    When false smut happens?
     
    False smut usually happens at following conditions:
    1. Susceptible variety of rice or wheat seed to false smut
    2. umidity of air reaches more than 90 percent and temperature is in between 25 – 35°C
    3. Later seeding of rice or wheat
    4. Inadequate plough of field
    5. High nitrogen in the soil
    6. Too much weed like especially barnyard grass grows in the field

    How to prevent false smut from happening?
     
    Preventative controlling of false smut is a must to prevent the risk of less production and lower value of your rice or wheat. Here are some basic handlings according to previous section.
     
    1. Use certified less susceptible seed varieties
    2. Treat the seed 10 minutes at around 52°C
    3. Do the seeding of rice or wheat as early as you can. According to research, rice or wheat seeded in April is less contaminated by the fungus than those in May.
    4. Plough your field no less deeper than six inches and dry the soil under sunshine during summer
    5. Get rid of weeds especially barnyard grass. Barnyard grass is an alternative carrier that tends to spread the disease
    6. Use moderate nitrogen
    7. Spraying only once recommended fungicides 5 – 7 days before flowering
    8. Check the field after flowering and remove detected smut false
