It is a seed-borne disease in wheat crops. The symptoms of this disease appear only after the Bali stage. Instead of grains, spores of the pathogen are found in the form of black powder in the ears of diseased plants and these spores are covered with a thin membrane. Affected plants usually mature earlier and have a shorter height.
Preventive measures for loose smut disease:
Seed treatment is the best way to control this disease. Remove infected spikes when leaves turn yellow. Apart from this, spray Carmanova (Carbendazim 12% + Mancozeb 63%) @ 600 gm/acre or Tesu Nova (Tebuconazole 10% + Sulphur 65% WG) @ 500 gm per acre in 200 litres of water to control the disease.
