Loose smut disease in wheat

• This is a seed-borne disease and it’s caused by a fungus called Ustilago Segetum.

• The infected seed appears to be healthy.

• Symptoms of this disease are visible only when spikes are formed.  

• In spikes of infected plants, black powder (spores) is found instead of grains, which also infects seeds produced in other healthy spikes by being suspended in the air.

• Seed treatment is the best way to control this disease.

• Apart from this, for the control of this disease use Kasugamycin 5% + Copper oxychloride 45% WP @ 300 gm or Hexaconazole 5% SC @ 400 ml or Tebuconazole 10% + Sulfur 65% WG @ 500 gm/acre  

• Spray Pseudomonas fluorescens @ 250 gm/acre as a biological treatment.
