The virus is found to be transmitted by Thrips palmi and Thrips tobacci in persistent manner. No seed transmission is observed. Virus showed same physical properties as it shows in stem necrosis of peanut or sunflower necrosis disease. The physical properties are found to be thermal inactivation point (TIP) 55–600C, dilution end point (DEP) 10-2 -10-3 and longevity in vitro (LIV) 5 Hrs, virus infecting nineteen of different host plants are identified belonging to five different types of families viz.malvaceae, chenopodiaceae , compositae ,leguminaceae and solanaceae. However they found to produce same types of symptoms as in most of the host that have been tested before.
