The 15 known viruses that occur in rice are rice black-streaked dwarf, rice bunchy stunt, rice dwarf, rice gall dwarf, rice giallume, rice grassy stunt, rice hoja blanca, rice necrosis mosaic, rice ragged stunt, rice stripe necrosis, rice stripe, rice transitory yellowing, rice tungro bacilliform, rice tungro spherical, and rice yellow mottle viruses. This paper describes their geographical distribution, relation to vectors, infection cycles, field dispersal, and development, and lists recorded outbreaks of the viruses. Many rice viruses have become serious problems since rice cultivation has been intensified. Double-cropping of rice using improved, photo-insensitive cultivars of short growth duration has significantly influenced the incidence of these viruses.

水稻病毒的生物学和流行病学。

水稻中发生的15种已知病毒是水稻黑纹矮化，水稻矮化特技，水稻矮化，水稻矮化，水稻giallume，水稻草特技，水稻霍亚布兰卡，水稻坏死性花叶病，水稻衣衫st的特技，水稻条纹坏死，水稻条纹，水稻短暂泛黄，水稻通格杆菌形，球形通格和黄色斑驳病毒。本文描述了它们的地理分布，与载体的关系，感染周期，田间传播和发展，并列出了已记录的病毒爆发。自从加强水稻种植以来，许多水稻病毒已成为严重的问题。使用改良的，对光不敏感的，生长时间短的栽培品种对水稻进行两次播种，对这些病毒的发生率产生了重大影响。
