Recent rains may be interfering with cereal and canola harvest progress in some areas, but excess moisture problems are not as big of an issue for corn crops this late in the season.

Manitoba Corn Growers Association agronomist Morgan Cott says high moisture is a bigger concern for corn earlier in the season, and since crops are so far along, excess water shouldn't affect yield at this point. In some cases, Cott says the abundant rains could affect the quality of the grain, but it's hard to tell at this point.

"[Corn] is still trying to fill right now, so the size of the cobs are all set, it's just whether it can finish off completely or dry down completely and have that amount of time before frost or before black layer forms," she says.

Cott says overall it would still be best if the puddles dry up and the moisture goes down.

"As long as [the moisture] doesn't stick around and we keep on getting more and then nobody can get out on the fields," she says, "that would be the worst case scenario, in my opinion. Then everybody would be waiting until freeze to get onto the field, period. So if the moisture stays for a long time, then that's a concern, but I can't really see that happening."

According to Cott, the worst weather corn could face right now would be a frost.
