An estimated 82% of French grain maize crops were in good or excellent condition by Sept 11, up from 80% the previous week, farm office FranceAgriMer said on Friday.

That compared with a 43% score a year earlier, the office said in a weekly cereal crop report.

Farmers had harvested 1% of the French grain maize by Sept 11, unchanged from the previous week. That compared to 13% a year earlier and a five-year average of 4%.
