an invasive threat globally. This ecologically adaptable fungus readily infects all parts of its pine hosts, leading to widespread mortality of nursery seedlings and decline in the health and productivity of forest stands.

Pitch Canker Damage to South Florida Slash Pine
Journal of Forestry, 1963Abstract Observations of incidence, rate of spread, and effect on tree growth and mortality of pitch canker disease caused by Fusarium lateritium f. pini were made in pulpwood-size stands of South Florida slash pine (Pinus elliottii var. densa). Incidence increased rapidly over a 5-year period, but was not correlated with either tree

Treatment of Pitch Canker on Monterey Pine with Fungisol Injection
Arboriculture & Urban Forestry, 1988Fungisol injections into mature Monterey pines with pitch canker, caused by Fusarium subglutinans, failed to eradicate pre-existing branch infections and did not prevent disease when trees were artificially inoculated or infected naturally.

A global climatic risk assessment of pitch canker disease
Canadian Journal of Forest Research, 2009Pitch canker is a devastating disease of Pinus spp. and Pseudotsuga menziesii (Mirb.) Franco. The pathogen responsible for this disease, Fusarium circinatum Nirenberg & O'Donnell, has spread to many countries within the last three decades. The susceptibility of the widely planted commercial species Pinus radiata D.Don to this pathogen has been of ...

Pitch Canker, A New Disease of Some Southern Pines
Journal of Forestry, 1946Abstract A new and highly lethal canker of southern pines is described. The causal agent has been isolated and identified, as a species of Fusarium.

Genetic Strategies for Reducing Pitch Canker Incidence in Slash Pine
Southern Journal of Applied Forestry, 1988Abstract Seedlings or ramets from 224 slash pine (Pinus elliottii var. elliottii Engelm.) clones were evaluated for resistance to the pitch canker fungus Fusarium moniliforme var. subglutinans Wollenw. & Reink. (FMS). Heritabilities and associated genetic gains calculated in five field tests suggest that pitch canker incidence can be

Increased risk of pitch canker to Australasia under climate change
Australasian Plant Pathology, 2011Pitch canker is a varied and complex disease of Pinus species. Despite the establishment of this disease in many countries, it has been difficult to predict how Fusarium circinatum would behave if introduced into Australia or New Zealand. To understand the potential risk this pathogen poses to the forest industries in Australasia, the process-oriented ...
