Solution(By Examveda Team)

Potato spindle tuber disease is transmitted mechanically.
The disease is mechanically transmitted by contact between healthy and diseased plants, tractor wheels, tools, etc. Within potato plants, it is found most readily in the upper leaves and tubers.
Transmission in the true seed of potato depends upon the cultivar. This disease can pass through both the pollen and ovule.
