YELLOW RUST

About:

• Yellow Rust disease appears as yellow stripes of powder or dust on leaves and leaf sheaths of the wheat crop. This yellow powder comes out on clothing or fingers when touched.
  
  
• The disease can spread rapidly under congenial conditions and affects crop development, and eventually the yield.
  
  
• Yield due to the disease can be affected by between 5 and 30 per cent. This occurs when the rust colonies in the leaves drain the carbohydrates from the plant and reduce the green leaf area.
  
  
• In India, it is a major disease in the Northern Hill Zone and the North-Western Plain Zone and spreads easily during the onset of cool weather and when wind conditions are favourable.
  
  
• Rain, dew and fog favour the disease’s development.
