1973年以来,我们在福建从南到北的20个县、市发现了一种新的水稻病毒病——水稻簇矮病(bunchy stunt,原称类普矮病dwarf—like)。病株矮缩、丛生、并不黄化,有些象普矮,但不具普矮病叶的黄白色条点,往往簇生如草,有的还节上生枝、簇生小叶,形成“雀巢”状物;病害仅能通过黑尾叶蝉(Nephotettix cincticeps)和二点黑尾叶蝉(N.impicticeps)传播。带毒的黑尾叶蝉可终身传毒,但有明显的间歇现象,不经卵传播。电光叶蝉(Recilia dorsalis)、白翅叶蝉(Empoasca Subrufa)、褐飞虱(Nilaparvata lugens)和缢管蚜(Rhopalosiphum padi)均不传病;病土、
Since 1973, we have discovered a new type of rice virus disease-clustery stunt (formerly known as dwarf-like) in 20 counties in south-north Fujian. The plant dwarf, tufts, not yellow, some like Pu short, but not with the short yellowish white point of the disease, tend to cluster as grass, and some also on the branches, clusters of leaflets, the formation of “Nestle” ; Disease can only be transmitted by Nephotettix cincticeps and N.impicticeps. Poisonous black leafhopper can be lifelong poisoning, but there is a clear intermittent phenomenon, without egg transmission. Recilia dorsalis, Empoasca subrufa, Nilaparvata lugens and Rhopalosiphum padi did not transmit disease,
