Sphaeropsis tip blight is caused by the fungus, Sphaeropsis sapinea (also known as Diplodia pinea). It is one of the most destructive fungal diseases of pine trees in the Midwest. It is most common on Austrian pine but can also damage Scotch pine (Scots pine), ponderosa, and mugo pine Sphaeropsis sapinea. The name changed back to Diplodia pinea tip blight (fungus) Diplodia tip blight, also called Sphaeropsis blight, is caused by the fungus Sphaeropsis sapinea. This can be a destructive and devastating disease of pines. Austrian, black, mugho, red, and Scots pine are very susceptible although other species are also affected, especially when growing under conditions of stress As Sphaeropsis sapinea (Fr.)

Sphaeropsis sapinea (Fr.:Fr.) Dyko and Sutton, is among the most common and widely distributed pathogens of conifers worldwide. S. sapinea is disseminated over short distances by rain splash and moist wind, but significant knowledge gaps regarding long-range dispersal remain • Sphaeropsis sapinea can act as a latent pathogen; physiological alteration, through water stress, can effect release from the quiescent condition to result in rapid disease development S. sapinea may rapidly become pathogenic, leading to sudden disease outbreaks [13-15]. Ghelardini et al. [16] considered that cryptic and latent pathogens, such as S. sapinea, are the most important drivers of emerging fungal diseases in forests. Sphaeropsis sapinea is

Diplodia tip blight, previously known as Sphaeropsis tip blight, is a common fungal disease of stressed conifers, especially pines with needles in bunches of 2's and 3's. Austrian pine (Pinus nigra) is the most susceptible host, although the following pines are also susceptible:. The ascomycete Sphaeropsis sapinea is the causal agent of the Diplodia Tip Blight disease on pines and other conifer species. This fungus has a symptomless endophytic life stage. Disease symptoms become visible when trees have been weakened by abiotic stress, usually related to warmer temperatures and drought. Currently, this disease is observed regularly in Scots pine (Pinus sylvestris) sites.

Four morphotypes of S. sapinea have been described from within the natural range of the fungus, while only one morphotype has been identified on exotic pines in the Southern Hemisphere

Diplodia pinea (synonym Sphaeropsis sapinea) är en svampart [17] som orsakar en svampsjukdom som drabbar tallar över hela världen. Sphaeropsis sapinea ingår i släktet Sphaeropsis, divisionen sporsäcksvampar och riket svampar. [18] [19] Inga underarter finns listade i Catalogue of Life. [18]Skadegöraren är vanlig i Sydeuropa, men har på senare år [] rapporterats längre norrut. SYNOPSIS. Sphaeropsis sapinea (=Diplodia pinea) causes shoot blight, canker, collar rot, root disease and blue stain of Pinus spp. In South Africa, it has restricted the cultivation of Pinus radiata almost entirely to the South-Western Cape. It is also important on Pinus patula growing in the summer rainfall areas. Favourable conditions for infection are wet weather and high temperatures (25.

Sphaeropsis sapinea was associated with the noninoculated seedlings used in the current experiments more frequently than in our earlier studies.

Two new 5-substituted dihydrofuranones, named sapinofuranones A and B (1 and 2), were isolated from liquid cultures of Sphaeropsis sapinea, a phytopathogenic fungus causing a wide range of disease symptoms on conifers. A fungal strain isolated from Cupressus macrocarpa produced both 1 and 2 at concentrations higher than those produced by the strain isolated from Cupressus sempervirens. Sphaeropsis sapinea is a cosmopolitan fungus, identified in more than 50 countries of the world, on all continents, but it is primarily the species of warm lands. It is also a polyphagous fungus recorded from 11 coniferous genera.

Cankers caused by the fungus Sphaeropsis sapinea (Fr.) Dyko and Sutton damage many conifers worldwide, especially pines planted outside their native ranges. Severe episodes of Sphaeropsis canker lead to crown wilting and top and branch dieback, resulting in extensive economic losses in plantations (2, 3, 7, 8,10) and deformities in landscape. The fungus (Sphaeropsis sapinea) infects young, healthy, unwounded needles of new candles (new growth), which is where we see the typical blighting of branch tips. All needles in the terminal six inches or so of growth turn brown and dry out. This phase of the disease is unsightly but does not cause branch death
