TL;DR: Diversity of most fungal groups peaked in tropical ecosystems, but ectomycorrhizal fungi and several fungal classes were most diverse in temperate or boreal ecosystems, and manyfungal groups exhibited distinct preferences for specific edaphic conditions (such as pH, calcium, or phosphorus).
Journal ArticleDOI
New species from the Fusarium solani species complex derived from perithecia and soil in the old World tropics.
TL;DR: A large collection of strains belonging to the Fusarium solani species complex was isolated from soil and perithecia in primary forests in Sri Lanka and tropical Australia, finding all Sri Lankan and Australian soil isolates were found to be members of Clade 3, most grouping with the cosmopolitan soil-associated species F. falciforme.
Journal ArticleDOI
Effect of ammonium carbonate and sodium bicarbonate on anthracnose of papaya
TL;DR: Ammonium carbonate incorporated into the wax formulation effectively reduced anthracnose incidence by 70% in naturally infected papaya and extended the storage life by maintaining the firmness, color and overall quality of the fruit in low temperature storage.
Journal ArticleDOI
Use of sodium bicarbonate and Candida oleophila to control anthracnose in papaya during storage
TL;DR: Use of sodium bicarbonate at 2% with the antagonist C. oleophila is a promising alternative to chemicals to control anthracnose, a major postharvest disease on papaya during storage.
Journal ArticleDOI

TL;DR: An endophytic fungus isolated from surface sterilized leaf segments of Anoectochilus setaceus, an orchid endemic to Sri Lanka, and was identified as Xylaria sp.
