Frost damage to braocacre crops is a significant annual production constraint for localised parts of the Western Australian wheatbelt.
Wheat is highly susceptible to frost damage between ear emergence and flowering – often termed reproductive frost.
Frost occurs on clear nights in early spring when the air temperature drops to 2°C or less.
One method of weed control is to remove weed seeds in the fallow, stubble and pre-sowing phase.
