Pests & Diseases

Introduction

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. Since the first crops were grown in the colony with varieties from England local selections were made and disease control practices followed traditional homeland practices. 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.
