Frost Injury To Wheat, S P. Loss

Journal of the Department of Agriculture, Western Australia, Series 4

Frost injury has not been a major concern to the Western Australian wheat industry despite causing spectacular but irregular crop losses on some farms.

The development of suitable herbicides, direct drilling technology and the adoption of early flowering varieties in the late 1970s and early 1980s led to wheat crops being sown and flowering earlier than previously. This resulted in an increase in the incidence of frost damage.

Research into frost indicates that most wheat producers face low to moderate risks of yield loss caused by frost. However, individual farms in particular years can suffer devestating widespread losses. Grost injury …

Late spring frosts commonly reduce yields and affect the quality of grain in wheat crops, especially in the southern, eastern and north-eastern districts. The damage is usually localised on individual farms, but is sometimes widespread.

Barley, and oats to a lesser extent, are also affected. Average losses of wheat in Western Australia have been estimated at 3 to 5 per cent, per year, or about 2 million bushels on current production figures.

Frost Injury Of Wheat, S C. Chambers

Journal of the Department of Agriculture, Western Australia, Series 4

Late spring frosts commonly reduce yields and affect the quality of grain in many wheat crops- especially throughout the southern, eastern and north-eastern districts.

The damage is usually localised on individual farms, but occasionally widespread damage occurs in the south of the State.
