Some soybean growers in the region are replanting or thickening up some fields this week, thanks to frost damage.
OMAFRA's Brian Hall says damage is patchy throughout the fields and, in some of those patches, not all the plants have been killed.
Soybeans which had not yet emerged were not damaged.
Corn fields are showing damage that varies from frosted leaves to all the above ground plant being frosted off.
But Hall says those fields will recover.
The OMAFRA specialist says corn is now in a critical stage for weed control.
Yield loss in corn caused by weeds can be reduced to less than 5 per cent by maintaining good weed control during this critical growth period.
