Over the years the seriousness of various wheat diseases has ebbed and flowed depending upon the weather conditions, the rotations (break crops) and the resistance or tolerance of the cultivars.

Bunt and rust soon became serious problems and treatments developed and selections from local plants made.
Vermin such as mice locusts and white snails have also created challenges for farmers.
