Facts for Prelims (FFP)

Context: The Indian Institute of Wheat and Barley Research (IIWBR) has urged wheat farmers to remain vigilant against yellow rust, a pest that historically appeared in some districts of Haryana during this period.


Yellow rust, a fungal disease, adversely impacts wheat crops by creating yellow stripes on leaves, hindering photosynthesis and causing grain size reduction. Typically prevalent in cool weather, especially in the northern hills and north-western plains zone, the recent combination of rain, temperature rise, and humidity creates favourable conditions for yellow rust development.


If yellow rust is observed, recommended measures include spraying fungicides such as Propiconazole or Tebuconazole to prevent further spread. The advisory emphasizes using an alternate fungicide if applied last year, especially during dry conditions.
