Diseased Turnip: Call for Help!

Turnip may not be one among the best vegetables- some people in town may not have seen one yet, but people of Haa have woven their lives with it. Infertile soil deprived of favorable weather conditions forced Haaps to make their living by herding yaks and turnip is one among a handful of crops grown in Haa. Turnips goes in making the region's famous recipe- Haapy Hoenty. The leaves of turnip are dried to make Lhoom, which then becomes very good combination with phaksha seekham and shakam.
However, the harvest looks bad this year. During my recent home going, I found all the turnips in our garden yellowed and dying. My mother wasn't surprised, she told me that a disease had been spreading in the region for last two years. Once infected the turnip buds turns into chain of three balls(see the picture), something similar to radish and then dies out gradually. I inquired if they have reported to the agricultural officer of the region, to which they gave a casual no. Perhaps they didn't know that they needed help. How come people don't know that there is an office who could help? How come the three year old disease didn't receive remedy so far?
