About Lesson
  • Eradication of self-sown wheat plants weed hosts, alternate host.
  • Adjust time of sowing.
  • Grow resistant varieties like Kalyanasona, Sonalika, Choti Lerma, Lerma Rojo, Safed lerma, NP 700 & 800.
  • Avoid late sowing ¾ Balanced application of nitrogenous fertilizers.
  • Seed dressing with Plantavax@0.1% followed by two sprays with the same chemical.
  • Spray twice or thrice with Zineb@0.25% or Mancozeb@0.25% or Plantavax@0.1% , at 15 days interval.
  • Fungicide like azoxystrobin at 200g/l + cyproconazole at 80g/l, tebuconazole + tridimenol and tebuconazole were most effective in reducing stem rust. Epoxiconazole at 125 g/l + carbendazium at 125 g/l were reduction of the disease.
  • Potassium carbonate at all concentration ,sodium bicarbonate at 15 ad 20 g/l ,potassium bicarbonate at 10,15 and 20 g/l and ammonium at10,15 and 20 g/l, dipotassium bicarbonate at 20g/l inhibit spore germination by 95-100%. Kcl and Nacl at 10, 15 and 20g/l also inhibit the germination (Azmeraw, Admassu, Abeyo, & Bacha, 2020).
