Blast: Pyricularia grisea

Mosaic: Potyvirus

• Severe cases of infection - entire crop give a blasted or burnt appearance- hence the name "BLAST"
• Severe cases - lodging of crop (after ear emergence)

• Neck region of panicle develops a black color and shrivels completely / partially grain set inhibited, panicle breaks at the neck and hangs

• Nodes become black and break up

• Spray any one of the fungicides Carbendazim 500 g or Iprobenphos(IBP) @ 500 ml/ha. First
  spray immediately after noticing the symptoms. Second and third sprays at flowering stage at 15 days interval to control neck and finger infection.
• Foliar spray with Aureofungin sol 100 ppm at 50% earhead emergence followed by a second spray with Mancozeb
  1000g/ha or Pseudomonas fluorescens @ 0.2% 10 days later

• Initial symptoms of mottle streak disease appear around 45 DAS in funnel leaves as small sparse chlorotic specks.
• Later the specks coalesce leading to short streaks.
• Yellowing of plants in severe infection.
• Infected plants produce more of nodal branches and unproductive tillers.
• Failure of earhead emergence with sparse grains are noticed during initial and late infection.

• Rogue out the affected plants.
• Spray any one of the insecticides like Methyl dematon 25EC 500 ml/ha on noticing symptoms and repeat twice if necessary at 20 days intervals for control of insect vectors
