D. Heat treatment

Answer: Option B

Solution(By Examveda Team)

Loose smut is controlled by Seed treatment.
Since loose smut fungus depends on seed for its survival and carries over from one season to another, growing disease free seed is the only alternative method of control available at present for large scale adoption. Treat the seed with Vitavax at the rate of 2.5 g per kg of seed before planting.
Solar heat treatment of infected seed is highly valuable in the hot summer areas of the plains to make seed disease free. On a bright sunny day in the last week of May or first week of June. Soak the seed in water for about four hours in the morning and then dry it under hot sun in the afternoon. Store the well dried seed for use in next wheat season. The seed soaking activates the dormant fungus in the seed and heat of the sun kills it.
