Puccinia path in India is given by

Answer: Option A

Puccinia path in India is given by Nagarajan & Joshi.
The defined dispersal route from South to North is called the "Puccinia Path" of India. Unlike North America, the spread from the Nilgiris to central India is an independent event and there is no feedback of inoculum to the Nilgiris.
Long distance spread of the airborne wheat stem rust uredospores depends on upper-air weather patterns. Trajectories of the airborne inoculum at the 700 mb level led fro the nilgiris, the southern area to the secondary foci of infection.
