Description Tomato is one of the important vegetable crops grown extensively throughout the
tropical, subtropical and warm regions of the temperate zones of the world. Tomato
suffers from several diseases with substantial loss in yield of which Tomato mosaic is a
very severe disease causing heavy loss to the tomato growers in India.
The infected plants showed light and dark green mosaic areas on leaves and down
ward curling and mottling of leaves along the midrib region. The virus was readily sap
transmissible but not through aphids.
The virus had a limited host range and produced mosaic symptoms on Nicotina
tabaccum, mosaic and mottling symptoms on Datura stramonium, Capsicum annum,
Vigna unguiculata and Cucumis sativus, but necrotic local lesions on Chenopodium
amranticolor,Chenopodium quinoa and Nicotiana glutinosa.
The virus had TIP between 90 and 950 C, DEP between 10-6 and 10-7 and LIV of
30-35 days at room temperature (25-280 C). These studies indicated a strain of TMV
associated with tomato mosaic disease which was confirmed by electron microscopic
studies as rod shaped virus particles, approximately measuring 290 ±10 nm in size
resembling TMV particles were observed in infected leaves.
