SummaryDothistroma needle blight (DNB), caused by the two fungi Dothistroma septosporum and D. pini, is a major disease of pines with a worldwide distribution. Increases in the incidence and severity of disease in areas where the disease has long been established and notable range expansions have both recently been observed. The aim of this review was to assess the relationship between DNB, weather factors and climate to better understand possible underlying causes of this recent intensification in disease. A substantial body of literature shows that the life cycles of the fungi are closely related to weather factors such as precipitation and temperature. Given the rapid response of DNB to favourable weather conditions, it seems plausible that changes in disease behaviour could be due to changes in climate. The recurrent El Niño-Southern oscillation (ENSO) phenomenon influences patterns of temperature and precipitation in many regions of the world, often resulting in warmer and wetter conditions than normal. We found that since the 1950s, four of the past five strong El Niño events appear to have coincided with reports of increased DNB activity on an intercontinental scale. The lack of long-term standardized data records limits our ability to fully interpret this relationship, but the projected future climatic conditions in the Northern Hemisphere appear to be increasingly favourable for the disease. Still, other areas of the world may become less favourable, and further research is required to be able to accurately predict DNB outbreaks and their impact on pine forests in the future.

“…In New Zealand, Gilmour (1981) showed that peaks in disease severity coincided with periods of rainfall, with little or no infection during dry periods. Other studies in Britain, Bulgaria, Hungary, Canada, USA, Chile, Colombia and Kenya also noted a clear link between high summer rainfall and high disease severity (Archibald & Brown, 2007;Dubin, 1967;Fraser, Mullett, Woodward, & Brown, 2016;Gibson et al, 1964;Koltay, 2015;Murray & Batko, 1962;Rodas et al, 2016;Rogerson, 1953;Woods et al, 2005;Zlatanov, 1977).…”

Summary Dothistroma needle blight (DNB) caused by Dothistroma septosporum and Dothistroma pini is a damaging disease of pine in many countries. The disease led to the abandonment of planting susceptible Pinus species in parts of Africa, Asia, Australasia, Europe and North America. Although the disease can be effectively controlled using copper fungicides, this chemical is only routinely applied in forests in New Zealand and Australia. Other management tactics aimed at making conditions less favourable for disease development, such as thinning or pruning, may be effective on some, but not all, sites. Disease avoidance, by planting non‐susceptible species, is the most common form of management in Europe, along with deployment of hosts with strong disease resistance. Although D. septosporum is present almost everywhere Pinus is grown, it is important that an effort is maintained to exclude introductions of new haplotypes that could increase virulence or enable host resistance to be overcome. A global strategy to exclude new introductions of Dothistroma and other damaging forest pathogens, facilitated by collaborative programmes and legislation, is needed.

Development of microsatellite markers for the pine needle blight pathogen, Dothistroma pini

Dothistroma needle blight of Pinus spp. is a serious disease that can be caused by two distinct fungal species: Dothistroma septosporum and D. pini. Dothistroma septosporum has a broad pine host range, a worldwide distribution and has caused many serious epidemics. In contrast, D. pini has a more limited distribution; known only from Europe and the USA. Unlike the situation for the better-known D. septosporum, the population biology of D. pini has not been intensively studied. Microsatellite markers developed for D. septosporum either do not amplify in D. pini or they are uninformative. The aim of this study was to develop a robust set of microsatellite markers that amplify across different D. pini isolates from a range of geographical locations and different host species. The genome of an isolate from Ukraine was sequenced using Mi-Seq Illumina sequencing. Thirty-two primer pairs were designed to amplify microsatellite regions targeting a mixture of di-, tri-, tetra-, penta-and hexa-nucleotide repeat regions. The results yielded 16 polymorphic markers that amplified across 32 isolates from seven countries and four hosts. Screening of the polymorphic markers on a population of D. pini from France and Slovenia revealed that the Slovenian isolates were clonal but that those from France were genetically more diverse. The markers developed in this study will provide a useful tool with which to study the population structure and genetic diversity of D. pini populations in countries where it is emerging as an important pathogen.
