Description This paper reports the elimination of Indian
citrus ringspot virus (ICRSV) from “kinnow” (Citrus
nobilis Lour × Citrus deliciosa Tenora) employing
phytotherapy coupled with shoot tip grafting under in
vitro conditions. Nodal segments from infected mother
plant (indexed by indirect enzyme-linked immunosorbent
assay [ELISA] and reverse transcriptase PCR [RT-PCR])
were cultured on Murashige and Skoog medium containing
2iP (1 mg/l or 4.9 μM) and malt extract (800 mg/l)
along with different concentrations of aqueous extracts
from leaves of Azadirachta indica (Neem), Sorghum
vulgare (Jowar), and roots of Boerhaavia diffusa (Punarnava).
Shoot tips were excised from the nodal sprouts and
grafted on to rough lemon (Citrus jambhiri) under aseptic
conditions. Maximum effect (50% virus elimination) was
seen for aqueous leaf extracts of A. indica followed by B.
diffusa root extract (42.86%) and S. vulgare leaf extract
(31.58%). Plants/plantlets were considered virus-free only
when showing negative reactions by both indirect ELISA
and RT-PCR.
