Check out this picture I took of maize sitting somewhere in eastern Ukraine, click on the picture to make it bigger.I made a road trip at the weekend from Kiev to Russia, all 500km there and 500km back and most of the maize looked like this.
To put a figure on it I would estimate that 70% of what I could see from the road between Kiev and Sumy was in this condition or worse.
The dry weather has affected establishment, subsequent growth and pre-emergence chemicals have failed to activate.
A lot of the wheat wasn't doing too well either.
