Yellow rust is a fungal disease that turns the leaves of the crop to yellow and inhibits photosynthesis, which can eventually result in a decline in wheat crop productivity.
Rust pathogens of wheat (Triticum beautivum) and tricetale (Triticosyl) are among the most important crop pathogens, posing a persistent threat to crop production. Three rust species infect wheat and are distributed globally, namely, yellow (striped), caused by Puccinia striiformis, p. Rust due to trisitina and stem (black) rust. P. Griffis f.sp. tritici. The three forests have suffered a lot due to disease epidemics in different regions, years and environments. Yet yellow rust in particular has been reported to be a growing problem with repeated cases of invasion worldwide.
