Answer 1

Correct Answer - Option 4 : D

The correct answer is D.

• Karnal bunt is also called a partial bunt.
• It is caused by the fungus Tilletia indica which infects grains at flowering. 
• It reduces grain quality through the production of masses of powdery spores that discolor the grain and grain products.
• The name 'Karnal Bunt' comes from the city of Karnal in Haryana.
• The most susceptible hosts of the disease are-
  • wheat
  • durum wheat
  • triticale
• Karnal bunt spreads mainly through the movement of infected grain. However, teliospores can be carried on machinery, trucks, animals, and anything that disturbs and moves the soil.
• Since only a few grains in each wheat head are infected, it is easiest to detect symptoms after the grain has been harvested.
