Yellow Rust – Background Context
Yellow Rust, the particular crop disease, found on wheat crops, is spreading in the north part of India at lightning speed, very recently Yellow Rust as observed and detected in the State of Punjab and State of Haryana and created havoc in farmers' communities.
What is Yellow?
Yellow colour strips of a substance similar to some sort of powder appear on the leaves of the wheat crop.
Yellow Rust happens when the yellow rust covers most of the wheat leaves and removes the carbohydrate from the wheat crop, eventually reducing the green area. Environmental and weather conditions containing moisture (Fog, Rain and dew drops) make favourable conditions for this “yellow Rust” disease to grow and spread.
“Yellow Rust” Spread?
Yellow Rust disease can spread very rapidly in its favourable conditions (wet and moisture environment) and devastate crop development and damage the entire yield. So far it is seen that yields due to “Yellow Rust” disease may get affected between 5% to 30%. It is a huge number considering the presence of diseases found in wheat crops.
Is it detected elsewhere in India?
Yellow Rust is mostly found in the northern part of India, especially in the hilly region and north-western plains. It spreads mostly during the cool and wet conditions, during which wind conditions are also favourable.
Growing the genetically modified wheat crop is considered to be the preferred and cost-effective method to control this infamous “Yellow Rust”. The new, disease-resistant gene of the wheat crop now seems ineffective due to the adaptation of virulence of some particular tolerant genes, making the wheat crop variety more susceptible to “Yellow Rust”.
