Fungal Disease Black Stem Rust of Wheat by Dr. Subrata Giri
Introduction Black stem rust, caused by the fungus Puccinia graminis f. sp. tritici, is a devastating and economically important disease that affects wheat and other cereal crops. It has historically been responsible for severe crop losses, leading to famines and food crises. The disease is highly destructive and spreads rapidly, posing a significant threat to wheat production worldwide. Early detection and effective management strategies are crucial to mitigate the impact of black stem rust on wheat crops.
Symptoms Small, dark brown to black pustules on leaves, stems, and spikes. Reddish-brown spores inside mature pustules. Yellowing of infected leaves and premature senescence. Stem and spike infection, leading to reduced grain filling. Significant yield losses and economic impact on wheat production.
