This year the early frost is particularly scary in the Peace Region, because most crops are roughly two weeks behind schedule due to the extremely wet weather through June and July and summer time temperatures which were cooler than normal.
The paper quotes Ralph Wright with Alberta Agriculture, as saying it is not yet considered a 'killing frost'" but there's a serious risk of losing millions of dollars’ worth of crop yield.
Mr. Wright is also quoted as saying "Generally, a killing frost is -2C, but it also depends on the amount of time that it sits at ground-level,"
The article adds an e-mail sent out to farmers from the Alberta Canola Producers' Commission, lists relative humidity, and the presence of rain or dew as other factors.
Canola producers in particular are being encouraged to be patient before swathing and a Commission spokesman says crops should be checked for damage six or seven hours after frost, before they do anything.
