Summer

Wild radish (Raphanus raphanistrum) is highly competitive in crops and can cause a yield loss of 10-90%.

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.

Frost occurs on clear nights in early spring when the air temperature drops to 2°C or less. Crop damage from frost may occur at any stage of development but is most damaging at or around flowering.

One method of weed control is to remove weed seeds in the fallow, stubble and pre-sowing phase. This can be achieved by encouraging the germination of weed seeds and then subsequently killing seedlings or destroying seeds and reducing seed viability.
