• The leaves and stem are become straw colored.
• Affected plants wither and spread across the entire field.
• The roots of infected plants become brittle and dry.

 

                                     

 

Survival & Favourable Conditions

• Maximum temperatures above 30 degree and dry soil conditions and moisture stress promote
  disease development.

Cultural Control

• Deep ploughing in summer
• Grow cultivars resistant to dry root rot.
• Drought should be avoided.
• Sowing should always be done on the recommended time.
• Germinating and young seedlings should be saved from high temperatures.

Chemical Control

• Seed treatment with a mixture of Carbendazim 1.5 g and Thiram 1.5 g per kg of seed.
• Seed treatment with Trichoderma viride formulation + 3 g thiram per kg seed can reduce the disease incidence.
