Cyclaneusma needle cast : ウィキペディア英語版 | Cyclaneusma needle cast
''Cyclaneusma'' (needle cast) is a fungal disease that is apart of the phylum, Ascomycota. It infects plants that are of pine classification.〔Peterson, Glenn W., and James A. Walla. "Naemacyclus (Cyclaneusma) Needle Cast of Pines." (n.d.): n. pag. Web. .〕 After infection by ''Cyclaneusma'', most pines do not display symptoms until 10 months after the initial infection. Symptoms include needles developing yellow spots, horizontal brown bands around the needles, swelling of needles, and off-white fruiting bodies formed on infected needles.〔SLJ. "Cyclaneusma Needle Cast of Pines." Cornell University Department of Plant Pathology and Plant-Microbe Biology (2012): n. pag. Web. 21 Oct. 2014.〕〔"CYCLANEUSMA NEEDLE CAST Cyclaneusma minus (Butin) DiCosmo, Peredo, and Minter (syn. Naemacyclus Minor Butin)." (n.d.): 34-36. Web. 21 Oct. 2014.〕 Because ''Cyclaneusma'' is an ascomycete it produces two spore types, an asexual (conidiomata) and sexual (ascomycota) spore. Controlling ''Cyclaneusma'' has presented a challenge as the disease can survive on both living and dead needles during the winter months. Effective management methods include planting new pines in non-shaded, well drainable soil as well as spraying fungicide. ''Cyclaneusma'' Needle Cast is an important fungal disease because it directly impacts the commercial value of decorative pines as well as lumber. == Hosts and Symptoms ==
