What is a common method used to control common bunt in wheat?

• A. Application of herbicides
• B. Use of resistant varieties
• C. Reducing irrigation
• D. Delayed planting

Answer: (B)

Using resistant varieties is a widely accepted method for controlling common bunt in wheat. Common bunt, caused by the fungus Tilletia tritici, can significantly reduce wheat yields. By planting wheat varieties that have been bred to resist this disease, farmers can effectively minimize the incidence of infection and prevent the spread of the pathogen within their fields. Resistant varieties have specific genetic traits that help them withstand the fungal attack, leading to healthier crops and improved overall yield.

The other approaches listed do not specifically target the fungal pathogen that causes common bunt. While herbicides can control weeds, they do not affect fungal diseases. Reducing irrigation might help with fungal diseases in some cases, but it is not a direct control method for common bunt specifically. Similarly, delayed planting could be based on specific agronomic practices or conditions, but it does not guarantee control over common bunt, as the disease can still initiate from infected seed or soil, regardless of planting timing. Therefore, implementing the use of resistant varieties is the most effective and commonly practiced method for managing common bunt in wheat production.
