Tungro is one of the most destructive viral disease of rice in South and Southeast Asia. It is associated with two viruses—rice tungro bacilliform virus (RTBV) and rice tungro spherical virus (RTSV) (Hibino et al 1978). Both viruses are transmitted by the green leafhopper (GLH) Nephotettix virescens (Ling 1979). However, prior acquisition of RTSV is required for the transmission of RTBV alone (Hibino 1983). Plants infected with both viruses show severe stunting and yellowing. Those infected with RTBV alone show mild stunting but no leaf discoloration whereas those infected with RTSV alone do not show any apparent symptoms (Hibino et al 1978).
