A cold air mass is forecast to bring a widespread frost to southern Brazil and Paraguay after a stalled front. Most of the safrinha corn in Parana is rated good to excellent, but only about 26% is mature, so the crop remains vulnerable.
The frost threat is larger than an earlier mid-May event.
Frost damage to late-maturing corn in southern Brazil could cut yields and tighten export supply, which is supportive for corn prices.
