control of rice tungro disease

Tungro, the most important virus disease of rice in south- east Asia, effects annual losses in excess of $1.5 x 109. (Herdt, 1988). It is caused by a complex of two viruses. (Saito et al., 1976; Hibino et al., 1978). Rice tungro spherical virus (RTSV) is transmitted in a semipersistent manner by the green leafhopper, Nephotettix
ABSTRACT. Rice tungro, the most important virus disease of rice in South and Southeast Asia, is caused by a complex of two viruses, rice tungro bacilliform virus (RTBV) and rice tungro spherical virus (RTSV). RTBV is a plant pararetrovirus with bacilli- form particles, the structure of which is based on T = 3 icosahedral

Abstract: As the most devastating viral disease of rice in South and Southeast Asia, rice tungro disease remains one of the significant fears to sustainable annual rice productions in the world. Due to the increasing world population and subsequent increase in demand for food, identifying the causal agents and symptoms.
Abstract. Stunting was severe in susceptible rice (Oryza sativa L.) cultivar. 'Taichung Native 1' infected with tungro virus (RTV) compared to less-susceptible cultivar 'IR 20'. The senescence of detached leaves of RTV-infected susceptible cultivar incubated in water in dark was accelerated compared to the healthy leaves as
“Tungro" disease of rice (Oryza sativa L.) is caused by a virus transmitted by the rice green leafhopper Nephotettix impicticeps Ishi- hara (1). The rice tungro virus (RTV) seems to be nonpersistent in the rice green leaf- hopper (Z), an exception to the general pic- ture of the leafhopper-borne viruses. Pre- liminary results of an
Rice Tungro Virus (RTV). RTV can appear at any time on rice right from seedling stage. Tungro affected plants are: stunted in growth, reduced tillering, young leaves are pale green to yellow, while older leaves are reddish orange in colour. Infected leaves often dry up quickly, if plants are infected during early states, delayed.
