Powdery mildew is a fungal leaf disease that reduces yield and grain quality in susceptible wheat varieties.
Permanent raised beds are a practical and economic means of managing some waterlogged sites in wetter areas of the Western Australian grainbelt.
Waterlogging causes clay to disperse in sodic soils, leading to soil structure collapse.
Frost risk occurs virtually every year across southern and eastern agricultural regions. Actual occurrence of frost is determined by location and landscape factors as well as climate.
